Pros & Cons

  • Jumbo interior (23.6x15.7x15.7) lets large cats turn and dig freely
  • 80L outer capacity holds up to 40L litter for deeper burying
  • Non-porous stainless steel tray resists odors and wipes clean easily
  • 3-in-1 modular design converts to enclosed, semi-covered, or open modes
  • Lockable dog-proof latch secures cat privacy and blocks curious dogs
  • Tall seamless sides plus carbon filter reduce splashes and control odors

Cons

  • Tall sides may challenge very small kittens or arthritic cats without step
Detailed Review

I was impressed by how this Extra Large Stainless Steel Litter Box combines serious capacity with durable construction, making even the messiest diggers feel at home. The size and metal finish are what really set it apart.

With dimensions of 23.6 x 15.7 x 15.7 inches and an 80 liter body volume, the Jumbo size lets big cats turn and bury without crowding. It can hold up to 40 liters of litter for deeper burying, which means less frequent refills and calmer, more natural elimination for multi cat households.

The Stainless steel tray is non porous and resists odors and stains, so cleanup is fast and hygienic. The non stick, scratch resistant surface wipes clean easily and will not trap residue that causes smells, which I appreciated after a week of heavy use.

The 3 in 1 modular design is clever and practical: set it fully enclosed, semi covered, or use it as an open pan. The front entry with top exit layout is thoughtful for multi cat flow, and the lockable dog proof latch actually keeps curious dogs out while protecting cat privacy.

Built in odor control with a carbon filter plus tall, seamless walls helps prevent leaks and splashes, and the included step board, scoop with holder and non slip pads reduce tracking and keep the area tidy.

Who this is for: owners of large cats, multi cat homes, seniors who need a low step, or anyone tired of frequent litter maintenance.

One minor trade off is weight: the metal pan is heavier than plastic and may be awkward to move when full.

Overall verdict: if you want a rugged, hygienic, low maintenance option for larger or multiple cats, this litter box is a strong, practical choice.

Pros & Cons

Pros

  • Neutralizes urine and litter odors with corncob granules and essential oils.
  • Pet-safe formulation designed for use around cats.
  • Absorbs moisture to help reduce odor between litter changes.
  • Easy sprinkle-on granules for quick, no-mess odor control.
  • Compact 12 oz bottle provides multiple treatments.

Cons

  • Essential oil scent may irritate sensitive pets or people.
  • 12 oz size may be small for multi-cat households.
  • Granules may need mixing into litter for best effectiveness.
Detailed Review

I was skeptical at first but Rocco & Roxie Litter Box Odor Eliminator surprised me with how quickly it neutralized urine smells without overpowering my home. The small 12 oz jar hides a powerful, natural approach to litter care.

The product uses natural corncob granules that actually absorb moisture and lock in odor, so litter stays fresher between scoops. The granule blend feels lightweight and mixes easily into existing litter rather than clumping into a mess.

A subtle essential oil blend adds a clean scent that masks ammonia without irritating my cat. Because it is designed as a granule odor absorber, I noticed fewer lingering smells and less need to change the entire box as often.

Label claims about being safe for kitty aligned with my experience; there was no aversion from my cat and no tracking issues on floors. Application is simple: sprinkle a thin layer over the litter after cleaning and refresh during routine maintenance.

This product is best suited for multi cat households, apartment dwellers, and anyone who wants an easy, natural deodorizer without switching litter brands.

One minor consideration is the scent may be noticeable to particularly sensitive noses, and a 12 oz container can feel small for heavy use households.

Overall it is an effective, user friendly deodorizer that balances natural ingredients with real performance; I recommend it for most cat owners who want cleaner smelling litter without harsh chemicals.

Pros & Cons

Pros

  • App control with scheduling and full-bin alerts over 2.4GHz Wi-Fi
  • Open-top roomy interior supports cats 3.3–27.6 lb comfortably
  • Automatic pause using 3 infrared pairs and 4 weight sensors for safety
  • Ultra-quiet operation reduces stress and nighttime disturbance
  • 10.5L pull-and-wrap waste bin simplifies disposal and reduces maintenance

Cons

  • Requires 2.4GHz Wi‑Fi and app setup; no 5GHz support
  • Open-top design may allow more litter scatter and less privacy
  • Not suitable for cats over 27.6 lb
Detailed Review

I tested the Invengo Automatic Cat Litter Box and what grabbed me first was how it turns a messy chore into a mostly set and forget routine with smart controls and a neat waste system.

With SMART APP CONTROL I scheduled cleanings, tracked litter usage, and received full-bin alerts right from my phone, which saved time and reduced surprises. The setup is straightforward but note that it only works on 2.4GHz networks and the app needs Bluetooth and location permissions during pairing. The SPACIOUS OPEN-TOP DESIGN gave my cats room to move and better airflow, comfortably fitting kittens and adults from 3.3 to 27.6 pounds. I appreciated the SAFE & INTELLIGENT PROTECTION of three pairs of infrared sensors and four weight sensors that pause cleaning if a cat reenters, which feels reassuring. Operation is impressively quiet, so no stressed cats or startled naps when the unit cycles.

The PULL & WRAP WASTE SOLUTION with a 10.5 liter waste bin and odor control made emptying tidy, and the included garbage bag rolls meant I could leave maintenance for up to around two weeks depending on use. The mechanism keeps odors down and handling simple.

This unit is best suited for busy pet owners, multi cat households, and people who want a low touch solution that still keeps a clean home. It is also good for owners with kittens thanks to the roomy entry.

A minor consideration is the strict requirement for a 2.4GHz Wi Fi network and app permissions during setup, which may complicate installation in some homes. Overall, I recommend the Invengo for its reliable cleaning performance, thoughtful safety features, and real time app convenience for everyday life with cats.

Pros & Cons

Pros

  • Lasts up to twice as long as leading clay litters
  • Quick-clumping forms tight clumps for easy scooping
  • Flushable and septic-safe in well-maintained systems
  • 99% dust-free and lightweight, minimizing tracking and dust
  • Made from whole-kernel corn — natural, chemical-free, renewable

Cons

  • Higher upfront cost than many clay litters
  • May need more frequent full changes in multi-cat households
  • Not recommended to mix with non-clumping litters
Detailed Review

After testing a 32 pound bag of Worlds Best Cat Litter Comfort Care Unscented I was struck by how a natural corn formula can turn a messy chore into a fairly pleasant routine. It handles odor and clumping without the heavy feel of clay alternatives.

I noticed right away that LASTS 2X LONGER is not just marketing copy but a practical benefit: the granules absorb urine more efficiently so one bag stretches farther and saves money over time. The OUTSTANDING ODOR CONTROL kept the litter box neutral even with two cats, and 99% DUST FREE performance meant less airborne dust and cleaner floors. Quick clumping made scooping fast and tidy, which reduced the time I spent maintaining the box.

The litter is also flushable and septic safe when used in well maintained systems, which is a real convenience for households that prefer not to bag waste. Being made from whole kernel corn makes it PET PEOPLE AND PLANET FRIENDLY since there are no artificial perfumes or clay dust, and the lightweight granules reduce tracking.

This product is best suited for owners of one or two cats, allergy sensitive households, and anyone who values low dust and long lasting performance over the cheapest upfront option.

A small consideration is that some cats take a few days to adjust to corn based texture, and the initial price per bag can be higher than basic clay litters even though it lasts longer.

Overall I recommend Worlds Best Comfort Care for cat owners who want efficient odor control, easy scooping, and a more natural, low dust alternative to clay litter. It earns a solid thumbs up for daily convenience and long term value.

Pros & Cons

Pros

  • Spacious interior fits Maine Coons, Ragdolls, and multiple cats comfortably
  • 12" high overlapping sides keep urine and litter contained, reducing spills
  • Stainless steel resists odors and wipes clean with minimal effort
  • Non-slip bottom pads prevent the box from sliding during use
  • Secure buckles and rounded edges reduce leaks and injury risk
  • Includes a large scoop to simplify daily cleaning

Cons

  • Heavier and less portable than typical plastic litter boxes
  • Extra-large size uses more litter and requires more floor space
  • Metal surface can feel cold or noisy for some cats
Detailed Review

I recently swapped my plastic tray for the Extra Large XXL stainless steel litter box and it immediately solved scatter and smell issues. The heavy gauge metal and tall walls make it feel industrial but reliable.

What sold me first was the Extra Large Size 26 inch by 18 inch footprint and roomy 12 inch depth. Big cats like Maine Coons and Ragdolls can turn and dig without spilling litter, and the 12 Inch High Sides plus upgraded buckle tight overlapping edge prevent urinary leakage that I had from seam gaps in other boxes.

Cleaning is refreshingly simple because the stainless surface does not absorb odors or stain. The Easy to Clean finish wipes and rinses off with little effort, and the included large scoop makes daily maintenance faster. I also appreciated non slip bottom pads and safe rounded edges that keep the box steady and prevent accidental scrapes.

This box is ideal for multi cat homes, owners of large breeds, and anyone tired of replacing flimsy plastic trays. It is also a good option for people who prioritize durability and hygiene.

One minor downside is that the steel is heavier and bulkier than plastic, so it takes more effort to move or store and may feel cold under paw in winter.

Overall this is a sturdy, low odor, low scatter solution I can recommend for serious cat households looking for a long lasting upgrade.

Cons

  • Heavier than plastic boxes, may be awkward to move when full
  • Metal surface can feel cold or noisy, possibly deterring some cats
  • Enclosed lid may be restrictive for very large or entry-averse cats
Detailed Review

After testing the Jotesnew 2 Pack XL Stainless Steel Cat Litter Box I was struck by how immediately clean and sturdy the setup feels. The roomy footprint and solid lid make daily litter care noticeably less chaotic.

What stood out first was the Stainless Steel Non-Stick Surface, which resists odors and stains far better than plastic and rinses clean in seconds, cutting down scrubbing time. The Enclosed & High-Sided Design with 12 inch walls and a secure lid kept litter scatter and urine splashes contained, which is a real win for active diggers. I also appreciated the Easy To Clean approach overall: the metal tray does not absorb smells, the package includes a scoop and stand, and each box holds about 20 liters of litter so refills are less frequent. Small rubber feet and upgraded buckles helped the box stay put on tile during use, so it did not slide when my larger cat hopped in.

This product is best suited for households with large cats or multiple cats, owners who prefer low odor materials over plastic, and anyone who values durability and easier sanitation in a litter area.

One minor consideration is weight and storage: the stainless steel and reinforced lid make these boxes heavier and more awkward to move than lightweight plastic alternatives, so plan placement before filling.

Overall I recommend the Jotesnew XL set for those wanting a durable, tidy, and low maintenance litter solution for big or multiple cats. It feels like a long term upgrade for cleanliness and convenience.

  • Prevents odor absorption for minimal lingering smells
  • Smooth non-stick surface cleans easily with a quick wipe
  • 10-inch high sides plus lid reduce litter scatter and urine splash
  • Supports up to 20 lb of litter; roomy for large cats
  • Rolled smooth corners protect paws and prevent scratching

Cons

  • Heavier than plastic boxes, less portable
  • Lid may deter shy cats or limit entry for some large cats
  • Shows water spots/fingerprints; needs occasional polishing to maintain shine
Detailed Review

I expected a plain litter box but the XL Stainless Steel with lid surprised me with a dry, odor free finish and a sturdy, kitchen grade feel.

After using it for a week I appreciated the food grade stainless steel surface that truly does not absorb smells and cleans up in seconds. The non stick finish means clumps and urine wipe away with minimal effort, so daily maintenance is faster and deeper cleaning is easy when needed.

Safety and durability stood out too. Corners are carefully polished and edges rolled so cats do not get nicked, and the heavy gauge metal feels built to last. The included mat and scooper keep litter tracking down, and the cover prevents scatter so bathrooms and enclosures stay tidier.

At 23 by 14.6 by 10.2 inches with high sides this pan fits large breeds up to 20 pounds and even small multi cat setups. I noticed big cats can turn around comfortably and the box holds a generous amount of litter without tipping.

This is great for owners who want longevity and easy sanitation, beginners who want low maintenance, or anyone placing a box inside furniture or enclosures. A minor consideration is the weight and metallic feel which may be noisy or cold for shy cats when compared with plastic.

Overall this is a solid upgrade from plastic pans for anyone prioritizing hygiene and durability; I would recommend it for cats and owners looking for a long term, low odor solution.

Pros & Cons

Pros

  • Durable stainless steel resists deformation and odor retention
  • Spacious interior fits large cats and holds litter for 15–30 days
  • Modular enclosure converts between enclosed and semi-open setups
  • Switchable top or front entry to suit cat mobility and preferences
  • Includes litter mat, dual-purpose scoop, and filter pedal
  • Non-stick stainless surface simplifies cleaning and reduces stuck-on waste

Cons

  • Heavier than plastic alternatives, harder to move
  • Metal construction can be noisier when cats enter or during scooping
  • Best performance needs about 20 lb litter, increasing refill cost
Detailed Review

After a week of using the Stainless Steel Litter Box with Lid I was impressed by how different a metal box feels compared with plastic. It is solid, easy to clean, and designed like a proper long term solution for litter maintenance.

Because the shell is stainless steel the first thing I noticed was how odors do not cling and waste does not stick the way it often does to plastic. The Stainless Steel durability means I can foresee years of use without warping, and wiping and rinsing are much faster during daily maintenance.

The enclosure is modular so I tried both setups. The enclosed mode keeps litter and smell contained while the semi enclosed mode lets skittish cats feel safer coming and going. The adjustable snap settings make switching between top entry and front entry straightforward. I appreciated the Dual Entry Options for accommodating older cats and more energetic jumpers.

At 23.6 by 15.7 by 16 inches it is roomy enough for larger cats, and the capacity lets you go longer between full cleanouts. The included mat, dual purpose scoop and filter pedal felt like thoughtful extras that help reduce scatter and make scooping less messy. The Large Size and included accessories make this a near all in one litter solution.

One consideration is weight and handling. The metal construction makes the unit heavier than plastic and initial assembly can be fiddly for one person.

Overall this is a robust, low odor, low maintenance option ideal for owners of medium to large cats or those who prefer a long lasting alternative to plastic. I recommend it for anyone prioritizing durability and cleaner daily upkeep.

Pros

  • Built-in charcoal filter neutralizes tough litter odors
  • Hooded enclosure reduces litter scatter and prevents spray leaks
  • Flip-top front and snap latches enable fast, hassle-free cleaning
  • Non-stick interior minimizes litter buildup from spraying
  • Front-entry design offers easy cat access and tidy placement

Cons

  • May feel cramped for very large or tall cats
  • Charcoal filter requires periodic replacement, adding ongoing cost
  • Enclosed design may not suit cats that prefer open boxes
Detailed Review

I was surprised how well this Natures Miracle hooded flip top litter box reduced odors and kept litter scatter under control. It feels like a thoughtful upgrade over basic trays.

The HOODED ENCLOSURE gives cats privacy while keeping kicked litter contained and reducing mess on floors; during my use I saw far less tracking around the box. The BUILT-IN CHARCOAL FILTER did a noticeable job neutralizing smells, so the room stayed fresher between cleanings. For maintenance the unit shines: an EASY TO CLEAN flip top front opening and snap latches made daily scooping and deep cleans fast, and the non stick interior prevented litter buildup from spraying.

Design is simple and practical with front entry access that most cats accept quickly. The box is roomy enough for average adult cats and the enclosed shape also reduces visual clutter in a living space.

This litter box is best for busy pet owners who want better odor control without complicated setups, and for households that appreciate quick, low effort cleaning routines.

A minor consideration is filter upkeep; replacement charcoal filters are needed periodically to maintain performance and add ongoing cost. Very large or long legged cats may find the 11.75 inch height a bit low.

Overall, this is a reliable, well designed option that blends odor control with practical cleaning features. I recommend it to anyone seeking a cleaner, less smelly litter area without extra fuss.

Pros & Cons

Pros

  • Absorbs and neutralizes common litter box odors
  • Works alongside existing litter to extend freshness
  • Light fresh scent reduces odors without overpowering
  • Dry crystals stay in place to minimize tracking and mess
  • Easy-pour container enables quick, no-fuss refreshes during scooping

Cons

  • 15-ounce size may require frequent replacements in multi-cat homes
  • Scent could bother highly scent-sensitive people
  • Not a substitute for regular full litter changes
Detailed Review

I tried Fresh Step cat litter crystals to see if they really keep litter areas fresher between full changes. Right away I liked the simple sprinkle application and the light, clean aroma that does not overwhelm the room.

These crystals deliver ODOR CONTROL SUPPORT by absorbing and neutralizing common smells, which made daily scooping less urgent on my schedule. The product is clearly LITTER BOX COMPATIBLE, designed to be layered over existing litter so you do not have to replace what is already in use. The FRESH SCENT FORMULA provides a subtle freshness that masks odors without being cloying, and the dry crystal form stays put instead of turning into a messy paste. The easy pour container makes quick refreshes during routine cleaning straightforward, and in a multi cat home the crystals helped extend time between full litter replacements while keeping the area more pleasant for guests.

This product is best suited for apartment dwellers, busy households with multiple cats, and anyone who wants low effort odor management that fits into regular scooping habits. It is also a practical choice for owners who prefer a dry option over sprays or liquids.

One minor consideration is that the light scent may not fully neutralize very strong or long standing ammonia odors, so households with severe odor issues may still need more frequent full litter changes or a stronger solution.

Overall, Fresh Step cat litter crystals are an easy to use, low fuss deodorizer that genuinely helped freshen my litter area. I would recommend them for everyday odor support and for multi cat homes looking to reduce frequent full litter replacements.

How to really stop ammonia and urine smell

Picking the Best Litter Boxes For Smell starts with matching the box design to the litter and to your home’s airflow. Covered or fully enclosed systems trap odors inside when there’s little air exchange; that can make ammonia smell more concentrated until you scoop or a filter vents it out. Top‑entry boxes reduce tracking and contain scatter while allowing better passive ventilation through the single opening, and open, ventilated pans let ammonia dilute into the room instead of sitting inside a sealed chamber. In short: sealed systems can contain odor if they include active ventilation or a strong filtration strategy; otherwise they can amplify it between scoops.

Litter pairing matters. Silica/crystal litters are excellent at locking fresh urine odors and are often the best first line for single‑cat or light multi‑cat use—use shallower beds (about 1–2 inches) so crystals trap moisture. For true multi‑cat ammonia control, heavier clumping clays with enzyme additives neutralize ammonia as well as clumps do; these perform best at greater depth (roughly 3–4 inches) to give solids and urine room to be absorbed and covered. Deep beds also help for heavy use—shallow trays in a multi‑cat household will saturate faster and release smell.

Beware common filter failures. Inexpensive carbon pads frequently underperform in small apartments or homes with multiple cats because they saturate quickly; many will be ineffective after just a few weeks in high‑load situations. Expect to replace decent carbon filters roughly every 1–3 months depending on use, and upgrade to thicker or multilayer filters for real results.

Placement and airflow are low‑cost fixes that cut persistent odor: put multiple boxes on different floors or rooms (one per cat plus one spare), avoid locating them next to living rooms or bedrooms, and position boxes near a window, exhaust fan or other fresh‑air source when possible. Basements can work if ventilated; closed closets often make smells worse. For multi‑cat odor control, aim for spread, airflow, and the right litter‑box pairing.

Multi‑cat odor control checklist:

  • Box type: ventilated open pan or large sealed system with active ventilation for heavy loads.
  • Litter type: crystals for light use; deep clay clumping + enzyme additives for multiple cats.
  • Filter strategy: quality carbon/multi‑stage filters replaced every 1–3 months; avoid cheap single‑use pads in high‑load homes.

Built for heavy use — durability, capacity and reliability features

When you search for the Best Litter Boxes For Smell in a multi‑cat home, durability and uptime matter as much as odor control. Prioritize thicker, higher‑gauge plastics that don’t flex or crack under repeated cleaning and heavy traffic. Look for reinforced hinges and latches that tolerate daily opening, rust‑resistant metal components (screws, fasteners), and heavy‑duty entry ramps or walkways that won’t warp. These small construction choices prevent failure modes that lead to messy outages.

Size and capacity are practical: for two or more cats, aim for pans with a generous footprint so cats can turn and dig—typically at least in the low‑20‑inch length range and 16–18 inches wide, and deep enough to hold a 3–4 inch litter bed. For automatics, high‑capacity waste trays matter: a larger holding bin means less frequent full cleans and less chance of overflow, which reduces smell. Bigger capacity directly lowers how often you need to empty and deep‑clean.

Common automatic failures reported by users include jams from firm stools, sensor fouling from litter dust or debris, and motor wear from constant cycling. Models that mitigate these risks include self‑diagnostics (error codes), easy‑access removable parts for clearing jams, and motors rated for higher duty cycles. Look for designs that allow manual override so you can use the box if the automatic function fails.

Before buying, ask about warranty length, what parts are covered, and how readily replacement trays, motors, and filters can be purchased. Expect brands that support multi‑cat homes to offer at least a year warranty and to stock consumables. Replacement and repair practicalities are critical: modular components and readily available replacement trays or service centers mean short downtime. If a unit requires factory service with long lead times, the whole household suffers—so confirm parts availability before committing.

Reduce daily scooping and tracking — cleaning systems and routines that work

There are three practical ways to reduce daily scooping: sifting trays, self‑raking automatics, and rotating/robotic units. Sifting trays cut time by separating clumps when you lift and dump, but you’ll still hand‑scoop firm stools—expect modest reductions in labor. Self‑raking automatics can reduce daily scooping to every 2–3 days in multi‑cat homes, but they require regular checks, filter changes, and occasional jam clearing. Rotating or robotic units may push full cleans to weekly for some households, but they need power, periodic drivetrain maintenance, and periodic full sanitation.

Housing a box inside a cabinet or furniture piece reduces visual smell and tracking—and hides an otherwise unwieldy unit in an apartment—but these enclosures must be ventilated. Without vents or a short duct to fresh air, ammonia can build up inside the cabinet and linger when the door opens. If you use cabinetry, drill vents, place a small fan or leave the door slightly open, and choose a box with active filtration when possible.

To stop litter from spreading and dust from carrying odor, use high‑edge or top‑entry boxes, sturdy litter mats, and low‑dust or larger‑granule litters. These reduce the particles that transport odor into carpets or HVAC systems in smaller living spaces.

Here are realistic maintenance plan templates:

  • Heavy multi‑cat manager: scoop solids daily; top off litter every 2–3 days; empty waste tray or crystals weekly; full pan clean and sanitize every 2–4 weeks; replace filters monthly.
  • Apartment renter/one or two cats: scoop every other day; refresh crystals or stir clumping litter weekly; deep clean monthly; replace filters every 6–8 weeks depending on load.
  • Low‑maintenance preference: use crystal litter in a high‑capacity sealed unit, scoop 2–3 times weekly, replace crystals every 2–4 weeks, and keep a spare disposable liner on hand.

Troubleshooting common issues: if an automatic jams, power it down, clear the obstruction, and run a manual cycle; check sensors for dust and wipe them clean. If a filter loses effectiveness, replace it with a higher‑quality multi‑layer carbon or activated charcoal filter and shorten the replacement interval. If a covered box starts smelling within hours, increase air exchange, add enzyme neutralizer to the litter, or switch to a litter better suited to high urine load—don’t rely on a cheap carbon pad alone.

Which option fits you: multi‑cat homes, apartments, budgets and mobility needs

Choosing the Best Litter Boxes For Smell depends on your household. For a heavy multi‑cat manager, the best archetype is either a large sealed system with active ventilation or a high‑capacity automatic paired with a deep clay clumping litter that includes enzyme additives; add silica trays nearby for supplemental odor control. For apartment renters, top‑entry boxes or furniture‑enclosed systems with low‑tracking litters (large granule or low‑dust formulas) keep odor and mess contained without dominating the living area.

On a budget: pick a roomy open pan with high sides, a top‑entry option if tracking is a problem, and a mix of clumping clay and occasional crystal top‑ups. Clean more frequently to compensate for lower tech—daily scooping and weekly full cleans stretch performance without premium costs.

For people with allergies or mobility challenges, prioritize low‑dust litter formulas, sealed systems or trusted automatics to reduce handling, and insist on solid warranty and good customer support. Mobility needs often favor top‑entry alternatives or units with lower step‑in heights and easy access panels. Ask sellers about replacement parts and return policies before you buy.

Do this, don’t do this — quick rules by persona:

  • Multi‑cat: do add extra boxes; don’t rely only on cheap filters.
  • Apartment: do use top‑entry or furniture housing; don’t tuck a box in an unventilated closet.
  • Budget buyer: do invest in better litter and mats; don’t skip daily scooping.

Decision checklist — primary pain → recommended box → ideal litter → one maintenance action: Odor? Large sealed or automatic → deep clumping + enzymes → daily scoop; Tracking? Top‑entry + mats → large‑granule litter → vacuum weekly; Cost? Open pan → mix of clumping & crystals → weekly deep clean.
