7 Best Self-Cleaning Litter Boxes of 2021

The ChillX AutoEgg’s domed cover practically eliminates dust and odor and it easily fits under a desk or in a corner. Even a timid cat won’t be startled by the super-quiet slow-moving rake as it scoops clumps into the waste drawer – it can store up to a week’s waste. The touchscreen records your cat’s bathroom habits so you can monitor its health. During our tests, cats chose the AutoEgg over clean non-mechanized litter boxes.

Cats over 15 pounds might feel confined by the hood, so simply remove it. The AutoEgg works with premium clumping litter, and you can line the waste drawer with ChillX’s biodegradable liners or recycled grocery bags. We were impressed with how well it removes clumps, and loved how quick and easy it was to dismantle the AutoEgg to deep-clean. This litter box comes with a 30-day money back guarantee, and a one-year warranty. 

The budget-friendly PetSafe Simply Clean Automatic Litter Box is ideal for smaller cats (up to 15 pounds) although it should be left unplugged for kittens less than 6 months old. The whisper-quiet, slow-moving conveyor system operates constantly, sifting the clumping litter of your choice to remove the waste, completing a full rotation each hour. Recycled plastic bags can be used to line the waste container, eliminating additional cost for accessories. This litter box comes with a 30-day money-back guarantee and a one-year warranty. 

The Litter-Robot 3 Connect allows you to monitor your cat’s bathroom habits (and the level of waste in the receptacle) via its Wi-Fi-enabled app. This litter box works with any premium clumping litter and is ideal for any cats between 5-20 pounds as well as multiple cats, though not for kittens. It is substantially larger than other enclosed litter boxes, so consider your available space. 

Its cleaning mechanism is slightly different than other automatic boxes: The globe rotates after use and deposits clumps and waste into the receptacle below the box. Bells and whistles include a night light, sleep mode, and an additional cycle timer. 

The Litter-Robot 3 Connect has a 90-day money-back guarantee, and an 18-month warranty. In our Cleaning Lab tests, it was easy to set up, worked smoothly, and completely removed the “clumps” we created. 

As its name indicates, the LitterMaid Multi-Cat Self-Cleaning Litter Box is designed for use with multiple larger cats (weighing over 15 pounds). High walls keep cat litter from being kicked out while your cat is covering, and the paw-cleaning ramp helps ensure litter is not tracked out of the box. The electric rake operates through any clumping litter and the receptacle stores up to a week’s mess. Carbon filters in the self-contained waste receptacles keep odor contained with the clumps. This litter box has a 90-day money back guarantee and a one-year warranty for defects. 

Say goodbye to bags of litter and litter dust! A consumer favorite, the PetSafe ScoopFree Ultra Self-Cleaning Litter Box uses pre-filled disposable trays of crystal litter, which have exceptional odor-locking and moisture absorbing properties. Available in three different colors, with a one-year warranty, the hooded litter box also has a health counter to record often your cat uses it, to alert you to possible health problems. 

Five, 10, or 20 minutes after your cat has used and exited the litter box (you get to set the timer), the automatic rake sweeps solid waste into the covered receptacle incorporated in the disposable tray and grooms the crystals so your cat has fresh litter for its next use. If a cat enters during the cleaning cycle, detection sensors automatically reset the rake’s timer. Every few weeks (in a single cat household), simply dispose of the litter tray and replace with a new one. 

Because of the crystals’ moisture-absorbing properties, it’s best not to install this litter box in an area with high humidity, such as a bathroom.  

The CatGenie A.I. eliminates the need for litter completely. This revolutionary litter box uses special granules which are raked to remove solid waste, then rinsed with a sanitizing solution and blown dry, so your cat has clean fresh litter every time it goes. The granules are made from natural materials, which get broken down by bacteria in a landfill or septic tank, making them septic safe. Another consumer favorite, the litter box installs easily in your bathroom or laundry room, using a cold-water hookup and a drain to flush the waste – no plumber necessary. It’s ideal for multiple cats, large or small (but not kittens). A privacy dome can be purchased separately.

The CatGenie app allows you to monitor the frequency of your cat’s bathroom visits, which can help detect early health issues, and provides status updates on the cleaning cycles. (If you don’t need the app, the CatGenie 120 is a lower cost option.) You can select whether you want the cleaning to take place every time your cat uses the litter box or at set times throughout the day. The washable granules (which are biodegradable if flushed) and SaniSolution need to be replenished a few times per year. This litter box comes with a 90-day money-back guarantee and a 2-year warranty. 

Nature’s Miracle is well known by cat owners for their odor control products, and this automatic litter box is no different. A motion sensor detects when your cat has left the litter box, and a rake automatically scoops clumps into odor-controlled receptacles – carbon filters work to keep odor contained. The extra-large box comes with a one-year warranty against defects and accommodates larger or multiple cats. Its high walls prevent litter from being scattered, and a paw-cleaning ramp limits tracking, although most reviewers recognize that a larger mat is necessary to prevent all tracking. The removable rake makes clean-up a breeze, and a handy scoop and rake cleaning tool is included.

Although you can use any premium clumping litter, for an additional fresh linen fragrance, you can use Nature’s Miracle’s brand of super-absorbent clumping cat litter.
