These best self cleaning litter box reviews are for those cat moms and dads who absolutely hate having to sift through their pets’ litter. These litter boxes are the solution for you if you belong to this group; they all come with a mechanism that does most (in some cases, all) of the litter-sifting for you.

Omega Paw Self-Cleaning Litter Box

This is easily among the cheapest self-cleaning litter boxes out there—but then again, it’s not totally self-cleaning. This box requires manual assistance to do its job: you still have to roll it onto its side so that the screen and tray construction inside it manages to separate the loose litter from the clumped parts. It’s easy enough to do, but you will likely see problems if your litter doesn’t hold its clumps very well. The clumps can fall apart and pass through the screen, especially if you roll it over too quickly. That said, using the right litter with it and doing the roll slowly actually does the job fairly well. One just wishes it felt a bit more solid at times, but as it is pretty cheap, it’s a bit hard to complain too loudly.


  • Inexpensive
  • Doesn’t require electricity
  • Easy to use despite being manually-assisted


  • Requires you to use really hard-clumping litter
  • Could be made sturdier

ScoopFree Self-Cleaning Litter Box

Designed for use with disposable blue crystal litter trays, this litter box employs a combination of liquid dehydration and automated raking to do its job. The crystals dry up your pet’s waste and the rake deploys 20 minutes after the sensors have detected your cat entering the box—if the cat enters the box again before the 20 minutes are done, the sensors reset the timer.


  • The crystal litter is dust-free
  • Fully automated sifting
  • Rake works well at sifting most of the time


  • Refills for the crystal litter trays can get expensive
  • Crystal trays may not last the 30 days claimed by the manufacturer, especially if your cat is on the large side (with his waste being the same)

This litter box employs sensors and a mechanized rake to do the sifting for you. It actually works quite well, but owners with cats raised to use clumping litter should beware that their pets may not transition smoothly to it. The crystal litter trays used by the product are also not the cheapest. If you’re the type who really wants the litter box to smell clean, you’ll be changing trays well before the 30 days—and that may get pretty costly. Note that the hood in the product’s image is an add-on you have to buy separately.

CatGenie Self-Washing Self-Flushing Litter Box

With washable granules, the CatGenie lets you dump your cat’s excrement down the toilet by liquefying solids and washing away urine. Meant to be set on its cleaning cycle once a day, it allows users to dispose of their cats’ urine and feces in a safe, green way. Once the solids have been separated and the granules washed, they are dried for re-use.


  • Sanitary solution lasts up to 120 washes per cartridge
  • Permanent granules are environment-friendly
  • No bags of litter/excrement to dispose of


  • Cleaning cycle takes 30mins
  • Not ideal for cats with soft poop

This litter box is like a mini-toilet for cats—it’s actually meant to be set up where there’s a water line and a drain. It’s great when it works, but it may not be for you if your cat has soft poop; the rake tends to miss it and it just gets mixed in with the litter… then washed and dried. The result is nothing short of abysmal, so look elsewhere if this applies to your cat.

LitterMaid LM980 Mega

This tray-style litter box has an automatic raking mechanism that kicks into action 10 minutes after the sensors detect activity in the box. The waste is raked into a disposable container with a carbon filter to reduce odor. It can be manually activated, has a removable plastic rake for maintenance, and sports a paw-cleaning ramp for reducing tracking.


  • Large and roomy, with tall sides (28 x 17.7 x 9.8 in)
  • A safety bar stops and reverses the rake mechanism instantly for when the cat jumps in while raking is happening
  • Rake is non-rusting and easy to clean


  • Can be a little noisy when the rake is activated
  • Motor is sensitive to too much strain (often caused by overfilling)

This is the biggest version of Littermaid’s self-cleaning boxes. Mechanism-wise, it’s much like the ScoopFree (see above), although it does have the advantage of allowing you to choose whatever clumping litter you want with it (as opposed to proprietary cartridges). It also has filters to help reduce the smell, which is very nice. It’s not ideal if your cat tends to aim a bit high or pees on the sides, though: the sensor is in the sides, and getting it wet affects its performance. It can also give out if you overfill your box, since the motor will be subjected to too much strain.

Litter Robot 3 "Open Air"

The Litter-Robot Open Air Automatic Self-Cleaning Litter Box makes caring for your cat easier. The first major update to the highly successful Litter-Robot platform, the Open Air is the culmination of the latest technology and 15 years of customer feedback. Once your cat exits, a timer counts down, allowing waste to clump before a cleaning cycle begins automatically. As the globe slowly rotates, the patented sifting system separates the clean litter from the clumps and drops the waste into a carbon-filtered drawer. The globe returns to the home position, leaving a clean, level bed of litter for the next use. Uses clumping litter and kitchen garbage bags. NO SPECIAL ACCESSORIES REQUIRED. The enlarged entryway and litter chamber, along with the self-adjusting cat sensor, accommodate cats weighing 5 lbs. or more. NEW FEATURES: DRAWER FULL INDICATOR: A flashing blue light lets you know when the waste drawer is full, so there's no more guessing. CONTROL PANEL LOCK OUT: Prevent kids and cats from unnecessarily pressing buttons, which could change your settings or cycle the unit. ADJUSTABLE CYCLE TIMER: Choose a 3-, 7-, or 15-minute delay from the time your cat uses the Litter-Robot until it performs a cleaning cycle. 8-HOUR SLEEP MODE: When activated, for a period of 8 hours, your unit will only cycle when the button is pressed manually to prevent disturbances. AUTOMATIC NIGHT LIGHT: Illuminates the litter chamber in low light conditions for elderly cats. BACKUP BATTERY (Sold Separately): The Backup Battery provides up to 48 hours of operation if power is interrupted. Estimated operation time is based on 10 cleaning cycles per day, which is typical for two cats, but results will vary. Backed by a 90-DAY MONEY-BACK GUARANTEE and 18-MONTH FULL WARRANTY. With more than 125,000 customers, over 15 years in business, and three versions of the Litter-Robot on the market, we are confident we have developed the best solution for pet parents to never have to scoop again!

Litter Robot LR II

7 minutes after your cat is detected in it, the Litter Robot starts the clean cycle that rotates the globe and moves the litter through a sifter. The waste goes into a chamber with a trash bag and the globe returns to its old position.


  • Waste container has a decent seal
  • Most inside parts are lined with rubber to reduce sticking
  • Offers On and Off settings if you prefer to initiate the cleaning cycles yourself


  • Doesn’t have a mechanism to stop cats from entering it when it’s in the middle of cleaning (which means cats can relieve themselves on the sifting grate by accident)
  • A bit pricy

A pricy self-cleaning litter box, but it’s actually a very good option nonetheless. A rotating globe and an integrated grill are combined with weight sensors and a well-sealed chamber in it, and the system works quite beautifully. It can be a bit noisy, but you can put it on Off mode if you need to sleep.


There are a lot of factors to consider when making your decision, including whether or not your cat is willing to use non-clumping litter and if he shall fit comfortably in the litter box you’re looking at. Assuming a generic cat is willing to use any type of litter, though, the best buys here are the Omega Paw for its inexpensiveness and the LR3 for the general quality. Both are effective in their own ways, even if they belong to different ends of the pricing spectrum. People with money would likely prefer the LR3, but its price really takes it out of the running for a lot of others—hence the Omega Paw manages to share top spot with it, out of sheer value for money.
