The Whisker Litter-Robot 4 is a self-cleaning litter box that has it all. Eliminating the need to scoop your cat's waste, this robot handles the chores you don't want to do and can cater to multiple cats.

Waste is quickly separated from the fresh litter and disposed of in the waste drawer below. When the waste is full, the app will alert you; simply pull the drawer out, close the bag, and away it goes!

Using the Whisker app, you can easily keep track of your cat's toilet habits and keep an eye on their weight. If any changes to their routine or weight become apparent, the app will let you know. In the meantime, let your feline friends do their business and enjoy a smell-free home.

The Smarty Pear Leo's Loo Too is available in many colors to suit your home (or your cat). Assembly is really easy and there are plenty of accessories you can use like the included liners or a mat to reduce any mess when your cat exits the litter box. Potentially less intimidating than the Litter-Robot 3, small and medium cats won't have an issue entering the litter box, but larger cats may struggle.

When the waste drawer is full, you'll get a notification from the companion app. Simply pull out the drawer and dispose of the waste. But what really sets the Smarty Pear Leo's Loo Too apart is its safety features. Inside there is a radar system, weight sensors, and an anti-pinch sensor. These help to protect your cat inside the drum, ensuring no cleaning cycle commences while they are in there.

Upon cleaning, the Smarty Pear Leo's Loo Too runs at less than 30dB, which is really quiet considering what it's doing. There's also a UV sterilization system that disinfects the inside of the litter box and removes 99 percent of bacteria.

The PetSafe ScoopFree Self-Cleaning Litter Box is possibly one of the simplest devices if you don't want to manually scoop cat waste. Setup takes a couple of minutes and lasts for several weeks before you need to replace the disposable tray. But, this is where the cost could add up. While the litter box itself is reasonably affordable, you will need to invest in further disposable trays in the future.

Daily scooping will definitely be a thing of the past with the PetSafe ScoopFree Self-Cleaning Litter Box. However, it does have a tendency to smell, even though it's advertised as "odor free". You'll need to use crystal litter, too, rather than clumping, since the rake wouldn't be able to work efficiently with clumping litter.

If you find the PetSafe ScoopFree Self-Cleaning Litter Box fits well into your routine, you can invest in additional accessories to make life just that little bit easier. For example, there's a reusable litter tray that saves the expense of disposable trays, or the option to upgrade to the smart version, so yo u can monitor your cat's health.

If you have a large cat or multiple cats, the KungFuPet Self-Cleaning Cat Litter Box might be the best option. It boasts a whopping 60L capacity, supporting cats from 3.3 pounds to 25 pounds. When your furball has finished its business, it can use the convenient pull-out step which features a grill that captures any loose litter on the way out.

The KungFuPet Self-Cleaning Cat Litter Box can handle a range of litter, but clumping litter is recommended to make the process easier. Once turned on, you'll be able to identify the different modes this robot litter box is in by the LED ring indicators. For example, a red light indicates an issue, blue means the machine is UV cleaning to remove odor, and green means clumping is in progress.

When it's time to go to bed, the KungFuPet Self-Cleaning Cat Litter Box can enter sleep mode. Here, it turns to standby mode which switches the lights off and won't perform any cleaning activities. Of course, you can leave the litter box running all day and night if you wish, but there is that peace of mind if you need it.

With four different modes, the CATLINK Self Cleaning Scooper-Pro is incredibly easy for your cats to use. Plus, it's super simple to set up too. Using the app, you can create unique profiles for each of your cats and monitor their daily behaviors. And, since this self-cleaning litter box is suitable for cats of all different sizes and weights, it's perfect for the whole family (of cats).

Like many other robot cat litter boxes, the CATLINK Self Cleaning Scooper-Pro boasts safety protection features so your cats don't get stuck or hurt. The cleaning tunnel rotates to clump and clean the litter, then empties it into the tray below. But what really makes this litter box stand out is its advanced app.

In the app, you can monitor environmental factors, check the level of cat litter in the box, adjust the cleaning plan depending on your cats, and more. You can also generate daily reports to monitor your cat's weight and average toilet duration to catch any potential health issues.

The PETKIT Pura X is a self-cleaning litter box that's ideal for different size cats. You can expect to clean the waste tray out every week or so, although the manufacturers claim it can self-clean for up to 10 days. But, unlike some other robot litter boxes, this one really does keep odors at bay with its smart deodorizer spray. So, if by chance you forget to empty the tray, you're not going to be walking into a smelly room.

Using 12 built-in sensors, the PETKIT Pura X can identify when a cat is nearby and will activate thermal, infrared, weight, and anti-pinch sensors to protect your cats. Once your cat is inside doing its business, the app will notify you and keep you updated on your cat's toileting. While this might seem a little odd, it's actually incredibly useful, and can help you identify any potential health issues.

You can remotely control the PETKIT Pura X via the app and adjust the scheduled or automatic modes. However, you can also ditch the app if you don't want to use it and opt for the buttons next to the OLED display instead.

While the PETKIT Pura X mainly does what it's supposed to, there are a few quirks that knock it down a peg on the scoring board. Sometimes the litter capacity doesn't correctly register; you may need to fully empty the litter and fill it back up again just to top it up. Similarly, it can weigh your cat incorrectly if the right type of litter isn't used, or the right amount isn't in the box.
