1. Pure Clean Smart Robot Cleaning Vacuum – Best Overall

Pure Clean Smart Robot Cleaning Vacuum (1)

 Dimensions:   19.09 x 15.08 x 4.92 inches
 Weight:   11.52 pounds
 Material:   Plastic

The Pure Clean Smart Robot is indeed quite smart, as it can handle most messy tasks without your supervision! Indeed, this little gem of technology is equipped with sensors that allow it to avoid obstacles and falls, allowing you to wander about your business while it cleans the dirt left by your cat. Furthermore, a remote control is included so you can start cleaning even when you are away from the house. In addition, it works on several types of surfaces, such as hardwood, tile, marble, or hard carpet floors. All of these features make this little robot vacuum the best overall option we’ve found.

The only catch is that it seems to have a hard time getting back to the charger on its own, although it doesn’t happen all the time.


  • Anti-collision sensors
  • Very easy to use
  • Includes remote control
  • Very quiet
  • Built-in rechargeable battery
  • Works on any surface


  • Does not go back to the charger by itself

2. Eufy RoboVac 11S Robot Vacuum Cleaner – Best Value

Eufy RoboVac 11S Robot Vacuum Cleaner (1)

 Dimensions:   12.8 x 12.8 x 2.85 inches
 Weight:   5.73 pounds
 Material:   Plastic

Eufy RoboVac 11S is a small, quiet, easy-to-use robot vacuum cleaner that offers excellent value for money. It sucks up litter debris and other dirt from your home very effectively but can have a bit more difficulty with substantial debris. This small, compact model is perfect for cleaning those corners that are more difficult to access but strangely tends to bump into dark objects. It finds its way to its dock about half the time, so you may find it dead in a corner of your house from time to time. Nevertheless, it has enough advantages to justify its purchase, especially with regard to its affordable price.


  • Very easy to use
  • Runtime up to 100 minutes
  • Super quiet
  • Strong suction power
  • Affordable


  • Can bump into dark color items
  • Not very efficient in picking heavy dirt

 3. iRobot Roomba i3+ 3550 Auto Charging Robotic Vacuum – Premium Choice

iRobot Roomba i3+ 3550 Auto Charging Robotic Vacuum (1)

 Dimensions:   13.34 x 13.26 x 3.63 inches
 Weight:   15 pounds
 Material:   Plastic

The iRobot Roomba does a fantastic job cleaning up the mess after your cats. Its smart navigation and ease of use are among its best features. Plus, after every cleaning, it empties into a trash bag that takes up to 60 days to fill, so you can forget to vacuum for months. The machine will also automatically return to its docking station to recharge when the battery is low. Plus, it’s perfect for cat owners because it comes with a HEPA filter to suck up allergens while it cleans up after your pet. But despite all these amazing features, it’s not perfect. Its noise level is above average, it is a bulky model, and its docking station will take up a lot of space in your living room.


  • Amazing suction power
  • Empties itself for 60 days
  • Runtime is up to 75 minutes
  • Has personalized cleaning suggestions
  • Ideal for sweeping corners


  • Takes 6 hours to charge fully
  • Very expensive
  • Noisy

 4. SereneLife Smart Robot Vacuum Cleaner – Best for Kittens

SereneLife Smart Robot Vacuum Cleaner (1)

 Dimensions:   11.4 x 11.4 x 2.75 inches
 Weight:   8.73 pounds
 Material:   Plastic

This tiny robot vacuum is perfect for cleaning up after kittens or if you live in a small apartment without too many obstacles. It does include anti-fall sensors like most robot vacuums, but you may need to watch it a bit more as it tends to get stuck. However, it is easy to use, includes a remote control, and effectively cleans litter debris, hair, and other dirt. However, if you live in a big house with many stairs or have large cats, this option may not be for you.


  • Includes a remote control
  • Can fit under most furniture
  • Easy to use


  • Lasts only 60 minutes between each battery charge
  • Works better on tiny rooms

5. ILIFE V3s Pro Robot Vacuum Cleaner

ILIFE V3s Pro Robot Vacuum Cleaner (1)

 Dimensions:   11.8 x 11.8 x 3 inches
 Weight:   4.5 pounds
 Material:   Plastic

ILIFE V3s Pro robot vacuum is another lightweight option with a slim design that allows it to venture into the dark corners of your home. It’s independent enough to get back to its charger by itself, but you’ll need to watch it as it sometimes gets stuck in some places despite its sensors. Some users compare it to a two-year-old helping you clean up: he starts out on his own, encounters a problem, asks for your help, gets back on track, and a few minutes later asks for your help again. Nevertheless, this robot vacuum cleaner has an exciting function, that of being able to “defend” against the attacks of an overly curious dog or cat! This self-protection function is automatically programmed into the device and is very useful in homes with young crazy animals!


  • Runtime up to 100 mins
  • Automatically docks and recharges
  • Can “defend” itself against dog attack
  • Includes remote control


  • Not the best option for deep cleaning
  • Gets stuck a lot
  • Takes 6 hours to recharge fully

6. Roborock E4 Robot Vacuum and Mop Cleaner

Roborock E4 Robot Vacuum and Mop Cleaner (1)

 Dimensions:   19.37 x 16.1 x 6.18 inches
 Weight:   7.94 pounds

With such a name, it’s normal to expect this robot vacuum to do wonders in your home! Roborock E4 indeed fulfills its mandate very well, and it will easily get rid of all the cat litter spilled by your furry friend. Plus, its autonomy can reach 200 minutes, double the average of other robot vacuum cleaners. It does, however, require a little supervision because it can get stuck in certain places, like many other robots.  Nevertheless, given its relatively high price, one should expect a little more autonomy. However, it usually has no problem coming back to the dock on its own and getting the job done. It is, however, a little noisier than the other models, which could frighten more sensitive kitties!


  • Runtime up to 200 minutes
  • Washable filter
  • Great suction power
  • Automatic top-up charging


  • Expensive
  • Not suitable for high-pile carpet and dark-colored floors
  • A bit noisy

Its compact design and lightweight is ideal for small spaces; it also has good battery life, up to 100 minutes after a full charge. However, it sometimes has trouble following the cleaning patterns correctly, which can become frustrating in the long run. Additionally, some users have reported that it gets stuck on some furniture.


  • Runtime up to 100 minutes
  • Very quiet
  • Voice control available


  • Struggle to follow patterns of cleanings

Buyer’s Guide

The best cat litter vacuum is one that meets all your needs, including type, wattage, capacity, run time, noise level, size and weight, warranty, and any additional features. The features below will help you choose the robot vacuum that best suits your needs.


The type of vacuum can make a huge difference in your cleaning, whether it’s an upright vacuum, a cordless hand vacuum, a stick vacuum, or a robotic vacuum. Upright vacuums are suitable for most homes, although they require more manual labor, while robot vacuums are designed to be adjusted and left in place, which is ideal for people who don’t want to spend a lot of time cleaning.

For example, a hand vacuum may be the best solution if you want to clean the cat litter box quickly. Nonetheless, robot vacuums offer more convenience and autonomy, although they are generally priced higher than other options.


The power level may vary depending on the type of vacuum cleaner. Upright vacuums tend to be more potent than robots or hand vacuums, for example, as they are most often used for cleaning the whole house. And since power is related to suction, it’s important to choose a vacuum that can meet your needs. For example, if you live in a house where there are a lot of pets, you may want to look for a robot vacuum with a high-power level.


All vacuum cleaners, regardless of their type, have a capacity. For example, robot vacuums do not have bags but a plastic tank to be emptied regularly. Indeed, every model on our list is bagless, which means they use tanks, and at some point, the vacuum will be full of dirt and debris and will need to be emptied. The larger the tank, the more dirt and debris the robot vacuum can hold before it needs to be emptied.

If you’re interested in buying a robot vacuum, know these models usually run on a rechargeable battery system, which is especially useful when looking for a vacuum for a quick cleanup of cat litter or pet hair. The duration of use is, therefore, an essential element to consider when buying a robot vacuum cleaner.

Noise Level

Vacuuming can be noisy. The suction creates a noise that cannot usually be avoided. But if the noise level is an important factor for you, especially if you have a household with sensitive kitties who might be scared off by standard vacuum cleaners, it will be a good idea to turn to robot vacuums. Because since they’re designed to vacuum on their own, they’re also designed to be as unobtrusive as possible, which means they’re generally quiet and won’t disturb you or your pets.

Dimensions and Weight

The size of the vacuum cleaner is one of the most important aspects to consider when purchasing it, regardless of its type. If a hand vacuum is too heavy, battery life won’t matter if you can’t carry it long enough to get the job done. If a robotic vacuum cleaner is too large, it will not be able to go under your furniture to clean it. And if your upright vacuum is too heavy, it can be difficult to use in your rooms, and if it’s too large, it can be difficult to store.


It is always important to check the warranty of any vacuum cleaner you purchase. A well-made robot vacuum should last for years, but sometimes an accident happens, and you have to rely on the warranty for replacements or repairs.

Bonus Tip

Robot vacuums are handy for regular floor cleaning, but they are not suitable for quick cleaning of heavily soiled floors, such as flour or spilled crumbs on the floor. For these emergencies, a conventional vacuum cleaner will be much more efficient.


Robot vacuums are perfect for cat owners who want to do without the chore of vacuuming. Indeed, robots have a “set-it-and-forget-it” mentality when it comes to vacuuming. If you are looking for an affordable option with excellent features for picking up litter box messes left by your beloved cat, the Pure Clean Smart Robot Vacuum is an ideal model. If you are on a tighter budget but still looking for good value for money, the Eufy RoboVac 11S will suit you better. And if you’re in the mood to splurge and noise level isn’t a big deal in your purchase, the iRobot Roomba will have you covered.
