FAQ

Which Litter-Robot is best for you depends on various factors such as number of cats in your household, price point, and desired monitoring capabilities.

• With over 13,000 reviews, Litter-Robot 4 is the trusted, time-tested choice—reliable and well-loved by longtime users.
• Litter-Robot EVO is the best beginner-friendly option as the most compact self-cleaning litter box model, ideal for smaller spaces and 1-cat households.
• Litter-Robot 5 is the latest and greatest design, offering a sleek and modern upgrade with features like WasteID, which identifies urine vs. feces to enable more targeted odour control and advanced routine monitoring.

No matter which Litter-Robot model you choose, you’re getting a thoughtfully designed, high-quality product that allows you to stop scooping the litter box and provides your cat with a fresh bed of litter for every use. Compare all Litter-Robot models here.

While Litter-Robot 4 is a tried-and-true option with 10,000+ 5-star reviews, Litter-Robot 5 builds on the same technology and features that make Litter-Robot 4 a success. In addition to SmartScale weight ID and litter- and waste-level sensing, Litter-Robot 5 offers advanced odour control with WasteID, a slightly larger interior globe space and waste drawer (for less frequent emptying), a brilliant LCD display screen, an expanded cat weight range of 1.36-13.6 kg, and accommodations for up to 5 cats. For a more in-depth look at the two models and what really changed, consult our dedicated Litter-Robot 4 vs 5 article or compare all Litter-Robot models in detail with our comparison chart.

Litter-Robot EVO is a more compact, streamlined version of Litter-Robot 4. It’s ideal for households with one to two cats, offered at a lower price point, and comes with fewer built-in app insights. Litter-Robot 4 is suitable for up to four cats, offers more advanced features such as litter- and waste-level sensing, and can be equipped with premium accessories like the LitterHopper.

The best litter for Litter-Robot is clumping litter. We recommend a high-quality, standard-weight, clay-based clumping litter. Some silica gel litter beads and crystals can also be used with Litter-Robot, as long as they pass through the screen. However, translucent or white-coloured litter (most often seen in crystal litter) may impact the litter level and Drawer Full Indicator (DFI) accuracy and are therefore not recommended. Alternative, plant-based litters typically do not work with Litter-Robot as these may not be filtered properly through the sifting system. Litters that do not work in Litter-Robot are the strictly absorbent, non-clumping or loose-clumping litters, newspaper-based litters, and absorbent wood pellet litter.

No, Litter-Robot does not require special bags or liners for the waste drawer. As long as it fits, you can use it. Customers often use 38-49 litre kitchen garbage bags or large plastic grocery bags. If you're looking for a no-fuss option, check out our custom-fit waste drawer liners in various size packs (five come free with each Litter-Robot). Our waste drawer liners work for any Litter-Robot model.

Yes. Kittens that weigh 1.36-13.6 kg or more can safely use Litter-Robot 5, Litter-Robot 4, and Litter-Robot EVO in automatic mode. (In older models like Litter-Robot 3, kittens must weigh at least 2.27 kg.) If your kitten does not meet this minimum weight, leave Litter-Robot off to operate in “semi-automatic” mode. When you see your kitten has used Litter-Robot, turn it on, and press the Cycle button to perform a clean cycle. Once it finishes, turn the power off. This way, your kitten is safe while they get accustomed to Litter-Robot at a young age, and you don’t have to scoop the litter box!

That depends on the model. Litter-Robot 5 works for up to 5 cats; Litter-Robot 4 works for up to 4 cats; and Litter-Robot EVO works for up to 2 cats. Litter-Robot 5 features an enlarged waste drawer for even more waste capacity, which means emptying is required less often. Litter-Robot cycles 7 minutes after each use by default, but if the wait time is interrupted by another cat entering, the timer will reset for another 7 minutes, which could cause waste to be present in the litter for longer than 7 minutes. Too many cats per single Litter-Robot may result in the litter bed not being clean for the next use.

Just for cases like this, we have compiled a list of tips and tricks to help your cat make the switch to Litter-Robot. If you have tried these things and your cat still refuses to use Litter-Robot, don't worry; you are protected by our 90-day in-home trial. If you and your cat are not completely satisfied for any reason, just return your Litter-Robot within 90 days of receipt for a refund of the purchase price, less shipping. You are responsible for return shipping costs. We can provide a return shipping label for a deduction from your refund.

Yes, all Litter-Robot models can accommodate large cats. With an entryway width of 40 cm and an interior height of 44.5 cm, Litter-Robot 5 is the best litter box for large cat breeds. Size and weight often have little to do with whether a cat will acclimate to Litter-Robot; the cat should be able to enter the globe and turn around inside it comfortably. Our weight limit recommendations are as follows: Litter-Robot 5: 1.4–13.6 kg; Litter-Robot 4: 1.4–11.3 kg; and Litter-Robot EVO: 1.4–8.6 kg.

Yes, Litter-Robot 5 and Litter-Robot EVO can be placed on any type of flooring due to their integrated carpet tray. If you plan to use Litter-Robot 4 on carpet or uneven flooring, you can improve the accuracy of SmartScale weight readings by purchasing our specially designed Carpet Tray that sits between the unit and the floor. (The Carpet Tray is not required for Litter-Robot 4 to function.)

Yes, compared to a traditional litter box, Litter-Robot can be an amazing litter box for messy cats, especially if they spray or aim high when they go. Both the globe and liner were designed to handle this, as the flange (rim) of the top half of the globe hangs over the bottom half of the globe, and the liner is made of a tough, impermeable flexible material. If any liquid gets above the halfway mark (above the globe liner), it simply drips or drains down to the liner and then into the litter without collecting or pooling anywhere. This results in a clump forming at the perimeter of the litter bed, which is removed by the peeling action of the globe liner during a clean cycle. Litter-Robot also ships with a preinstalled fence that helps prevent urine from dripping into the base. Constant spraying will require that you clean the interior of the globe more frequently to remove any residue, and, for deep cleaning, you can disassemble the globe into two halves (top and bottom). We recommend using the Litter-Robot Shield to further improve cleanliness. (Litter-Robot 5 Shield coming soon.)

Starting out, we recommend placing your Litter-Robot near your cat's old litter box to get your cat used to its new automatic litter box. As soon as your cat starts using their self-cleaning litter box regularly, remove the old litter box. At this point, the placement is up to you but we suggest avoiding the bathroom since the moisture can damage Litter-Robot's components. If possible, we recommend placing Litter-Robot on a firm surface and about an inch away from the wall. Litter-Robot 5 and Litter-Robot EVO can be placed on any type of flooring. If you plan to use Litter-Robot 4 on carpet or uneven flooring, please purchase our Carpet Tray accessory.

Because waste is promptly removed and contained in the base, typical litter box odours will be significantly reduced with Litter-Robot. Litter-Robot features a sealed waste drawer and Carbon Filter to reduce odours. You can opt to combine the Carbon Filter with OdorTrap Packs to eliminate litter box odours through natural chemistry. Litter-Robot 5 features additional targeted odour control with WasteID technology, which detects what type of bathroom visit occurred and when to cycle: for urine, it waits to let clumps form; for solid waste, it cycles quickly for targeted odour management. We also recommend using an unscented, all-natural litter to help with odour control. Even with advanced odour control, nothing can beat a regular cleaning routine. Be sure to perform a basic globe cleaning every 1-3 months and a deep cleaning at least every 3 months for optimal performance.

Yes. Because Litter-Robot automatically cleans after each use, your cat is not walking through dirty litter that can stick to their paws and be tracked out of the litter box. That said, the type of cat litter you use can make a difference in general litter tracking. Litter-Robot comes standard with a step and removable fence to reduce litter tracking out of the globe. You can purchase the Litter-Robot 4 Shield to further decrease tracking. (Litter-Robot 5 Shield coming soon.)

Litter-Robot comes with a power supply that plugs directly into the wall. We have a Litter-Robot 3 backup battery kit and Litter-Robot 4/5/EVO backup battery kit available on our website, which provides 24-48 hours of reserve power and are rechargeable so your Litter-Robot will remain operational in the event of a power outage. (Battery life varies depending on your cat's usage. The backup battery is not compatible with the Litter-Robot 4 LitterHopper.)

Litter-Robot may only need to be emptied once every 10 days, depending on the model and how many cats you have. Litter-Robot 5 features an extra large waste drawer that may only need to be emptied once every 10 days in a one-cat household. Litter-Robot 4 features a similarly large waste drawer that may only need to be emptied once every 8 days in a one-cat household; and Litter-Robot EVO will typically need to be emptied once per week in a one-cat household. The exact frequency depends on the number and size of your cats, as well as their litter habits. To help you stay on top of it, Litter-Robot will notify you when the waste drawer is full.

If the globe jams or an excessive load condition occurs, the motor is turned off automatically. In addition, all Litter-Robots are equipped with an anti-obstruction safety mechanism, meaning the globe will not turn while your cat is inside. Litter-Robot 5, 4, and EVO use weight sensors and anti-obstruction technology to detect when a cat has entered, so it knows when to cycle and when to wait. Litter-Robot 4 and Litter-Robot 5 also use integrated laser sensors.

If your cat enters Litter-Robot during a cleaning cycle, weight sensor technology will detect your cat and the globe will stop immediately. The cycle will not resume until 30 seconds after the cat is no longer detected. If your cat or something else is still tripping the sensor, Litter-Robot will not resume the cleaning cycle and the control panel or Whisker app will indicate the problem. The Support Center will help you troubleshoot common problems and our Customer Experience team is here to help when you need it.

Replace the Waste Drawer Liner whenever you need to empty the waste drawer. For optimal odour absorption, we recommend replacing the Carbon Filter and OdorTrap Packs every 2-4 weeks, but replacement frequency is up to you and your cats' usage patterns.

Cleaning the Litter-Robot exterior is easy. Just remove the globe and the drawer and use a mild cleaning agent such as our Cleaner Spray or Cleaner Wipes. You can also give them a sponge bath with mild soap and water, or take them outside for deep-cleaning with the garden hose. All other surfaces can be wiped clean, but should not be submerged. CAUTION: The base and bonnet of the Litter-Robot contain electrical components that should not be submerged.

We recommend cleaning Litter-Robot every 1 to 3 months, although this depends on your personal preference and your cat’s behavior. Learn how to clean your Litter-Robot:
1. For Litter-Robot 4 and Litter-Robot 5, press the Empty button to start an Empty cycle; for Litter-Robot EVO, press the Cycle button for 3 seconds. The Empty cycle causes the globe to cycle clockwise, which will allow the litter to fall through the waste port and into the drawer for easy disposal. Sweep any leftover litter toward the waste port. Then, press any button to return the globe to the Home position. Ensure that all litter has been removed from the globe—wet litter turns into messy clay!
2. Turn the Litter-Robot off and unplug the unit.
3. Remove the bonnet: Press and release the snap tabs on both sides of the bonnet, then lift and rotate the bonnet off of the globe and carefully set it aside.
4. Remove the globe: With two hands, lift the globe off the base.
5. Clean the globe with Cleaner Spray or with water and a mild soap. There are no electronic components in the globe that can be damaged by soap and water. If the globe has become extremely dirty, it can be soaked and cleaned with a water hose.
6. Let the globe dry completely before reassembling it to the base and attaching the bonnet. For a quick touchup, you can use Cleaner Wipes to wipe the inside and upper half of the globe (without removing the litter). Learn more about deep-cleaning your Litter-Robot.

The Cycle Delay is the elapsed time starting from when your cat exits the globe until the unit starts a Clean cycle. It can be set for 3, 7, 15, 25, or 30 minutes. The default Cycle Delay is 7 minutes. Reduce the Cycle Delay if it is important to minimize odour and/or the time that waste is available to other pets—such as dogs. However, reducing the Cycle Delay may reduce the cleaning effectiveness if clumps do not have enough time to set up. If urine clumps are sticking to the liner, perform a deep cleaning and extend the Cycle Delay to give the clumps more time to form

Litter Robot might not be cycling if the waste drawer is full, sleep mode is enabled, excess weight is detected, the litter level is too high, the cat sensor is dirty or malfunctioning, the unit is not on a level surface or placement is incorrect, or there is a mechanical issue with the motor or gear mechanism. Visit our Litter-Robot not cycling support article to learn more.
