  2. How many years on average will the robot 4 last?
    Hi Maw. We can't guarantee a specific timeframe, as longevity depends on various factors, such as the environment, amount of use, and overall upkeep. Rest assured, we're always here to troubleshoot and provide support even after your WhiskerCare warranty has expired!

  3. Hello I have a large cat.He is 32 inches from nose to tail.And I'm wondering which of these would work best for him? All of my other cats are normal size
    Hi Forest. It really depends on your kitty - we have many pet parents with large (25+ lb.) cats who use the Litter-Robot 3 and 4 with no trouble. We also offer our 90-day in-home trial which allows you time to really make sure your kitty is comfortable, and you can return the unit if they're not.

  4. There is a thin filled strip on the inside that has come loose and prevents the drum from turning. Do you have a replacement part or will it run without the strip?
    Hello Luce, this is a great question! We do carry replacement seal strips for your Robot: www.litter-robot.com/litter-robot-4-seal-strips.html. The unit can work if they're missing, but it can cause some residual odor issues. If you're under warranty, contact us support@whisker.com for assistance.

    Hi Melissa! The Litter-Robot 4 does not have an upper-weight limit. We've got many users with 25+ lb. cats who use the Robot with no issue.

  8. Cat house x4. One LR4 claims to be good for up to 4 cats. How often will the drawer/ trash unit need to be emptied with 4 smaller to average size cats?
    Hi there! It depends on the cats, but generally speaking, you can expect to empty the waste drawer once every 7-10 days with one cat, twice per week with two cats, every other day with three, and daily with four cats.

  9. Is the inside stainless steel
    Hi there. The interior of the Litter-Robot 4 is not stainless steel. The globe liner is made from TPE, which is a thermoplastic elastomer material with the high elasticity, strength and resilience of rubber. TPE material does not contain plasticizer and is an environmentally friendly non-toxic material.
