  2. Can you use arm and hammer hardball litter?
    Hi Mike, great question! We don't recommend lightweight litter in the Litter-Robot as it can interfere with the weight-sensitive cat sensor.

  3. Can you use any litter with this? I know you recommend the clay and your brand, but I want to know the truth if I can use my current litter , which is Dr esley’s litter, or will it mess up and not work correctly?
    Hi Reese, great question. For best results, we do recommend a standard-weight clay-clumping litter. We do have many pet parents who use and love Dr Elsey's litter, too! You can use this in the Litter-Robot.

  4. Why do you make it SO difficult to find the dimensions/capacity of the actual litter tray? I've been able to find them maybe twice, after quite a while of searching, meanwhile you have no problem pointing out that the size has changed from the 3 to the 4. It's not "bigger", just different, because from what I've seen some of the measurements increased and others decreased. I can never understand why it's so SHALLOW yet expected to work for 3-4 cats for a whole week. The LR3 literally couldn't keep up with my one cat and I had to stop using it. I thought the 4 would be deeper but it doesn't appear that way, even though the bags you sell make it seem like it should be twice as deep at minimum. When will you make the bin deep enough so it's actually easier than using a regular litter box? I'm extremely disappointed by how you claim it uses less litter and you don't have to bend down as often, because it's simply not true.
    Hi there, we're sorry if you had trouble locating dimensions for our Litter-Robots. If you visit the Support Center section of our website here: www.litter-robot.com/support, you can view the Quick-Start guides or user manuals for any of our machines, which do include dimensions.

  5. I use pellets. Can I still use this?
    Hi Mia, great question! Pellet or Tofu Litter will not work in our units at this time. We tend to find the best results from an unscented, standard-weight clay clumping litter.

  6. Can you use tofu pellet litter with the newest model?
    Hello Lindsay! Pellet or Tofu Litter will not work in our units at this time. We tend to find the best results from an unscented, standard-weight clay clumping litter. Our GreatLitter® is low dust and low tracking! You can check it out here: www.litter-robot.com/litterbox-com-all-natural-clumping-litter.html

  7. How often would you be adding fresh cat litter to the Litter robot 4 if you have 2 or 3 cats approximately?
    Hello Nancy, great question! Litter-Robot uses litter efficiently since the patented sifting system only removes the clumps. We recommend checking the litter level against the raised fill line each time you empty the waste drawer, which is about once per week for a single cat or twice for multiple cats.

  8. When I clean out the waste bin.....and push the button to make our model 4 recycle - the report on our phones tells us that the waste is 20% full....when I just emptied it!! Is there a way I can recalibrate that reader to make it more accurate?
    Hello Rebel; yes! You can find the steps to calibrate your Drawer Full Indicator here: https://whisker.elevio.help/en/articles/111-litter-robot-4-calibrating-the-drawer-full-indicator
