Outsmart the litter box chore lr4
  • Litter-Robot simply requires 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.

  • We recommend up to 4 indoor cats per single Litter-Robot; however, we do have customers with more cats using a single unit. Litter-Robot 4 features an enlarged waste drawer for even more waste capacity, which means emptying is required less often.

  • If you and your cat are not completely satisfied, just return your Litter-Robot within 90 days of purchase for a full refund of the purchase price.

  • No, Litter-Robot does not have a weight limit. Size and weight often have little to do with whether a cat will adopt Litter-Robot or not. Whether or not Litter-Robot will be comfortable for a large or fat cat is up to the individual.

  • With Litter-Robot 3, once every 10-12 days per one cat is usually sufficient; two cats, twice per week; three cats, every other day. Litter-Robot 4 has an enlarged waste drawer, so you may not need to empty the waste drawer as frequently.

We change our filter every time we change the litter and they come out moldy sometimes. This is every 3 to 4 weeks. They help hold the smell pretty well.

After having some issues with one my LR4 globes, I started cutting these in half. I use half in the filter cage and in the other half I place a Fresh Breeze packet. This works great! I have 2 LR4s, 6 cats, and this combo keeps the globe free for rotating and smells great as it cleans.

I didn't know this was in the litter robot till Amazon suggested it. The robot started to smell more often and I didn't know why. Replaced the filter after 8 months and it does help the smell. The litter robot has such low maintenance this is easy to take care of.

I sort of set and forget my Litter Robot. About a year after purchasing it, I remembered… Hey! There’s a filter in this thing. It was disgusting. Do yourself a favor and order some spares to keep on hand.
