Lr4 Black Cat 1 Trimmed Compressed, The Cat 24

Read Our Full Brand Review

After hours of testing most of the leading self-cleaning units on the market, we recommend the Litter-Robot 4 as the best self-cleaning litter box you can buy.

The result of over 22 years of automatic litter box innovation, the Litter-Robot 4 is a well-designed, robust automatic litter box that uses a rotating mechanism to separate clean from dirty litter so you don’t have to.

It stands out from other automatic litter boxes with consistent, thorough cleaning, an advanced app interface with powerful sensor integration, and easy maintenance.

Paired with the Whisker app, the Litter-Robot 4 gives you powerful insights into and control over the unit’s performance.

You’ll know how much litter is in the litter bed and in the waste drawer, receive notifications when the drawer is full, and be able to trigger cycles remotely. And in contrast to the older Litter-Robot 3, the LR4 gives you detailed weight readouts.

This means that not only can you monitor your cat’s litter box activity, but you can also track which cat is using the box in a multi-cat home. Considering that automatic litter boxes, by nature, disconnect you from what’s happening in the litter box, this is an invaluable feature.

What We Liked:

  • Can be used with any clumping cat litter
  • Robust and highly durable design
  • Controls litter scatter fairly well
  • Reliable, automatic self-cleaning performance
  • Pairs with a powerful app that gives you plenty of insights

What We Didn’t Like:

  • Larger cats may find it too small and cramped
  • Very expensive, priced around $650
