The Litter Robot is a self-cleaning litter box that can save you time and effort. It is designed to make your life easier and keep your cat’s box more sanitary. In this article, we will review the Litter Robot 4 and its features.

Litter Robot 4: Design and Specs

The Litter Robot 4 is a self-cleaning litter box that uses an auto-cycling globe to separate clean litter from waste and deposits clumps into a drawer below. It has an upgraded laser sensing system and an extra-large waste drawer with odor-locking technology.

The third-generation machine can recognize cats weighing 5 pounds or more, but the Litter-Robot 4’s laser sensing system can recognize cats weighing at least 3 pounds. The larger, odor-reducing waste drawer requires less frequent emptying.

This box has a very quiet cycle of about 33 decibels (dB). It’s significantly quieter than the Litter-Robot 3 (48.7 dB) and our dust-free recommendation, CatGenie AI (51.4 dB).

A difference of 15 dB is significant when you live in a small space or if, like me, you plan to keep the litter box in a bedroom. With a footprint of 22 inches wide, 27 inches deep, and 29.5 inches high, the Litter-Robot 4 is slightly slimmer than the Litter-Robot 3.

Litter Robot 4 Review: Safety Features

The Litter-Robot 4 has the best safety features of the automatic litter boxes. It cycles quietly and is thoughtfully designed for cats of all sizes and needs, with a spacious interior for large cats and optional steps for mobility-impaired felines. Plus, its smart features can help you monitor your cat’s well-being.

Cleaning the Litter-Robot 4 is a straightforward process that can be done in a few simple steps. Here’s how you can do it:

  1. Press the Empty button to cycle the globe clockwise, which will allow the litter to fall through the waste port and into the waste drawer for easy disposal. Sweep any leftover litter toward the waste port. Then, press either Cycle or Reset to return the globe to the home position. Ensure that all litter has been removed from the globe.
  2. Turn the Litter-Robot OFF and unplug the unit.
  3. Open the Bonnet: Press and hold the buttons on both sides of the Bonnet, then lift and rotate the Bonnet to its open position.
  4. Remove the Globe: Using the handle, lift the Globe off the Base.
  5. Remove the Carbon Filter from under the globe.
  6. Clean the Globe with Litter-Robot Cleaner Spray or Cleaner Wipes, 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.
  7. Let the globe dry completely before reassembling it at the base and closing the bonnet.

You should do a basic globe cleaning every 1-3 months and a deep cleaning at least every 3 months, depending on how many kitties you have. More frequent deep cleanings may be necessary depending on use. For a deep cleaning, you can follow the instructions provided on the Litter-Robot website.


The Litter Robot 4 is the best overall self-cleaning box. Sure, a lot to spend on a litter box, but this machine gets the job done. It automatically disposes of cat waste, sparing you from having to see or smell it and keeping your cats from stepping in it later. It is also designed to be safe for your cats and has smart features to monitor their well-being. If you are looking for a self-cleaning litter box, the Litter-Robot 4 is worth the investment.
