Litter-Robot II Basic Troubleshooting Guide

For those who have been enjoying the Litter Robot automatic self cleaning litter box for a few months or a few years, you know that this is a great product that has very few issues. But, it is a robot with sensors etc. that can fail with usage. We do have tricks and things to verify for basic issues if the robot goes into error and wanted to share them with our readers. In many cases, just a verification and adjustment of sensors can fix the Litter-Robot without having to repair it.

We suggest verifying the following: 1. While the globe is at the dump position please check to see if the waste port guard handle is interfering with the entrance lip of the flexible liner.

If this appears to be the case like in the picture above then please re-position the lip such that the channel at the base of the lip is fitted onto the hard plastic opening. If you have a lip extender, please also make sure it is properly installed under the arm such as the arm moves freely up and down.

2. Remove the globe and make sure there is nothing stuck on the base where the globe turns. Make sure there is nothing preventing the globe from turning properly. Please also make sure the litter-robot is on a level surface.

3. Please check the control panel for any evidence of urine residue. Also, if you see urine in the bottom of the waste drawer, this would be an indication that your cat is missing the litter and urinating just outside the opening, which may be damaging the circuit board behind the control panel.

You will then be able to visually verify the circuit board for evidence of urine. If this is the case, a new circuit board would be recommended. 4. Let's also make certain the cat sensor is at the factory setting. Please remove the globe and waste drawer and make certain the unit is off.

If you do not, then adjust the cat sensor by turning what we call the foot/knob that is directly underneath the base until it is. Depending on the size of your cat, you may need to adjust it slightly.

Put everything back together and let the unit cycle. In many cases, most problems should have been fixed by verifying the switches.
