How to change the CR1-4 litter tray
Watch the guide or follow the steps.
- 1When the tray light stays solid red, or the app shows the tray as Expired, unplug the box, lift the main unit and take out the used tray.
- 2Put the used tray in a bin bag and throw it away.
- 3Wipe the waste trap lid, rake and main unit with a damp tissue.
- 4Fit the new tray with its identification sticker on the same side as the camera, pour the crystal litter in evenly and lower the main unit.
