The 2 B’s on the Litter-Robot have the electronics on them, being Bonnet and Base. These items are cleaned with a damp cloth, so the electronics do not get wet.
Generally a wipe down is all that is needed, but there is some wear that occurs, and for the bonnet, this is usually the connectors.
Metal strips, located in the left side (facing the Robot) of the bonnet, these little bendy bits stick out from the bonnet to make good contact with the base silver strips, completing the power circuit.
They do need to be wiped from time to time, to keep them clean of debris. They also need to be inspected for signs of corrosion, and wear, as if the connection is not sufficient, the Robot may had cycling issues. Typically, this will be a slow yellow flash (1 per second), that even with the bonnet well fitted (rear tabs in and front tabs secured well so if you try to lift with the finger holes, the bonnet stays on), cycling maybe interrupted.
A quick clean with some light grade sandpaper may help.
However, if you need to replace the strips, its very simple. Contact email@example.com to order the replacement part.
When received, the strips are easy to fit, and you only need a phillips head screw driver.
The cover for the strips has 2 screws. Remove these. You can then see the silver strips and reddish plugs fitted to the ends.
Remove the strips from the slots, and gently pull the plugs off (hold the plug not the wires when pulling).
Replace with the new strips, refit to slots, screw on cover, and refit bonnet.
Its that simple.
