Quick checks
Start here
Charge, filter, impeller, tracks: in that order. Where a check ends in a worn part, the genuine replacement is linked under it.
Use the charger supplied with the robot and charge indoors, out of direct sun.
Rinse the filter after each cycle and check the impeller grill for hair and debris.
Remove anything caught in the tracks; worn tracks are a cheap replacement part.
