Narwal Freo S - Robot Vacuum & Mop

A satisfactory worker but is hindered by not being able to charge itself without having to put a sheet of cardboard over the carpet where the base station is located. I don’t believe this should be necessary and believe it may be a design issue unless it was designed to have the base station solely on a hard floor. This isn’t practical when cleaning upstairs when all areas are carpeted except the bathroom which cannot accommodate a base station.
