Abstract
A cleaner for cleaning a surface comprises a floor-engaging portion for moving along the surface. A magnet and a hall effect sensor located in the cleaner handle generates a control signal. The control signal is provided to a control circuit which controls one or more operational features of the cleaner. One such operational features includes at least one pump for mixing and distributing cleaning solution to the surface. In an alternate embodiment, the control circuit controls an electric motor for propelling the cleaner over the surface.
