Abstract: A combination of a floor cleaner and a cleaning tray. At least a portion of a base of the floor cleaner is received by a reservoir of the cleaning tray. The floor cleaner further including an upright portion movable between an inclined use position and an upright storage position. The brushroll is powered by a brushroll motor. The brushroll motor includes a control circuit that controls the brushroll. The control circuit has a first switch that is open when the floor cleaner is in the upright position and closed when the floor cleaner is in the inclined use position. The second switch is in parallel with the first switch. The second switch is opened in response to the portion of the base being removed from the cleaning tray and the second switch is closed when the portion of the base is in the cleaning tray.

Abstract: A cleaning system comprising a vacuum source, a current sensor, a recovery tank having a shutoff float configured to float on a surface of fluid within the recovery tank, and a controller. The vacuum source is in fluid communication with a suction inlet via first and second air paths within the recovery tank. The shutoff float is further configured to block the first air path upon the fluid within the recovery tank reaching a desired level. The controller is configured to receive, from the current sensor, a signal indicative of the current drawn by the vacuum source. The controller is further configured to determine, based on the current drawn by the vacuum source crossing a threshold, the fluid within the recovery tank has reached the desired level and control an operating element of the cleaning system upon determining the fluid within the recovery tank has reached the desired level.
