Abstract: A surface cleaner (10) includes a housing (12) having a first tank guide projection (82) that is received in a first recess of a supply tank (14) when the supply tank is in a supply tank operating position and the first tank guide projection includes a cooling air inlet (85) in fluid communication with a cooling air inlet of a pump housing (72). The housing further includes a second tank guide projection (84) that is received in a second recess of the supply tank when the supply tank is in the supply tank operating position and the second tank guide projection forms a cooling air flow path between the cooling air inlet of the first tank guide and the cooling air inlet of the pump housing.

Abstract: A floor cleaner that includes a cleaning head, an agitator drive, and an agitator. The cleaning head includes an agitator chamber having an opening facing toward a surface to be cleaned. The agitator is rotatably disposed within the agitator chamber and positioned to contact the surface to be cleaned through the opening. The agitator extends longitudinally between a first end and a second end along an axis of rotation. The agitator includes a core operably connected to the agitator drive, rotatable about the axis and at least one molded agitating member integrally formed with the core. The agitating member extends from the core to contact the surface to be cleaned.

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.

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 floor cleaner includes a suction source, a body, and a rotary working element. The body includes a working element chamber having an opening facing toward a surface to be cleaned and a suction inlet in fluid communication with the suction source. The rotary working element is positioned within the working element chamber and includes a body rotatable about an axis having silicone features extending outwardly from the body to contact the surface to be cleaned though the opening.

Abstract: A floor cleaner including a recovery. The recovery tank is configured to contain a fluid drawn through a suction inlet from a surface to be cleaned by a vacuum source. The recovery tank includes a shutoff float. The shutoff float is movable between a first position and a second position. The shutoff float includes a float body, a float closure, and a first interconnecting member. The first interconnecting member engages a second interconnecting member to retain the float in the first position. In the first position, the shutoff float is spaced a distance from the suction air outlet, allowing air flow through the suction air outlet. The first interconnecting member engages the second interconnecting member to retain the shutoff float in the first position. In the second position, the shutoff float is adjacent the suction air outlet, inhibiting air flow through the suction air outlet.
