Abstract: A floor cleaner including a base movable over a surface to be cleaned, the base including a front side, a back side opposite the front side, and a brushroll chamber. A supply tank is configured to store a cleaning fluid and a distribution nozzle is in fluid communication with the supply tank, the distribution nozzle operable to dispense the cleaning fluid onto the surface to be cleaned. A brushroll cover is removable from the base to access the brushroll chamber. A brushroll is within the brushroll chamber. The distribution nozzle is disposed adjacent the front side of the base and carried on an upper exterior portion of the base and configured to spray forwardly of the base in a direction from the back side toward the front side.

Abstract: A floor cleaner including a recovery tank. The recovery tank includes a tank body having a lower end wall, an open upper end, and a sidewall that extend upwardly from the lower end wall. A cover that includes a suction air outlet in fluid communication with a vacuum source. An inlet duct extends upwardly from the lower end wall. The recover tank includes a shutoff float including a float body and a closure. The float body is configured to float on a surface of cleaning fluid and the closure is received in the suction air outlet to close the suction air outlet. The float body moves along the inlet duct as the float body floats on the surface of the cleaning fluid. The float body includes an aperture extending through the float body and the inlet duct extends through the aperture of the float body.

Abstract: A floor cleaner including a vacuum source recovery tank or collection bin and a body pivotally coupled to a base. The body is pivotable between an upright storage position and an inclined operating position and the body includes a recovery tank recess. The floor cleaner further includes a recovery tank removably coupled to the body in the recovery tank recess, the recovery tank in fluid communication with a vacuum source and a suction inlet, the recovery tank configured to store the cleaning fluid and/or debris drawn through the suction inlet from a surface by the vacuum source. The floor cleaner further includes a projection and a recess that receives the projection when the recovery tank is coupled to the body to limit movement of the body relative to the recovery tank.

Abstract: A floor cleaner including a vacuum source and a base movable over a surface to be cleaned. The base includes a suction inlet in fluid communication with the vacuum source, a brushroll chamber, a brushroll in the brushroll chamber, the brushroll rotatable about a brushroll axis, a brushroll cover releaseably attached to the base, the brushroll cover removable to access the brushroll chamber and the brushroll. The base further includes a first actuator movable in a first direction from a latched position and to an unlatched position and a second actuator movable in a second direction, opposite the first direction, from a latched position and an unlatched position. The brushroll cover is secured to the base when the first and second actuators are in the latched positions and the brushroll cover is removable from the base when the first and second actuators are in the unlatched positions.
