    摘要： An accessory tool assembly (20) adapted to couple with a hose (40) of an extraction cleaner (22) including a suction source (52) includes a tool head (42) and at least one fluid distributor (34, 36) for supplying and directing a cleaning fluid therethrough. The tool head (42) includes a front end (128) and a rear end (122) opposed to the front end (128), wherein a longitudinal direction (126) extends through the front and rear ends (128, 122) and a transverse direction (134) extends perpendicular to the longitudinal direction (126). The tool head (42) includes a working surface (116) on an underside of the front end (128). A plurality of agitators (138) extend from the working surface (116) and define a first interior area (140) therewithin. An extraction nozzle (45) is positioned in the first interior area (140) and defines at least a portion of a suction air inlet (46).

    摘要： A handheld extraction cleaner (10) includes a unitary body (12) provided with a carry handle (14), and further provided with a supply tank (26), a suction nozzle (16), a recovery tank (20), and a suction source (18), all of which are carried by the unitary body (12). In one aspect, the recovery tank (20) is configured to optimize the usable volume within the tank and a user's view of the collected dirty liquid within the tank, among other functions. In another aspect the recovery tank (20) has an auto-close feature (194) that automatically seals an outlet (118) of the tank when the recovery tank (20) is mounted to a tank receiver (128) of the unitary body (12). In yet another aspect, the extraction cleaner has an agitator (38) that slides out from a side of the unitary body (12). In still another aspect, the suction nozzle (16) includes a cleaning angle guide skid (270) to orient the extraction cleaner at an optimal cleaning angle. In a further aspect, the supply tank (26) is a non-removable part located at a rear of the unitary body (12).

    摘要： A suction head (10) for an extraction cleaner (132) including a base (12) forming a suction chamber (16) and a suction outlet (26) in fluid communication with the suction chamber (16); and a piezoelectric element (14) coupled to the base (12), the piezoelectric element (14) comprising a first surface (40) open to the suction chamber (16), a second surface (42) facing an external environment (34) away from the suction chamber (16), a thickness (44) between the first surface (40) and the second surface (42), and a through-via (46) through the thickness (44) open at both the first surface (40) and the second surface (42). An extraction cleaner (132) including the suction head (10).

    摘要： A surface cleaning apparatus (10) includes a steam delivery system, a liquid delivery system, and a recovery system. The steam delivery system may include a steam dispenser (48) having one outlet (330) to dispense steam toward the surface to be cleaned and another outlet (332) to dispense steam away from the surface to be cleaned as visible steam vapor. The apparatus (10) may have multiple cleaning modes, including a mode where liquid is dispensed and a mode where liquid and steam are dispensed. Methods for operating a surface cleaning apparatus (10) and for self-cleaning a surface cleaning apparatus (10) are also provided.

    摘要： An electric marine propulsion system (2) configured to propel a marine vessel (1) includes a power storage system (16) comprising a plurality of batteries (18a-d) and at least one electric motor (4) powered by the power storage system (16) and configured to rotate a propulsor (10) to propel the marine vessel (1). A control system (11) is configured to identify a charge level (81a-d) for each of the plurality of batteries (18a-d) and determine which of the plurality of batteries (18a-d) are active batteries based at least in part on the charge level (81a-d) on each of the plurality of batteries (18a-d). A minimum power limit is then identified for the active batteries and a system power limit is determined based on the minimum power limit and the number of active batteries. The at least one electric motor (4) is then controlled based on the system power limit such that the system power limit is not exceeded.
