摘要： A power sweeper has a handle having a first end graspable by a user and a second end, a drive shaft extending along the handle, and a power head coupled to the handle to rotate the drive shaft. A gear box is coupled to the drive shaft adjacent the second end, and a brush is coupled to the gear box for rotation in response to rotation of the drive shaft. The power sweeper includes an axle, and first and second wheels coupled to the axle. A shield is coupled to the gear box and defines an aperture through which the handle extends. The axle is moveable with respect to the shield and the brush to adjust an angle between the handle and the ground surface.

摘要： A handheld floor sweeper having a debris receiving compartment in the sweeper body having a bottom tray that is pivotally connected to the sweeper body. A latching mechanism that is operated by the user pushing a release lever allows the bottom tray to pivot to an open position to discharge debris collected in the compartment without the user having to contact the debris. The tray is pushed back to the closed position by the user after the debris is discharged where the tray is once again latched in the closed position.

摘要： A pivoting and swiveling floor treatment appliance includes a lock-prevention member that prevents a body from becoming pivotally locked in a forward/backward direction when a portion of the body is in a swiveled position. The lock-prevention member may move relative to an appliance head and to a portion of the body that swivels. In some embodiments, components of the lock-prevention member contribute to locking the swivel of the body when the body is pivotally locked.

摘要： A liquid extraction cleaning device comprises a vacuum pump, a liquid pump, a cleaning solution tank, a recovery tank, first and second spray nozzles, a spray selection switch, a vacuum inlet port, an agitator assembly, and a handle. The spray selection switch controls whether liquid is expelled from the second spray nozzle when liquid is expelled from the first spray nozzle. The agitator assembly comprises first and second agitators. The first agitator is configured to rotate. The second agitator is configured to reciprocate. The handle is pivotally connected to the rest of the liquid extraction cleaning device and is lockable in several pivotal orientations. The handle can also be pivoted forward from a rearwardly extending direction to an extent that it extends forward horizontally.

摘要： A surface cleaning apparatus has a main body having a main body actuator operable between an open position and a closed position. An assembly removably mounted to the main body has an air treatment member having an openable door and an assembly door lock, the assembly door lock comprising an actuation portion operable between an open position and a closed position and lock portion operable between an engaged position in which the door is secured in a closed position and a disengaged position in which the door is openable. When the assembly is mounted to the main body, the main body actuator is operatively connected to the actuation portion of the assembly door lock whereby when the main body actuator is moved from the closed position to the open position, the actuation portion is moved.
