Apparatus and method for receiving and holding debris in a collection chamber of a vacuum cleaner. The collection chamber has an inlet opening through which debris-entrained air enters the collection chamber. When the vacuum cleaner is off, an internal valve prevents debris from leaving the collection chamber through the inlet opening. The internal valve is movable from a first sealed position, in which the internal valve covers the chamber inlet opening, to a second unsealed position in which the internal valve does not cover the chamber inlet opening.

A floor cleaning machine with a base, which has a driven cleaning element, and an operating bar that is pivotably attached to the base via a joint and extends between a proximal end and an actuating end. The joint includes a bellows, which is coupled at its opposite ends to the base and the operating bar, a first supporting element, which is arranged inside the bellows and is attached to and points away from the base, and a second supporting element, which is arranged inside the bellows and is attached to and points away from the proximal end of the operating bar. A free end of one of the first and second supporting elements has a projection, while a free end of the other of the first and second supporting elements has a receiving recess that receives the projection and guides it for pivoting movement.

A floor cleaning machine having a base, a suction foot, a dirty water tank in fluid communication with the suction foot, a suction turbine, and a separation container. The suction turbine is attached to the base and generates a suction air flow from the suction foot into the dirty water tank. The suction turbine has a housing with an inlet opening and an outlet opening through which air flows. The separation container adjoins the suction turbine housing and has an interior, which that communicates with the inlet opening and a bottom wall section that faces the interior. The bottom wall section is disposed vertically lower than the inlet opening. A drainage opening leads out of the bottom wall section into the environment and is provided with a valve that is closed during operation of the suction turbine is in operation and open when the suction turbine is not operated.

An ultrasonic cleaning tool for cleaning a surface has a transducer and a horn for generating and transmitting vibrations to a surface to be cleaned. Cleaning solution can be supplied to the ultrasonic cleaning tool or the surface to be cleaned, and operation of the ultrasonic cleaning tool can agitate the surface and cleaning solution. The tool can be provided as part of a system for cleaning a surface, and the system can include an extraction cleaner or a cleaning cloth.

The present disclosure discloses an automated cleaning robot which includes a robot body capable of realizing automatic walking and a mop mechanism provided at a rear end of the robot body. The mop mechanism includes a mount support rotatably connected to the robot body, a rotation component received in and rotatably connected to the mount support, a crawler-type wiping cloth sleeving outside the rotation component, and a lifting mechanism being in transmission connection with the mount support, for driving a rear end of the mount support to ascend or descend relative to a front end of the mount support.

The present disclosure discloses an automated floor cleaning apparatus, has an automatic cleaning robot and a washing base; the rear end of the robot body of the automatic cleaning robot is provided with a mop mechanism, the mop mechanism comprises a rotation component rotatably connected to the robot body and a crawler-type wiping cloth sleeving outside and rotating along with the rotation component. The invention provides can automatically and effectively removes dirt attached to the crawler-type wiping cloth, avoiding artificial detaching and then cleaning the wiping cloth stained with dirt, automatically performing washing operation, greatly alleviating operation burden of a user, and having a good floor sweeping effect.

A mopping mechanism is provided. The mopping mechanism includes at least one mopping plate movably mountable to a bottom surface of a cleaning device. The mopping mechanism also includes a magnetic element assembly including a primary magnetic element and a secondary magnetic element, and configured to generate a variable magnetic field to drive the at least one mopping plate to move reciprocatively relative to the bottom surface.

An apparatus for cleaning a floor includes a housing, chassis, wheels, motor, steering mechanism, cleaning assembly, optionally a squeegee assembly, and at least one of a side sweeping system, front sweeping system, and pick-up system. The side sweeping system includes a turntable with central axis, a drive wheel disposed in coaxial relationship with the turntable, a sweeper motive device in communication with the drive wheel, a plurality of brushes distributed radially around the drive wheel and adapted to be driven by rotation of the drive wheel, and a pivoting connector configured to enable the side sweeping system to pivot laterally in response to contact with a wall while at least one of the brushes maintains contact with the floor adjacent the wall while the apparatus is in operation, and the brushes move debris disposed on the floor adjacent the wall toward the front of the apparatus.
