A dust collection device which includes a support plate comprising a protrusion rib formed to extend from one surface, and an opening; and an opening/closing cover configured to open or close the opening of the support plate while one side of the opening/closing cover is fixed to the support plate, the opening/closing cover being configured to be spaced apart from the protrusion rib to open the opening and to be in close contact with the protrusion rib to close the opening. The protrusion rib extends more at a first point that is further from the one side of the opening/closing cover fixed to the support plate than a second point closer to the one side of the opening/closing cover.

Provided are a tray and a cleaning apparatus system. The tray includes: a tray body, where a roller brush accommodation region is arranged on an outer surface of the tray body, and a mounting cavity is provided in the tray body; and a drying unit, where the drying unit is mounted in the mounting cavity, and the drying unit runs to perform drying treatment on the roller brush accommodation region and an object in the roller brush accommodation region. The tray may be used with a cleaning machine. When the cleaning machine is disposed on the tray, a roller brush on the cleaning machine is located in the roller brush accommodation region, and the drying unit runs to perform drying treatment on the roller brush accommodation region and the object in the roller brush accommodation region.

A cleaning device and methods for cleaning are provided. In one embodiment, the cleaning device includes a head assembly, a body assembly, and a handle assembly. The cleaning device also includes components that enable the cleaning device to operate in dry cleaning modes and wet cleaning modes. Dry cleaning modes can employ a vacuum assembly, including a motor, tubing, and a fluid recovery tank in order to draw in debris and waste into a fluid recovery tank. Wet cleaning modes can further employ a fluid supply tank, a pump, and tubing in order to supply fluid to a brushroll to aid in a cleaning process.

The present disclosure relates to a cleaner system including: a cleaner; a cleaner station; and an imaginary plane including an imaginary suction flow path through line penetrating a suction flow path in a longitudinal direction and an imaginary suction motor axis defined by extending a rotation axis of a suction motor, in which when the cleaner is coupled to the cleaner station, the plane penetrates at least a part of the cleaner station, such that a center of gravity of the cleaner is disposed to pass through a space for maintaining balance of the station, and as a result, it is possible to stably support the cleaner and the station while preventing the cleaner and the station from falling down.

Provided are cleaning robot and robot system, the cleaning robot includes robot main body and cleaning box assembly, the robot main body is provided with debris inlet channel, the cleaning box assembly is detachably mounted at one side of robot main body, and includes debris storage box and liquid storage box detachably connected thereto, the debris inlet channel, the debris storage box, and the liquid storage box are sequentially arranged in advancing direction of robot main body, the debris storage box is provided with air inlet and debris collection cavity, the air inlet is butted with the debris inlet channel, the debris collection cavity communicates with the debris inlet channel via the air inlet, the liquid storage box is provided with debris discharge port, the debris discharge port pneumatically communicates with the debris collection cavity, and the debris discharge port discharges debris in it with vacuum negative pressure.

A vacuum cleaner includes a hand-held device and the hand-held device has a housing defining an air inlet and an air blowing port at a front end thereof, the air blowing port being disposed adjacent to the air inlet; a dust cup disposed in the housing and connected to the air inlet; and an electric motor defining a motor chamber in communication with the dust cup, in which an airflow entering through the air inlet flows out of the air blowing port after flowing through the dust cup and the electric motor.

A cleaning apparatus includes a vacuum cleaner, a stand, a first coupling portion, a plurality of suction units, and an extension holder. The vacuum cleaner includes a main body configured to receive and discharge air. The vacuum cleaner is mounted in the stand. The first coupling portion is formed in the stand and is positioned behind the vacuum cleaner. One of the suction units is selectively coupled to an air inlet through which air is suctioned into the main body. A first connector coupled to the first coupling portion is located at one end of each of the suction units. The extension holder includes a second connector and second coupling portions. The second connector is coupled to the first coupling portion. The second coupling portions are respectively positioned on either side of the second connector.

A vacuum cleaner may include a body having a handle end and an attachment end, the attachment end being opposite the handle end along a longitudinal axis of the body, a dust cup disposed between the handle end and the attachment end, a suction motor disposed between the handle end and the attachment end, a body latch configured to releasably engage an accessory, and a body toggle configured to cause the body latch to transition between a releasing position and a retaining position, the body toggle being positioned closer to the handle end than the attachment end.

A cleaner includes a first extension pipe connected to a suction portion contacting a surface to be cleaned, and a second extension pipe coupled to a cleaner body having a driver generating suction force, and rotatably coupled to the first extension pipe. The first and second extension pipes operate in a first arrangement configured to allow the second extension pipe to be arranged in a longitudinal direction of the first extension pipe, and a second arrangement configured to allow the second extension pipe to rotate in a first direction from the first arrangement such that the first extension pipe and the second extension pipe are arranged to face each other. Such configuration enables a user to increase cleaning efficiency.

A cleaner holder includes a first body having a first charging port configured to charge a cleaner, a second body protruding from the first body to support the cleaner, and a battery accommodating space recessed in one surface of the second body and configured to accommodate a battery detachably mounted to the cleaner. A second charging port configured to charge the battery is provided in the second body.
