A surface cleaning apparatus comprises a base, a portable cleaning unit removably mounted to the base and comprising at least one air treatment member, a portable cleaning unit energy storage member and a portable cleaning unit suction motor. The portable cleaning unit suction motor is operable on power provided by the portable cleaning unit energy storage member when the portable cleaning unit is removed from the base. The surface cleaning apparatus comprises or is connectable to a power cord. When the portable cleaning unit is mounted to the base and when the surface cleaning apparatus is connected to an external source of power by the power cord, the portable cleaning unit energy storage member is chargeable on power provided by the power cord provided by the external source of power and the portable cleaning unit suction motor is concurrently operable on power provided by the power cord provided by the external source of power.

A wet surface cleaner operable in an upright cleaning mode, an auxiliary cleaning mode, and a lift-off cleaning mode. The surface cleaner has a canister assembly that is coupled to a body in the upright cleaning mode and removed from the body in the auxiliary cleaning mode and the lift-off cleaning mode.

The present application discloses a cleaning device and its dust box. The cleaning device may comprise a body, a dust box, and at least two fans. The dust box may be provided for connection to the body, the at least two fans are provided in the body for forming an airflow into and out of the dust box through the apparatus body. The dust box may be provided such that the airflow formed by each of the at least two fans can flow out of the dust box in different directions.

A reconfigurable surface treatment apparatus may include a wand and a pod removably coupled to the wand. The wand may have a first distal end that is configured to couple to a surface cleaning head and a second distal end that is configured to couple to a handle. The pod may include a suction motor assembly cavity, a battery cavity, and a dust cup cavity. The suction motor assembly cavity and the battery cavity may be disposed on opposing sides of a vertical plane, wherein the vertical plane extends along a central longitudinal axis of the pod. The dust cup cavity may be disposed between the suction motor assembly cavity and the battery cavity such that at least a portion of the dust cup cavity is disposed on each side of the vertical plane.

A vacuum cleaner comprises: a housing and a motor fan assembly mounted in the housing, the motor fan assembly arranged to generate an air flow. A removable dirt container is mountable on the housing and in fluid communication with a dirty air inlet and the motor fan assembly. A moveable dirt compactor is mounted in the dirt container and moveable between a stowed position and a dirt compacting position wherein the moveable dirt compactor is closer to one end of the dirt container in the dirt compacting position than in the stowed position. Wherein the dirt container comprises a primary handle for actuating the moveable dirt compactor with a first hand and a first auxiliary handle for allowing the user to grip with a second hand.

A moving robot and a control method thereof according to the present invention create a cleaning map including information on a travelable area of a cleaning area based on obstacle information, create a create a manufactured user map by changing forms and outlines by area with respect to a plurality of area configuring the cleaning map, and create a user map having a form similar to that of the cleaning are in a real indoor space by changing a form and an outline of a map including information on the travelable area according to an arear, so that a user easily recognizes a position of each area to input a cleaning command through the map, and a cleaning command with respect to an area which the moving robot cannot run is prevented from being input. Since the moving robot does not unnecessarily move an area, operation power consumption is reduced. The moving robot may run a cleaning area with limited power to efficiently clean the cleaning area.
