A cleaning device including a cleaner and a station on which the cleaner is mounted is provided. The cleaner includes a suction head, a dust container to collect dust contained in air vacuumed through the suction head, and an extension tube connecting the suction head with the dust container. The station includes a main body configured to suck dust of the dust container of the cleaner and contain the dust, a support configured to support the main body and guide rotation of the main body, and a rotation driving device disposed in the support and configured to transmit a rotational force to the support.

A floor cleaning machine including a handle that pivots relative to a base about a pivot axis. A recovery tank is coupled to the handle in fluid communication with a suction motor assembly to receive and store fluid and dirt drawn through a suction nozzle. The floor cleaning machine further includes an expandable hose fluidly communicating the recovery tank and the suction nozzle. The hose is in an expanded configuration when the handle is pivoted about the pivot axis to a reclined position. The hose is in a retracted configuration when the handle is pivoted about the pivot axis to a substantially upright position. The hose at least partially wraps around the pivot axis with the pivot axis being between a portion of the hose wrapped around the pivot axis and the surface being cleaned in the expanded and the retracted configurations.

A vacuum assembly includes a vacuum portion having a vacuum source with an inlet and an outlet and a tank portion. A three-way inlet valve fluidly connects the inlet to the vacuum source with the tank portion when in a first position and fluidly connects the inlet to the vacuum source with an inlet to a surrounding environment when in a second position. A three-way outlet valve fluidly connects the outlet of the vacuum source with an outlet to the surrounding environment when in a first position and the outlet of the vacuum source with the tank portion when in a second position.

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 suction apparatus is provided, including a suction head, a suctioned material container for accommodating suctioned material, a suction blower device arranged on the suction head, and a channel device associated with the suction blower device for conducting process air at the suction head, wherein a pipe element with an adapter device is provided, wherein the adapter device is fluidically releasably connectable or connected to a suction port of the suction apparatus for performing a suction operation and the adapter device is fluidically releasably connectable or connected to a first air outlet for performing a blowing operation, and wherein an air inlet opening of a second channel for supplying process air from the suction blower device to a second air outlet is closed by at least one wall element of the adapter device when the adapter device is properly connected to the first air outlet.

An artificial intelligence cleaner may determine a length of a head from user cleaning information including a height of a user, a pressure sensing value applied to the head and a head angle between the head and the ground using a head length calculation model and control a head motor to have the determined length of the head.

A surface treatment apparatus may include a coupling, a handle, an accessory coupled to the coupling, and a toggle proximate the handle. The accessory may have at least two operational states. An actuation of the toggle may cause the accessory to transition between operational states.

The disclosure provides a fan assembly and a vacuum cleaner with the fan assembly. The fan assembly includes a motor, an impeller and a fan housing. The impeller is driven by the motor, which includes an impeller air outlet and an impeller air inlet. The impeller air inlet is located in the axial direction of the impeller, and the impeller air outlet is located in the radial direction of the impeller. An air channel is formed inside the fan housing, and the impeller is at least partially housed in the fan housing. The impeller rotates relative to the fan housing about the rotational axis, the generated airflow enters the air channel during the rotation of the impeller, and the height of the fan housing in the direction of the rotational axis increases along the direction of the air flow.

A vacuum cleaner to suction dust generated by a machine tool, wherein the vacuum cleaner is actuatable by an electric device in the shape of the machine tool or an energy storage module for the electric power supply of the machine tool, which has a drive motor to drive a tool holder on which a tool provided to process a workpiece is arranged or is arrangeable, wherein the vacuum cleaner has a vacuum housing with a dirt collection chamber to receive dirt separated from a suction flow and a suction unit to generate the suction flow, wherein a suction inlet is present on the vacuum housing to connect a suction hose to establish a current connection for the suction flow with the machine tool, wherein the vacuum cleaner has an external communication apparatus for a wireless control connection to a wireless communication interface of the electric device and to receive at least one control command to control, the vacuum cleaner via the control connection.

A handheld electric vacuum configured to perform sucking work includes: a pipe including a suction port at one end and a discharge port at the other end; a blower provided outside the pipe and driven by an electric motor; a handle provided outside the pipe and near the discharge port in a longitudinal direction of the pipe, and configured to be held by a hand; and an ejector provided near the suction port in the longitudinal direction of the pipe, and configured to feed pressurized wind generated by the blower into the pipe from around the pipe, and to eject the pressurized wind to the discharge port.
