A method for controlling a clearing process in a vacuum cleaning device, wherein the vacuum cleaning device comprises at least one filter, which is cleared regularly. The method proposed allows, in particular, differential-pressure-dependent filter clearing in accordance with requirements, during which filter aging and/or filter wear can also be taken into account. In a second aspect, the invention relates to a vacuum cleaning device by means of which the proposed control method can be carried out. For this purpose, the vacuum cleaning device can comprise, in particular, a filter clearing unit.

The present disclosure provides an autonomous robot, configured to perform a cleaning function and an emptying function.

A cleaner is disclosed. The cleaner includes: a housing having an introduction opening through which air is introduced; a filtering unit configured to be mounted in an inner space of the housing, and defining a dust collection space between the filtering unit and an inner surface of the housing; and a cleaning unit surrounding the filtering unit and configured to be raised and lowered. When the cleaning unit is in an initial position at least a portion of the cleaning unit is connected to an air introduction path extending from the introduction opening such that the cleaning unit guides a flow of introduced air. A guide edge extends from a lower portion of the cleaning unit toward a bottom of the dust collection space, and a surface of the guide edge facing the inner surface of the housing is inclined.

A wet-dry vacuum device assembly comprises a housing and a motor-fan assembly mounted in the housing. The motor-fan assembly is arranged to generate an air flow along an airflow path between a dirty air inlet and a clean air exhaust. The wet-dry vacuum device comprises a tank positioned along the airflow path and arranged to capture liquid entrained in the dirty air flow. The wet-dry vacuum device further comprises a removable pump accessory mountable to the housing. The removable pump accessory comprises pump and a fluid inlet in fluid communication with the tank and the pump. A fluid outlet is in fluid communication with the pump and connectable to an exterior hose. The pump is arranged to move captured liquid in the tank from the fluid inlet to the fluid outlet.

A dust collector for use with a hand-held power tool. The dust collector includes a housing, a motor positioned in the housing, and a telescoping suction pipe coupled to the housing. The dust collector also includes a suction fan coupled to the motor and operable to generate a vacuum in the suction pipe. The dust collector further includes a dust container coupled to the housing and positioned upstream of the suction fan, and a filter at least partially arranged in the dust container. The dust collector also includes a filter cleaning mechanism including a solenoid configured to be actuated by a controller to dislodge dust from the filter when either the motor or the suction fan transitions from an active state to an inactive state.
