The air treatment member is removably mounted to the portable surface cleaning unit and secured in position by an air treatment member lock. The portable surface cleaning unit is secured in position by a portable surface cleaning unit lock. When the portable surface cleaning unit is mounted to the upper portion and the upper portion is in the storage position, the portable surface cleaning unit actuator is provided on an upper end of the portable surface cleaning unit and the air treatment member release actuator is provided on an upper end of the air treatment member.

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.

A dust collecting device for a power tool, the dust collecting device having a lamella filter, a rotatable shaft and a lamella holder. In the collecting container of the dust collecting device, the lamellae of the filter can be set in an axial movement by a rotary movement of the shaft which is mediated by the lamella holder, which is interrupted when a first profile of the shaft and a second profile of the lamella holder are moved with respect to each other and are not in engagement with each other. This enables the lamellae to return to their original position, the return of the lamellae to this original position causing the lamellae to vibrate, which leads to the filter being cleaned. A power tool which can have a proposed dust collecting device, as well as a method for operating a power tool and for cleaning a filter is also provided.

The present disclosure relates to a dust extractor (1) comprising a dust cyclone container (3) comprising a dust inlet (2) leading into the dust cyclone container (3), the dust extractor (1) further comprising a fine filter section (12) adapted to receive at least one fine filter part (15) downstream the dust cyclone container (3). A contaminated side of the fine filter part (15) is adapted to be fluidly connected to the dust cyclone container (3) via an air channel (47) that at least partly is comprised in a lid arrangement (13,14) and runs between a cyclone channel connecting rim (23) and a first fine filter section channel connecting rim (40), when the lid arrangement (13, 14) is positioned over the dust cyclone container (3) and the fine filter section (12). A first lid part (13) is releasably attachable to the dust cyclone container (3) and a second lid part (14) is releasably attachable to the fine filter section (12).

An electric device in the shape of a machine tool or an energy storage module for the electric power supply of a machine tool, with the energy storage module having a module housing with a device interface for the detachable connection to the machine tool, with the machine tool having a drive motor to drive a tool holder on which a tool provided to process a workpiece is arranged or is arrangeable, with the drive motor being switchable using a switching element of the machine tool and/or the energy storage module, with the electric device having a wireless communication interface for wireless communication with an external communication apparatus, which forms part of a vacuum cleaner provided to suction dust generated by the machine tool and with the wireless communication interface being designed to send at least one control command to control, the vacuum cleaner as a function of a switching status of the switching element to the external communication apparatus via a wireless control connection.

The gate housing has a flow passage therethrough, the flow passage having an inlet and an outlet. The gate housing also includes a gate pocket configured to receive a blast gate and to allow the blast gate to slide therein between an open position and a closed position. The magnetic brake element is on the gate housing and includes a magnet mounted to the gate housing such that a magnetic force of the magnet extends into the gate pocket.

A method for controlling operation of a dust extractor, the method comprising; obtaining (S1) sensor data (235) related to an airflow (240) into the dust extractor, determining (S2) if the dust extractor is operating in a high airflow operating range based on the sensor data (235), and if the dust extractor is operating in the high airflow operating range, controlling (S3) a fan motor (210) of the dust extractor to reduce the airflow (240) to a reduced flow level (330, 3301) at or above a pre-determined airflow level (340) and below an obtainable flow level (310), wherein the pre-determined airflow level (340) is associated with a dust extraction capability of the dust extractor (100).

A dust collection system for a power tool can collect, with an ordinary bit, dust with a flexible hose connected. A dust collection system for a power tool includes a power tool to receive a tip tool protruding frontward and including a tool body, a cylindrical first dust collection attachment attachable to the tool body and covering the tip tool over its entire circumference with the first dust collection attachment being attached, a second dust collection attachment attachable to the tool body and including a dust collector, and a flexible hose to connect the first dust collection attachment and the second dust collection attachment to collect dust sucked through the first dust collection attachment into the dust collector included in the second dust collection attachment.
