A vacuum tool is configured to be removably coupled to a hose or wand of a vacuum. The vacuum tool comprises a first portion, a second portion, a flexible portion and a mechanical joint. The first portion and the second portion are connected by the flexible portion and coupled by the mechanical joint, so these portions are in fluid communication from various angles. And the mechanical joint comprises a detent and multiple recesses coupled to the detent. As a result, a user can use the vacuum tool in various situations more conveniently by bending the mechanical joint.

The invention refers to a suction device (2), in particular a vacuum cleaner or a dust extraction system, comprising a collection container (4) with a suction opening (10), a vacuum generating device (8), a suction hose (12) with its first end (14) connected to the suction opening (10) and its second end (16) connectable to an air outlet (18) of a hand-held electric or pneumatic power tool (20), a radio receiver (28) for receiving radio signals (30), and a communication device (32) located at or near the second end (16) of the suction hose (12) and comprising a sensor element (34) for detecting an operation status of the power tool (20), and a radio transmitter (38) for transmitting a radio signal (30) indicative of the operation status of the power tool (20). It is suggested that the communication device (32) and the radio receiver (28) are designed to realise only unidirectional communication from the radio transmitter (38) of the communication device (32) to the radio receiver (28) of the suction device (2).

An environmental control unit comprises a housing, a vacuum cleaner, a filtration unit, and a blower. The vacuum cleaner is positioned in the housing and is configured to receive a tool contaminant stream produced by at least one tool. The vacuum cleaner filters particulate matter from the tool contaminant stream, thereby producing a filtered air stream. The filtration unit is also positioned within the housing and comprises at least one filter. The blower is positioned within the housing downstream of the filtration unit. The blower is configured to create negative air pressure within the second compartment to draw an area contaminant stream from an exterior of the environmental control unit into the housing. A second blower may also be present. The blower draws the filtered air stream and the area contaminant stream through the at least one filter in the filtration unit to produce a filtered mixture stream.

Cleaning turbine having a cylindrical shape with an axis or rotation and provided with a concave base surface facing toward the work zone, with an upper surface, opposite the base surface, and a circumferential surface interposed between the base surface and the upper surface. The cleaning turbine is provided circumferentially with a plurality of slits angularly distanced from each other, facing upward and passing through the base surface and the upper surface. The cleaning turbine is also provided with a plurality of lateral apertures each of which extends radially from the slits to the circumferential surface.

An apparatus for a vacuum cleaner for compensating air pressure surges, where a first air flow is flowable in a first flow direction through the apparatus and a second air flow is flowable in a second flow direction through the apparatus, includes a main body having a first cross-sectional area of flow and a flow resistance element. A free end of the flow resistance element projects from the main body and produces a second cross-sectional area of flow. The first cross-sectional area of flow is larger than the second cross-sectional area of flow such that the second air flow flowable in the second flow direction is reduced.

An apparatus for a vacuum cleaner for compensating air pressure fluctuations includes a main body through which an air flow is flowable in a flow direction, where the main body contains a passage opening, and a separating element, where the passage opening is separated from ambient air by the separating element. The separating element is movable such that, as a result of a movement of the separating element in a radial direction, a reservoir which receives an air volume is produced between the main body and the separating element such that a vacuum produced in the main body by the air flow is at least partially maintained.

A configuration apparatus for a system having an electric device in the shape of a machine tool or an energy storage module for the electric power supply of the machine tool and a vacuum cleaner to suction dust generated by the machine tool, with the vacuum cleaner being actuatable by the electric device via a wireless control connection, 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 vacuum cleaner having 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, with a suction inlet being present on the vacuum housing to connect a suction hose to establish a current connection for the suction flow with the machine tool, with the vacuum cleaner and the electric device having first communication interfaces according to a first communication standard to communicate via the wireless control connection.
