A free-floating, sweeper head for use in a pneumatic chip collector system. The sweeper head includes a sweeper mechanism and a connector configured to be coupled to the pneumatic system. The sweeper head includes a horizontal plate, a skirt that extends transversely from the plate along a portion of a perimeter of the plate, and an aperture that extends through the plate and is in communication with the connector. The sweeper mechanism has a drive disposed on the plate, a set of blades disposed below the plate, and a shaft that operatively couples the drive and the set of blades. The skirt creates an opening below the plate that is adapted to receive at least one chip when the set of blades rotates.

A vacuuming-off device includes at least one vacuuming-off unit that has at least one interface. The interface is mechanically and electrically connectable to a hand-held power tool, in particular to a hammer drill and/or chipping hammer, in at least one first application. The vacuuming-off device further includes an adapter unit that, in at least one second application, is connectable to the interface. The adapter unit has at least one connecting unit that is connectable to at least one energy supply.

A dust collector in one aspect of the present invention comprises a dust collection portion, a communication portion, and an interlock operation control portion. When the communication portion receives an interlock command transmitted from an electric working machine, the interlock operation control portion makes the dust collection portion operate interlocking with the electric working machine. The interlock operation control portion includes a storage portion, in which identification information specific to the electric working machine with which the dust collection portion is to be made to perform the interlock operation is stored.

A dust collector for electric power tool includes a body case, a dust box, a nozzle, and a dust collecting route. The dust box includes a dust-collector-side exhaust port and is installable on an electric power tool. The dust box internally includes a filter. The nozzle is disposed to the body case and includes a suction opening on a front end. The dust collecting route is disposed from the suction opening to the dust-collector-side exhaust port passing through the filter. The dust box includes a box main body that includes a vibration applicator configured to directly apply a vibration to the dust box by a rotating operation of an operation knob.

Methods and devices relating to loose debris chip shielding for dust free tile removal and ordinary tile removal projects. During the tile removal process, a chipping hammer powers a chipping hammer blade that breaks up tiles into pieces. The larger, heavier pieces are simply pushed away, but smaller debris chips break off with enough force to send them flying up in the air and in different directions landing in undesirable locations. The methods and devices herein protect equipment, environments, and individuals from damage caused by loose debris chips during tile removal. A shield with several degrees of freedom moves freely in response to chipping hammer vibrations and blocks loose flying debris chips, deflecting them toward the ground.

A surface cleaning apparatus has a cyclone chamber provided in an air flow path. The cyclone chamber has a screen assembly with an outlet section, a longitudinally spaced apart distal section and a longitudinally extending porous section. The outlet section includes a non-porous member extending longitudinally inwardly an outlet section length from an outlet end of the outlet section to a longitudinally inwardly positioned inlet end of the outlet section. The outlet end of the outlet section overlies a cyclone air outlet. The porous section extends longitudinally inwardly from an outlet end of the porous section that is located at the inlet end of the outlet section. The inlet end of the outlet section has a width in a direction transverse to the longitudinal direction that is greater than a width of the outlet end of the porous section in the transverse direction.

A dust collector can be used with a hand-held power tool. The dust collector includes a housing, a telescoping suction pipe coupled to the housing, and a suction fan positioned within the housing and operable to generate a vacuum in the suction pipe. The suction pipe is configured to telescope toward and away from the housing. The suction pipe includes an outer pipe supported by the housing, and an inner pipe slidably received into the outer pipe.

This document discloses a valve comprising a main valve closure body, arranged on a low pressure side of the valve and moveable to open towards the low pressure side, a control body, fixedly connected to the main valve closure body, such that a position of the main valve closure body is fixed relative to a position of the control body, a control chamber, partially defined by the control body, whereby a volume of the control chamber is variable in relation to the position of the control body, and a control fluid connector for controlling a pressure in the control chamber. The document also discloses use of the valve in a separator for separating dust and debris from an airflow, a separator comprising such a valve and a method of operating a separator.

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 surface cleaning apparatus includes a surface cleaning head having a dirty air inlet and an upper section mount moveably coupled to the surface cleaning head. An upper portion is mounted to the upper section mount. The upper section comprises a wand. A portable surface cleaning unit is removably mounted to the upper portion. An air flow path extends from the dirty air inlet to a clean air outlet and includes an upstream portion comprising the wand and a flexible air flow conduit downstream of the wand. Each of the wand and the portable cleaning unit can be separately removable from the upper section mount.
