A system includes a power tool and a suction device that is connected to the power tool via a suction hose. The power tool is drivable into a wall or into a substrate by a negative pressure produced by the suction device. A method includes driving the power tool into the wall or into the substrate by using the negative pressure produced by the suction device that is connected to the power tool via the suction hose.

A flush valve, a dust collector provided with such a flush valve and a dust collection system, are disclosed. The flush valve includes a valve body and a valve spool. The valve body is internally provided with a fluid passageway. The valve body is provided with an inlet, a first outlet and a second outlet. The first outlet is fluidly connected to a device to be flushed. The valve spool includes a movable part, a fixed part and an elastic part, the fixed part being provided in the valve body, and the elastic part elastically connecting said fixed part to the movable part. One end of the movable part being provided with a first spool land for blocking the first outlet. The first spool land being configured to be pushed away from said first outlet by fluid in the fluid passageway when the pressure drops due to blockage.

A hand vacuum cleaner and a mounting structure for the hand vacuum cleaner. The mounting structure has a base which is free standing on a floor and an upper portion comprising an air flow duct and a mounting apparatus provided at an upper end of the upper portion. The mounting apparatus has first and second laterally opposed first engagement members. The hand vacuum cleaner has first and second laterally opposed second engagement members. The hand vacuum cleaner is downwardly removably mountable to the mounting apparatus and the first and second engagement members are slideably interengagable. As the hand vacuum cleaner is moved downwardly to be mounted to the mounting apparatus, the first and second engagement members slideably interengage.

An energy storage module for use with an electric device in the shape of an electric hand-held machine tool or a vacuum cleaner, with the energy storage module having a wireless communication interface for wireless communication with an external communication apparatus arranged remote from the energy storage module and a module housing in which an electric storage device with at least one electrically rechargeable storage cell is arranged and on which a device interface is provided for detachable connection of the energy storage module to the electric device, with the device interface having electric device supply contacts for the electric energy supply of the electric device. The device interface of the energy storage module has a data interface separate from the device supply contacts, for data communication with the electric device.

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 sander including a housing, a motor housed in the housing and a platen which is driven by the motor. The sander also includes a dust chute, a dust container and a one-way valve disposed in the dust chute. The one-way valve allows air to flow in a direction towards the dust container and limits the flow of air in a direction away from the dust container. The one-way valve allows air flow in the direction towards the dust containers through multiple different openings.

A dust collector for use with a hand-held power tool includes a housing, a suction pipe coupled to the housing, and an electric motor positioned in the housing. The dust collector additionally includes a suction fan driven by the electric motor and operable to generate a vacuum in the suction pipe, and a depth stop assembly. The depth stop assembly is configured to limit the axial movement of the suction pipe. The depth stop assembly is configured to be alternately positioned on opposite sides of the suction pipe in a first configuration and a second configuration, respectively.

A power tool assembly includes a hand-held power tool. A dust collector is coupled to and supported by the power tool. The dust collector includes a motor, a suction fan driven by the motor, and a dust container. A vacuum drill bit is also coupled to the power tool. The vacuum drill bit includes an internal passageway that is in fluid communication with the dust container of the dust collector.

A closure device for closing a particle capture volume, in particular a bag or a container, including an access element with an access element opening for providing an access to the particle capture volume, a closure slide which can be selectively displaced relative to the access element into a release position or into a closure position. In the release position the closure slide releases the access element opening and in the closure position closes the access element opening, and a locking mechanism for locking the closure slide in the closure position with respect to the access element, where the locking mechanism 6 for unlocking requires a defined unlocking element which is separate from the locking mechanism.

Embodiments of the present invention provide a wireless dust collection system capable of integration into an existing or new dust collection configuration and capable of wireless activation in response to the activation of a connected workshop implement or in response to a user input through a user interface. The wireless collection system has at least one gate mechanism assembly, at least one wireless trigger assembly, an intermediary hub, a collector, a collector bin, and at least one wireless control interface.
