The filter can receive timely maintenance. A dust collection system includes a hammer drill, a dust collection attachment connected to the hammer drill and including a dust collection motor that generates a suction force and a filter that catches sucked dust, and a dust collection controller that monitors a state of the dust collection attachment to determine a time to perform maintenance.

A dust collecting system includes a power tool and a stationary dust collector. The power tool is configured to perform processing operation on a workpiece by driving a tool accessory. The stationary dust collector is configured to be placed separately from the power tool and to collect dust generated by the processing operation. The power tool includes a first motor and a driving mechanism configured to drive the tool accessory by power of the first motor. The dust collector includes a second motor and a fan configured to be rotationally driven by the second motor to generate air flow for collecting dust. The dust collecting system includes a control device configured to control a rotation speed of the second motor according to a driving state of the power tool.

Disclosed herein area robot, a dust collection device, and a dust collection method. The robot includes a first moving mechanism, a second moving mechanism, a dust collection part, and a dust collection part moving mechanism. The first moving mechanism is disposed on a base body, and moves a workpiece to be cut in a first axis direction. The second moving mechanism is supported on the base body via support portions, and moves a cutting body in a second axis direction orthogonal to the first axis direction. The dust collection part is disposed to face the cutting body, and collects cutting chips generated by the cutting of the workpiece to be cut using the cutting body. The dust collection part moving mechanism moves the dust collection part between a first position close to the workpiece to be cut and a second position remote from the workpiece to be cut.

A suction apparatus includes a suction apparatus housing, a suction hose, at least one suction apparatus communication unit, and at least one sensor device which comprises at least one sensor unit designed to detect at least one operating signal of a machine tool, in particular of a handheld machine tool. The suction hose is assigned the at least one sensor device. The at least one sensor device has at least one signal processing unit and at least one sensor device communication unit. The signal processing unit is designed to receive the operating signal from the sensor unit and process said operating signal into at least one communication signal, and the sensor device communication unit is provided to establish at least one communication connection to the suction apparatus communication unit and to transmit the communication signal to the suction apparatus communication unit.

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 distal section has a distal section length in the longitudinal direction that is greater than the cyclone outlet port length.

The invention relates to an extraction device for a robot-assisted machine tool for surface processing. According to an exemplary embodiment, the extraction device comprises a housing with a vacuum nozzle and an outlet for connection of a hose. The extraction device also has a suspension that connects the housing to a mounting plate and is mounted on the mounting plate so as to be pivotable about an axis. A counterweight is connected to the suspension such that the counterweight substantially balances out the weight of the housing relative to the axis.

A compact dust removal system that can be mounted on a substantially rigid receptacle, such as a pail, found at construction sites. The compact dust removal system includes an array of cyclonic separators of different sizes disposed within a mesh filter. The system can be mountable to a pail such that an initial dust removal stage occurs by inertial separation along the interior surface of the pail. The system further includes a cyclone inlet manifold configured to distribute dust-laden air among the cyclonic separators at least partially based on the size of dust particles within the dust-laden air.
