Abstract: A dust collector includes a main-body housing and a motor assembly disposed in the main-body housing. The motor assembly includes a blower fan, which is disposed in the interior of the main-body housing; and a suction motor, which rotates the blower fan. The motor assembly generates suction force at a suction port, which fluidly communicates with the interior of the main-body housing. At least one filter is disposed in a fluid communication path between the suction port and the blower fan. A filter cleaning apparatus is configured to clean the at least one filter. A cleaning-control part is configured to actuate the filter cleaning apparatus after a power tool, which is fluidly connected to the suction port, stops operating.

Abstract: A surface-cleaning apparatus (1) includes: a main-body housing (2); a suction motor (6), which is housed in the main-body housing and is driven to recover a cleaning liquid from a surface of a cleaning target; a first tank (3), which houses the cleaning liquid to be supplied to the surface of the cleaning target; and a second tank (4), which houses the cleaning liquid recovered from the surface of the cleaning target. One tank of the first tank and the second tank has a tank-recessed portion (22) that is recessed from a portion of a surface of the one tank. The other tank of the first tank and the second tank has a lower surface (4A) that opposes a stationary surface on which the surface-cleaning apparatus sits.

Abstract: A dust collector cools a controller. The dust controller includes a body housing, a motor located inside the body housing, a fan rotatable by the motor, a controller that controls the motor, and a thermal insulator between the motor and the controller. The thermal insulator defines a flow channel through which an airflow generated by the fan passes.

Abstract: An upright vacuum cleaner includes a main-body part (10) having a dust-collection chamber (14) fluidly connected to a motor chamber (13) via a coupling pipe (15). A fan (13f) and a motor (13m) are housed in the motor chamber. A cleaner head (20) is pivotably and fluidly connected to the main-body part and suctions air through a suction opening (23) when a suction force is generated by the fan and the motor in the motor chamber. A straight suction passageway (24) extends through a central portion of the interior of the cleaner head in plan view. One or more batteries (50) is/are disposed within the cleaner head spaced apart (outward) from the suction passageway in the plan view.

Abstract: A dust collector includes a dust-collector main body, a coupling-hose part, an operation unit, and a belt or harness. The dust-collector main body serves to collect dust by generating a suction draft (partial vacuum). The dust-collector main body includes a housing, a motor, a dust-collection chamber, and at least one battery pack mount. The belt or harness is attached to the dust-collector main body and is designed for the user to carry the dust-collector main body on his or her back. The operation unit is connected to the dust-collector main body via an external, flexible cord. The operation unit includes one or more LEDs for illuminating the area to be cleaned and an ON/OFF switch for controlling operation of the motor.

Abstract: A dust collector (dust extractor) (10) has a wireless communication unit (25; 30; 31; 32; 33; 34; 35; 36; 37) that remotely operates (controls) a dust-collection mechanism disposed in a main body (11) of the dust collector (10). The wireless communication unit of the dust collector (10) may communicate with a paired tool wireless-communication device (2b) associated with a tool (2) so that the dust-collection mechanism of the main body 11 is started and stopped in a linked manner with the starting and stopping of the tool (2), thereby improving ease of operation and work efficiency, because the dust collector (10) automatically turns on and off in coordination with operation of the tool (2).
