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.

The present invention provides a dust collector apparatus, comprising: a housing, an airflow generation module and a filter. The housing has one side formed at least one intake vent-hole and another side formed of at least one exhaust vent-hole. An inner side of the housing has an airflow channel formed between the intake vent-hole and the exhaust vent-hole. The airflow generation module comprises an airflow drawing unit for drawing an airflow in order to form the airflow channel between the intake vent-hole and the exhaust vent-hole, a control module for controlling the airflow drawing unit, and a power module. The filter is detachably arranged at the intake end and used for filtering dust in the air sucked by the airflow drawing unit. The dust collector apparatus of the present invention allows the dust particles to be properly collected by the filter without secondary scattering, and guides the airflow to be exhausted smoothly.

An adapter for connecting a dust storage container to a vacuum source includes a first end and a second end. The first end is configured to fluidically connect to an opening in the dust storage container. The second end is fluidically connected to the first end and is configured to connect to an operative end of the vacuum source.

A cyclone pre-separator for positioning on a particle collecting container, the cyclone pre-separator including a box-shaped housing and a cyclone unit arranged in the housing, the cyclone unit including an air inlet, an air outlet, and a particle outlet arranged on a underside of the cyclone pre-separator, where the housing has an air inlet hose port connected to the air inlet and an air outlet hose port connected to the air outlet, and has lower housing couplers, adapted to provide a releasable, vertically tension-proof coupling to the particle collecting container, when the cyclone pre-separator is positioned on the particle collecting container.

A vacuum cleaner station is configured to operate with first and second power tools, each power tool having an electrical plug. The vacuum cleaner station includes a housing, a suction source, a first hose port, a first valve, a first hose, a second hose port, a second valve, a second hose, a debris collection chamber, a battery receptacle, a battery pack receivable in the battery receptacle, a first electrical outlet on the housing, a first sensor configured to detect when the first power tool is receiving power from the battery pack, a second electrical outlet on the housing, a second sensor configured to detect when the second power tool is receiving power from the battery pack, and a controller electrically coupled to the suction source, the first sensor, the second sensor, the first valve, and the second valve.

A portable vacuum cleaner comprises a housing including a storage space and a lid coupled to the housing. The lid is moveable between an open position, in which access to the storage space is provided, and a closed position, in which access to the storage space is blocked. The vacuum cleaner further comprises a handle coupled to the housing, a suction source supported in the housing, a debris collection chamber in fluid communication with the suction source, and a first battery receptacle on the housing. The first battery receptacle is configured to selectively receive a first battery pack that is configured to provide power to the suction source. The vacuum cleaner further comprises a hose port on the housing and in fluid communication with the suction source.

The invention refers to a remote control (50) for controlling an operation status of a suction device (2). The remote control (50) comprises a radio transmitter (88) for transmitting a first radio signal (30) to the suction device (2) for turning on or off the suction device (2). It is suggested that the remote control (50) further comprises a radio receiver (90) for receiving a second radio signal (54) from a communication device (32) located at a second end (16) of a suction hose (12), which is connected to a suction opening (10) of the suction device (2) with its first end (14) and to an air outlet (18) of a hand-held electric or pneumatic power tool (20) with its opposite second end (16). The communication device (32) detects a current operation status of the hand-held electric or pneumatic power tool (20) and emits the second radio signal (54) indicative of the current operation status of the hand-held electric or pneumatic power tool (20). The remote control (50) derives from the received second radio signal (54) the current operation status of the hand-held electric or pneumatic power tool (20) and transmits a respective first radio signal (30) in order to automatically turn on or off the suction device (2) depending on the derived current operation status of the hand-held electric or pneumatic power tool (20).

A vacuum tool configured to be removably coupled to hose or wand of a vacuum includes a body including a first end, a second end, and a first longitudinal axis extending between the first end and the second end. The vacuum tool also includes a head coupled to the first end of the body, a connection portion coupled to the second end of the body and configured to couple the body to a hose or wand of a vacuum cleaner, and a brush coupled to the head. The brush includes an elongate support defining a second axis perpendicular to the longitudinal axis of the body and configured to couple the brush to the head, and a plurality of bristles positioned on the elongate support.

In a vacuum drill dust extractor having a pot-shaped housing through which a rotatably drivable drill can be passed axially, and having a piston unit which is arranged axially displaceably in the housing, cooperates with a drill-side stop, contains an induced draft blower device and can be set against an associated stop on the housing side by means of a spring over which it engages, a high degree of reliability and operational safety are achieved in that at least one induced draft blower provided with its own drive motor and an energy storage unit provided with a charging socket and associated with each motor driving an associated induced draft blower are provided in the piston unit.

A surface cleaning apparatus includes a surface cleaning head having a dirty air inlet and an upper section mount and an upper portion moveably mounted to the upper section. The upper portion includes 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.
