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 surface cleaning apparatus has a cyclone and a dirt collection chamber wherein the dirt collection chamber has a dirt collection chamber portion which is located axially spaced from the cyclone chamber and the dirt collection chamber portion has a transverse section in a plane transverse to the longitudinal axis of the cyclone that is annular.

A reconfigurable upright vacuum cleaner has a portable surface cleaning unit removably mounted to an upper portion. The portable surface cleaning unit has a suction motor and an air treatment member. The air treatment member is removably mounted to the portable surface cleaning unit and secured in position by an air treatment member lock. The portable surface cleaning unit is secured in position by a portable surface cleaning unit lock. When the portable surface cleaning unit is mounted to the upper portion and the upper portion is in the storage position, the portable surface cleaning unit actuator is provided on an upper end of the portable surface cleaning unit and the air treatment member release actuator is provided on an upper end of the air treatment member.

An adapter frame for mounting onto a base, in particular a suction device, a system box and/or a roller board, and for receiving a particle collecting container for a cyclone pre-separator, where the adapter frame includes a rectangular underside and adapter frame peripheral walls extending upwards from the underside, and lower adapter frame couplers, designed to provide a releasable, vertically tension-proof coupling to the base when the adapter frame is positioned on the base. The adapter frame on its upper side has a container receptacle for receiving the particle collecting container, the horizontal inner contour of which tapers towards the underside, so that the container receptacle is able to receive and horizontally stabilise a particle collecting container having an outer contour tapering downwards.

The disclosure relates to a system, comprising a vacuum apparatus having a vacuum apparatus housing and having at least one vacuum apparatus mains socket, the at least one vacuum apparatus mains socket being attached to the vacuum apparatus housing. According to the disclosure, the system additionally comprises a plug-in module, having a plug-in module communication unit, an electrical plug-in module mains plug unit, and a current control unit, which is designed to control an electrical current between the plug-in module and the vacuum apparatus.

The present disclosure relates to a cleaner system including: a cleaner; a cleaner station; and an imaginary plane including an imaginary suction flow path through line penetrating a suction flow path in a longitudinal direction and an imaginary suction motor axis defined by extending a rotation axis of a suction motor, in which when the cleaner is coupled to the cleaner station, the plane penetrates at least a part of the cleaner station, such that a center of gravity of the cleaner is disposed to pass through a space for maintaining balance of the station, and as a result, it is possible to stably support the cleaner and the station while preventing the cleaner and the station from falling down.

An interlocking adapter in one aspect of the present disclosure includes a current path, an electric load, a switch, and a controller. The controller turns on and off the switch in synchronization with a change of an alternating-current voltage received from an electric outlet of an electric apparatus in response to reception of an interlocking command signal from a working machine so as to supply a load current from the electric outlet to the electric load. The controller turns on and off the switch at a specified ratio of a time every 1/2 cycle of the alternating-current voltage.

A surface cleaning apparatus has a surface cleaning head and an upper portion moveably mounted to the surface cleaning head between a storage position and a floor cleaning position, the upper portion has upper portion laterally extending members. An above floor cleaning wand is removably receivable in air flow communication with the upper portion. The wand has wand laterally extending members, wherein, when the wand is received in air flow communication with the upper portion and the upper portion is in the storage position, the wand has a lower end and an upper end spaced from the lower end along a wand axis and the wand laterally extending members are positioned above the upper portion laterally extending members. A portable surface cleaning unit is removably mounted to the upper portion wherein, when the portable surface cleaning unit is mounted to the upper portion and the upper portion is in the storage position, the upper portion has lower mounting members which engage the upper portion laterally extending members and upper mounting members which engage the wand laterally extending members.

An upright surface cleaning apparatus is has a portable surface cleaning unit removably mounted to an upper portion that is pivotally mounted to a surface cleaning head. The surface cleaning apparatus is operable in a floor cleaning mode in which the portable surface cleaning unit is mounted to the upper portion and the above floor cleaning wand is inserted in an open upper end of the upper portion. The surface cleaning apparatus is also operable in an above floor cleaning mode in which the portable surface cleaning unit is mounted to the upper portion and the above floor cleaning wand is removed from the open upper end of the upper portion. When the surface cleaning apparatus is in the floor cleaning mode, the first mounting members of the portable surface cleaning unit engage the wand mounting members.

The gate housing has a flow passage therethrough, the flow passage having an inlet and an outlet. The gate housing also includes a gate pocket configured to receive a blast gate and to allow the blast gate to slide therein between an open position and a closed position. The magnetic brake element is on the gate housing and includes a magnet mounted to the gate housing such that a magnetic force of the magnet extends into the gate pocket.
