A dust collection system for a power tool can collect, with an ordinary bit, dust with a flexible hose connected. A dust collection system for a power tool includes a power tool to receive a tip tool protruding frontward and including a tool body, a cylindrical first dust collection attachment attachable to the tool body and covering the tip tool over its entire circumference with the first dust collection attachment being attached, a second dust collection attachment attachable to the tool body and including a dust collector, and a flexible hose to connect the first dust collection attachment and the second dust collection attachment to collect dust sucked through the first dust collection attachment into the dust collector included in the second dust collection attachment.

A vacuuming broom assembly includes a vacuum pack that is wearable on a user's back. The vacuum pack has an intake for urging air inwardly therein when the vacuum pack is turned on and a suction hose is fluidly coupled to the intake. A broom is provided that has a head and a handle. A suction manifold is coupled to the broom and the suction manifold has a pair of inlet ports and an exhaust port. The suction hose is fluidly coupled to the exhaust port such that the suction manifold is in fluid communication with the vacuum unit. Each of the inlet ports is aligned with the head of the broom for sucking up debris that is produced from sweeping. In this way the vacuum unit reduces airborne particles produced from sweeping.

The invention refers to a suction hose (12) adapted for use with a suction device (2), in particular vacuum cleaner or dust extraction system, comprising a radio receiver (28) for receiving radio signals (30). The suction hose (12) comprises a first end (14) adapted to be connected to a suction opening (10) of the suction device (2) and an opposite second end (16) adapted to be connected to an air outlet (18) of a hand-held electric or pneumatic power tool (20), and a communication device (32) located at or near the second end (16) of the suction hose (12). The communication device (32) is designed to realise only unidirectional communication from the communication device (32) to the suction device (2).

A closure flap on a vacuum inlet valve assembly or housing pivots between an open first position and a closed second position. When the closure flap is in the open first position, it is offset from a central longitudinal axis of the vacuum inlet valve housing. When the closure flap is in the closed second position, it intersects the central longitudinal axis. The closure flap has a resilient and compressible protrusion that releasable locks the closure flap in each position.

A reconfigurable surface cleaning apparatus is provided.

A vacuum collection vehicle may include a chassis, a vacuum container supported by the chassis, a vacuum source separated from the vacuum container by an intermediate wall and a filter. The vacuum source is in pneumatic connection with the filter through the intermediate wall. A plurality of discharge conduits extend through the intermediate wall, extend over and above the filter, along the roof of the vacuum container. The plurality of discharge conduits have a plurality of respective outlets at different locations within the interior of the vacuum container for discharging collected material into different collection receptacles. The filter is sandwiched between the intermediate wall and the plurality of discharge conduits.

A portable surface cleaning apparatus has a main body and air treatment member assembly is removably mounted to the main body. The air treatment member assembly air outlet and/or the suction motor inlet end is provided at the lower end of the air treatment member assembly when the surface cleaning apparatus is located on a floor and a pre-motor filter underlies the air treatment member assembly and/or the suction motor.

A suction hose for a vacuum cleaner including a hose portion, which has a flexible dust removal hose body and a flexible jacket hose body, in which the dust removal hose body is arranged, wherein a suction flow channel for conducting a suction flow to the vacuum cleaner extends between longitudinal ends of the hose portion, which suction flow channel is bounded by a hose jacket of the dust removal hose body, a connection piece for connecting to the hand-held power tool or to the vacuum cleaner is arranged at at least one longitudinal end of the hose portion, and the jacket hose body and the dust removal hose body extend into an interior of a hose receptacle of the connection piece such that the dust removal hose body is sheathed by the jacket hose body into the hose receptacle.

A surface cleaning apparatus is disclosed having a forward portion and a rearward portion. The forward portion has a dirty air inlet, a front side, a rear side and a forward bridging section, the forward bridging section having a rearwardly extending air flow passage that is downstream from the dirty air inlet. The rearward portion positioned rearward of the forward portion, the rearward portion comprising a front side, a rearward side, a rearward bridging section, a lower planar surface, an upper surface and an up flow duct, the rearward bridging section being spaced rearward of the front side of the rearward portion. The rear side of the forward portion is spaced from and faces the front side of the rearward portion and the forward bridging section is connected to the rearward bridging section.

A vacuum inlet valve assembly has a housing configured to be mounted exterior to a preexisting wall in a structure such that the housing is connected with a conduit and the conduit is exterior to the wall and retains a hose therein, and the hose is adapted to be pulled out from a stored position within the conduit external from the wall to an extracted position, and when in the extracted position, an end cap or hose plug on the hose is releasably connected with a connection assembly in the housing. A portion of the conduit is clear or translucent or transparent so an operator can watch the end cap or hose plug approach the connection assembly.
