A suction apparatus is provided, including a suction head, a suctioned material container for accommodating suctioned material, a suction blower device arranged on the suction head, and a channel device associated with the suction blower device for conducting process air at the suction head, wherein a pipe element with an adapter device is provided, wherein the adapter device is fluidically releasably connectable or connected to a suction port of the suction apparatus for performing a suction operation and the adapter device is fluidically releasably connectable or connected to a first air outlet for performing a blowing operation, and wherein an air inlet opening of a second channel for supplying process air from the suction blower device to a second air outlet is closed by at least one wall element of the adapter device when the adapter device is properly connected to the first air outlet.

A backpack tool kit including a backpack assembly with a casing and a battery pack received in the casing; and at least one tool connected to the casing of the backpack assembly and electrically connected to the battery pack. The backpack tool apparatus can be provided with multiple tools to simultaneously realize different operations and functions. Moreover, the tools are configured to be detachably connected to the backpack assembly, and can be replaced with different tools to realize different operations and functions according to needs.

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.

A downdraft table for cleaning electronic equipment includes a housing in the form of a cabinet having a grid-like upper surface with openings therein. A fan located within the housing below the upper surface draws air from above the surface downwardly through the grid. An air compressor and compressed air storage tank are also located within the housing below the upper surface for producing a source of compressed air and a hose is connected to the compressed air storage tank and extends upwardly above the upper surface. An air nozzle connected to the hose allows a workman to direct compressed air toward a piece of electronic equipment located on the upper surface. The upper surface preferably includes a turntable that is adapted to support the piece of electronic equipment thereby allowing the equipment to be rotated about a vertical axis as it is being cleaned. In addition, a ground wire is connected to the housing and has a spring clip at the distal end thereof which is adapted to be connected to the piece of electronic equipment for grounding the same.
