According to one embodiment, a handy-type vacuum cleaner has a vacuum cleaner main body, a gripping part for use for gripping the vacuum cleaner main body, and a blower attachment to be attached to/detached from the vacuum cleaner main body. The vacuum cleaner main body includes an electric blower, a dust-collecting device, a main body connecting port, a suction air path, and an exhaust air path. The dust-collecting device stores the dust and dirt sucked by driving of the electric blower. The blower attachment is inserted into/extracted from the main body connecting port. The suction air path communicates between the main body connecting port and the dust-collecting device. The exhaust air path communicates with the exhaust side of the electric blower. The exhaust air path communicates with the blower attachment when the blower attachment is inserted into the main body connecting port.

A gas discharger connected to a source of pressurized gas comprises a gas channel that is opened to discharge the pressurized gas. A vacuum source can be separately or simultaneously operable with the gas discharger by using the pressurized gas or by using electrical power.

A coupling for a tube includes an attachment and a housing. The attachment is attached to the tube and has a barrel-shaped exterior surface. The housing contains the barrel-shaped exterior surface such that the attachment is rotatable in the housing while not being removable from the housing. The coupling thereby allows easy rotation of the tube within the coupling. The coupling may be utilized to attach the tube to another tube or to another structure.

Provided is a structure including a sound absorption section provided in an air flow path on an exhaust side of a fan, traversing a joint portion between a first main housing and a second main housing. The sound absorption section has a double wall structure including an inner wall facing the air flow path and an outer wall spaced outward from the inner wall. A sound absorption member is interposed in a sound absorption chamber between the inner wall and the outer wall of the sound absorption section. A communication hole communicating with the air flow path and the sound absorption chamber is formed in the inner wall of the sound absorption section at a position away from the joint portion.

The Garage Air-N-Vac Station is an integrated wall-mounted vacuum, blower, and air compressor. The integrated system includes provisions for wall-mounting, tool and accessory storage, a wand hanger, and hose hangers for the combined vacuum/blower hose as well as the compressed air hose. The vacuum and blower sections of the machine are powered by a combination vacuum/blower motor, with the vacuum function utilizing the intake side of the vacuum/blower motor, and the blower function utilizing the discharge side of the vacuum/blower motor. A tankless compressor provides compressed air at full capacity. The machine is operated by a single 3-way control switch (On-Off-On) to activate either the vacuum/blower function or the compressor function. The elements that make this invention new and novel relate to its multi-function capabilities, combined with the integrated wall-mounting, tool, and hose storage system that has been optimized for ease of installation, convenience of use, organization, and appearance.
