An electric blower includes a motor unit, a shaft, a centrifugal impeller, a fan cover, a motor unit case, and a bracket located away from centrifugal impeller and toward motor unit in a direction in which a central axis of the shaft extends. The bracket includes a first portion located outward of the vent in a radial direction, and a second portion located outward of the first portion and outward of an outer circumference of the motor unit case in the radial direction. A first airflow passage and a second airflow passage are formed in the bracket, the first and second airflow passages communicate with an airflow passage formed by the centrifugal impeller and the fan cover.

Systems and methods for providing a vacuum cleaner with sliding vacuum head assembly. The vacuum head assembly comprises, for example, a vacuum motor, a dust bin, and a fan. The vacuum clean is configured for cleaning high and low surfaces based on a position of the vacuum head assembly along the vacuum tube.

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 particle suction nozzle including a body that has a suction mouth as well as at least a portion of a fastening system designed to link the nozzle to a support. The fastening system has at least one tubular insert made of elastically deformable material rigidly connected to the body and designed to be fitted onto a linking element rigidly connected to the support, and once fitted, to be immobilized in relation to the linking element and at a distance from the support. A suction device includes the suction nozzle.

A floor cleaning device includes a floor covering compartment having a cleaning opening, a vacuum generating device, a suction pipe that connects the floor covering compartment to the vacuum generating device so that suction force is applied on the surface covered by the cleaning opening, a cleaning head body that holds the floor covering compartment, and a vibrating device that causes vibration of the floor covering compartment relative to the cleaning head body. The periphery of the cleaning opening is adapted to contact a surface to be cleaned so that a sealed cleaning space is formed inside the floor covering compartment and over the portion of the surface covered by the cleaning opening. Strong negative pressure is built up in the sealed cleaning space to enhance suction efficiency. Vibration temporarily breaks the sealed state to facilitate moving of the floor covering compartment.

A trap for use with a vacuum cleaner includes a trap body formed in a substantially cylindrical shape. The trap body includes a suction opening formed at one axial end to suck in a target to be trapped and an insertion opening formed at the other end to be inserted into a vacuum cleaner. An adhesive is provided on at least a portion of an inner surface of the trap body. The trap for use with a vacuum cleaner includes a net portion. The net portion blocks a plane orthogonal to an axial direction of the trap body. The net portion includes a net formed in at least a portion to transmit air sucked in through the suction opening. The trap body includes a protrusion formed on at least a portion in a circumferential direction of an outer surface thereof to protrude outward.

An accessory tool for a vacuum cleaner includes a conduit and a nozzle. The conduit includes a first end coupled to the vacuum cleaner and a second end opposite the first end. The nozzle is coupled to the second end and includes a first portion with a first set of teeth and a first channel with an opening opposite the first set of teeth. The nozzle also includes a second portion with a second set of teeth and a second channel with an opening opposite the second set of teeth. The first set of teeth interlock with the second set of teeth, and are configured to cause the first portion and the second portion to pivot together relative to the conduit between a closed position and an open position. The nozzle is movable along an outer surface of the conduit from the second end toward the first end.

A vacuum nozzle with a vacuum hose receptacle and two wing members pivotably connected to each order. Each wing member has a corresponding opening that is in fluid communication with the vacuum hose receptacle. The two wing members may be positioned at different angles to effectively vacuum a flat surface or at a corner of any degree angle formed from two adjacent surfaces (e.g., wall and floor or two vertical walls).
