A dirt collection and separation module can include a suction air flow around the perimeter of a tank to ingest fine dust that becomes airborne during the emptying process. Additionally, a trash can suction nozzle around a rim, a hand vacuum docking station, and an auxiliary suction nozzle that can fluidly couple the hand vacuum.

Provided is a vacuum cleaner including a base configured to form a lower surface of a cleaner body; moving wheels provided at both side surfaces of the cleaner body and rotated for travel of the vacuum cleaner and also configured to support the cleaner body to be rotated in normal and reverse directions; and a dust container installed at a front of the moving wheels and configured to collect suctioned dust, wherein the base includes a center portion; a first half portion configured to extend to be inclined upward from a front end of the center portion; and a second half portion configured to extend to be inclined upward from a rear end of the center portion, and a rotating center of the moving wheels is located between the first half portion and the second half portion.

Provided is a cleaner including a dust collecting device for separating dust from air, wherein the dust collecting device includes a dust collecting case having a dust discharging port opened to discharge the collected dust; a discharge cover coupled to one side of the dust collecting case to open and close the dust discharge port; and a sealing member provided to extend from an inner surface of the dust collecting case to a coupling surface of the dust collecting case while being in contact with the dust collecting case and thus to be sealed when the dust discharging port is closed.

Methods and apparatus for debris separation generally comprise a vacuum hose attachment comprising a collar and an attachment body. The attachment body further comprises an external face, external face openings, nubs, valley, an internal baffle, and internal baffle openings. In some embodiments, the external face openings are arranged in a lattice pattern and separated by nubs in a first direction and valleys in a second direction. In some embodiments, the attachment body may further comprise handgrips. The present invention also includes a method for separating debris via a vacuum hose attachment.

A fan with airfoil blades is provided for a regenerative air vacuum street sweeper. The blades are formed using cut and pressed upper and lower panels which are welded at a forward edge to a rod to form the airfoil leading edge and welded at the rear edges to form the airfoil trailing edge. Pins extend laterally outwardly from the rod for mounting each blade in corresponding holes in the front and rear plates of the fan housing. The side edges of the blade are welded to the plates at a 9-11? angle of attack. The airfoil blades allow for reduced size, horse power, noise, and manufacturing and shipping costs.

A vacuum cleaner is described having a suction unit, a first cleaning tool, and a second cleaning tool. The first cleaning tool is attachable to the suction unit and includes a first dirt separator. The second cleaning tool is likewise attachable to the suction unit and includes a second dirt separator. The first dirt separator and the second dirt separator employ different mechanisms for separating dirt from an airflow.

A hand vacuum cleaner has an upper end, a lower end, an air flow passage, a main body with a handle, an air treatment member, an on board energy storage member, and a suction motor. The on board energy storage member is positioned in the air flow passage downstream of the air treatment member. The suction motor is provided in the air flow passage downstream of the energy storage member.

In general, the present disclosure is directed to a hand-held surface cleaning device that includes a relatively compact form-factor to allow users to store the same in a nearby location (e.g., in a drawer, in an associated charging dock, on a table top) for easy access to perform relatively small cleaning tasks that would otherwise require retrieving a full-size vacuum from storage. A hand-held surface cleaning device consistent with aspects of the present disclosure includes a body (or body portion) with a motor, power source and dust cup disposed therein. The body portion also functions as a handgrip to allow the hand-held surface cleaning device to be operated by one hand, for example.

A cleaning apparatus includes a cleaner including a dust container in which contaminants are collected and a dust container cover rotatably coupled to the dust container to open or close the dust container, and a docking station on which the cleaner is detachably mounted, the docking station including a collecting portion to collect the contaminants in the dust container in response to the mounting and a duct portion forming a channel to guide the contaminants in the dust container to the collecting portion in response to the mounting; a cover opening device configured to open the dust container cover, and a cover closing device configured to close the dust container cover, the cover closing device including a rotary lever configured to be movable between a first position forming a portion of the channel of the duct portion and a second position supporting the dust container cover in a closing direction.
