A dust collecting apparatus includes a dust separation unit to separate dust from suctioned air; a dust storage unit to store the dust separated in the dust separation unit; a pressing member to compress the dust stored in the dust storage unit, and having a pressing plate support part, and a pressing plate supported by the pressing plate support part; a fixing member disposed between an inner circumferential surface of the dust storage unit and the pressing plate support part; and a path formed by a part of the fixing member, located between the pressing plate support part and the inner circumferential surface of the dust storage unit, and through which the air between the pressing plate and the fixing member passes, wherein one or more holes through which the air between the pressing plate and the fixing member passes are formed at the pressing plate.

A hand vacuum cleaner having a main body and cyclone unit provided at a front end of the main body. The cyclone unit has a front openable door.

A dual cyclonic stage hand vacuum cleaner has a handle provided on a side of the hand vacuum cleaner.

A hand vacuum cleaner having a main body and an air treatment member provided at a front end of the main body.

A robot cleaner includes a body; a driving unit; at least one sensor configured to detect an obstacle; a cleaning unit, the cleaning unit including a brush unit and a fan unit; a dust box to store dust inside of the dust box, the dust box being detachably mounted to the body; and a dust sensing unit including a light emitting unit to transmit light and a light receiving sensor to sense the light transmitted by the light emitting unit, the light emitting unit and the light receiving sensor being fixed on the body and outside of the dust box, and the light emitting unit being configured to transmit light through the inside of the dust box. The driving unit, the at least one sensor, the cleaning unit, the dust box, and the dust sensing unit are positioned on or in the body of the robot cleaner.

A hand vacuum cleaner has a cyclone assembly comprising a first stage cyclone and a second stage cyclone. The first stage cyclone has a first stage cyclone chamber and a first stage dirt collection chamber. The second stage cyclone is downstream from the first stage cyclone and at least partially nested in the first stage cyclone and has a second stage cyclone chamber and a second stage dirt collection chamber. The cyclone assembly has an openable end comprising at least one of the front end and the rear end, the openable end is moveable and closes the first stage cyclone chamber, the first stage dirt collection chamber, the second stage cyclone chamber and the second stage dirt collection chamber.

A hand vacuum cleaner has a cyclone having a cyclone axis of rotation that extends between the front and rear ends of the cyclone. A main body houses a suction motor. The suction motor is positioned rearward of the cyclone. The suction motor has an axis of rotation that is parallel to the cyclone axis of rotation. A pistol grip handle is located at the rear end of the hand vacuum cleaner wherein a finger grip area is positioned forward of the pistol grip handle and rearward of the main body. The cyclone axis of rotation extends through the pistol grip handle. An energy storage unit located at a lower end of the pistol grip handle and a power switch located at an upper end of the pistol grip handle.

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 method of treating a building for mold contamination including the steps of assessing and locating mold growth areas, constructing a containment barrier around the mold growth areas, vacuuming, abrading and surface treating the mold growth areas, ceilings, walls and window treatments with mold cleaner, replacing air filters from air handlers, removing all registers and vent grills in the treated areas and washing the vent grills with mold cleaner, vacuuming all registers and accessible ductwork, treating the heating and ventilation system, associated ductwork and wall cavities with an atomized mold cleaner, vacuuming all flooring, horizontal surfaces, walls, furniture and mattresses, re-vacuuming all flooring, re-treating the heating and ventilation system and associated ductwork with an atomized mold cleaner and re-treating the work area including any exposed wall cavities with an atomized mold cleaner, deconstructing and discarding containment barrier and reinstalling all registers and vent grills.

A stick surface cleaning apparatus comprises a surface cleaning head, which has a dirty air inlet and a surface cleaning head air outlet, and a wand that is moveable between an upright storage position and a reclined in use position. When the wand is mounted to the surface cleaning head and in the upright storage position, the wand has a lower end and an axially spaced apart upper end, a wand axis extending between the lower end and the upper end and a longitudinally extending sidewall, wherein the wand comprises an air treatment member having an air inlet at the lower end of the wand, an air outlet positioned above the air inlet of the air treatment member and a dirt collection region whereby, in operation, dirt separated from air flowing through the wand is collected in the dirt collection region.
