A debris monitoring system includes a receptacle, a first and a second emitter, and a first receiver. The receptacle defines an opening to receive debris into the receptacle. The first and second emitter are each arranged to emit a signal across at least a portion of the opening. The first receiver is proximate to the first emitter to receive reflections of the signal emitted by the first emitter, and the first receiver is disposed toward the opening to receive an unreflected portion of the signal emitted by the second emitter across at least a portion of the opening.

A hand vacuum cleaner comprises a cyclone and a dirt chamber external to the cyclone. The cyclone comprises a dirt outlet in communication with the dirt chamber, a cyclone chamber rear end that is axially spaced from and opposed to a cyclone chamber front end and a sidewall located between the cyclone chamber front end and the cyclone chamber rear end. The cyclone air inlet and the cyclone air outlet are located at the cyclone chamber rear end wherein, when the upper end of the hand vacuum cleaner is positioned above the lower end of the hand vacuum cleaner, the central longitudinally extending axis is oriented generally horizontally. A plate is positioned at the front end of the cyclone chamber. The dirt outlet comprises a gap that is provided at the cyclone chamber front end and the gap is provided at a location that is spaced axially inwardly towards the cyclone chamber rear end.

A hand vacuum cleaner has an air treatment member positioned in an air flow path through the hand vacuum cleaner. The air treatment member comprises an air treatment chamber and a dirt collection chamber exterior to the air treatment chamber. The air treatment member comprises a stationary portion and an openable portion, the openable portion comprises a portion of a sidewall of the air treatment chamber and the openable portion is moveably mounted by a mount between a closed position in which the air treatment chamber and the dirt collection chamber are closed and an open position in which the air treatment chamber and the dirt collection chamber are open. When the inlet conduit extends generally horizontally, the dirt collection chamber underlies the air treatment chamber.

A cleaner includes: a suction motor that generates suction force; a dust separation unit that separates dust from air sucked by the suction force; a motor housing that covers the suction motor; a flow guide that surrounds an outer side of the motor housing and guides air discharged from the dust separation unit to the suction motor; and a body that forms an external appearance by surrounding the flow guide and guides air discharged from the suction motor together with the flow guide.

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 has an air flow path extending from a dirty air inlet to a clean air outlet and a suction motor positioned in the air flow path. A cyclone chamber positioned in the air flow path has a cyclone air inlet and a cyclone air outlet. A longitudinally extending battery pack which extend upwardly and forwardly when the upper end of the hand vacuum cleaner is positioned above the lower end of the hand vacuum cleaner. A portion of the dirt collection region is located below a portion of the battery pack.

A system, method, and a physical figure for presenting user progress in a virtual space are disclosed. The presented user progress may indicate user advancements in the virtual space and/or user development in the real-world. Based on information indicating such user progress, character representation may be determined to reflect the user progress for presentation on the physical figure. In some implementations, specific location(s) on the physical figure may be determined for presenting specific aspect(s) of user progress in the virtual space. The physical figure may receive the determined character representation information and present the character represent on one or more screens thereon.

A cleaner includes: a main body that has an opening; a suction motor that is disposed in the main body and generates suction force; and a filter unit that includes an exhaust filter for filtering air discharged from the suction motor, the filter unit being inserted into the main body through the opening and being separated from the main body, wherein when the filter unit is combined with the main body, a portion of the filter unit protrudes out of the main body, and a portion of the exhaust filter is positioned inside the main body and the other portion of the exhaust filter is positioned outside the main body.

A vacuum cleaner includes an air treatment or debris removable assembly with a multi-layer filtration stage. The multi-layer filtration stage can include an outer mesh screen, a louvered exhaust grill, and a multi-layer filter. Optionally, an inner perforated exhaust grill is also provided. The debris removable assembly can further include a cyclonic filtration stage.
