A filter bag configured for use in a vacuum cleaner is provided. The filter bag includes a first layer of filter material with a selected value of efficiency in removing airborne particulates, and a second layer that is impregnated with silver or a silver compound with antimicrobial properties.

A self-propelled, dust-collecting robot includes a main-body part including a dust collection box, and a first battery pack, which has a case, at least one battery cell in the case, a control circuit board having a controller mounted in the case, and a discharge terminal. The main body part includes a first battery pack mount having a connector to which the first battery pack is removably connectable. The first battery pack is configured for use in an electric power tool.

A disassembly mechanism configured to be disposed on a dust collector is provided, including: a fixation assembly, including a first fixation portion and a second fixation portion, the first and second fixation portions being configured to be disposed on a base and a barrel of the dust collector respectively, the second fixation portion including a slot; an actuating mechanism, including an engaging portion being disengageably engaged laterally with the slot and a connecting portion being movably disposed on the first fixation portion, and the engaging portion being movable with the second fixation portion. A dust collector including at least one aforementioned disassembly mechanism is also provided.

The invention comprises a retaining plate (1), comprising a first plate (2) and a second plate (3) arranged in a first plane, and a third plate (8) arranged in a second plane which runs in parallel to the first plane, the third plate (8) having a lower flexural stiffness than the first plate (2) and the second plate (3), wherein the first plate (2) and the second plate (3) are interconnected by means of the third plate (8) such that a hinge is formed between the first plate (2) and the second plate (3) about the hinge axis (A) of which the first plate (2) and/or the second plate (3) can be bent together with the respective part of the third plate (8) connected thereto.

An allergen reduction device may include a body, a dust cup removably coupled to the body, a plurality of agitators rotatably coupled to the body and disposed within respective agitator cavities defined in the body, a suction motor disposed within the body and configured to cause air to flow along corresponding cleaning airflow paths from the agitator cavities into the dust cup, a hot air outlet fluidly coupled to the suction motor, the suction motor being configured to urge the air through the hot air outlet along a heated exhaust airflow path, and a heater positioned within the heated exhaust airflow path between the suction motor and the hot air outlet, the heater being configured to heat the air that is urged from the hot air outlet.

A self-moving cleaning device includes: a base; a mobile module adjacent to the base and configured to contact a surface when the self-moving cleaning device moves on the surface; a vacuum module arranged over the base; a dust box arranged over the base and connected to the vacuum module, the dust box including a first opening and a second opening; a first suction port arranged on the base and including a first suction inlet connected to the first opening; a second suction port arranged on the base and including a second suction inlet connected to the second opening, the first suction port disposed between a front side of the base and the second suction port; a roller brush device arranged on the base and within the second suction port; and an air duct, wherein the first suction port is connected to the dust box through the air duct to thereby connect the first suction inlet to the first opening.

Described herein is a vacuum device. In various embodiments, the vacuum device includes a vacuum housing; a motor housing coupled to the vacuum housing; a motor disposed in the motor housing and configured to apply suction toward the vacuum housing; an inlet nozzle releasably coupled to a side of the vacuum housing and configured to receive a waste material; and a disposable vacuum bag disposed in the vacuum housing and configured to receive the waste material that passes through the inlet nozzle.
