A robotic dust collector includes: a cover plate that closes an opening of a housing; a first hinge member connected to the cover plate and having an insertion space; an elastic member disposed in the insertion space; and a second hinge member. The second hinge member includes a shaft part that is inserted in the insertion space and supports the elastic member. The second hinge member further includes a fixture part fixed to at least a part of the housing. The second hinge member supports the first hinge member in a manner that allows the first hinge member to rotate about a rotation axis.

A vacuum machine comprising: a housing for receiving vacuumed matter and at least two removably attachable accessories; sensing means for detecting the accessories; a control circuit communicatively coupled with the sensing means; the sensing means being arranged to generate a first signal to the control circuit representative of the presence of a first accessory, a second signal representative of the presence of two accessories, the control circuit being arranged to preventing operation of the vacuum machine when the first signal is received and to allow operation of the vacuum machine when the second signal.

Techniques regarding vacuum bags are provided. For example, one or more embodiments described herein can comprise a vacuum bag comprising a spunbond meltblown spunbond (SMS) liner layer adhered to a carrier layer of non-woven material. The vacuum bag can also comprise a seam comprising an adhesive layer bonding a first end of the carrier layer directly to a second end of the carrier layer.

A vacuum cleaner assembly configured to be mounted in a vehicle. The vacuum cleaner assembly including a vacuum unit configured to draw a vacuum, a canister assembly configured to collect debris and coupled to the vacuum unit, a hose junction configured to serve as a pathway for debris, and a chassis connecting the hose junction to the canister assembly. A pathway through the vacuum cleaner assembly may turn 180 degrees in the hose junction. A dirty air port of the canister assembly may be disposed at an angle relative to a surface of the chassis to facilitate placement and removal of the canister assembly.

In order to accomplish a solution task of the present disclosure, a cleaner hand according to an embodiment of the present disclosure may include a pipe configured to transfer at least one of air, dust, and foreign matter to a drive unit that generates a suction force, a grip portion connected to the pipe, and formed to be gripped by a user, a sensor unit disposed in the grip portion to sense information related to whether or not the grip portion is gripped by the user, and a controller configured to control the drive unit based on the sensed information.

Method for operating a dirt collecting device for a sweeping vehicle or for a vacuum cleaner nozzle of a floor or upright vacuum cleaner, which each comprise a suction fan with controllable speed and/or power, wherein in a first method step, the suction power of the suction fan is set at such a low level that the suction pressure in the dirt collecting device or the vacuum cleaner nozzle is merely sufficient to convey and deposit the absorbed coarse dirt into the intermediate container, and to convey the absorbed fine dirt into a downstream collection container, (normal operation); and that in a second method step, the filling level in the intermediate container is detected with respect to the coarse dirt deposited therein; and that in a third method step, if the filling level in the intermediate container is exceeded, the suction power of the suction fan is increased such that the coarse dirt, which is temporarily deposited in the intermediate container, becomes dispersible and is conveyed into the downstream collection container (emptying mode).

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.
