Disclosed is a vacuum cleaner with a drum brush. The vacuum cleaner includes: a cleaner body configured to generate suction power; and a foreign object suctionor configured to suck foreign objects by the suction power. The foreign object suctionor includes a cylindrical drum brush and a drum support configured to house a part of the drum brush and rotatably support the drum brush. The drum support includes a drum housing part configured to have a shape corresponding to an outer circumferential surface of the housed drum brush, a scraper configured to be provided in the drum housing part to remove foreign objects attached to the drum brush, and a foreign object stopper configured to be provided in one area of the drum housing part at a predetermined inflow blocking distance along a rotation direction of the drum brush from the scraper. As a result, the vacuum cleaner may effectively prevent the drum brush and the scraper from being abraded or damaged by rotating with the drum brush without removing certain foreign objects.

A vacuum cleaner includes a main body including a fan, a motor connected to the fan, and configured to rotate the fan to generate an intake force, and an intake head connected to the main body to guide foreign substances to be drawn into the main body therethrough by the intake force. The intake head includes a housing including an inlet, a drum brush rotatable within the housing to allow the foreign substances to be drawn into the housing through the inlet, and the drum brush including a drum body and a brush on an outer circumference of the drum body, and a cutter adjacent to the brush and including a plurality of cutting edges arranged along an axial direction of the drum brush to allow the foreign substances wound on the drum brush to be cut and removed from the drum brush.

The present disclosure discloses a roller brush, a floor brush head, a brush bristle structure, and a vacuum cleaner. The roller brush of the present disclosure includes a roller brush substrate, at least one group of first cleaning slots arranged in group are formed in the roller brush substrate, the number of first cleaning slots in each group arranged in group is at least three, and the first cleaning slots in each group are close to one another. Actions of the cleaning members do not interfere with one another, especially, during surface cleaning for a carpet and the like, dust scrabbled by the first cleaning member in one group can be effectively scraped away by the second cleaning member arranged in the same group and close to the first cleaning member and cannot be beaten into the carpet again.

A pet hair comb includes an installation shell body having an air duct, a grooming assembly, and a hair scraping assembly, wherein a relative movement between the hair scraping assembly and the grooming assembly allows the hair scraping assembly to scrape down the pet hair on the grooming assembly, wherein the pet hair comb has an air pressure adjusting port which is configured to be switched between an unblocked sate and a blocked state when the air duct is in a negative pressure state for sucking the pet hair, so as to adjust an air pressure in the air duct for facilitating the removal of the pet hair on the comb.

The present disclosure discloses a roller brush, a floor brush head, a brush bristle structure, and a vacuum cleaner. The roller brush of the present disclosure includes a roller brush substrate, at least one group of first cleaning slots arranged in group are formed in the roller brush substrate, the number of first cleaning slots in each group arranged in group is at least three, and the first cleaning slots in each group are close to one another. Actions of the cleaning members do not interfere with one another, especially, during surface cleaning for a carpet and the like, dust scrabbled by the first cleaning member in one group can be effectively scraped away by the second cleaning member arranged in the same group and close to the first cleaning member and cannot be beaten into the carpet again.

An air blade tool operable as a surface and crevice cleaning tool is provided. The air blade tool includes a housing assembly, blade assembly, and air conduit assembly adapted for mounting to an air blower. The housing assembly includes a housing, a handle, a blade retainer seat, and openings for emitting air. The blade retainer seat may comprise one or more blade supports. The housing assemblies may include a fastener system for releasably securing interchangeable blades at predetermined positions along the length of the housing. The blade assembly includes at least a blade and in some embodiments a blade retainer. The air conduit assembly includes an air conduit and may include a swivel fitting for engagement with an air blower for enabling relative movement of the fitted blower to minimize hindrance of control of the air blade tool during use. The housing assembly may further include a damper within the housing and actuator to control the position of the damper and permit selection of the direction of air flow.

A cleaning device includes a base member extending with a first distal end and a first proximal end. The first proximal end is at an angle relative to the first distal end. A support member extends between a second distal end and a second proximal end. At least one support flange couples the base member and the support member. An extension member extends from the second distal end. At least one teeth member comprises a contact surface and an attachment surface. The attachment surface is formed with an inner channel, and the inner channel is coupled with one of the first distal and proximal ends. The contact surface has outer flanges with an outer channel formed therein. The contact surface is adapted to come in contact with a cleaning surface such that the outer flanges penetrate the cleaning surface to dislodge and collect debris.

In a vacuum cleaner utensil (1) comprising a suction opening (3) and a lint picker (5) at a side of the suction opening (3), the lint picker (5) is mounted in a recessed portion having a plurality of rims (7a-7d) along lines at an angle between 20 and 70 to a longitudinal axis (A-A) of the suction opening (3) that form edges pointing towards the suction opening (3). Preferably, the lint picker has a plurality of triangular-shaped elements (5a-5d). Preferably, the lint picker has a plurality of elements (5a-5d) that have first and second boundaries along lines at an angle between 20 and 70 to the longitudinal axis (A-A) of the suction opening (3), an angle between the first and second boundaries not exceeding 120. Another aspect of the invention provides a vacuum cleaner comprising a suction unit, and a nozzle arranged for being coupled to the suction unit, wherein the nozzle is formed by such a vacuum cleaner utensil (1).

A cleaner comprises a body configured to generate a suction force, a handle including a first manipulation part configured to select a function of the cleaner, an extension pipe detachably coupled to the handle and an accessory assembly configured to be coupled to the handle to clean a cleaning surface. The accessory assembly comprises an accessory body, a dusting tool on which a brush is mounted, a crevice tool to clean a gap, and an Upholstery tool to clean fabrics. The upholstery tool is rotatably coupled to the accessory body, the crevice tool is rotatably coupled to the accessory body so that a suction port of the crevice tool is rotatable with respect to the accessory body, and a central axis of the accessory body is provided to be inclined at a predetermined angle with respect to a rotation axis of the crevice tool.
