The present disclosure discloses a cleaning strip, a roller brush body and a vacuum cleaner. The roller brush body of the present application can be used for cleaning a carpet and the like, cleaning protrusions can extend into the carpet to fully dig up hair in the carpet, meanwhile, each notch is formed between every two cleaning protrusions, the cleaning protrusions have certain flexibility, and thus the carpet can be prevented from being damaged and deformed due to pressing during a cleaning process. In the present application, only a cleaning element needs to be arranged on the roller brush body, is capable of extending into the carpet for cleaning, a user does not need to replace different roller brushes according to different ground surfaces, and machining cost of a roller brush is lower.

A brush bar including a central core in the form of a rigid tube, a plurality of outwardly extending bristles in the form of at least one bristle strip, and a sealing material extending over substantially the entire remaining circumferential and axial extent of the brush bar, the at least one bristle strip having a root portion which is sandwiched between the sealing material and the central core or which is attached on top of the sealing material.

An electric cleaning brush using a bristle brush for cleaning is provided, which relates to the technical field of electric cleaning brushes. The electric cleaning brush includes a brush head, a spinning driving assembly, and a brush main body. The brush head is rotatably arranged on the brush main body. The spinning driving assembly is configured to drive the brush head to spin. The brush head includes a shaft-like connector. A bristle connecting portion is arranged on an outer side of the connector. The bristle connecting portion is connected with a plurality of bristles. The bristle connecting portion is configured to clamp and connect bristles in a clamping manner, so that the bristles can be better maintained on the brush head and are not likely to be disconnected. In addition, the bristles have bent cleaning portions that can correspondingly enlarge a cleaning range during spinning.

A material treatment device intended for use for human or animal hair includes a plurality of rods arranged circumferentially as part of a rod barrel and a handle attached to the rod barrel for rotatable support thereof. A mechanism is provided to rotate the rod barrel in a first direction and a second mechanism is provided to rotate each of the rods separately from the rod barrel in a second direction opposite the first direction. The material being contacted by the rods during use of the hair treatment device rolls away from the contacted rod in the second direction or permitting each of the rods to freely spin during rod barrel rotation. The device can also include bristles that move with respect to the rod barrel or are fixed thereto, the bristles moving with the rod barrel rotation.

The present disclosure provides a locomotion apparatus used in liquid. The moving apparatus includes a buoyancy cavity disposed in the locomotion apparatus, and is configured to accommodate gas or liquid; and a first regulation part disposed in the locomotion apparatus, and is configured to regulate a volume of the gas or the liquid in the buoyancy cavity; when the locomotion apparatus is switched from the sidewall of a swimming pool to the liquid surface, the volume of the gas or the liquid in the buoyancy cavity is regulated by the first regulation part to increase the buoyancy force applied to the locomotion apparatus.

The present disclosure provides a cleaning device, including: a cleaning device body; a filtering mechanism; a cleaning cavity disposed at a front portion of the cleaning device body and configured to accommodate at least one first cleaning part; a liquid inlet portion; a mode switching member configured to adjust a pose of the cleaning device, enabling the cleaning device to be switched between a first motion state and a third motion state, where when the cleaning device is in the first motion state, the liquid inlet portion is located under a water surface, and the cleaning device performs underwater cleaning, and when the cleaning device is in the third motion state, the liquid inlet portion is at least partially located above the water surface, and the cleaning device performs water surface cleaning; and a main water pump configured to generate a suction force.

A pendulum rocker brush for a vehicle wash system is provided including a rocker arm, a rotatable coupler, a motor assembly, and a rocker brush head. Both the rocker brush head and motor assembly can be suspended from the coupler, freely dangling therefrom under the force of gravity, in an unbiased manner. The rocker brush head can pivot relative to the rocker arm through a swing angle between 5 and 45 degrees relative to vertical. The rotatable coupler and rocker brush head can be disposed at a pivoting angle between 10 and 45 degrees relative to a conveyor direction which a vehicle follows. When the rocker brush head encounters an opposing force above a movement threshold from the vehicle, the rocker brush head and the motor assembly can swing outward to the swing angle and at the pivoting angle so the vehicle is not damaged.

A method for manufacturing a cylindrical brush of a cleaning tool, comprises a cylindrical brush having a core member, a plurality of rail plates, a plurality of polyvinyl alcohol (PVA) nodule foam bars and a pair of end caps. The core member includes an outer wall having a plurality of core holes and a pair of openings. The plurality of rail plates having a plurality of rail holes arranged along the outer wall of the core member. The plurality of polyvinyl alcohol (PVA) nodule foam bars is installed at each of the plurality of rail plates such that each of a plurality of nodules of the PVA nodule foam bar aligns with the plurality of core holes and with the plurality of rail holes. The pair of end caps encloses the pair of openings of the core member.
