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.

An agitator for a vacuum cleaner includes an agitator body and a resiliently deformable flap. The resiliently deformable flap includes a front face, a rear face, and one or more protrusions extending outwardly from the front face. An agitator for a vacuum cleaner includes an agitator body and a bristle strip and/or a plurality of tufts arranged in one or more rows along the agitator body. The bristle strip and/or a plurality of tufts includes a first bristle group including a plurality of nylon bristles and at least a second bristle group including a plurality of para-aramid bristles.

A cleaning head for a vacuum cleaner includes a brushroll chamber and defining an air path, an inlet into the brushroll chamber, and dual counterrotating brushrolls mounted in the brushroll chamber. The brushrolls have sets of tines that are timed to interfere with each other as the brushrolls rotate to pull pet hair and other debris into the air path.

A cleaning module includes: a first rolling brush including first brushes; and a second rolling brush arranged substantially side by side with the first rolling brush and including second brushes, wherein when the first rolling brush and the second rolling brush rotate, a first outer contour formed by a trajectory of outer ends of the first brushes and a second outer contour formed by a trajectory of outer ends of the second brushes at least partially interfere with each other, and the first brushes are not in contact with the second brushes.

An autonomous cleaning robot (e.g., an autonomous vacuum) may use a sensor system to map an environment that may be used to determine where to clean. The autonomous vacuum receives visual data about the environment and determines a ground plane of the environment based on the visual data. The autonomous vacuum detects objects within the environment based on the ground plane. For each object, the autonomous vacuum segments a three-dimensional (3D) representation of the object out of the visual data and determines whether the object is static or dynamic. The autonomous vacuum adds static objects to a long-term level of a map of the environment and dynamic objects to an intermediate level of the map. The autonomous vacuum may further add virtual borders, flags, walls, and messes to the map.

A rotatable agitator is used in a surface clearing head of a surface cleaning apparatus. The agitator is coupled to the cleaning head at least partially within an agitator chamber and is rotated about a pivot axis. The agitator includes an elongated agitator body and a hair migration portion. The hair migration portion includes a continuous row of bristles and a sidewall. The continuous row of bristles and sidewall are at least partially revolved around and extend along at least a portion of the pivot axis from one of a collection area or a first end region of the agitator and either another collection area or a second end region of the agitator. The sidewall extends substantially parallel to the continuous row of bristles within the hair migration portion. The continuous row of bristles and sidewall are configured to reduce hair from becoming entangled in the bristles and to migrate hair towards the collection area or the first end region of the agitator.

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.

A cleaner head for a vacuum cleaning appliance, the cleaner head including a main body supporting an agitator. The agitator includes a rotatable cylindrical body that bears an elongate agitator formation for engaging a floor surface as the cylindrical body rotates. The elongate agitator formation includes a first agitator row extending around the cylindrical body from a respective first edge L of the cylindrical body towards its centre C in a first helical direction and a second agitator row extending around the cylindrical body from a respective second edge R of the cylindrical body towards its centre C in a second helical direction that is counter to the first helical direction, wherein the first agitator row includes agitators of a first material and wherein the second agitator row includes agitators of a second material that is different to the first material.

A vacuum cleaner includes a main body and a suction nozzle. The suction nozzle includes a housing, a driver, a rotating brush, and a detachable cover. A pressing button is mounted in the housing. The detachable cover is rotated about the rotational axis of the rotating brush to be mounted in the housing. The pressing button selectively blocks rotation of the detachable cover.

Disclosed solutions relate to cleaning devices for medical devices. For example, a cleaning device for cleaning a channel of a medical device includes a rod. The cleaning device further includes a connector at a proximal end of the rod. The cleaning device further includes a flexible cleaner positioned around the rod. The cleaning device further includes a ferrule configured to removably connect with the connector. The cleaning device further includes a pull member connected to the ferrule.
