Abstract: Provided are a floor brush assembly for a vacuum cleaner and the vacuum cleaner. The floor brush assembly includes a roller brush component and a driving mechanism. The roller brush component includes a sleeve and a roller brush body rotatably mounted in the sleeve. The roller brush body is provided with bristles. The driving mechanism includes a power source and a transmission component. The transmission component includes a first driving member, a second driving member, and a driving wheel connected to the power source. The driving wheel is connected to the first driving member through a transmission shaft to drive the roller brush body to rotate. The driving wheel is connected to the second driving member through a linkage structure to drive the sleeve to rotate. The first driving member and the second driving member are eccentrically arranged to allow the bristles to be selectively extended out of or retracted into the sleeve.

Abstract: Provided is a floor brush assembly for a vacuum cleaner. The floor brush assembly includes a roller brush component and a driving mechanism. A roller brush body of the roller brush component is rotatably mounted in a sleeve. The roller brush body is provided with bristles arranged in an elongated shape to form a bristle portion. The sleeve of the roller brush component has an avoidance opening of an elongated shape, and the bristle portion and the avoidance opening are arranged to directly face towards each other in a radial direction of the roller brush body. A first driving member of the driving mechanism is configured to drive the roller brush body to rotate, and a second driving member is configured to drive the sleeve to rotate. The first driving member and the second driving member are eccentrically arranged to allow the bristle portion to be selectively extended or retracted through the avoidance opening.

Abstract: Provided are a cutting apparatus, a cleaning device, a cleaning base station, a cleaning system, and a method. The cutting apparatus includes a housing, N groups of blades, and a drive mechanism. The housing has an opening. N groups of blades each include a fixed blade and a movable blade. N fixed blades are located in the housing and arranged linearly. N movable blades are located in the housing and arranged linearly. Each of the N movable blades corresponds to one of the N fixed blades. Each of the N fixed blades and each of the N movable blades have a toothed edge protruding from the opening towards an outer side of the housing, and the toothed edge of the fixed blade is tightly fitted to the toothed edge of the movable blade.

Abstract: Provided are a floor material identification method, system and device, and a storage medium. The floor material identification method the floor material identification method includes: acquiring a vibration signal generated by a cleaning robot when operating on a floor of a material of a plurality of materials; determining at least one identification parameter for floor material identification based on the vibration signal; and identifying a floor material type based on the at least one identification parameter. Floor materials are distinguished by characteristics of different vibration signals from the floor of different materials, and thus problems such as high cost, low reliability and inaccurate identification result of the existing floor material identification method can be solved.

Abstract: Provided are a fan assembly and a vacuum cleaner having same. The fan assembly includes a housing, an impeller assembly, and a driving member. At least part of the impeller assembly is accommodated in the housing. The impeller assembly includes a plurality of impellers connected in series in an airflow flowing direction of the fan assembly. The driving member is configured to drive the plurality of impellers to rotate.
