The vacuum generation and sound attenuation assembly may include a vacuum source including a plurality of vacuum generators. Each of the plurality of vacuum generators may be positioned to cause a vacuum flow between the source of the material and the vacuum generation and sound attenuation assembly. The vacuum generation and sound attenuation assembly may further include a sound attenuation chamber connected to the vacuum source. The sound attenuation chamber may include an attenuation housing at least partially defining a chamber interior volume being positioned to receive at least a portion of the vacuum flow from the vacuum source and attenuate sound generated by the vacuum source.

Hand held vacuum cleaning apparatus (100) includes an elongate housing (122) which is cylindrical in shape. The housing (122) defines an inlet opening (108), an interior (124) and an exhaust opening (118). The housing (122) further defines, within the interior (124), a receptacle receiving chamber (112) in which, in use, a removable dust retaining receptacle (115) is located. The receptacle receiving chamber (112) is substantially circular in cross section and comprises substantially the whole of the diameter of the interior (124) in cross section. The apparatus (100) includes a flow inducer (117) located in the interior (124). In use, the flow inducer (117) induces air flow from the inlet opening (108), through the receptacle (115) in the chamber (112), through the flow inducer (117) to the exhaust opening (118).

A cleaning robot includes a top cover, a bottom cover provided below the top cover, traveling parts provided in the bottom cover, a suction module provided in the bottom cover to suck in foreign materials on the ground, a recessed part firmed to be recessed inward between the top cover and the bottom cover, and a first sensor located in the recessed part.

The present disclosure provides a cleaning method for the water surface of swimming pools and cleaning robot, the cleaning robot comprising a cleaning robot body, a sonar arranged around the cleaning robot body, two rear thrusters located at the tail of cleaning robot body. According to the present disclosure, as long as the cleaning robot body is placed on the water surface of the pool, cleaning robot body floating on the surface of the pool may automatically move and steer, so as to ensure that it can turn in advance before encountering the pool wall and won't knock against the pool wall, reduce the probability of malfunction and damaging of cleaning robot body, and the cleaning robot body can cover the entire water surface of pool and the pool wall, there is no omitting of cleaned water surface, and there is no need for excessive human involvement, it makes it easy for cleaning staffs to clean, when the cleaning robot body cleans the water surface of the pool, the cleaning staffs can carry out other cleaning work, which improved the cleaning efficiency of the cleaning staffs.

The disclosure belongs to the technical field of intelligent household equipment, and provides to a front bumper assembly and a cleaning robot. The front bumper assembly includes a bumper body and two elastic pieces, the two elastic pieces are disposed at the rear ends of two sides of the bumper body, each of the elastic pieces is of an integrally formed structure and is provided with a first elastic portion and a second elastic portion which are abutted against the bumper body, the first elastic portion is configured for receiving first pressure applied by the bumper body, and is able to apply a first counterforce to the bumper body, the second elastic portion is configured for receiving a second pressure applied by the bumper body, and is able to apply a second counterforce to the bumper body, the first pressure is a pressure in an advancing direction of the cleaning robot, and the second pressure is a lateral pressure perpendicular to or arranged at an acute angle with the advancing direction. The disclosure further provides a cleaning robot. According to the front bumper assembly and the cleaning robot, the number of needed elastic pieces is small, the occupied space is small, and the manufacturing cost is low.

A cleaning robot includes a housing assembly, a roller brush, a driving module, a dust box, a suction device, a power supply battery and two travelling modules. The housing assembly has a front end and a rear end, and a bottom of the housing assembly is recessed to form a mounting cavity. The roller brush is rotatably arranged in the mounting cavity and can be driven to rotate by the driving module. The two travelling modules are arranged at the rear end of the housing assembly and are spaced from the roller brush in a front-rear direction of the housing assembly.

An AI apparatus and an operating method are provided, the AI apparatus includes a communication interface to receive 3D sensor data and bumper sensor data from a first cleaner, a processor to generate surrounding situation map data based on the 3D sensor data and the bumper sensor data, and a learning processor to generate learning data by labeling area classification data for representing whether the surrounding situation map data corresponds to the stuck area, and to train a stuck area classification model based on the learning data. The processor transmits the trained stuck area classification model to a second cleaner through the communication interface.

A cleaning robot includes a housing and a roller brush. The housing is provided with a mounting cavity with an opening at its bottom. The roller brush is rotatably arranged in the mounting cavity and at least part of the roller brush is extended out of the mounting cavity.
