    摘要： A cleaning method and a cleaning robot are provided. The method includes: after the cleaning robot obtains a cleaning instruction for a target scene, acquiring a current power of the cleaning robot and a scene map for the target scene; if it is determined that the current power is insufficient to clean all areas to be cleaned in the target scene, determining a target cleaning area from all the areas to be cleaned in the target scene, based on a target dirtiness level for each of the areas to be cleaned; cleaning the target cleaning area based on the scene map, the target dirtiness level for the target cleaning area and the current power. A more intelligent cleaning robot and a more reasonable cleaning process are realized.

    摘要： A vacuum cleaner comprising an electric motor, an impeller and an axial diffuser arranged on a common axis is provided. The impeller is connected to the electric motor and is arranged for rotation on the common axis to achieve a radial air flow. The radial air flow is redirected into an axial air flow. The diffuser passages are arranged between an inner circumferential wall and an outer circumferential wall, wherein the walls are coaxially arranged around the common axis. Each diffuser passage is delimited in a circumferential direction between the walls by vanes extending between the inner wall and the outer wall and in an axial direction extending substantially in parallel with the common axis. The vanes are arranged in at least two rows being consecutively arranged in the axial direction extending substantially in parallel with the common axis.

    摘要： A cleaning robot a dirt recognition device thereof and a cleaning method of the robot are disclosed. The recognition device includes an image collecting module and an image processing module. The image collecting module may be used for collecting the image information of the surface to be treated by the cleaning robot and sending the image information to the image processing module. The image processing module may divide the collected image information of the surface to be treated into N blocks, extract the image information of each block and process the image information in order to determine the dirtiest surface to be treated that corresponds to one of the N blocks. Through the solution provided by the present invention, the cleaning robot can make an active recognition to the dirt such as dust, so that it can get into the working area accurately and rapidly.
