The difference between this embodiment and the first, second, third and fourth embodiments is that the floor scrubbing robot 100 further includes an inductor for collecting the cleanliness of the floor and a controller electrically connected to the inductor, and the controller is electrically connected to the power unit 31 for controlling the power unit 31 to operate. The sensor and the controller are arranged, so that the dirt degree of the ground can be collected more accurately, the power component can be driven more efficiently, and the ground can be thoroughly cleaned on the premise of lower energy consumption.
The sensor is a photoelectric sensor or an image sensor. The sensor is mounted on the floor scrubbing assembly 20 or the main body 10 to sense the degree of soil on the floor by photographing or otherwise. The specific working process is as follows: the sensor senses the dirt degree of the ground, transmits photoelectric signals or photographed pictures to the controller, the controller is internally provided with software and an algorithm, the dirt cleaning characteristics of the ground are judged according to the photoelectric signals or the photographed pictures, the type and range of the dirt are deduced, then the controller adjusts a friction force set value set under the condition, the power component 31 can adjust driving parameters according to the friction force set value to conduct fixed-point special cleaning, the area can be repeatedly cleaned before and after the cleaning is judged until the cleaning is finished, then the normal friction force set value is transferred, the power component 31 is reset, and therefore other areas with normal dirt degree are cleaned, and therefore the ground is thoroughly cleaned on the premise of low energy consumption. The controller may also set the angle at which the power member 31 rotates to control the degree of pressurization of the pressure mechanism 30. For example, the controller may control the motor to rotate directly, to reciprocate according to a preset rule, or to rotate at different speeds at different times, etc., which are all within the contemplation of the present invention.
Of course, it will be appreciated that the power member 31 may be manually turned on without the provision of an inductor.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
