The invention relates to a cleaning device for environmental protection, in particular to an electric brush foot pad which can automatically clean the dust, scraps and attached dirt on soles. By adopting the product, the hygienic and environmental protection problems of indoor public places such as factories, hotels, large supermarkets, office buildings, airports, markets and the like, and families can be solved. The main application of the product is as follows: the product is arranged at the inlets of the areas to be cleaned, and when a person steps on the product and passes by, the product can automatically clean the soles to avoid the carrying-in of the dirt. The basic structures of the product comprise a human body supporting framework, a brush mechanism, a transmission mechanism and an electric motor. A brush embedded in the brush mechanism is slightly higher than the upper surface of the human body supporting framework; and when the person steps on the human body supporting framework, the brush mechanism is driven by the transmission mechanism to perform rapid linear reciprocating movement to clean the soles fast, and the dirt such as dust, scraps and the like fall into a bottom dust collection box.
