The article is devoted to the urgent problem of the resource increasing of the brush working equipment of a communal machine. To increase the resource of the brush working body, it is necessary to provide the recommended area of the contact spot of the brush bristles with the surface to be cleaned. This can be done by using a brush position control device. The results of the study of the effect of bristles deformation on the area of contact between the brush working equipment and the surface being cleaned are presented. A variant of the position controlling device of the brush working equipment of a communal machine providing the recommended area of the contact spot between the bristles and the surface being cleaned is proposed. A design diagram of the deformation of the brush working body is presented. As a result of the interaction process analysis between the brush working equipment and the surface being cleaned a relationship is obtained connecting the area of the contact spot with the deformation of the pile. A graph of this dependence is constructed. As a result of the work performed, a relationship is determined that allowing to determine the value of the contact area of the brush working equipment with the surface being cleaned for various values of the bristles deformation taking into account their wear.
