Abstract
Aspects of the disclosure provided a method to improve performance of a cleaning device to extend a usage life of the cleaning device. The method can include obtaining a performance characteristic of an electrostatic brush that degrades operations of the electrostatic brush, determining at least one parameter that compensates for the degradation, and controlling the electrostatic brush by the at least one parameter to maintain the electrostatic brush operating within a failure boundary.
