Abstract
A device and method for regulating the pressure between a floor cleaning implement () and a floor, wherein the floor cleaning implement () is coupled to a floor cleaning machine (). The device of one embodiment comprises a cantilevered arm () coupled to the floor cleaning machine () and a sensor () coupled to the cantilevered arm () and positioned to sense deflection or other deformation of the cantilevered arm (). An actuator () is coupled between the cantilevered arm () and cleaning implements (). The actuator () is also coupled to the sensor () and adapted to receive signals from the sensor () to cause actuation of the actuator (). When pressure other than a predetermined amount causes the cantilevered arm () to deform, the sensor () senses this deformation and cause the actuator () to actuate in a direction that allows the cantilevered arm () to return to a position in which the pressure is within the predetermined amount.
