Abstract
A cleaning appliance includes a housing with a brushroll and a wheel mounted thereto. A floor-type sensor is disposed within a mounting tube secured to the housing. The floor-type sensor emits sonic energy toward a surface being traversed by the cleaning appliance and receives corresponding sonic energy reflected by the surface. A comparator, electrically coupled to the floor-type sensor, compares the received reflected sonic energy to one or more associated predetermined values to determine the type of surface being traversed. A processor analyzes the results of the comparison and controls at least one of a suction fan, said wheel and said brushroll, based at least in part on the analysis.
