A:Answer Aside from some design differences, the RS Pro UV+ utilizes our latest in handheld innovation, Steamless Heat Technology. The hot air blower on the bottom of the unit emits heat at nearly 150°F to eliminate live dust mites. Both units feature our RayClean Technology™ which includes HEPA filtration, our UV lamp to kill viruses and bacteria, UltraPulse brushes, and carefully calibrated suction. The major difference is the Steamless Heat that only the RS Pro UV+ has.
