The present invention relates to a shop vacuum cleaner cartridge filter rotating system, consisting of a turbine mount, a turbine impeller blade and a cartridge filter mount, assembled on an axle. The suction air stream through the shop vacuum cleaner and through the turbine rotates the cartridge filter on the filter mount of the filter rotating system, creating centrifugal force on the outer surface of the rotating cartridge filter, which inhibits particles carried by the air from settling on the filter. This rotating action of the filter keeps the filter relatively clean, with air passage through the filter unobstructed, which prolongs the optimum function of the filter and reduces the frequency of necessary filter service. The shop vacuum cleaner cartridge filter rotating system can readily be built into a new vacuum cleaner or retrofitted in existing vacuum cleaners.
