The Spinduster is suitable for all brands of Central Vacuum Systems. Simply plug the Spinduster into a vacant wall inlet and press the On/Off switch. As the Duster spins it electrostatically charges the nylon brush. Remove the brush and watch dust “fly” and stick to the bristles. Extend the brush handle to reach high cornices etc. When finished dusting place back in the canister and activate the switch. This will clean the brush and recharge for next use.
