Bosch 3931A, 13 gallon Airsweep Wet / Dry vacuum uses Bosch's exclusive Pulse-Clean(tm) Electromagnetic filter cleaning system to shakes the dual filter cartridges and thereby removing dust and maintaining maximum suction power
Elevated filter location means the filters sit above maximum dust or water accumulation height to help maintain maximum airflow and suction power
Pulse-Clean can be activated manually, or automatically, when a connected power tool is switched off (a helpful remote control, such as when working on a scaffold)
Activation by power tool
This feature is for use with power tools with amp ratings up to 7.2 Amps
7-second run-on after power tool is turned off clears hose of remaining debris
4 modes of operation: Regular vacuum, Power Tool activation, Pulse-Clean(tm), Pulse-Clean(tm) with Power Tool activation add to give maximum vacuuming versatility
Large wheels, locking front casters, and easily-removable push handle equal easy transportation
