Bosch has recently released its new "Airsweep" 13 Gallon Wet/Dry Vacuum Cleaner with Pulse-Clean Electromagnetic filter-cleaning system. The system has elevated dual filter cartridges which are shaken to remove dust, while maintaining maximum suction power. This feature can be activated maunally or automatically- great for when you're working far from the unit, like when working on a scaffold. With 4 different modes of operation, activation by attached power tool, extremely thorough fine-dust filtration capabilities (which capture 99.93% particles of 3.0 microns and larger), large wheels, locking front casters, and a 6.5 HP / 11.1-amp motor with soft-start and bypass cooling , this vacuum is an excellent tool to have around for any project.
Bosch's new Airsweep wet/dry vacuum, model 3931, retails for $399 (list $549).
