DESC: The Bosch Formula Vacuum is one of the quietest vacuums in its class. But while its hushed operation is impressive, advanced features like HEPA filtration, a 11" electric brush and 1400 watts of cleaning power ensure that you'll enjoy the superior performance you expect from a product with our name on it. Meanwhile, convenient touches like its Ergogrip Plus™ handle and an integrated power switch and carry handle design make the formula a joy to use.
