The Bosch Formula Vacuum is by far the quietest vacuum in its class. But while its hushed operation is impressive, advanced features like HEPA filtration, a 12" 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, it's award winning modern design offers convenient touches like an Ergogrip Plus handle and an integrated power switch/carry handle, that make the formula a joy to use.
