Query: beats the Dust Buster

Great alternative to the standard Black & Decker dust buster. I was reluctant because i had heard about the difficult charging base. Shark solved that by omitting the charging base from the current units. This means you cannot mount this unit on the wall to quickly grab it for use as with a Dust Buster. Otherwise, it does a better job at vacuuming and the power brush is a good addition.
