We have been using a Black and Decker model PAV1200 12v plug in hand held automobile vacuum for about 4 years. It's available on Amazon. It has worked well for us. Only complaint is the bin that collects the dirt is a little small but easy to empty. It has two filters I. It. One is plastic and the other is a replaceable pleated paper filter similar to an automotive air filter.
