I need a simple car vac that would run off the standard cigarette lighter socket - 12v dc power . live in a condo , I have no access to power where my car be park . I look at the cheaper , more `` Dustbuster '' - style auto vac from black and Decker , and the review be not favorable . I have one of those year ago that be pretty much useless . give this one a try and it be be great . now , you have to be realistic - it be not as good as go to a car wash or gas station and use one of the commercial coin-vac - this be for those in-between time when you want to get the heavy stuff out . dirt on the mat , along the edge , on seat . it be surprisingly powerful , and very versatile . the nozzle rotate in various position for reach in different area -lrb- straight out for the floor , more vertical for in-between seat , etc -rrb- . it also have a upholstery attachment that make it easier to loosen dirt from thicker fabric -lrb- trunk , carpet -rrb- . the attachable hose be great , too , for reach hard-to-get area . Everything store well , too - the cord wrap on a reel build into the unit , the nozzle retract underneath it , and the unit and hose fit into a supply carry case . my only complaint be that the unit tend to -lrb- through static -rrb- attract dirt to its exterior - mostly near the cyclone dust chamber . it can stand to be damp wipe after use . no big deal , though , and it be a good solution for those with 12v power requirement .
