I just purchase the vacuum and charge it for 3 day and I get it for clean my car . the suction be great at first and it completely die after 10 minute . it take I about 15 minute to clean my car and that say my car be almost spotless and just have to pick-up small crumb and I just barley have enough time to finish my car before before the vacuum die . there be a black and decker vacuum for automobile and you can plug it into the cigeratte lighter . the Model #pav -1200 W. if you have a semi-dirty carpet in you car you will not be able to finish it . they should have one that work off of electricity and then you could use a adapter in you cigeratte light to make it work . but the battery life be bad and I send mine back asap . bye the way my car be a Taurus . do not buy
