Very disappointed with this compact Vac 'N Blo and had to return it after first use, can't fill an entire small pickup truck cabin interior or small space without overheating. So originally got 1 star. Update January 26, 2019 :: On July 1, 2016, after getting really frustrated with the problem of overheating too quickly when buying the Auto Vac N Blo, Revain kept the vacuum cleaner instead of sending it back, and contacted the manufacturer via email. Mail and ordered replacement carbon brushes.
