I buy this little vacuum for my brand new car , and I have be quite pleased with it . a lot of people on here be compare the suction power to something more powerful , like a Shop-Vac , and that be a little unfair -lrb- this thing be only use a 12volt power source after all -rrb- . also , you be suppose to free up the vacuum 's filter every once and awhile by turn the dial on the side of the unit , and that help tremendously . this be great for people who simply want to keep they car clean - it be not mean for heavy-duty application .
