Let me first say, I'm a car care fanatic. I had to replace my old Black and Decker 12V Vac that I first received as a gift with my first car 13 years ago.This Armor All Vac is fantastic in every way. High quality construction, nice storage bag, super easy to use and clean, plus it has a cool narrow/long attachment for hard to get areas (between and under seats). To clean, top pops off, you have a filter you can remove, plus an internal catch basin to dump debris. I just finished using it for the first time, it did an excellent job. The catch basin and filter had alot of dirt in them, and the car wasn't all that dirty. As with all 12V vacs, the power is pretty low, so you do have to go over the area a few times, since it doesnt have the power of the huge gas station vacs. However, I would absolutely recommend. Very happy with my purchase. The interior actually looks detailed. You can't beat the convenience of having your own car vac, its a definite buy. TIP: In the instruction manual, it says NOT to run your engine when using the vac. It claims it will decrease the life of the vac, assuming from too much power. Personally Ive vaccumed both ways, with engine on and off. Doesnt really seem to make a difference either way. To use with engine off, just plug it in with the engine off, and turn your key to the accessory ON position. Your car's battery will not be affected by using the vac with engine off for a half hour.
