This vacuum cleaner is great for crumbs and small debris. On my machine it works without running the car. The suction power is good. It's not as good as a car wash vacuum, but it's not as bad. It's definitely a lot easier than lugging a vacuum cleaner out of the house and then looking for a cord to reach it. I see it more like a maintenance vacuum than a deep clean. You can't just use it to detail your car. Attachments work fine. When you're done, it's easy to shake out the dirt. Everything fits into a handy little bag when you're done. Overall this is a decent vacuum, especially if you have kids.
