This mini vacuum is great for small jobs. The suction power is sufficient to pick up fine gravel. The dirt is sucked into the bowl at the front of the vacuum where it is stored until it is emptied. This little device is perfect for small jobs. And I mean small jobs. This vacuum cleaner is smaller than a portable handheld vacuum cleaner. It can easily fit in your pocket. Due to its size, you will need to empty the cup frequently. Don't expect this little vacuum cleaner to do a thorough cleaning. That's not what he's made for. Ideal for vacuuming up food crumbs from the car seat or fine dirt from the car floor.
