This is a handy little machine.  I have become a fanatic about dust or dirt on the floor and find myself using this little machine often!  I feel that I can keep up on my housework, with two little kids, a lot easier with this tool.
I wish it had a bit more suctioning power as it doesn't work as well on the carpet in my car as it does inside my home on the hardwood floors.  Regardless, it was definately worth the purchase!
