Query: Excellent amount of power!

I bought this Dirt Devil based on price and reviews. The ONLY thing wrong with it is that it's a little bit difficult to push, but I'm of smaller stature, so this may not be an issue for others. It's really light, though. Easy to carry around and the suction power of this is phenomenal! It's an amazing vacuum!
