is worth the price. I bought this device because it is lightweight and comes with two removable batteries. That's the only positive thing about this device. The swivel head of the brush doesn't allow you to stay straight. If you try to suckle in a straight line, he'll move from side to side. When you vacuum hairs longer than 1-2 inches, they will wrap around the brush roll. You must clean the roller after each use. It works well on hardwood and tile. This will not work on ANY type of carpet. All in all this was a disappointing purchase and will be returned. I am shocked that they are charging $215-$400 for this device. I don't think it's worth $100.
