I used this machine one time and the belt broke! This was due to the spindle that spins the roller belt gets so hot (and stays hot) it actually melted the belt after shutting off the vacuum! The second time I used the vacuum, I noticed it wasn't picking up anything, and the roller brush wasn't spinning. Upon removing the bottom plate, I discovered the problem with the belt. If Dirt Devil gets there act together and fixes this problem, it is actually a very good machine. But the problem with the overheated spindle burning the drive belt, makes this product unusable!
