I HATED this machine. HATED it. It did do a good job but it clogged all the time and was hard to clear out. The gill-type filters clogged constantly and the dust had to be dug out with a stick, which was messy and time-consuming. If you see that a machine has this type of tower filter, DO NOT buy it. The filters are expensive to replace so you don't want to just toss them when they get dirty. Unless you vacuum constantly so you never have much dust to deal with, this machine is a huge pain in the neck. I regretted getting rid of my old, bag machine, which was heavy and had a broken handle but at least didn't plug up all the time and wasn't messy to empty. The thing finally clogged for the last time and I threw it away and bought a Shark with a rinse-able filter.
