Not sure yet. I may have to send it back. Suction is not bad, but only if the power is increased. At normal performance, it's no better than our older and much cheaper model. He was about 5 years old and was losing strength. What I don't like about this model is that you have to switch from normal speed to boot up to turn it off. Also, when cleaning the filter, a very small part comes out, like a small damper, and the part that keeps it in the stick. I was able to put it back in place, but I'm not sure if it's seated correctly as this part isn't shown in the instructions. Given the price difference I expected better. In hindsight, I probably should have just ordered a new one, exactly the same as the old $39 model. If a small part comes out again, it comes back. The photo shows the part I mean. It seems that this is some kind of small door to keep dust out of the side.
