Summary: Well this is a mixed review, I like it it has decent power but the power brush gets locked up alot on carpets. I think they even increased the size of the air way improving air flow. 2 things to make this a great buy 18-24 volt li-on battery and a much stronger powered brush, put in a smaller powered brush and have the stick hold everything and 150$ is not a bad max price range for it.
Summary: Really good for the price. Didn't do a good job with the Cheerios unless you go a bit slow and pick it up in the model of the head. Good power and really good battery life. UPDATE The performance of this unit dropped. I think it was because there was hair in the agitator. It also drops with a little debris in the unit. Thus the unit needs to be clean to work well. Even when clean, the suction just is not good enough (in handheld and stick mode).
