I couldn't try out my new vacuum cleaner until I assembled it, which took about 40 mins. I find it hard to push even when the rotating brush is set to "high",and my carpet at home has a relatively short nap.
There was no way to test the floor model in the store because there is no demonstration carpet in the vacuum cleaner department. I hope the maid, who comes every other week, won't refuse to use it.
If she does, you'll be hearing from me. The vacuum I bought is the Kenmore Intuition which was rated as a "Best Buy" by consumer Reports.
