I owned another central vacuum cleaner that had much more suction. The brush rotated fast and did not stop when I let it rest on the carpet. This unit does not have enough power to keep the brush rotating, which is very frustrating. (MD NOTES: For air driven brushes use our S44 or S5 models, you will be thoroughly impressed.)
Very disappointing as the motor lasted only 6 years. I paid $1,000 for it in 2000 and had expected it to last longer. We use it only twice each week.
