RE: the noise. Well, maybe twin fans does have something to do with it. I am going to guess that the type of metal used in the construction, most likely some kind of pot metal, produces something of an echo chamber making it loud. Also, there is no real insulation around the motor or fan chambers thereby allowing noise to escape. Just a guess.
For the size of the motor, it is very powerful and the RPM's are high judging by the pattern left on the carpet at an average rate of back and forth action during vacuuming. Also, an interesting note, on the beater bar, next to the the actual beaters and the brush strips, I find a fine coating of white powder that I have seen on Hoovers, Air-Way's with the beater bar, (pre-Quiet Series power nozzle), and true beater bar Eureka's.
That white powder, as explained to me a number of years ago, is dead skin cells from humans and pets and really, really fine dust. Sometimes it is slightly tan in color. I've noticed that it only shows up with the beater bars demonstrating their effectiveness of really getting the "crud" out from the base of the rug. That being said, I am impressed with the Lewyt.
Others vacuums that perform very well that I use regularly are: Kirby's, Electrolux's, (both upright and canister),and a Tri-Star and these brush rolls/power nozzles/agitators do not have that fine white/tan powder-like residue. Is it from the lack of a beater bar? Is it due to different brush roll design or air flow? I was told when I was very young by a vacuum store owner that when you see that residue, you have an effective vacuum cleaner.
Any thoughts on this?
