From all the research I did, Wessel Werks came out on top for the center vacuum nozzle. And this one lives up to expectations. Powerful, height-adjustable, manoeuvrable. I've been using this thing for about 50 hours and this is how carpet vacuuming should be. The attachments are better than the other two sets I have. For example, the "turbo brush" has a well thought-out cleaning flap that makes this work easier. The crevice tool is longer and narrower than the others I have. Some outstanding features of the Wessel factory drive head are: 5-way height adjustment. LED light. Excellent swivel mount design that allows you to get under furniture or simply turn direction with a slight twist of your hand. The powerhead feels like a no-brainer when you choose the right carpet height. The only thing I would change is the hard plastic head with hard edges - I used it to cut the baseboard and furniture legs. Every good vacuum I've owned had a rubber bumper to protect the furniture; Wessel Werks could be improved if they did the same. Also, the extension (the metal "tube" from the handle to the power head) also has hard-edged plastic parts that also scratch furniture. They should also be rubberized (or at least soften the curves around the edges). I'm learning not to knock on furniture. Otherwise I am completely satisfied with the machine, hose and accessories. The delivery was quick and it was well packaged.
