I had a Dirt Dervil, processing was good and sufficiently stable, the suction force was very good and the service also good. A shortage there, the handpiece was put on the pipe without locking area and was therefore constantly loose. However, an advantage had this model, an electronic, manually adjustable suction power. This model here is a lock on the handpiece to the tube has also keeps its promises this. But there is no suction. The slider on the handpiece brings as nothing. On carpets the part sucks so hard that you can not suck with normal effort. A constant off the ground thus can not be avoided. Carpeting can not suck you so. I would like 10 more invested in this model with a digital suction power. So I can not recommend this model for carpets. I'll make my right of return and buy a corresponding model with suction. That's a bad design, or notice missing, not suitable for carpeting.
