The device has 2 major flaws or namely design error:
1) The pipe or the diameter of the opening of the stainless steel pot to the hose is big with nearly 5 cm, but is the "knee" inward at a 90 ° angle narrow in the pot inside. The knee is thus equal to or smaller than the hose diameter, and has a small opening to the inside. (I have unfortunately not photographed, but this will supply later, once I even see an exhibit at the hardware store!) This means that there gather all small parts, and can not be transported. For other manufacturers (such as Famulus [however the 3x cost, so you have to be fair], unfortunately, the old has gone kaput) this has been handled better by having taken inside a larger diameter than the knee. There, the tube, for example, 4.5 cm thick, but the knee internally has a diameter of 10cm. Thus there is no danger that parts get caught in the knee.
2) The bag usually clogged after a few seconds the suction, as by the cover with motor with plastic wall located directly behind the collection bag. The bag can therefore not inflate or fill, since the wall of the motor or the cover forms a barrier almost directly to the socket of the collection bag. One can imagine this as as if you would hold your hand just in front of the vacuum cleaner nozzle. It's suction power is lost, and an unnecessary amount of energy is required that the suckers conveys the material. I wonder who has since expended on the design? It's bad when you see this and basically thinks: That can not be true, but something you have to see in the design or "feel".
Wet cleaning I then no longer tried. The suction was generally average, the constant clogging ended up being the KO criterion. Thanks to the goodwill of the construction market has taken him back, and I am happy. For me it is clear that I will never again make the mistake and am going to buy a vacuum cleaner from Kärcher. The high pressure washer may be good, but vacuum cleaners build other companies better. And I would only buy a vacuum cleaner longer, if I can try it out on the spot. The Karcher looks sleek, but is basically a bad design. But can not know in advance if you have not paid attention to the knee so.
The difference between MV and MV 5 P 5 Premium Premium is the way of the outlet port. Those who need it. But would anyway advise to other devices.
Today I release the "larger" watch brother MV6, which also has internally only on the small "knee". Say, it helps the whole Grobschmutzset with 6cm diameter nothing if there is the same small bottleneck in the boiler. Incomprehensible, how to build something.
