We got ourselves a vacuum cleaner after a move and the acquisition of a cat. The assembly is done in less than 2 minutes and self-explanatory. The suction power is infinitely variable and there is a pilot light on the device in the event that the bag is full. The telescopic pole can be adjusted and the roll nozzle also has extendable brush. The small suction is very strong and absorbs everything whether dust, hair, sand or other contaminants. Really excited me was the fact that one has released in conjunction with the upholstery even blankets, pillows, bed surfaces and the scratching post of the cat in a few trains of fixed hanging cat hair. With many other devices that is always cumbersome and time-consuming. The bag holds a very long time even though we have to suck every other day. For me with a house dust allergy Micofilter is a blessing. Another product of Dirt Devil made me always to sneeze and the nose to run, that is not with the Siemens vacuum cleaner of the case. When sucking himself the unit is in large can draw well, but sometimes he is reluctant to something. What I noticed is that it automatically draws the line is carried out from time to time by itself when Afterward pulling. Whether it is stuck on a firm tug or I do not know. At the highest power level and from the middle, the device is still quite loud. But at the price we can only express a purchase recommendation, any time that sucker.
