This is my first review that I write. Anyone who is interested I can say for the device; BUY! Have already 2 Staupsauger destroyed with debris and dust from various electrical appliances. Our old vacuum cleaner attachment (Miele) for carpets also fits on it and the suction force is so great at max settings, I could not move the top of the site (Ha, Ha) So when one asserts the device does not meet its expectations, it has been broken or the one who is from the competition. Thank you
