Many write that the wire does not wind up, it turns out that there is a hook on the side on which you can hang it. At the first start, I had to use a syringe with water to blow out the water supply hole. As for the noise, it works no louder than a regular vacuum cleaner. Otherwise, I did not find any problems. Very pleased with this gift. Washes with a bang. This is now my main assistant in the house.
