In turbo mode, indeed, it does not work for a long time and the charge runs out quickly. But with the included nozzles, even in normal mode, it copes with a bang with wool and fine dirt on carpets. For an Apartment of 60 squares, the charge is enough for two cleanings. I recommend it for purchase, I was very pleased, and it helps out with a bang when there are children in the house, and even animals.
