My expectation was that it will continue to work for at least six months to a year. It's possible that it will come in handy. But, the power that made me so happy during the first cleaning was sufficient for four cleanings and lasted for a whole month. Now it does not stick to the floor, and it pulls weakly even though the container has been thoroughly cleaned and the valve has been closed. Extremely upset We'll need to get in touch with the guarantee, spend some time figuring out what's going on and how, and in all likelihood, get no response.
