I have been using it for almost 3 years, almost every day at the store where I work. At first, it was quite powerful, but as time goes by, it discharges excessively quickly (in less than half an hour on the medium setting) and within 3-5 minutes on the high setting. It is unacceptable because unfortunately, if you don't put it on high, it doesn't work well and often needs to be "lifted" a little to work properly. Also, I have it in a store so this doesn't affect me, but for anyone who wants it for home use, I would like to mention that due to the construction of the vacuum cleaner, which is quite wide, it will not fit under sofas and beds. The only positive thing about it is that it has a fairly large dustbin and rarely needs to be emptied, and overall it is portable, which is incredibly convenient. Otherwise, I really believe that there are much better options available for the same price.
