Chose between V9 and V10. I ordered V10 - at a promotional price, but it was not in stock ((((. As a result, I reordered V9 It doesn't hurt to hold the button. Charging for a one-room apartment without carpets, with pets, abound (in the second mode). Enough power, collects all the garbage, does not scatter. The V10 has a flexible hose and more power, now I understand that it would probably not be very convenient to use a flexible hose, since one hand holds the motor and presses the button, the other has a flexible hose) maybe I'm wrong. I saved money and have no regrets. I recommend
