A:Answer AW stands for Air Watts, which is calculated differently from watts. Watts calculate the input electric current, and Air Watts is directly correlated to the actual movement of air generated by the suction power. A standup Hoover, for example, generated around ~100AW on a 1600W model. So I imagine your 2000W Bosch generated ~150AW or somewhere around there. 65AW isn't bad for a portable, and frankly I have no problems using it on carpet.
