Yes it sucks more air than other battery powered vacuums but: in brief it is rather heavy and has very short battery life and no extension handle accessory. Even using the 18v so called long lasting $90 battery, it quits only after about 1,500 sq. ft of dusty floor space, about 15 minutes of use. Dewalt customer service said that it would pickup multiple bags of cement but it will NOT in my experience hardly do much dust off the floor. I spent $240 on the vacuum, charger, and best battery and feel this is too much for the results I got. The unit is light until the battery is put in then it is really heavy (I'm a 250lb man and think so). The body is wide bulky but should be narrow in format and longer since it bumps everything and bumps you in the side which is part of why it seems heavy.
