I am very impressed with the power and how quiet this vacuum is.  I wasn't expecting much suction power considering how quite the motor is on low but it performs very well.  I went over an area that I used my Kirby on just before the LG and it still picked up more that the Kirby left behind.  I believe this is because the power head sits against the floor instead of being slightly higher than a traditional vacuum.  This vacuum is worth the money.  I have not used the mop/scrubbing head yet but, I don't expect this will be any less impressive.
