A:AnswerThere are five levels of height adjustments on the machine. The suction is very powerful and raising the level reduces the suction so the machine moves a bit easier.
A:AnswerDid you try changing it to 3/4? Vacuum needs to be adjusted on some carpets/rugs. You won't notice much difference in suction, but it will be a lot easier to handle. Beware too, as I almost destroyed one of the smaller rugs by using setting 2 and tearing corner apart. Never again! Once you know which setting to use for what it will be a breeze=)
