this vacuum be very powerful and for be as heavy as it be , it be easy to use and seem to self-propel . I have all hard-wood floor with area rug and the CPU be so strong that it sometimes suck up the rug 's edge . overall , my biggest problem be the lack of a extension hose . the booklet that come with the vacuum state that it should have come with the extra hose but the vendor claim that the short nozzle hose be all I get . it be too short to use with the tool . if true , then the booklet be not correct . so far , the vendor , MoreQualityLessMoney have not be helpful . bottom line , make sure you get the hose .
