after careful review of all the option for a backpack vacuum , I choose this one . first , the review be great . I think the spec seem right for I , and the Hoover brand be a good one . I have replace a thirty year old , but still work , hold in you hand variety . I be older now and have difficulty with my hand . I place the order right in the midst of the holiday rush . I receive confirmation of the order and then the notice of shipping . it get here in three day . the day it arrive , I have just be home from have knee scope surgery for a few hour . I be sit packed in ice , but I have to try it out . I read the direction , I sit it on the counter and back into the strap . after secure the waist strap , I plug it in at a socket that I think would not have to be move . I be right . I have 1750 square foot on one level . with the 50 foot cord , I be able to get around my entire house . the suction be very powerful . I have puff of dog hair around most of the time and they come rush into the hose from a foot away . the wand be fabulous on the baseboard and up in the corner on the ceiling . the rug attachment work amazingly well on my area rug and small throw rug . best of all be the great job on the hard wood floor with the very same attachment . I have recommend this product already to a friend and she feel the same way about it . hip , hip , way to go !  Hoover Commercial Shoulder Backpack Vacuum Cleaner
