ok , so I want a powerful vacuum cleaner for my home that would be easy to maneuver , versatile , and lightweight . that be when I decide to conduct my own unconventional research into the best vacuum cleaner out there that would meet all of my expectation . I contact a array of janitorial and housecleaning service to hear they recommendation . this commercial Hoover backpack model be mention time and time again and I just could not resist buy it . I have use it a handful of time and let I tell you , it be a winner ! here 's why : 1 . it be so lightweight -lrb- 9.2 lb . -rrb- that even a frail person would have virtually no problem carry this on they back . 2 . it be very powerful ! 3 . the extra long , almost 50 ' cord allow I to plug it into a centralized electrical outlet on each floor and go from room to room without switch outlet . a real timesaver ! 4 . the floor attachment on this particular model have a very low profile and easily glide under furniture that be previously hard to reach . 5 . you can easily adjust the amount of suction when vacuum area rug so that they be not swallow up by the powerful motor . 6 . it use the hepa system . 7 . you have the option of use the cloth dust-catcher bag that come with it or disposable bag . for personal reason , I like have both of these option available to I . 8 . vacuum flight of stair be a breeze . no more awkward lifting of heavy vacuum cleaner from one step to another , which I have find to be potentially dangerous . I simply can not imagine myself ever go back to use heavy , bulky , roll canister or upright model . I be glad I listen to the commercial and residential cleaning service that I defer to for recommendation !
