this be a well design , powerful , medium-to-lightweight , versatile backpack vacuum , as other reviewer have say . I have be use it for a little over a year and would purchase one again . some important caveat : First , the Hoover dust brush that come with my vacuum be poorly design and poor quality . the plastic bristle immediately collapse inward block most of the suction . I buy a Kirby real-bristle dust brush -lrb- $ 10 -rrb- , which fit right on the hose and work very well . also , the combination floor tool that come with my vacuum be great for carpet , but I want a real floor brush to use on hardwood floor . when I contact Hoover , I be tell that the optional floor brush picture in my manual be no longer available . I buy a Kirby floor brush -lrb- $ 25 -rrb- that fit snugly and work perfectly , protect my wood floor . finally , the Hoover or Royal BP paper bag be outrageously flimsy & overpriced -lrb- 7 for about $ 10 -rrb- . despite frequent bag change involve normal interior dust and dirt , nearly every bag I use split or tear , usually at the glue seam . this result in a filthy hypercone filter and a filthy , time-consuming cleanup job every time I change bag . over time , the dirt enter the inner chamber may also threaten the longevity of the vacuum motor . shame on Hoover ; do not they test they bag ? anyway , to address this issue , you can double up on the paper bag , or use both a paper bag and the include cloth dust bag , with the paper bag over & inside of the cloth bag . I have try both option . so far , both option have prevent the inside paper bag from splitting w\/o seriously soil the second paper bag or the cloth bag -- or allow dirt to enter the interior chamber . judge from the sound of the vacuum , it do not seem to be strain or work harder with two bag , as long as I regularly replace the inside paper bag when it be dirty . with the paper bag inside the cloth bag , the cloth bag stay pretty clean and just need a shake or two when I change bag . with two paper bag , the outside bag remain clean enough that I use it again when I change bag .
