I have have this vacuum for about a year now , replace my bag 12 amp Dirt Devil when it die , slay by my long hair . I shed quite a bit , and the poor Dirt Devil 's motor and brush be no match for my hair 's ability to clog the brush and muck up the work . enter the Bissell Cleanview helix . it do a great job , and between two filter and the main debris canister , get a ton of stuff . I love the on-board attachment -- they all work well -- and the ability to adjust the main vacuum brush to the floor surface -lrb- it have about five setting depend on how high you carpet nap be , include a bare floor setting , perfect for my 6 square foot of kitchen tile . clean the top filter be super-simple and can be do in less than a minute , but the bottom one take a bit more work -- all of five minute . oh , life be hard . Minus one star for the allergy-triggering that happen when I empty & clean the vac filter .
