performance , performance , performance . you will never be at a loss for suction with this vac . the floor and hose setting perform stellar . the strong agitator -lrb- very easy to adjust height -rrb- will clean the carpet in one pass . perform great 2 year later . pro - strong suction on floor and hose setting . even when bag start to get full . - Easy to switch between floor and hose . - Great HEPA filter . last a year . the generic one I buy make the air smell really fresh . - you can not beat the price ! con - hose could be longer . not good for clean ceiling cobweb . get a swiffer . - heavier than most vac . not a good gift for grandma . - louder than most vac . Mack 's ear seal . - powerpaw attachment do not work well . who care ? - Weird Thing : Vac start make high pitched squeal one day . a small hole on the back , where the cord be , be let air through . not sure if I knock a cover off ? one piece of Duct Tape solve that problem . Works Great !!!
