My Dad had an Oreck-lasted 2 yrs. Then he got a Dyson I should say he got 3 Dyson lemons in less then 6 months. They did give him his money back and now he has a Shark. -he loves all the ''cool'' attachments. I have used it and if I was ever to have a house full of carpet again I'd get a Shark. They maneuver so much better then his Dyson's did. He has the original rug from when the house was built in 1930. I shampooed it last May -part of spring cleaning- and it does not look like it needs shampooed yet.
