I am a Shark lover! I am also very frustrated! I own 2 upright Lift Away’s and two hand helds. My problem is that the hand helds I own came with a revolving attachment which made them EXCELLENT! Then both attachments died! One was for the house and the other for our cars. You couldn’t beat them! Nw I cannot find nothing to replace them, pure suction doesn’t work and the replacement models are worthless I haven’t been able to find replacement parts, can you help?
