Wish I had retired my heavy Dyson and bought this sooner. I bought the corded one, which occasionally gets in the way of my vacuuming trajectory but it's powerful and consistent suction. Connections are easy to reconfigure. My right arm is in a cast and I have been able to vacuum my house w/my left arm because of this versatile Shark unit. Only drawback is that with 3 dogs, the small dirt receptacle must be emptied 2-3 times to finish vacuuming my 1960 sq ft home. But its technology excludes rollers that would clog with long hair. so on the whole, I am pleased with the value and functionality.
