Sadias are more of a professional vacuum -- they're used by a lot of floor refinishers and installers -- so you really don't hear about them in the consumer market much. It picks up everything
and it really gets close to the walls and into corners easily.
It weighs about 5 pounds but it's big. We have some smallish rooms and when using the long handle it can get tricky turning around, I bump into a lot of stuff. It took me a while to master it but it was worth it.
The price is really good too when you compare it to other vacuums.
