I never leave reviews, but I always read them before buying, so I thought it time I contribute.

The cordless feature is just amazing. No more switching cords room to room or wrapping cords or tangles! My absolute favorite feature.

The second best feature is the sekllf cleaning brush. I had another Shark prior to this, which I loved, BUT the hair wrap on the brush, with every use, was terrible. Not having to worry about that any more is amazing!!

It's also very lightweight. I have two floors of carpeting to deal with and it is no problem moving between the two.

My only critiques would be , you lose a little cannister space with this version, and a tad stronger suction would be nice, but the max button is a good feature. 

Would definitely recommend. For a big house, you might want to go up a model. I live in a duplex, we do have a dog, and this model is perfect for our home.
