I bough this about 1 and half month ago, actually this is the second cord zero purchase in my life. 
I found this product had more features including mopping, combined smart two brushes into one, and a small nozzle for pushing down dust in the dust collection container. 
Unfortunately, the brush got broken( the brush stopped spinning)  in a month and I had to call customer service to replace, it was a hassle but everything went well. 
I have been using  dyson cordless products for multiple years. But they  died in a few years and had to buy again. But now I can not go back there since longer duration battery and two, nice touches like pushing down dust and one touch button for on and off, which does not hurt my index finger, also mopping functions. Love it.
