I just bought mine today X7 model. Just finished vacuuming my house. Wow, what a difference it made. My home has different floor surfaces, from tile, to wood floor, to lot's of area rugs. My rugs look brand new, the X7 model really adjusts to all the different rugs and floor types of my home. The area rugs look brand new.

All it needs is a brush roll on/off feature.. At least in upright mode, it's extremely annoying when you vacuum nocks and crannies while brush roll eats your carpet..

thanks so much for this great video!

Good upload. Well done.
