Thank you for the video. Looks like a great solution from Dyson; however, also could been build as a attachment wand for any current cordless vacuum with updated programing like the Submarine head which would cut down the storage space and decrease the need of environmental waste on extra battery pack and charger. I think the Anti-Tangling comb maybe possibly be build into the molding of the debris collecting tray itself to effective remove hair from the bristle hair brush roller without the possibility of the hair to enter into the dirty water intake tank to cause suction clog. Thanks again for the video.
