The WashG1 is Dyson's first machine built purely for wet cleaning, and it works nothing like a vacuum. There is no suction motor at all. Two counter-rotating microfibre rollers do the work, fed by 26 hydration points that lay clean water down and then lift the dirty water straight back off the floor.
Wet and dry debris separate at the source. Crumbs and hair drop into a removable tray behind a 500-micron mesh while extracted water goes to its own tank, so nothing turns to sludge inside the machine.
One tank covers around 3,100 square feet, and a self-clean cycle rinses the rollers afterwards.
