Sorry, but y’all have me (and probably others) thoroughly confused about this mop.
The first photo shows a non-spray mop and self-wringing bucket set.
The second and third photos show a spray mop, presumably the item on offer.
But then the copy makes it sound like a self-powered (Roomba-type) mopping appliance:
3 step cleaning system brings a deeper clean on thin carpet
Advanced powerful motor with Max mode lets A4 pick up more dirt effortlessly
Motorized low profile body with tangle free sensors avoids stuck or drop off
Up to 150mins working time delivered by high capacity fade-free battery
Automatically docks and recharges, convenient programmable schedule
