That's my next video later on today, That's what I really wanted. So as far as I can tell, you ask it to "clean a specific room" it will do a vac and mop together simultaneously...which I don't want. I just want to vacuum sometimes. You can't ask it to Vacuum or mop a room specifically, if u you want it to just vacuum or just mop it has to be has to be a full house clean. So you say "vacuum only" it will vacuum only....but the whole house. Also you can say "clean here" it will find you but again, it mops and vacuums together which is annoying if it's not a wet spill
So I had the S7 Max V Ultra, it suction was definitely better and the mopping was the same I feel. I didn't try the S series. I do feel with the S7 Max V Ultra, the roller brush couldn't rise up so I feel it broke up dirt that would then be wiped by the mop following right behind. I had an S8 Max V also, the detergent despenser was broken out of the box. So I only used it for a few days, more moving parts are always concerns for the future reliability factors. but I'd say the Q Revo Master is the best value for money entirely.
