I come here for your collective wisdom
Can't work out which one to get
I got polished hardwood floor and tile no carpet, large house two floors 5 beddies and two living areas
which one you reckon do a better job?
Price wise I think they are similar price unless someone can point out some bargain
Sounds like with your type of floors you'd be interested in the mopping function too. The S7 has a vibration feature that "scrubs" the floor rather than dragging a wet cloth around. I'm not sure about the Ecovacs.
I'm waiting on the S7 Maxv Ultra to drop in price with the S8 release. Unless the S8 is not marginally more expensive and there are some improvements from the S8.
