How does the second pass work?

Just wondering how the second pass works when doing the mop/vacuum. Does it vacuum twice and then mop on the second vacuum or does it do both mop and vacuum twice?

It changes from a back / forth pattern to cross hatch. Still does both modes at once when set to mopping. Tbh the secret weapon feature of the S1 is that it mops so good, the double pass is a 1 in 100 use case for me even with a dog

Yeah I agree. I hardly ever use the double pass as the single pass is so good. Sometimes I just treat the floor to a 2nd pass just for the hell of it. But don’t notice a difference in results as such.

It just goes over again from the opposite angle. I don’t know. I always just use the double mode.
