My dog notices floor residue way before I do and now I can’t ignore it

I swear my dog has stronger opinions about my floors than I do. He’ll happily flop in one room and then weirdly avoid another right after I mop, which made me start paying attention to what’s actually left behind instead of just whether the floor looks nice for ten minutes.

Real experience is, regular water and electrolyzed water did not leave the same feel behind, and I only started noticing because he did first. Maybe I’m overreading dog behavior, totally possible, but now I’m kind of stuck on that whole what’s left behind after mopping question, because pets are literally closer to the floor than we are.
