Flagship robovac war: Roborock Saros Z70 vs DEEBOT X11 vs Dreame Aqua10 — pick one to run your floors

All three cost more than my first car (fine, my first car was terrible). Z70 has the OmniGrip arm that literally picks up socks. X11 has the bagless OmniCyclone dock and monster pet-hair suction. Aqua10 has the self-washing roller mop that never smells.

You get exactly one, it runs daily for two years. Which one are you trusting with your floors — and does anyone actually regret going flagship instead of buying two mid-rangers?
