Roborock S8 Pro Ultra Robot Vacuum and Mop
Verdict
Roborock S8 Pro Ultra remains one of the best pure cleaners here, with excellent hard-floor pickup and the strongest obstacle avoidance in this group, but its dock design quirk and very high price hold it back. It is a good fit if you want flagship cleaning and navigation and can accept paying a premium over better-value Q-series options.
