eufy Omni E28 Robot Vacuum and Mop Combo

Verdict

A highly capable premium robot that vacuums and mops extremely well and adds a genuinely useful built-in spot cleaner, with standout obstacle avoidance and a powerful multi-function dock, though long hair clumping, a tiny onboard dust bin, loud dock cycles, and some streaking on hard floors mean it is best for homes that can live with those tradeoffs.
