eufy Robot Vacuum Omni C20, Robot Vacuum and Mop Combo
Verdict
The Eufy Omni C20 is a standout budget robot vacuum-mop with excellent mopping, strong everyday pickup, and a very capable all-in-one dock at a low price. You give up long runtimes, strong crevice performance, and advanced obstacle avoidance, but if you can live with average navigation and more frequent returns to the base, it is one of the best-value combo robots available.
