The Eufy Omni C20 robot vacuum and mop is currently available in certified like-new condition for $269.99; a brand-new unit is $379.99, reduced from its original $549.99 list price. According to price trackers, this refurbished deal marks the lowest price we’ve seen on the Omni C20 so far. As for its “like-new” designation, Eufy has inspected and restored the vacuum to full working condition, though minor cosmetic signs of previous use are possible. For anyone considering a robot vacuum that can both mop and empty itself, this discount significantly lowers the cost of entry (for more discounts and shopping advice, check out our Prime Day 2026 coverage).
The Omni C20 sits in the middle of Eufy’s lineup, combining vacuuming, mopping, self-emptying, and multi-floor mapping without venturing into flagship pricing territory. The dock handles much of the day-to-day maintenance, including charging the robot and wetting the mop pads before a cleaning cycle. It does a good job picking up crumbs, dust, and everyday debris, and it’s particularly effective at cleaning along baseboards and walls where dirt often collects. Beyond the cleaning itself, Eufy gives you a fair amount of control through its app, which lets you customize schedules, adjust suction power, manage room maps, and handle maintenance settings, while Alexa and Google Assistant support allows for hands-free control.
What do you think so far?
Unlike some higher-end robot mops, the Omni C20 doesn’t carry its own water reservoir. Instead, the dock moistens the mop pads before cleaning, which means the robot can’t continuously rewet them while moving through your home. As a result, mopping performance is better suited to light maintenance than tackling dried-on spills or stubborn stains. Obstacle avoidance is another weakness—power cords, small objects, and clutter can sometimes trip it up, so you’ll likely need to tidy up before sending it out. Still, for households with mostly hard flooring that want the convenience of automated vacuuming and mopping at a relatively affordable price, the Omni C20 offers a lot of functionality for the money.
