eufy Robot Vacuum Omni C20, Robot Vacuum and Mop
3.9
(11)
Bottom Line
Choose if you want a slim, self-washing mop dock robot that mops impressively for the price; Skip if you need strong obstacle avoidance or long single-charge runs. Tradeoffs: small onboard bin/battery efficiency, and modest mop-lift on thicker rugs.
Best for
Smaller-to-mid homes with mixed hard floors and rugs that want hands-off vacuuming plus genuinely useful mopping in a compact, under-furniture-friendly robot.
Not for
Homes with lots of floor clutter, cords, or frequent pet accidents, and large floorplans that need long uninterrupted cleaning without extra dock trips or recharge breaks.
Verdict
The eufy Omni C20 delivers a lot of the full dock experience at a lower cost: auto-emptying into a bag, mop-pad washing and air drying, and a low-profile robot that gets under furniture easily. Across reviews, its spinning-pad mopping is the standout, handling everyday grime and even dried messes better than typical budget combos, while debris pickup on hard floors and most carpets is solid. The tradeoff is intelligence: obstacle avoidance is basic, so cords, toys, and pet accidents can become problems unless you pre-tidy. Expect more dock trips and breaks too—its onboard bin is small and battery/coverage is below average in heavier modes.

-
AI, Smart & App / Automation 4.0 ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 4.0The app experience is widely seen as polished and easy to use, with mapping, schedules, room controls, and dock options; advanced niche controls are lighter than top-tier apps.

-
Noise level 4.0 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 4.0Noise is generally acceptable for a robot combo, but boost mode and dock auto-empty can be loud enough to notice in nearby rooms.
-

-
Suction & Airflow 3.9 ★ ★ ★ ★ ★ ★ ★ ★ ★ 6 reviews 3.9Suction is generally described as strong for its class (rated 7,000Pa), with good real-world pickup, but multiple tests note below-average airflow that can reduce performance in deep crevices.

-
Edge & Baseboard Cleaning (Hard Floors) 3.2 ★ ★ ★ ★ ★ ★ ★ ★ 1 review 3.2Edge/baseboard cleaning is adequate but not perfect; spinning pads and brush layout can leave a narrow strip that may need occasional spot attention.
-
Mop lifting system 3.1 ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 3.1Mop lifting is helpful for mixed floors, but lift height is limited; thicker rugs can still get contacted, so no-mop zones may be needed.
-
Crevice / Groove Pickup (Hard Floors) 3.1 ★ ★ ★ ★ ★ ★ ★ ★ 1 review 3.1Crevice/groove pickup is a weaker spot, likely tied to lower airflow; it may leave some grit in cracks compared with stronger airflow robots.
-
Obstacle Avoidance (Robot) 2.7 ★ ★ ★ ★ ★ ★ ★ ★ 7 reviews 2.7Obstacle avoidance is consistently the biggest weakness; it lacks more advanced vision and may hit chair legs, snag cords, or run over small clutter unless the floor is picked up first.
FAQ
Does the Omni C20 wash and dry its mop pads automatically?
Yes. The dock washes the spinning mop pads, pulls the dirty water into a separate tank, and air-dries the pads after runs, reducing daily hands-on cleanup.
Will it avoid cords, toys, and pet waste?
Not reliably. Reviews consistently describe obstacle avoidance as basic, so you will get better results if you pick up clutter and use no-go/no-mop zones in problem areas.
Is it good on carpets as well as hard floors?
It is solid for routine carpet pickup, especially low- and medium-pile, and it can lift/stop the mops when carpet is detected. Deep cleaning thick carpet still favors higher-end robots or an upright.
How often do you need to refill or empty the water tanks?
Tank intervals vary by home size and how often you mop, but multiple reviewers note the tanks are on the smaller side, so expect more frequent refills/empties than larger-dock competitors.
How is battery life?
Battery efficiency is commonly cited as below average in higher-power or frequent-pad-wash cleaning, so larger spaces may require recharge breaks and longer total job time.
