Is the small size a real tradeoff, or just a marketing point?

It's a genuine tradeoff both ways. At 3.35 inches tall it reaches under furniture taller all-in-one robots can't, but that compactness comes with a smaller 250mL dustbin and below-average battery efficiency (about 525 sq ft per charge vs. a 1,015 sq ft average), so it needs more frequent dock trips in mid-size and larger homes.

How good is the mopping compared to other combo robots?

Genuinely strong - independent testing scored it well above the category average on combined mopping metrics, with particularly good dried-stain removal and less residual water left on floors than most competitors. This is one of the model's clearest strengths.

Does it handle pet hair well?

It depends on the hair length. Short pet hair pickup tested excellent at 96%, well above average. Long hair (7+ inches) is a different story - it tangles around the brushroll at 54% versus a 38% average, so long-haired dogs and cats will need more manual brush maintenance.

Does it avoid obstacles like cords and toys?

No - there's no camera or structured-light obstacle avoidance system, so floors need to be cleared of cables, socks, and toys before each cleaning run.

Does it clean edges and corners well?

Not especially - crevice and edge pickup tested notably below average in independent testing, which lines up with airflow measurements coming in about 25% below the category norm. Expect some dirt left along baseboards that a stronger-airflow competitor would pick up.

Who should buy this over a bigger Omni-class robot?

Households with mostly hard floors, short-haired or no pets, and a specific need for its slim under-furniture clearance are the best fit. If you have long-haired pets or want top-tier edge cleaning and obstacle avoidance, a larger flagship all-in-one competitor will serve you better.

eufy Robot Vacuum Omni C20

Name: eufy Robot Vacuum Omni C20
Brand: Eufy
Price: 380 USD
Availability: InStock

eufy quietly replaced the RoboVac G-series with this C-series, and the Omni C20 is the one that undercuts everything else in eufy's self-emptying lineup. It uses real LiDAR (eufy calls it iPath) instead of the gyroscope nav on eufy's cheapest bots, so mapping is fast and rooms come out named correctly instead of guessed at. The all-in-one station handles emptying, mop washing, drying, and refilling water, which is rare at this price - most competitors make you step up $150-200 for that combo. 7,000 Pa is solidly mid-pack, fine for bare floors and light carpet but not a pet-hair specialist number. eufy doesn't publish noise, runtime, or weight for this model, which is typical of their spec sheets and worth knowing going in. The Pro-Detangle Comb is eufy's answer to hair wrap, and multi-floor mapping means it'll actually remember your upstairs and downstairs separately. At its street price this is one of the cheaper ways into a full self-emptying vac-and-mop combo, full stop.

Highlights

All-in-one station at a budget priceReal LiDAR, not gyroscopeMulti-floor mapping

Pros

✓All-in-one station (empty, wash mop, refill water) is unusual at this price point
✓Real LiDAR navigation instead of the cheaper gyroscope nav eufy uses on budget models
✓Multi-floor mapping keeps separate maps per level
✓Carpet detection auto-boosts suction and lifts the mop
✓Noticeably cheaper than eufy's Omni S-series or X10 Pro Omni

Cons

✗7,000 Pa is mid-pack suction, not a strong pet-hair pick
✗eufy doesn't publish noise level, runtime, weight, or dimensions for this model
✗No hot water mop washing (cold water rinse only)
✗eufy's app and firmware updates lag behind Roborock/Dreame in polish

Owner Insights

The eufy Omni C20's whole pitch is fitting a genuine all-in-one system - self-emptying, mop-washing, mop-drying - into a body slim enough to slide under furniture that taller Omni-style docks and robots simply can't reach. At 3.35 inches tall, it's noticeably more compact than most flagship all-in-one competitors, and owners who specifically needed that clearance treat it as the main reason to buy this over a bulkier rival.

The practical upside shows up most clearly in mopping, where independent testing scored it well above average on combined metrics, including strong dried-stain removal and less water left behind than competitors - genuinely good performance for a mid-tier combo unit. Short pet hair pickup is similarly strong at 96% in testing. The tradeoffs are real, though: the small 250mL dustbin and below-average battery efficiency mean more frequent dock trips than a typical Omni-class robot, long pet hair tangles significantly more than average around the brushroll, and there's no obstacle avoidance, so pre-clearing the floor is part of the routine. Edge and crevice cleaning also tested below average, likely tied to airflow that runs about a quarter below the category norm.

This is the right choice for a household with mostly hard floors, short-haired pets or none at all, and a genuine need for the compact form factor - under-furniture clearance that competing all-in-one docks can't match. Long-haired-pet households or anyone prioritizing thorough edge cleaning and obstacle avoidance should look at a larger flagship Omni-class competitor instead, where the C20 gives up some capability specifically in exchange for its slim profile.

Pros

+Unusually compact for an all-in-one system - at 3.35 inches tall it reaches under desks, low bed frames, and cabinet toe-kicks that taller Omni-style robots can't get near
+Mopping is a genuine standout - independent testing scored it well above average on combined mopping metrics (227 vs. a 171 average), including strong dried-stain removal, and it leaves noticeably less water residue on floors than competitors
+The all-in-one dock automatically empties debris, washes the mop pads, and air-dries them with minimal owner intervention, which owners consistently cite as the reason to pick this over a cheaper vacuum-only bot
+Short pet hair pickup is excellent - testing measured 96% removal of flattened pet hair, well above the 81% category average
+App covers the essentials cleanly: multi-floor mapping, no-go zones, room-by-room scheduling, and Alexa integration
+Strong value proposition for a compact combo unit that fits spaces bigger flagship Omni docks physically can't

Cons

−The dustbin is small at 250mL, and combined with below-average battery efficiency (covering only about 525 sq ft per charge versus a 1,015 sq ft average), it means frequent trips back to the dock in mid-size or larger homes
−Long pet hair is a real weak spot despite the strong short-hair number - 7-inch strands tangled around the brushroll at 54% versus a 38% average, so long-haired dogs and cats undercut the otherwise excellent pet-hair story
−No obstacle avoidance - there are no cameras or structured-light sensors, so cables and toys need to be cleared before every run
−Crevice and edge pickup tested notably below average, meaning dirt along baseboards and room edges gets left behind more than with competitors
−Airflow tests roughly 25% below the category average despite adequate raw suction, which likely contributes to the edge-cleaning and long-hair shortfalls
−Overall lab score placed it mid-pack (46th) among tested robot vacuums, so it's a specialist in size and mopping rather than an all-around top performer
