eufy Omni S1 Pro Review: The Roller Mop That Changed What Robot Mopping Means

A self-washing roller mop and a 10-in-1 station deliver genuinely clean hard floors, but carpet suction and after-sales support divide owners.

The verdict

The eufy Omni S1 Pro is a flagship robot vacuum and mop built around a rolling Always Clean Mop that rinses itself continuously at 170 RPM while pressing 1 kg into the floor, so dirty water goes into a separate reservoir instead of back onto your tiles. Owners who bought it for hard floors are consistently impressed by how much dirt the mop lifts compared with spinning-pad robots, and the 10-in-1 UniClean station handles emptying, washing, refilling, heated drying and detergent dosing with almost no intervention. The trade-offs are real: 8,000 Pa is modest for deep carpet next to newer flagships, and a recurring thread in the reviews is frustration with warranty and support handling. Buy it for hands-off hard-floor cleaning, not as an all-surface carpet machine.

Best for
  • Hard floor and tile homes
  • Hands-free maintenance seekers
  • Pet households
  • Premium buyers

Pros

  • Self-washing roller mop with 1 kg of downward pressure lifts dirt spinning pads leave behind
  • 10-in-1 station: auto empty, wash, refill, heated drying, detergent dosing and waste-water collection
  • dToF LiDAR plus 3D MatrixEye obstacle avoidance navigates cluttered floors reliably
  • Square chassis and precision edge cleaning reach corners and baseboards
  • Mop auto-retracts 12 mm so carpets stay dry
  • Quiet in normal use at around 60 dB

Cons

  • 8,000 Pa suction is modest for deep carpet next to newer flagships
  • Recurring reports of dripping dirty water and mechanical faults
  • Warranty and support experiences are inconsistent in the reviews
  • 2.4 GHz Wi-Fi only, no 5 GHz band
  • No Matter, HomeKit or SmartThings support
  • Discontinued in the US, so spares and stock depend on remaining channels

Who is the eufy Omni S1 Pro for?

This is a machine for homes that are mostly hard floor and where mopping, not vacuuming, is the chore you want gone. The roller mop system pairs a 240 ml clean reservoir and a 220 ml dirty reservoir on the robot itself with a 3 L clean tank in the station, so it can keep refreshing the pad mid-run rather than smearing one wet cloth around the house. dToF LiDAR with TrueCourse mapping and 3D MatrixEye obstacle avoidance keep it moving around cables, shoes and pet bowls, and owners repeatedly mention that it navigates a crowded floor without bumping furniture. Multi-floor mapping and no-go zones make it workable in a larger house.

What buyers love

The mopping is the headline, and it is the thing owners bring up first: several describe running an existing robot mop daily and still being shocked at how dirty the S1 Pro's water came back on its first pass. The square chassis and edge-focused cleaning get repeated praise for reaching baseboards and corners that round robots miss, and more than one owner notes that edge performance improved as the map matured. The station's automation is the other favourite: emptying, mop washing, heated drying at 55 C and detergent dosing all happen without you, and the sealed dust bag keeps the emptying step clean. Several owners also single out fast, human responses from support when the app raised an error.

What to know before you buy

Carpet is the weak spot. At 8,000 Pa the suction is fine for hard floors and low pile, and the mop auto-retracts 12 mm before it crosses a rug, but owners with medium pile report having to follow up with an upright. There is a second, louder theme in the low-star reviews: mechanical and support problems, including dirty water dripping during cleaning, failed firmware updates and slow warranty resolution. It is also 2.4 GHz Wi-Fi only, so a dual-band router needs a dedicated 2.4 GHz SSID for setup. Note that eufy has discontinued the S1 series in the US, so treat it as an end-of-life flagship rather than a current model.

Is the eufy Omni S1 Pro worth it?

On hard floors it still does something most robots do not: it washes as it goes instead of dragging one dirty pad through the house, and the station means you touch it about once a month. If your home is tile, wood or laminate and you value mopping quality above raw suction numbers, it earns its premium price. If you have a lot of carpet, or you want the reassurance of a current, fully supported model, a newer flagship with higher suction is the safer buy.

Frequently asked questions

Does the eufy Omni S1 Pro empty and wash itself?

Yes. The UniClean station empties the robot into a sealed dust bag, washes the roller mop, refills the robot's clean water reservoir, collects the waste water, doses detergent and dries the mop with heated air at 55 C.

How well does it handle carpet?

It detects carpet and retracts the mop 12 mm to keep it dry, and 8,000 Pa is enough for hard floors and low pile. Owners with medium or deep pile carpet report needing a follow-up pass with a conventional vacuum.

Does it work with Alexa and Google Home?

Yes, it works with Amazon Alexa and Google Home. It is not Matter certified and does not support Apple Home or SmartThings.

Does it need 5 GHz Wi-Fi?

No, and it will not connect to one. The robot is 2.4 GHz only, so a dual-band router needs a 2.4 GHz band available during setup.

How long does it run on a charge?

Amazon lists 216 minutes of runtime, and the station recharges it in about 4 hours, resuming the job where it left off.
