Eufy Omni S2
Eufy's roller mop flagship with perfect obstacle avoidance scores
Researched by Riley Hart · updated Oct 16, 2026
It was $320 cheaper ($1,280) during Prime Big Deal Days 2026. Black Friday is Nov 27, 2026, 31 days away, and big sales usually return then. Get a price drop alert or see every tracked deal.
A good fit for busy homes with carpet, pets and clutter on the floor, since it was the only robot here to avoid all 24 obstacles in Vacuum Wars testing and it never tangled hair. Mopping is fine for daily grime but several reviewers found it weak on tough dried stains. Skip it if stain removal matters most or if you mind paying for Eufy's own detergent and fragrance refills.
Best for: cluttered homes with carpet and pets. Skip if: you need strong stain removal.

What independent reviewers found
- 87% carpet sand removal (S1 managed 61%), 88.5% flattened pet hair, 0% hair wrap and a perfect 24 of 24 obstacles; dried stain mopping and navigation speed were below average.
- Vacuum Wars · 3.91/5
- Much better vacuuming than the Omni S1 with strong mopping and reliable navigation; about 55 dB in Quiet mode and 70 dB in Cyclone mode; one unit developed a connection fault and was replaced. Rated 5/5 design, 4.5/5 performance and 3.5/5 value, with no single overall score.
- TechRadar
- Called it one of the best robot vacuums the reviewer has tested, with zero collisions and no hair tangles, but noticeably louder than other recent flagships.
- Android Authority
- T3 Recommends award; removed a stubborn stain in one pass and needed dock emptying only about every 68 days, though fluffy rugs remained a weak spot.

Do I have to use the fragrance feature?
No, it is optional. Reviewers note the cartridges are an extra ongoing cost.
Is it better than the Omni S1 Pro?
For vacuuming and carpets, yes, by a wide margin in Vacuum Wars testing. For stubborn dried stains, Vacuum Wars and National World found the older S1 did better.
