A strong all rounder for homes with kids, pets or allergies that want hot water mop washing and very little upkeep. TechRadar and Gizmodo both found it vacuums and mops well, but it still makes small mapping mistakes and has no mop only mode. At its $1,299.99 list price it is expensive, so wait for the coupon price.

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.

What reviewers found
eufy Omni E35
- TechRadar: Max power with two passes left carpet flawless and one low power pass cleared oats on carpet. Dried ketchup needed 100% water flow and a second pass. Measured 60 to 67 dB while cleaning. Subscores of 4.5/5 for design, performance and app. Source
- Gizmodo (4): Vacuumed and mopped a 750 sq ft apartment in about an hour with 64% battery left, faster than a Roborock Qrevo 2 Pro. Mopping was streak free, but it bumped walls and spun in reverse circles three times. Source
- T3: Rated mopping excellent on sticky stains and said the roller reaches skirting boards. Thick rugs were still a challenge, and a few water drops appeared around the dock. Tested on beta app software. Source
Eufy Omni S2
- Vacuum Wars (3.91/5): 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. Source
- TechRadar: 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. Source
- Android Authority: 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. Source
