A simple, very slim robot for small homes that just want daily crumbs and dust handled on a budget. Reviewers found its suction good for the price, but it has no app, no mapping and no auto empty, and it bounces around at random. Spend about $80 more on the Roborock Q7 M5+ if you want mapping and a dock.

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 11S Max
- TechHive: The jump to 2,000 Pa lifted more crumbs and pet hair, especially on carpet, and it crossed carpet to hardwood smoothly. It navigates by driving straight and turning on contact, so cables should be tidied. Source
- The Ambient: Removed most of the dirt in its runs and was very quiet in standard mode, but with no app or mapping it bounced around at random, choked on cables and got wedged between chairs. Source
- Mighty Gadget (87%): Left a full bin after each room and rarely caught on cables; the reviewer did not run formal suction tests. 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
