eufy Omni S2 Robot Vacuum review

For homes with lots of hard floor where mopping quality matters most; reviewers rate its roller mop and water sanitation among the best available. The trade-off is navigation, which reviewers consistently describe as weaker than Roborock's.

A premium robot vacuum with a self-cleaning HydroJet 2.0 roller mop that presses down with 15N, rated at 30,000 Pa suction, and a station that empties the bin and sterilizes the mop water.

How we pick and rate products

1

Shortlist what's worth buying

We start from models that are actually sold and supported in the US, and drop anything with a pattern of reliability, app or support problems.

2

Research, not spec-sheet copying

We weigh manufacturer specs against independent lab measurements, professional reviews and long-term owner reports, and write down where they disagree.

3

Score with the trade-offs visible

Each product gets a 10-point score against the criteria that matter for its category, with the pros and cons that produced it.

Commissions don't pick winners

We earn from some links, but which store pays more never decides what we recommend. If the best option is somewhere we don't earn, we still say so.
