How does the roller mop differ from a spinning pad mop?

The S2 uses a single roller that scrubs with 15N of downward pressure and rinses itself at the station. Spinning-pad rivals press two discs against the floor but rely on the pad staying wet.

Will it wet my carpet?

No. The robot raises the roller mop and lifts its chassis for carpets up to 2 in thick, so it vacuums carpets without dragging a wet mop across them.

How often do I empty the dustbin?

The station holds a 3L dust bag, which Eufy rates for about 68 days of self-emptying before you swap it.

What do the water tanks hold?

A 2.5L clean water tank and a 1.8L dirty water tank feed and collect the mop wash water at the station.

Does it avoid cables and pet mess?

It uses 3D ToF navigation and recognizes more than 200 obstacle types, so it steers around common clutter rather than pushing through it.

Can it climb thresholds?

It crosses single-layer thresholds up to 1.4 in and double-layer thresholds up to 1.6 in.

Our take on the Eufy Robot Vacuum Mop Combo S2 Omni

The Eufy S2 Omni is a self-emptying robot vacuum and mop with a self-cleaning roller mop and a full wash-and-dry station. Its 30,000 Pa suction and AeroTurbo 2.0 airflow dig into carpets, and the chassis lifts for carpets up to 2 in thick while the roller mop rises to keep them dry. The rolling mop applies 15N of downward pressure and extends 0.59 in to reach edges, using electrolyzed water for sanitizing. It suits homes with a mix of carpet and hard floors that want hands-off mopping; rivals like the Roborock Qrevo and Dreame X40 also self-clean and self-empty, but few combine a roller mop with this much suction and a fragrance diffuser.
