Eufy Vacuums

Anker Innovations, the charging-accessory company founded in 2011, sells its smart-home products under the eufy name, one of five product families it now groups under the Anker banner. The robot vacuums carry the RoboVac and Omni names, and eufy's current store groups the Omni docks into three series: S at the top, E in the middle and C as the entry point.

The models listed here span that whole ladder plus some older machines. At the bottom, the RoboVac 11S Max ($280) is a no-app, no-map bump-and-turn robot; owners keep it for exactly that simplicity and its 2.85-inch height, and accept that coverage comes from running it daily. The now-discontinued L60 added camera-based obstacle avoidance without a dock. From the Omni C20 upward every model has a station that empties the bin and washes the mop, and the money buys mopping hardware: the now-discontinued X10 Pro Omni used twin spinning pads, while the Omni E28, the discontinued S1 Pro and the S2 switch to a self-rinsing roller mop. The E28 is the odd one out, with a detachable spot cleaner for upholstery stored in the dock.

Owners' reports split along floor type more than price. The S1 Pro's roller mop wins praise on hardwood and tile, but owners call it weak on carpet and say it strands itself on long-pile rugs. The S2 reverses that trade: owners credit it with much better carpet pickup and near-flawless obstacle avoidance, while its mopping uses so little water that dried stains come off less well than on the S1 Pro. E28 owners like the portable cleaner but name noise as their most common complaint, and both the E28 and the C20 wrap long hair around the brush.

Two things to check before buying. First, decide whether the house is mostly carpet or mostly hard floor, because the roller-mop models are not equally good at both. Second, check the warranty for the exact model and seller: eufy's own policy page lists 12 months for RoboVac models bought from its store and says terms can differ through third-party retailers.
