A situation

Are wet-and-dry robot mops worth it for small hard-floor homes?

A small hard-floor home needs a robot that vacuums and mops in one pass. The question is what these four give you at entry prices: the mop tank, the route, the dock and the run time.

Four robot vacuum-mops, each with its mop pad down, work across the one polished floor of a one-room flat: past the foot of the bed, under the table for two and along the kitchenette.

Small and hard-floored

What a wet-and-dry robot gives a small home

The four carry 150 to 400 mL of mop water. The M8 Pro is the only one found with a self-emptying station, and its maker's own store lists only accessories. The L70 Hybrid and G10+ charge on a plain base. The L70 Hybrid mops 30 to 70 minutes per fill.

Same on all four: one body that vacuums and mops from an onboard water tank, with a charging base or station.

By the front door of the flat, the black robot vacuum-mop sits docked in front of its tall black station, whose lid stands open over the dust bag it empties into.

Questions

What readers ask

How much water do these mop tanks hold?

The Bissell SpinWave lists a 400 mL clean tank, the M8 Pro 300 mL, the G10+ 247 mL in a hands-on review, and the L70 Hybrid 150 mL, which Eufy says lasts 30 to 70 minutes.

Do any of these empty themselves?

Only the M8 Pro has a station that does, per a hands-on review. The G10+ and L70 Hybrid charge on a plain base, and nothing was found for the SpinWave.

Can I buy all four new in the US today?

Not confirmed. Eufy’s US page shows the L70 Hybrid sold out. Proscenic’s own store lists only M8 Pro accessories. Bissell’s and 3i’s pages are live.
