Best robot mops for hard floors

Top pick: Narwal Flow 2 — the best mop-first machine here. Its roller mop washes itself as it goes, so it scrubs sticky kitchen and bathroom floors instead of just wiping them, and it's the highest-rated of the group.

Who the others suit:

• Roborock Qrevo Curv 2 Flow — the smartest all-rounder if you want one robot for both vacuuming and mopping, with a self-washing dock.
• eufy C28 — a self-cleaning roller mop for less; the sweet spot if you want the roller-mop idea without flagship money.
• iRobot Roomba Combo 10 Max — best if you already live in the iRobot app or want a dock that empties and refills itself for weeks.
• Shark Matrix Plus / Matrix 2-in-1 — budget-friendly everyday mopping for tile and laminate; fine on light mess, not on dried-on grime.
• Dreame X60 Max Ultra — the premium pick if you want the most features and don't mind paying for them.

Skip the sub-$250 no-name combos if mopping is the point — they wipe rather than scrub.
