Eufy X12 Pro vs Dreame X40 Ultra: Dreame wins on mopping, Eufy holds its own on vacuuming

On hard floors, both are close for vacuuming, but the X40 Ultra pulls ahead on mopping with its extendable edge pad and hot-water dock washing. If vacuuming is your priority, the X12 Pro is a solid choice; if mopping matters more, go with the Dreame.
