The Eufy X12 Pro holds its own on hard floors against Dreame's X40 Ultra

On hard floors, the Eufy X12 Pro and Dreame X40 Ultra are surprisingly close for vacuuming. The X40 Ultra pulls ahead on mopping thanks to its extendable edge pad and hot-water dock washing — features the Eufy doesn’t match. For homes with mostly hard floors where vacuuming is the priority, the X12 Pro is a solid choice; if mopping matters more, the Dreame is the one.
