With the year coming to a close, now’s a good time to set yourself up for a cleaner, more organized start in 2026. The Dreame X40 Ultra — one of our favorite robot vacuum deals from Black Friday — can handle most of the heavy lifting for you, and it’s once again on sale. You can currently buy it for $503 ($697 off) at Amazon at checkout, which is just $4 more than its record low price set during Black Friday.
Before the Dreame X50 Ultra took its place, the X40 Ultra was our favorite robovac / mop hybrid for hard floors and carpets. Like the X50 Ultra, it delivers excellent mopping performance, thanks to dual oscillating mop pads that can extend into edges and reach under consoles and cabinets. It can also automatically detach and reattach its mop pads when switching between mopping and vacuuming.
While the X50 Ultra is nearly twice as powerful, the X40 Ultra’s 12,000Pa of suction is still more than capable of handling everyday dirt and debris. It also features AI-powered dirt detection, allowing the robot to slow down and make additional passes over especially dirty areas. What’s more, the X40 Ultra can empty its own dustbin, refill its water tank, and clean its washboard, with mop pads that wash and dry themselves for minimal upkeep.
What you don’t get are some of the newer X50 Ultra upgrades, including the motorized swing arm that lets it clear higher thresholds and the improved dual rubber roller brush system, which does a better job picking up fine debris. That said, the X40 Ultra still performed very well in our testing, making it a great investment — especially considering it now costs about half as much as its successor.
