Robot vacuums show up in our gift guides almost every year, and it’s easy to understand why: they clean, they save time, and they’re cheaper than hiring a professional. But not all robovacs are created equal, and some save more time than others. The Dreame X40 Ultra is one of those, offering a more genuinely hands-free cleaning experience than what you typically get. And now through December 1st, it’s down to a new low of $499.99 ($700 off) at Amazon, Best Buy, and directly from Dreame.

If you’re looking for a great robot vacuum that also does a fantastic job of mopping, the last-gen X40 Ultra is one of the best we’ve tested. With 12,000Pa of suction power, it does a great job of sucking up dirt and debris. It even comes with AI-powered smart dirt detection, which uses onboard cameras to spot particularly dirty areas, then slows down and passes over them multiple times until they’re thoroughly cleaned.

Its dual oscillating mop pads also do a fantastic job on hardwood floors, even extending into edges and under cabinets. It can also automatically detach and reattach its mop pads when switching to vacuuming, so your carpets stay dry. In fact, it repeats this process multiple times throughout a cleaning cycle to ensure carpets are vacuumed and hard floors are mopped properly.

What’s more, the robovac doesn’t require much babysitting; it maps rooms effectively, and its AI-assisted obstacle avoidance navigates around larger items like shoes with ease. Plus, the X40 Ultra can empty its own dustbin, refill its water tank, and clean its washboard — and its mop pads can even wash and dry themselves.
