The Verge’s favorite mopping robot vacuum is half off for Prime Day

Keeping your floors clean feels like a second job, but it doesn’t have to. Robot vacuums that can both suck up and mop them can make life easier, although many models out there need a fair amount of babysitting to ensure they’re doing good work. The Dreame X40 Ultra is different. It delivers a nearly hands-free cleaning experience and is currently available at a new low price of $699.99 ($800 off) at Amazon for Prime members during Prime Day.

The X40 Ultra is our favorite robot vacuum / mop hybrid. With 12,000Pa of suction power, it’s a good vacuum with dual oscillating mop pads that extend and swing out to reach edges, and can even clean under cabinets and consoles. Its dirt detection system spots messier spills — like milk or heavy dirt — and adjusts accordingly, going over messes multiple times for a thorough clean. It can even automatically remove and reattach its mop pads depending on whether it’s vacuuming or mopping, ensuring your carpets stay dry while you clean.

This model uses cameras combined with “3D-structured light” technology to map each room. It also offers good AI-assisted obstacle avoidance to steer around larger items like shoes, though it’s still wise to remove small objects like pencils, as it can get tripped up by them.

In addition to cleaning your floors, the X40 Ultra can clean itself. Its mop pads automatically wash and dry themselves at the dock. The robovac also empties its own dustbin, refills its water tank, and even cleans its washboard. All in all, it’s a relatively low-maintenance but powerful cleaning machine, and a great bot to consider at this price.
