If you like the idea of investing as little effort as possible into mopping your hardwood floors, you might want to check out the current deal on the Narwal Freo X Ultra. Right now, our favorite robot vacuum for mopping is down to its second-best price of $999.99 ($400 off) at Amazon, which is just $50 shy of the all-time low we saw during Prime Day. Narwal is also matching said discount when you apply the promo code SUMNXU at checkout.

The Narwal’s spinning triangular mop pads do an excellent job of cleaning hard surfaces while offering some impressive smarts. The robovac / mop hybrid is capable of adapting the pressure of its mop based on the floor type, for example, applying more to tile and less to hardwood. The bot can also make cleaning “decisions,” including going back to mop up dirty floors if it detects they still need some work, and it’s even capable of detecting and cleaning dirt within its own mop pads.

The Narwal also has several other useful features. Equipped with two large four-liter water tanks, it mops longer than rivals like the Roomba Combo J9 Plus. It’s relatively quiet, too, with a disposable onboard bin that can compress dust so you don’t have to deal with a loud auto-empty dock. With 8,200Pa of suction power, it does a good job on most carpets, even if it’s not great with plusher material.

That being said, the Narwal lacks a camera, so its obstacle avoidance and navigation abilities aren’t the best. But as long as you keep your floors relatively clutter-free while cleaning, the Freo X Ultra should be able to navigate around small objects like socks just fine, leaving your floors spotless with minimal effort.
