Roborock Qrevo CurvX

It empties into a 2.7 L bag, refills the robot's water, and cleans its own base, so most homes go weeks between hands-on upkeep.

At 3.1 inches tall, it slides under most sofas, beds, and cabinets with ease.

It clears obstacles up to 40 mm, so it handles most door sills and transition strips between rooms.

It washes the mop with 176°F hot water rather than auto-dispensing detergent, so you add cleaning solution yourself if you want it.
