Roborock Qrevo S Pro

The dock's 2.7 L dust bag holds weeks of debris before it needs changing, and it empties the robot's 330 mL bin automatically. The 4 L clean water and 3.5 L dirty water tanks also last many sessions between refills and dumps.

At 3.8 inches tall, the robot slides under many couches, beds, and cabinets. The dock is larger at 20.4 inches tall and needs clear floor space near an outlet.

Yes. It climbs obstacles up to 20 mm, so most door sills and transition strips between rooms are no problem.

It washes the pads at 167°F, then air-dries them at 113°F to help prevent mildew and odor. Auto tank refilling also keeps the onboard water topped up mid-clean.

It works with Amazon Alexa, Google Assistant, and Apple. You also get no-go zones, smart carpet cleaning, and 3D structured light obstacle avoidance through the app.
