Roborock Saros Z70

At 3.1 inches tall, it slides under many couches and cabinets. It also climbs obstacles up to 40 mm, so most door sills and floor transitions between rooms are no problem.

It uses an extendable side brush and an extendable mop that reach out toward walls and edges. Combined with its edge focus, this covers spots a fixed-brush robot would miss.

The dock empties the robot's 180 mL bin into a 2.7 L dust bag and holds a 4 L clean water tank plus a 3 L dirty water tank. These last weeks of normal use before you refill or empty them.

Yes. The dock auto-washes the mop pads with 176°F hot water and air-dries them at 131°F, which stops the damp, musty odor that builds up on unwashed pads.

It works with a built-in assistant plus Amazon Alexa, Google Assistant, and Apple. You also get no-go zones, multi-level maps for up to 4 floors, and smart carpet and dirt detection.
