eufy Omni C28

The dock stands 16.9 inches tall, 17.2 inches wide, and 13.9 inches deep. Plan a clear spot near an outlet, since it holds a 2.2 L clean tank, a 2.2 L dirty tank, and a 3 L dust bag.

The robot is 4.3 inches tall, so it slides under couches and cabinets with at least that much clearance. It also climbs thresholds and door sills up to 20 mm high between rooms.

The dock automatically empties the robot's 300 mL onboard bin into a 3 L bag, so you go weeks between bag changes. It also refills the robot's water tank mid-clean from the 2.2 L clean tank, so you rarely touch it.

Yes. It supports no-go zones and stores multi-level maps for up to 5 floors, so you can block off specific areas and let it clean the right rooms on each level.

It supports voice control through Amazon Alexa, Google Assistant, and Apple. You can start, stop, and direct cleanings hands-free through whichever platform you already use.
