Ecovacs DEEBOT T50 Omni

The 3 L dust bag holds weeks of debris before swapping, and the 4 L clean and 4 L dirty water tanks last many mopping sessions. The dock also empties the robot's 260 mL bin automatically, so day-to-day upkeep is minimal.

The robot stands 3.2 inches tall, so it slides under sofas and cabinets with a few inches of clearance. Plan for the dock, which is about 21 inches tall and 13.8 inches wide, near an outlet.

It clears obstacles up to 20 mm, so it handles most door sills and transitions between hard floors and low rugs without getting stuck.

Yes. The mop lifts up to 9 mm when it detects carpet, so rugs stay dry during a combined vacuum-and-mop run. Smart Carpet Cleaning also boosts suction on carpeted areas.

You can set no-go zones and store maps for two levels through the app. Voice control works with its built-in assistant plus Amazon Alexa and Google Assistant.
