The full-featured eufy Clean app offers fine-grained control of every setting, allowing you to customize nearly every aspect of the eufy E20’s operation. See this video walkthrough of the app.

To create a map, you can select Fast Mapping, where the robot vacuum goes through your home using its LIDAR sensor, or Clean + Mapping, where it maps while cleaning simultaneously. You can see the robot vacuum’s path in real time when it’s mapping. Once a map is created, you can create another map on another level of your home and add no-go zones or virtual walls. You can also divide, merge, hide, or name rooms as well as add carpeted sections.

You can set up to 10 schedules for vacuuming, and repeat a schedule on certain days. On each schedule, you can set the suction level and the number of cycles for each cleaning task, and also select a certain room, zone or the entire house for scheduled cleaning events.

You can set the auto-emptying frequency of the robot vacuum from every 15 minutes of cleaning to every 60 minutes. You can set the auto-emptying cleaning mode from Normal to Deep. You can also set whether the robot vacuum will auto-empty after every use of the built-in handheld vacuum. 

The app tracks cleaning history as well, showing the total number of times the robot vacuum has operated, the total area cleaned, and the total operating time of the vacuum. There’s also data on individual operations: a map of its path, the area, the cleaning time, a timestamp, and the robot vacuum’s status at the end of an operation. You can also track the remaining lifetime of each replaceable component. 

You can toggle the BoostIQ setting on or off, which will automatically increase the suction of the robot vacuum when it encounters carpet, though this reduces battery life. There are manual controls for initiating cleaning, returning the robot vacuum to the docking station, and for moving the vacuum in a particular direction.

So that it won’t disturb you, the robot vacuum can be set to No Resume, meaning it will not resume cleaning after it recharges, or Silent Running, where it keeps its suction as low as possible to minimize noise. You can also set the Child Lock to deactivate the vacuum’s physical buttons. The app allows you to set the measured units. There is also Find My Robot, which you can select if the vacuum is lost.

The only feature you can’t alter is the obstacle avoidance setting. The robot vacuum also doesn’t mark obstacles on the map, even though it does a good job of recognizing and avoiding them.
