User Manual eufy ROBOVAC 15C MAX Wi-Fi Connected Robot Vacuum Cleaner

Is does not map, random clean, but the remote has an edge mode and it will follow around the house along the edges.

It has aa fall sensor and I was skeptical at first, but as long as you keep the front of the vacuum clean it won't fall over edges. Works really well.

It's working great on hardwood and ceramic. We live in ne Wisconsin and have plenty of sand. My wife loves it

If you want to operate the robovac through the eufyhome app, then you need the Wi-Fi. Or you could use the remote to operate it.

Yes as well as if it gets stuck as long as you have the app notifications turned on.

Don't know about Android, we have iPhones and the Eufylife app works and notifications work great!

The users can just let the RoboVac run its own. Also, the users can use the remote or app to control it.

The light will “breathe” on the dock, and it also tells you whether your Eufy is charging, cleaning, stuck, or returning home on the app.

And it is. I program this machine to run during the night while we are sleeping.

My yard is under construction before we add pavers and it looks like a beach. So I can tell you that it picks up sand quite well. Ours in now a fine powdery sand but a little more coarse.
