I want to really like Robot vacuum but I'm having a bit of trouble being able to even use it. It doesn't seem to want to stay connected to WiFi. I have only tried it once to tested out in a single area of my home. It seemed to have cleaned decently, but there were some spots left with debris. However, it was only one time that tested it so i can't really rated accurately. I just need to figure out why it's getting disconnected from the WiFi.. I've had to deleted from the app and start over once already just to get it to reconnect. I don't want to have to do that everytime... Will have to keep trying...
