i have had the S5 for less than one month. Has worked great until it started saying something like “boot failure, it will take 5 minutes, please be patient.” It started doing this on its own over night and did it over and over. I have tried to hard factory reset and nothing. The machine has also been cleaned. There are no lights on the vacuum and I am unable to reset WiFi or factory reset. Will just try and keep saying there is a boot failure. It is also overly warm around the power buttons and front sensor. Very disappointed being less than a month old.
We are sorry for the trouble you are facing.
Did you try to turn off robot by pressing the power button for 3-5s when robot is not on the dock ?
