Eufy Robovac L70 dies while vacuming

Hi there,

My Robovac currently contains firmware 0.11.30. I am not aware how long ago this version is installed.
It vacuums my ground floor every night at 4:00. This task has been performed fine for a year or so. Every now and then the machine got stuck between objects, but generally it did the job, I asked it to do.

Currently the machine dies while doing the job. First I thought the battery caused it. But I monitored the machine while executing the job and found out the battery is filled at least 60% when the machine dies (middle of an area, no objects blocking the path).
It seems that the software is crashing and after that the machine switches off. The only way to get it started again is manually putting it on the charger. The machine reboots and shows a 60-% filled battery.
After this reboot an old layout is shown in the smartphone app.

I tried resetting the machine, without any luck.
I tries the machine on other (smaller) floors in my house. 3 testrunsit runs fine, 2 times it died on the job.

Anybody else experienced such behavior?
Is there a way to install a new (or older) firmware?
Other tips are very welcome…


How you did that?
Really the best is to disconnect the battery and reconnect it after 30 secs.
Otherwise you should contact the Eufy support.

Is it still under warranty?

I did not remove the battery. I can give that a go.

Formally yes. However, the company I bought it from is bankrupt. I had a really frustrating mail discussion with Eufy. They keep pointing to this company to take their responsibility. Eufy cannot understand the concept that a bankrupt company simply does not exist anymore. This is why I turned to this forum. I hope with tips from the community to get it fixed

Do that please.
My daughter and I swapped the left side brush motor of an 11S.
(our beloved “Old Willy”) and we cleaned the free wheel of the middle brush by removing that plastic cover.

We had fun as usual as we are an unbeatable tinkering team. :joy:

“Old Willy” luckily survived that surgery and he is doing his job now.
His third birthday will be in June.

I disconnected the battery for 10 minutes. After reconnecting the L70 still showed the same behaviour. It ran a few times in a smaller room. I moved it downstairs and let it run. This time the L70 died in action again. Same as before.

Anybody some more ideas? Or better, is there a new firmware underway the might solve this issue?

Thanks in advance

Seems you (we :smiley:) have nearly done everything.
It could be a faulty battery.
Do you have the possibility to check the battery with a battery tester?
But you should contact the support.
May be they have another idea and you could ask about a firmware.
