Shuts down

Hello I have an Efui 11. And have the following problem. The robot is fully charged at its station. When I turn it on, it sucks for about 20 to 30 seconds and then it goes into trouble. I cleaned it and tried to start it again. With the same result. He goes into disorder. Now I am finished with my Latin.
Question: What could be the problem?

Best regards
Oliver Kleisch

Hallo ich habe ein Efui 11. Und habe folgendes problem. Der Roboter ist voll geladen an seiner station. Wenn ich ihn an schalte, saugt er circa 20 bis 30 Sekunden und dann geht er in Störung. Ich habe ihn gereinigt und nochmal versucht ihn zu starten. Mit dem selben Ergebnis. Er geht in Störung. Jetzt bin ich mit meinem Latein am Ende.
Frage : Was könnte das Problem sein?

Mit freundlichen Grüßen
Oliver Kleisch

Hi, when my 11+ starts acting up, its sometimes needs the front sensors cleaned. Even if looks clean give it a quick cleaning. I’ve also had to reset the remote a few times/replace the batteries, and I have had to unplug the base, turn the robovac to off using the switch on the side of the unit. These 3 steps usually get it running again. If that doesn’t work I would contact support via their email. Make sure to tell them what troubleshooting steps you have already tried. Also have your serial number handy and a copy of your purchase order they may ask for all this.

Hello Oliver,
thank you following my advice to write your request in English.
If you solved the issues you have, please let us other RoboVac users know. :grin:

I use to clean the RoboVac after each cleaning job.
As Element321 mentioned the dust on the sensors at the front and at the bottom had to be removed properly
Also wheels and brushes may be adhered by hairs.

And at last, of course you are welcome to take further part in our community.

best regards
