@danigrady, sorry for the inconvenience the Robovac 10 caused. Please be assured that we always stand behind our products and we are happy to assist you with an exchange if the problem turns out to be with it. Also, we provide 18 months warranty for our Robovac 10.
Would you let us know the error code (flashing/steady red indicator and how many beeps) when it stops? Different error codes indicate different causes. If you don't mind sending us a video showing the issue, it will be much appreciated and can help us locate the cause instantly.
And please contact us via our "firstname.lastname@example.org" so we can identify the issue at first, and our Robovac 10 is discontinued due to our marketing strategy, so we don't have the battery for our Robovac 10, but we will help you fix your Robovac issue in another way.
We appreciate your time and looking forward to your reply!
