Робот-пылесос сломался

Hello, my Sweeva 6000 is charging: it's flashing as expected, indicating it's charging, and the app says it's charging, but the charging indicator in the app keeps dropping . I've cleaned the contacts, turned it off and on, but it doesn't help; the battery percentage in the app keeps dropping.

I also noticed that it starts charging at the docking station, but it doesn't always start charging. It keeps driving away and then driving back in, and so on. When I manually dock it, it supposedly starts charging, but it doesn't... the charging percentage in the app just keeps dropping.

I changed the power supply at the docking station, but it still won't charge.

Is the battery dead and needs to be replaced, or is there something else I can do? Has anyone encountered this problem, and what did they do? Is it worth taking it in for repair, or will they charge me as much as a new one?
