I have a robovac 11 and the device no longer has a light if I plug it in to both the charging base and directly to the device. If I plug into the device directly I get a 2-tone beep like the charging beep but not the positive confirmation final beep like it used to.
It also doesn’t activate the LED at all.
Sometimes I’ve gotten a 4 beep error code as well but again, the LED doesn’t light up.
I’ve tried disconnecting the battery but that hasn’t made a difference.
I’m wondering if this is a sign of the battery being dead or if there’s something else amiss? I’d rather buy a new battery over a new device if I can help if we the performance of the device before this was great.
