i bought a batrie to my roombai7 that you said that was compatible but my roomba said that not ricognize

I'm trying to figure out whether I'm dealing with a hardware fault or a software/firmware bug on my Roborock S7 Max Ultra.

Firmware: v02.26.80 (currently up to date, per the app)

The problem: After the robot finishes a cleaning cycle, it does not automatically empty its bin into the dock. This happens regardless of whether the auto-empty setting is on "Smart" or "Max."

What works fine:

If I manually trigger emptying from the app, it works perfectly every time. Even when the robot's onboard bin is completely packed full (mostly dog hair), the manual empty cycle pulls everything through into the dust bag in the dock with no issues.

What doesn't work:

• The automatic emptying after a cleaning run simply never triggers on its own.
• The bin indicator in the app never turns red/full, even when the bin is genuinely packed solid. The robot will happily keep cleaning with an already-full bin instead of stopping or flagging it.
• Eventually I do get an "empty ASAP" notification, but given the above, I suspect that's just timer-based (e.g. "X days since last empty") rather than tied to an actual full-bin reading.

Has anyone dealt with something similar? Is there a known sensor (e.g., bin-full sensor or dock contact sensor) that could cause this exact symptom, or is this more likely a bug that needs a factory reset or re-pairing to fix?

Any troubleshooting tips or shared experiences would be appreciated.

The clean water refill function is triggering an error and stopping the machine.

The machine runs for about three minutes before signaling to refill the clean water tank—even though it is already full—and then stops. If restarted, it resumes operation but again signals to refill the clean water after about three minutes; this cycle repeats continuously.

Thanks

I disassembled one of them because I had an issue with smoking and a burning smell. It turned out it needed to be cleaned and a bit of oil needed to be applied to the top bearing. The first unit that I disassembled was missing a screw on the motor housing - but did not know at the time. When I started assembling the unit, I thought was going crazy because I was one screw short. I ended up using another similar size screw I found in my workshop.

It wasn't until today when I though I would do some preventative maintenance on the second Shop-Vac that I noticed that this one was also missing a screw - in the same place! Someone not doing their job properly? Very strange indeed.

I have cleaned all parts
