It does not recognized the contacts of the docking station. It still search and find the docking station well, but search endless the loading contacts.

I'm still good in electronics but do not have any schematics and don't kow any about the firmware/programms of a lot of microcontroller build in.

From the beginning it worked well and after some time was problem in navigation.

It looks like that: move 20-30cm stop and go back about 3cm, turn 90st. and repeat.

Sometimes work good for 1 minute and then again fail to this state.

I try test mod and all sensors look fine, motors are OK too.

My SR8855 suddenly died when it was out on a cleaning run one day.

It have had the problem that after the first start it goes back to the charging station after just a few seconds to load up fully and then it goes off and does the whole run.

I have thought it was the battery being bad and now one day it suddenly stopped and went completely black. When I manually put it in front of the charger, the charger beeps and can find the cleaner but the cleaner keeps being black.

I have taken it apart, there is around 3v coming out from the battery and I have tried to look at the on/off button, as some others have had problem with, and it is also 3v coming though that button when I put it as On.

I am not so great to understand a electrical schematic so I do not know what to else try to troubleshoot with a multimeter. I couldn't find any burning marks either.

Will add some pictures, cheers!

I have an issue with my SR8895 vacuum robot.

During some weeks, the robot failed intermittently, the count down is ok, but after it the robot is crashed, no response from the touch or remote control, only the first battery led is on.

Even with a fully charged battery only the first battery led is on.

Once the robot is crashed, I measure the 5v rail and I saw that the pic controller tries to reboot the robot by cutting down the +5v. The robot restarts and the count down pass and the robot stuck again. the robot reboot around each 1 minutes.

Until now, I was using as workaround this two step: disconnect the PSU and wait for a while.

But today I seem that this workaround is no more efficient.

Do you have an idea of the issue or do you have the schematics?

I will very helpful for me.

Thank you

PS: I have a multimeter and soldering tools

I think some of voltage regulators died.

Looking for solution or full schematic.
