Disassemble purei9 in order to fix stuck main brush error

borilboril Member

Hello,
I experienced issues with brush stuck error, so I had to dissemble my purei9 in order to fix this. I'm attaching few pictures here and will try to explain as best as possible how to reach to the main brush gear. May be next time I'll create a video.
First you have to remove the bumper:

You can easily free it from both left and right edges. You have to push the bumper from the back side of the robot to the front and gently to the side. View of the left side of the robot with bumper removed and also main brush gear cover removed.

View of the right side of the robot with bumper removed and side brush motor & gear removed

main brush gear cover in order to remove it you have unscrew few screws. I took a picture of the 4 bigger ones 2 of them are below control board of the robot.

Side brush motor & gear removed from the robot.

One of the 4 big screws is holding the side brush mechanism attached to the robot.

Side brush gear cover removed - you will need T10 torx screw for those screws.

I cover the camera's lens with a napkin to avoid scratches and you can see the right laser.

Here is the control board where are the LEDs, USB connector and buttons are located.

Here is close picture of connector which attach camera board with the control board.

Another of the same connector and you can see that I had to lift the plastic which is holding the control board in place with 4 little screws.

Picture of the two sets of torks screws - big one ( 4 of them in total) and little ones I didn't count them which are T15 and also we have 3 screws T10 holding side brush gear cover.

I tried to picture how bumper is attached to the front of the robot

Another bad angle of the same assembly - it is every easy to reattach the bumper but it did me very hard time until I manage to remove it initially.

Here is a picture of the one and only little T15 screw located under the control board it is located in the middle of the front part of the robot.

Here is another big T15 screw holding main brush cover on the left side of the robot.

Here is picture of the main brush gear belt.

Here is the location of the big T15 screw under the control board on the left side of the robot ( near the connector of the both boards)

Here is the location of the big T15 screw under the control board on the right side of the robot ( near the speaker of the robot)

Finally purei9 is working :)

I'll be glad if someone tell me how I can remove the back cover of the robot.

    Can anyone give some additional tips on how to remove the bumper?

    The sides are easy to detach from the pins, but it seems to be stuck in the front.

    Any help will be appreciated.

    You have to force the bumper to go up and then to pull from the front because of two big clips ( see the red arrows )
