Ecovacs Deebot 900 Motherboard Replacement

Difficulty

Very difficult

Steps

Time Required

5 - 15 minutes

Introduction

The motherboard is a crucial aspect to controlling the Ecovacs Deebot 900. Unfortunately, the motherboard is easily fried if the robot accidentally vacuums water and may need to be replaced. Use this guide to replace the motherboard in the Ecovacs Deebot 900.

Tools

Step 1

Using a Phillips #00 screwdriver, remove the eight screws on the bottom edge of the bumper.

Step 2

Remove the black strip on the bottom of the bumper.

Step 3

Carefully lift up the bumper untill it pops out of place.

Step 4

Disconnect the two cables connecting the bumper to the body of the Deebot.
Remove the front bumper from the device.

Step 5

Using a Phillips #00 screwdriver, take out the six screws around the perimeter of the bottom case.

This was actually to toughest part. I have a Deebot T9+ and it is slightly different (not much) and it is always a bit scary when you have to remove "plastic fixeners"

Disconnect the two cables and remove the bottom case from the device.

This step is difficult, but takes some time and patience, keep pulling. I managed to open it by pulling from the front part which was previously covered by the bumper

If anyone is keen to see how to replace a motherboard on the Ecovacs Deebot Ozmo 950 (same for T5), here's a video guide on how I did it: https://youtu.be/jlsOlYYFl8k. If the link doesn't work, search YouTube for "Ecovacs Deebot 950 Stopped Working! How to replace MOTHERBOARD and make it work again!!". The motherboard replacement cost me $90 AUD from AliExpress. Basically, my Deebot 950 was no longer charging despite me installing a new battery replacement, and when I'd turn on the robot, it would back out of the charging dock and then simply turn off (deactivate), and there was nothing I could do. The motherboard is the problem. I replaced it myself and now it works like brand new again. Hopefully my video guide helps others. I was literally on the verge of throwing this cleaner into the rubbish thinking it no longer works.... but gave it one last attempt to fix and glad I did! :)
