Difficulty

Moderate

Steps

Time Required

20 - 45 minutes

Introduction

This guide explains how to remove the main brush motor from your Roomba.

Tools

Step 1

Place your Roomba upside-down on a hard surface.

If all you need off is the faceplate, skip all of the screwdriver-based steps, and just remove the dirt bin(step 7) and start from step 11 at the rear.

Step 2

While holding the side brush in place, use a Phillips #1 screwdriver to remove the 4.5mm screw from the center of the brush.

Step 3

Gently pull upwards on the brush to remove it.

Step 4

Rotate the Roomba upside-down so the bottom is facing towards you.

Step 5

Using a Phillips #2 screwdriver, remove the captive screws that hold the bottom plate in place.

Step 6

Carefully lift the bottom plate.
The battery is only secured in place by the bottom plate, and may fall out once the bottom plate is removed.

Step 7

Push on the dirt bin release button, and pull gently.

Might as well do this first, so you don’t dump dirt everywhere when flipping Roomba over.
