Replacing Main Brush Motor - Junior

To replace Junior’s main brush motor, you’ll need a Phillips head screwdriver, the flat-head screwdriver included in Junior’s box, and a new main brush motor.

Before starting any repair on Junior, turn his side power switch OFF and remove his dustbin.

Then, flip Junior over onto a flat surface and remove his main brush using the flat head screwdriver. Keep all removed screws and parts safely aside, as they may be needed for later reassembly.

Use a Phillips head screwdriver to remove the 7 screws on Junior’s underside that hold him together.

Junior’s cover is no longer secured, so hold the top and bottom together as you carefully flip him back onto his wheels. Grip Junior’s cover from the back and lift up to expose the mainboard.

Slide the power inlet down and tuck it somewhere safe to avoid compressing its wires.

To detach Junior’s cover completely, disconnect 4 circuit plugs.

Junior’s cover is now completely detached and can be set aside for the rest of the repair.

The main brush motor is found on Junior’s left side, in front of the left wheel.

Grip the motor and slide it up.

Then, grip the tab on the motor’s circuit plug and pull up to remove it from the mainboard.

Next connect the new main brush motor to the mainboard.

Align the new motor’s edges with the indentations inside Junior. It should easily slide straight down when lined up correctly.

Once in place, you’re ready to start closing Junior.

Reattach all 4 circuit plugs connecting Junior’s cover to the mainboard.

Remember to slide the power inlet back into its space on Junior’s cover.

Align the cover’s edges precisely. Then, flip Junior over onto a flat surface.

Ensure that no wires are compressed in the main brush compartment or visible at the edges of the bumper. If so, take a step back and lift the cover to tuck the wires into the appropriate spaces inside Junior.

Once the wires are all safely tucked away and Junior’s cover is aligned properly, reinstall all 7 screws previously removed from Junior’s underside.

Install the main brush and dustbin before your next use and Junior is completely reassembled!
