Replacing Main Brush Motor - Bob PetHair Plus

To replace Bob's main brush motor, you’ll need a Phillips head screwdriver, a flat head screwdriver, and a new main brush motor.

Before starting any repair on Bob, turn his side power switch OFF.

Then, remove his dustbin.

Flip Bob over onto a flat surface and remove his main brush using the flat head screwdriver. Save all screws and parts for later reassembly.

Use a Phillips head screwdriver to remove the 6 screws on Bob's underside that hold him together.

Hold Bob's top and bottom together as you flip him onto his wheels. Grip Bob's cover from the back and lift up to expose his mainboard.

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

To detach Bob's cover completely, disconnect 4 circuit plugs:

  • 2 at the bottom of the mainboard
    • 1 on the far left
    • 1 with a thick white wire

  • 2 at the top of the mainboard
    • Disconnect the 2 center plugs

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

The main brush motor is found on Bob’s left side, in front of the left wheel. Grip the motor and slide it up.

Remove the motor's circuit plug from the mainboard.

Next, connect the new main brush motor to the mainboard. Push down firmly to ensure a secure connection.

Align the new motor’s edges with the indentations on Bob.

It should easily slide straight down when lined up correctly. Once in place, you’re ready to close Bob.

Reattach all 4 circuit plugs connecting Bob's cover to the mainboard:

  • 2 at the top of the mainboard

  • 2 at the bottom of the mainboard

Remember to slide the power inlet back into its space on Bob's cover.

Align the cover’s edges precisely. 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 Bob.

Then, flip Bob over onto a flat surface. Replace all 6 screws previously removed from Bob's underside.

Replace the main brush and dustbin before your next use and Bob is completely reassembled!
