Replacing Bumper - Bob PetHair Plus

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

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

Detach the cover and flip it over onto a flat surface.

Remove the 2 springs on either side of Bob’s screen and save them for later reassembly.

Remove the 4 screws securing the bumper to Bob’s cover.

Lift the bumper to detach.

Bob's bumper has 3 pieces: a large exterior piece, a small wired piece, and a plastic strip.

Lay down the large exterior piece first. Place the cover on top so the screw posts on the exterior piece protrude through the holes on the cover.

Lay down the small wired piece next. Make sure it lines up with the screw posts on the interior of the cover, and that no wires are compressed.

Lastly, clip the plastic strip to the front of the exterior piece.

Hold everything together as you replace all 4 screws securing the bumper to the cover.

Finally, replace the 2 springs on Bob’s cover. The curved edge hooks into a small slot on the bumper, while the straight edge hooks under a screw on the inside of Bob’s cover.

Now you’re ready to reconnect Bob’s cover.

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!
