Replacing Bumper - Bob Standard

For this repair, you will need a Phillips head screwdriver and replacement bumper.

Make sure Bob’s side power switch is turned OFF and flip him over onto a flat surface. Remove the screw securing Bob’s main brush in place.

Remove Bob’s main brush to access and remove the screw located beneath it (depending on Bob's model, there may be 2 screws).

Remove the 5 screws lining Bob’s underside.

Flip Bob back onto his wheels and lift his cover up. Depending on your Bob's model, you may need to remove 3 or 4 circuit plugs to detach the cover completely. Pinch the small white tab on the side of each circuit plug and pull upwards to remove.

For older versions of Bob, you must remove 3 circuit plugs from the mainboard:

For newer versions of Bob, you must remove 4 circuit plugs from the mainboard:

Slide Bob’s power inlet out and place the cover aside.

Remove the 4 screws holding Bob's bumper in place (the screw on the far left is hidden inside a screw post).

Remove the two spring pieces inside Bob’s cover before detaching his bumper.

Bob’s bumper is composed of an inner wired piece and a large exterior cover.

You may now install your replacement bumper parts. Place the large bumper piece underneath Bob’s cover so its screw posts align with the four holes around the cover’s front edge.

Lay the wired piece on top so its screw holes line up precisely with the screw posts on Bob’s outer bumper piece.

Replace all 4 screws lining the bumper's edge.

Lastly, replace the bumper's 2 springs.

Now you’re ready to put Bob’s cover back together. First, reattach all the circuit plugs you removed to separate Bob's cover. Press down on each circuit plug to ensure it securely locks in place.

For older versions of Bob, reattach 3 circuit plugs to the mainboard:

For newer versions of Bob, reattach 4 circuit plugs to the mainboard:

Before closing Bob's cover, slide his power inlet back in its place.

Carefully realign the edges of Bob’s cover and flip him onto his back. Replace the 5 screws on his underside to seal his cover together.

Replace the 1 or 2 screws located beneath Bob's main brush.

Place the main brush back in its compartment. Attach the end piece first

and align the square end with the square-shaped notch inside Bob.

Lastly, replace the screw securing Bob's main brush in place and your repair is complete!
