There are two screw holes inside the brush compartment: one in the centre, one on the left end. Remove both and keep aside for reassembly.

There are five more screws around bObsweep's edges. Two are installed at the top and bottom, and one on the right end of the main brush.

Flip bOb back over so you can see the screen. Lift the cover up to reveal bObsweep’s main board.

2. One thick white wire that attaches on the right side of the previous connector.

3. On the top edge of bOb’s motherboard: a wide multicoloured connector.

Place the cover aside and begin your repair.

bObsweep standard and pethair have the same bumper attached to their covers.

There will be a wired piece for the wall sensors, then one large exterior cover for the bumper, and a small transparent plastic strip that clips on in the middle.

Place the large bumper piece underneath bObsweep’s cover, so the screw posts sit in the four holes around the cover’s front edge.

Lay the wired piece on top, so the screw holes line up with the screw posts. Make sure to line each one up preciseley, before installing all four screws.

Replace the two bumper springs on their posts.
