Replacing Dustbin Contact Points - Bob PetHair

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

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.

To access the dustbin’s contact points, you will need to remove the wheel cover. You may move the main brush motor out of the way for better ease of access.

Remove the 6 screws securing the cover onto Bob:

  • 2 next to the mainboard

  • 2 on either side of the left wheel

  • 2 on either side of the right wheel

Once all 6 screws are removed, lift the wheel cover up and unplug it from the mainboard. Place it aside for now.

For better ease of access, you may place the left and right wheels aside, just be sure to keep their springs safely on-hand for later reassembly.

It may also help to prop Bob’s back up for the rest of the repair.

Remove 5 more screws to remove to access the contact points.

Lift up the plastic barrier and slide the contact points out of their spaces.

Follow the wiring to the correct circuit plug and unplug it from the mainboard. The circuit plug may be situated differently depending on your bObsweep model. Connect the contact points to the empty space.

Feed the wiring back underneath the mainboard, toward Bob’s back.

Place Bob’s contact points back in their spaces so that the black wire is on the left. Push down to ensure that each contact point sits flat in its space. The rest of the wiring should be fed toward Bob’s right wheel.

Hold down the contact points as you replace their holder. Align the holder with all of Bob’s screw posts without compressing the wiring underneath.

Make sure the contact points have not shifted out of place. Then replace all of the barrier’s 5 screws.

With the back of Bob still tilted up, replace the left and right wheels if you have removed them. Replace the two springs on top of the wheels.

Plug the wheel cover back into the mainboard.

Carefully align the cover with the screw posts on Bob. Make sure the springs on top of the wheels do not move out of place as you push the cover down.

When the cover lies flat against Bob, replace all of its 6 screws:

  • 2 next to the mainboard

  • 2 on either side of the left wheel

  • 2 on either side of the right wheel

Replace the main brush motor if you have removed it before you begin closing Bob.

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!
