Replacing Left or Right Wheel - Bob PetHair Plus

To replace Bob's left or right wheel, you’ll need a Phillips head screwdriver, the flat-head screwdriver included in Bob's box, and a new left or right wheel.

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.

You may wish to lift and move the main brush motor and power switch out of the way to reach the screws securing the wheel cover onto Bob.

Remove the wheel cover's 6 screws:

  • 2 screws are next to the mainboard

  • 2 are on either side of the left wheel, one above and one below

  • 2 more screws are on the right wheel, one above and one below

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

Be sure to keep the wheel’s springs safely on-hand for later reassembly.

Place the new wheel in the open space. You will have to prop up Bob's back a few inches to insert the wheel.

If you are replacing the left wheel:

  • Feed the wires around the edge of Bob's bottom before attaching the circuit plug to the mainboard.

  • Ensure the wires are not stuck under the main brush motor or sticking out of place.

If you are replacing the right wheel:

  • Feed the wires around the closest screw post underneath the mainboard.

  • Pull the wires back out before attaching the circuit plug to the mainboard.

Replace the 2 springs on top of the wheels.

Plug the wheel cover back onto the mainboard.

Then, carefully align the cover with the screw posts on Bob. Clear the area of any wires than may become compressed underneath the wheel cover. Make sure the springs on top of the wheels do not move out of place as you push the cover down.

Install all 6 screws previously removed from the wheel cover:

  • 2 just behind the mainboard

  • 2 around the left wheel

  • 2 around the right wheel

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. Reinstall all 6 screws previously removed from Bob's underside.

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

    Does working on this void the warranty?
