A step-by-step guide to replacing the side brush motor on bObsweep Standard or Pethair. Follow the video or multimedia directions in order to open up bObsweep, remove and replace the side brush motor, then close your vacuum.

Step 1: Remove BObsweep's Cover Screws

Flip Bob over and remove the screws on the underside. They hold the cover together.

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.

Remove the main brush. Unscrew the holder, and lift the brush out. Keep this screw separate from the others.

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

Note: Depending on your model, there may be 6 or 7 screws installed on bObsweep.

Step 2: Detach the Cover Circuit Plugs

Flip bOb back over so you can see the screen. Lift the cover up to reveal bObsweep’s main board and detach the power inlet from the cover. Grip it and slide it out.

Remove three circuit plugs from the motherboard. Pinch the small white tab on the side of each circuit plug and pull straight up to detach from the motherboard.

1. On the bottom left corner: a small connector with red, black and white wires.

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.

Step 3: Remove the Main Brush to Expose the Motor

Detach all the circuit plugs from the main board. Firmly pinch the small white tab on the side of each plug, then pull upward to remove.

There are three screws that secure the main board inside Bob. (Highlighted Pink)

Remove all the screws, then lift the main board straight up and put aside.

Step 4: Remove the Side Brush Motor

Once the main board is removed, you will see the side brush motor in front of Bob's right wheel.

Uninstall the three screws holding it inside bOb.

Lift up and replace with your new motor.

Note: Make sure the side brush has been removed before changing the motor.

Step 5: Install the New Motor

Place the new motor in the open space, with the brush attachment facing down.

Ensure it sits flat, and aligns with the screw posts in Bob.

Install the three screws removed previously, then replace the main board.

Step 6: Install the Main Board

Place the main board back in bObsweep. Make sure the holes in the main board align with the screw posts on Bob.
Install the three screws to secure the main board. Then, attach all the circuit plugs correctly.

The order along the motherboard’s left edge from the top down is:

A small yellow and black circuit plug.

The main brush motor's circuit plug which has two pairs of twisted wires, one red and white, the other pink and black.

A wider, multicoloured circuit plug which is attached to bObsweep’s left wheel.

Finally, a small circuit plug with black and blue twisted wires.

Step 7: Connect All the Circuit Plugs

The order from left to right along the bottom ledge should be reconnected as follows:

A small circuit plug with red, black, white, and brown wires.

A small yellow-wired plug.

A small black and orange-wired circuit plug.

A circuit plug with multicoloured wires and a wide base which connects to Bob's right wheel.

Note: There will be 3 empty spaces left in this row. Two will be filled when you put the cover back on.

At the top of the motherboard’s right edge is a wide, red, black, and blue circuit plug. (Highlighted Pink)
Beneath that is a smaller plug for Bob’s power inlet with orange and black wires. (Highlighted Green)

Plug each one into the motherboard in the suitable slot.

There are two wide, multicoloured circuit plugs that attach to the top edge of the motherboard. One was removed to detach bObsweep’s cover, so the space will stay empty for now. The other plugs in on the right side of the open space. (Highlighted Orange)

Step 8: Connect the Cover

Slide the power inlet back into its space on bObsweep’s cover.

Attach the circuit plug with multicoloured wires, to the top right edge of the motherboard.

Attach the smallest circuit plug in the lower left corner of the motherboard.

Attach the all-white circuit plug to the bottom of the motherboard, on the right side of the previous plug.

Note: There should be one empty space in the middle of the bottom row.

Step 9: Secure the Cover

Lay bObsweep's top down and align the edges precisely.

Use a Phillips head screwdriver to re-install the screws you removed to start this repair, so the cover is sealed together.

There are five screws along the edges of bObsweep's underside. Plus two more in the screw holes inside the brush compartment.

Note: Depending on your bObsweep model, there may be only one screw in the brush compartment.

Step 10: Install the Main Brush

Re-install the main brush before setting bObsweep to clean again.

  1. Attach the end piece first.
  2. Put the square end in the square space inside bObsweep, then lower the brush in place.
  3. Install the screw securely.
