These instructions are applicable to both bObsweep models. Follow the video or text descriptions to replace the UV lamp on your automatic vacuum.
Step 1: Open Up Bob
Flip Bob over and remove the 7 screws around which hold the cover together.
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.
Remove the main brush. Unscrew the holder, and lift the brush out. Keep this screw separate from the others.
Note: Depending on your model, there may be only 6 screws installed on bObsweep.
Step 2: Detach the Cover
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 release each 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 All Wiring From the Main Circuit Board
After opening bObsweep, you will see the main board in the center. To remove it, unplug 11 more circuit plugs.
Detach all of the motherboard's circuit plugs. Keep note of where each plug attaches for installation of the new one.
Step 4: Remove the Main Board
Next, un-install 3 screws.
There is one in the centre of the motherboard, near the multicoloured plug for Bob’s left wheel.
The second is close to the top right corner.
The third is near the bottom right edge.
Lift the main board straight up to expose the UV lamp.
Note: Keep all three screws. They will be needed later while installing the replacement main board.
Step 5: Remove the UV Lamp
There are two screws which hold the UV lamp in place. Un-install them, and lift the lamp up.
Then, slide the UV lamp’s small circuit board up and it will come out of its holder inside bObsweep.
Step 6: Install the UV Lamp and Circuit Board
If any pieces come apart, put them back in the correct order. Ensure the clear plastic lamp cover sits so the rougher side will be on Bob's outside.
Place your new lamp in the open space and install the two screws you removed previously.
The circuit board will slide straight down into the holder.
Step 7: Replace and Secure the Main Board to Bob
Replace the main circuit board. Make sure it lies flat on top of the screw posts inside bObsweep.
Install the 3 screws you removed previously.
All the circuit plugs you removed in the first step must be reconnected in the correct spaces.
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 8: Reconnect All Circuit Plugs on the Main Board
The order from left to right along the bottom ledge should be reconnected as follows:
A circuit plug with multicolored wires and a wide base which connects to Bob's right wheel.
A small black and orange wired circuit plug
A small yellow wired plug.
A small circuit plug with red, black, white, and brown wires.
Note: There will be 3 empty spaces left on 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.
Beneath that is a smaller plug for Bob’s power inlet with orange and black wires. Plug each in the suitable slot.
There are two wide, multicoloured circuit plugs that attach to the top edge of the motherboard. One attaches to bObsweep’s cover, so the space will stay empty for now. The other plugs in on the left side of the open space.
Step 9: Connect the Cover's Circuit Plugs to the Main Board
Slide the power inlet back into the space on bObsweep’s cover.
Attach the widest circuit plug with multicoloured wires, on 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, in the centre of the row.
Put bObsweep's top back on, and align the edges precisely.
Step 10: Close and Secure Bob's Cover
Use a phillips head screwdriver to reinstall the screws you removed to the start this repair, so the cover is sealed together.
There are five along the edges of bObsweep's underside. Plus one or 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 11: Install the Main Brush
Re-install the main brush before setting bObsweep to clean again.
- Attach the end piece first.
- Put the square end in the square space inside bObsweep, then lower the brush in place.
- Install the screw securely.
