These instructions are applicable to both bObsweep models. Follow the video or text descriptions to replace the disinfecting UV lamp on your automatic vacuum.
This walk through includes: opening bObsweep, removing the main board, replacing the UV lamp, and putting Bob back together.
You'll need a Phillips head screwdriver and a replacement UV lamp from bobsweep.com.
Flip Bob over and remove the main brush. Unscrew the holder, and lift the brush out. Keep all brush parts aside for reassembly.
Un-install the screws on around Bob's underside. They hold the cover together. (Highlighted Green)
There are two screw holes inside the brush compartment: one in the centre, one on the left end. (Highlighted Blue)
Remove both and keep apart from the main brush parts.
Depending on your model, there may be only 6 screws installed in the 7 holes of your bObsweep.
Flip Bob over carefully holding the cover together. Then, lift the cover up to reveal bObsweep's main board.
Remove three circuit plugs from the motherboard. Pinch the small white tab on the side of each and pull up.
- On the bottom left corner: a small connector with red, black and white wires. (Highlighted Red)
- One thick white wire that attaches on the right side of the previous connector. (Highlighted Yellow)
- On the top edge of Bob's motherboard: a wide multicoloured connector. (Highlighted Green)
- Detach the power inlet from the cover. Grip it and slide it out. (Highlighted Orange)
After opening bObsweep, you will see the main board in the center. To remove it, unplug 11 more circuit plugs. Press the tab on the side and pull up to detach.
Detach all of the motherboard's circuit plugs. Keep note of where each plug attaches for installation of the new one.
Next, un-install 3 screws. (Highlighted Pink)
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.
Keep all screws and parts removed from Bob. They will be needed later for re-assembly.
There are two screws which hold the UV lamp in front of Bob's left wheel. Un-install them, and lift the lamp up. (Highlighted Red)
Then, slide the UV lamp's small circuit board up and it will come out of its holder inside bObsweep.
There is also a plastic cover for the lamp which should stay inside Bob. If it pops out during the repair, lay it back in place under the lamp. The rougher side of should face down.
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.
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.
Reconnect all the circuit plugs you removed in the first step 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.
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.
There will be 3 empty spaces left on this row. Two will be filled when you connect the cover.
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)
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. (Highlighted Orange)
Slide the power inlet back into the 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.
This is what your finished product should look like:
There should be one empty space in the middle of the bottom row.
Put bObsweep's top back on, and align the edges precisely.
Install the screws you removed to start this repair, securing the cover together.
There are five along the edges of bObsweep's underside. (Highlighted Red)
Plus one or two more in the screw holes inside the brush compartment. (Highlighted Green)
Remember, your bObsweep model may have only one screw in the brush compartment. It should be installed in the far left corner close to the main brush's pin end.
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 main brush screw and you're done!
