For this repair, you will need a Phillips head screwdriver and replacement UV lamp.
First, flip bObi's power switch OFF.
Next, remove bObi's front wheel to access one of the screws holding her together. Turn bObi's front wheel towards her bumper and, using a screwdriver for leverage, grip the wheel firmly and pull it up.
Remove the screw located beneath bObi's wheel.
Detach bObi's dustbin and remove the 2 screws on either side of it.
Remove the 2 triangular corner pieces held down by these screws.
Pull the main brush compartment forward to expose the red fastener behind bObi's main brushes. Remove the 2 smaller screws holding the red fastener in place.
Lift bObi's brush compartment up and out. To detach her brush compartment completely, unplug it from bObi by pulling at the circuit junction.
Remove the 4 screws located beneath bObi's main brushes.
Remove the 2 screws securing the red contact point fastener onto bObi, and pull off the fastener.
Flip bObi back onto her wheels and lift her cover up. There are 2 circuit plugs which must be removed to separate bObi's cover completely: a yellow-wired circuit plug connected to the left side of bObi's mainboard, and a white-wired circuit plug connected to the center of bObi's mainboard.
Remove the circuit plug for the UV lamp on bObi's left side.
Then, remove 2 screws on the black circuit cover.
Lift the black cover up to expose the small circuit board for bObi’s UV lamp. Slide the circuit board up to remove.
Next, remove the 2 screws on the UV lamp.

Once the lamp lies flat, install its 2 screws.
Next, slide the new circuit board down into its holder and replace the black cover.
Tuck the lamp’s wires through the the indentations at the bottom of the cover before installing the 2 screws.
Now attach the lamp’s circuit plug to the mainboard and you’re ready to close the cover.
Reconnect the white-wired circuit plug to the center of bObi's mainboard and the yellow-wired circuit plug to the left side of her board. Press each circuit plug firmly until they lock in their holders.
Carefully replace bObi’s cover. Make sure its edges align precisely before laying down the contact point fastener and reinstallling its 2 screws.
Next, reinstall the 4 screws located beneath bObi's brush compartment.
Reattach bObi's brush compartment.
Line up the red brush fastener on bObi and replace its 2 smaller screws.
