Replacing Wall Sensors - bObi Pet

For this repair, you will need a Phillips head screwdriver and replacement wall sensor.

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.

All of bObi’s wall sensors are plugged into a small circuit board on the underside of her cover. Unplug the circuit plug that corresponds to the wall sensor you want to replace.

Free the wires from the the black hooks along the inside of the cover.

Push out the sensor from the inside of bObi's cover, then feed the circuit plug out through the open space.

When that’s done, place your new wall sensor through the open slot.

Feed the wires back through the black hooks.

Lastly, plug the new sensor into the empty spot on the circuit board.

Now you’re ready to put bObi’s cover back together. 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.

Lay the 2 corner pieces down.

Reinstall the 2 screws on either side of bObi's dustbin.

Reinstall the screw located beneath bObi's front wheel.

Lastly, replace bObi's front wheel by turning it towards her bumper and pressing down.

Your repair is now complete!
