bObsweep PetHair Plus WPP56002 Troubleshooting

When bObsweep is at a ledge or moving along stairs, he tends to fall instead of stopping and turning

Wipe the sensors using a dry cloth, or dust them using compressed air. If Bob displays this Trouble Number while working on dark-colored carpet or patterned flooring, you may need to cover his sensors with blindfold stickers.

Remove two screws from each of the four sensors and set them aside. The wiring of the two outermost sensors pass under the mainboard and will need to be passed toward the front wheel. While keeping the plastic sensor covers in place, disconnect the sensors from the mainboard by pushing in the small tabs on the side of each circuit plug and pulling them up and out. Install the new sensors by plugging them into the mainboard, ensuring the wiring of the two outermost sensors are passed back under the board. Each sensor should be placed over the plastic sensor covers with the green side facing upward. Reinstall all eight screws across the four sensors.

When bObsweep nears a wall or corner he causes a collision instead of turning

Do a visual check on the translucent strip on Bob’s bumper. If it appears dirty or congested, wipe it with a clean, damp cloth. To ensure nothing is jammed under the bumper, gently tap it and use compressed air to clear it of debris.

On a flat surface, remove and set aside the two springs on either side of the screen. Remove the four screws connecting the bumper to the cover, and lift to disconnect the bumper, separating it into its three components: a large exterior piece, a small, wired piece, and a plastic strip. First, place the cover on top of the large exterior piece, ensuring its screw posts protrude through the cover’s corresponding hole. Next, install the new wired piece, the obstacle sensors, slightly lifting the bumper if needed. Again, ensure it is lined up with the screw posts so that it is not compressing any wires. Finally, clip the plastic strip flush to the front of the bumper. Secure the components together while reinstalling the four screws and replace the two springs so the curved edge hooks into a slot on the bumper and straight edge hooks under a screw inside the cover.

When bObsweep runs into a movement restricting object it fails to turn or correct its course

Slowly and carefully tap on Bob’s bumper to clear out any obstructions. Use compressed air to clear it of dust and debris. Press on both ends of the front bumper until you hear a tiny ‘click’ sound. If the bumper is not clicking on its ends, it is possible that one or more of Bob’s touch sensors has a broken arm and needs to be replaced.  Faulty touch sensors Remove and set aside the screw on each sensor and lift the sensors to extract them. Replace them with the new sensors, ensuring the red-wired sensor is on the left side and the black-wired sensor is on the right. Reinstall the screws and reconnect the cover.

When bObsweep’s power button is pressed, the screen does not power on.   

Remove and set aside the four screws on the underside of the cover that secure the screen. Lift the screen out, moving aside any wires as needed. Align the new screen facedown with the screw posts on the cover and reinstall the four screws once the screen lies flush.

When bObsweep is powered on, it does not move or paths incorrectly

Left or right wheel: Use the cleaning tool or compressed air to remove any dust or debris that may be jamming the wheel.

Front wheel: Remove debris congesting the front wheel using compressed air or the cleaning tool. If the congestion is not removable from the outside, disconnect the front wheel using a flat head screwdriver for leverage, and remove the obstruction.

Unscrew the six screws securing the wheel cover and remove it from the mainboard. The main brush motor and power switch may need to be moved to access these securing screws. Remove the wheel springs and set them aside so they are not misplaced. Extract the malfunctioning wheel and unplug it from the mainboard. Prop up bObsweep’s back a few inches and insert the new wheel. When plugging the left wheel into the mainboard, feed the wires around the bottom edge so they do not become stuck under the main brush motor. When plugging in the right wheel, first feed the wires around the closest screw post under the mainboard and pull them back out. Replace the two wheel springs and screw the wheel cover back on.

Either the main brush or side brush struggles to consistently rotate  

Remove the brush using a screwdriver and clear the housing and brush of hair, dirt, or other debris. Scissors or tweezers may be useful for removing hair or dust. Return the brush and screw it back into place.

For the main brush: Located in front of the wheel on the left side, slide the main brush motor up and out of its housing. Once out, grip the circuit plug tab and pull up to disconnect it from the mainboard. Press firmly to securely plug the new motor into the mainboard. Align the edges of the motor with the internal indentations for it and slide it straight down into place.

For the side brush: Remove the three screws securing the faulty motor and extract the motor. Place your new motor in line with the screw posts inside bObsweep and push down until it sits flush with bObsweep. Reinstall the three screws previously removed and rebuild bObsweep.

bObsweep doesn't power or charge when attached to charging dock. 

The electrodes can be wiped with a damp microfiber cloth to remove any dust, dirt, or oil. If the electrodes are corroded, use protective gloves and goggles while cleaning them. First, use a cotton swab to apply a weak acid such as lemon juice or vinegar which will neutralize the corrosive discharge. Next, use another cotton swab to supply isopropyl alcohol to clean any residue from the acids and the corrosion. Finally, wipe away any remaining dust or debris with a microfiber cloth and dust with compressed air to ensure no cotton fibers remain.

Ensure the charging station is positioned against a wall on a hard, flat surface, and there is at least 10 feet (3 meters) of open space to the front and 2 feet (0.6 meters) to each side.

Test the outlet with another device, like a phone charger, to verify there is power flowing to the charging station.

Open the battery compartment to check its battery connection. If the connection is secure, attempt to charge bObsweepsweep on its station. If this fails to resolve the issue, then charge bObsweepsweep with its charging adapter.

If bObsweepsweep charges with the adapter, then the charging station should be replaced. If connecting the adapter fails to wake the robot, then a new charging adapter is needed.

Lithium-ion batteries tend to lose power storage capacity over time. After 300 to 500 charging cycles, approximately two to three years of use, the battery’s functionality will be at its end and must be replaced. Remove the screw holding the small wire cover on top of the battery compartment, and delicately pull out the wires which connect the power switch to the battery through a circuit junction. Disconnect the battery from the power switch and lift off the top of the battery compartment. Remove the dead battery, replacing it with the new battery and return the top of the battery compartment. Reconnect the battery to the power switch and feed the circuit junction and wires back into the battery compartment. Return the small wire cover to its place and reinstall the screw securing it in place.

bObsweep’s UV Light is unresponsive. 

Remove the two screws securing the UV light in front of the left wheel. Lift the light’s circuit board out and extract it and the UV light. Install the new UV light by first placing the cover plate with its textured side down. Then place the bulb face down so it is aligned with the screw posts, reinstalling the two screws when it lies flat.
