Trouble Messages

Oops! I feel there's something funny going on with my ________.

When Junior is experiencing some difficulty, he will notify you by displaying on his screen “Oops! I feel there’s something funny going on with my:” along with the name of the part having an issue.

If after attempting the suggested solutions Junior’s problem persists, you may want to perform a home checkup test on him. You may also contact our customer care center at 1-888-549-8847 or Our business hours are Monday – Friday 9 am – 5 pm, PST.

Edge Sensors

The edge sensors are blocked or dirty. Junior’s four, oval-shaped edge sensors are located on his underside, near his bumper.

What to do:

1. Clean the sensors using a clean, dry cloth or compressed air.

2. If Junior is continually having trouble with his edge sensors while working on dark colored carpeting, you may need to deactivate them.

To deactivate Junior’s edge sensors:

1. Hold down the CHECKUP button on Junior’s cover. The 4 bars above CHECKUP will then flash on Junior’s screen.

2. After the bars flash 7 times and remain still, release the CHECKUP button.

Caution: When you deactivate the edge sensors, Junior will not detect stairs or sharp drops.

Touch Sensors

There is a small piece of debris trapped underneath Junior’s bumper that is interfering with his touch sensors.

What to do:

1. Slowly and carefully tap on Junior’s bumper to force the obstacle out.

2. Use compressed air to clear out dust and debris trapped underneath the bumper.

3. Press the corner ends of the bumper until you hear a tiny “click” sound. If the bumper is not clicking on its ends, the touch sensors may need to be replaced.

Left Wheel

Something is blocking the left wheel.

What to do:
1. Use the cleaning tool or compressed air to remove any dust or debris that may be jamming the left wheel.

Right Wheel

Something is blocking the right wheel.

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

Main Brush

The main brush is unable to move freely.

What to do:

1. Remove the main brush using a flat head screwdriver, and clean it thoroughly from end to end.

2. You may use a pair of scissors to cut hair or thread wrapped around Junior’s brush, or a pair of tweezers to remove congestion from the square metal indentation where the main brush is held.

​If Junior has trouble cleaning on shag carpet or rug, you may remove his main brush and allow him to vacuum without it.

Wall Sensors

The wall sensors are blocked or dirty.

What to do:

1. Do a visual check on the transparent strip on Junior’s bumper. If it is too dirty for you to see what is behind it, wipe it with a clean, damp cloth.

2. To ensure nothing is jammed under the bumper, gently tap it and use compressed air to clear it of debris.


Junior’s dustbin is not properly installed, or the metal contact points on the dustbin’s bottom are dirty.

What to do:

1. Remove Junior’s dustbin and empty it.

2. Turn the dustbin around and gently wipe the two metal connectors on its bottom.

3. Lastly, clean the metal contact points in the space inside Junior where the dustbin is inserted.

Power System

Junior's battery is disconnected or has absolutely no juice left.

What to do:

1. Check Junior’s battery connection.

2. Place Junior directly onto his charging station and allow him to charge for a few hours.

If this fails to wake him, then Junior may need a new charging station.

What to do:

1. Unplug the charging station and plug the adapter directly into the inlet on Junior’s side. Allow him to charge for a few hours.

If connecting the charging adapter to Junior fails to wake him, he likely needs a new one.
