Common fix for short runtime, pulsing, or repeated charging errors.
iRobot Roombas are the gold standard for robot vacuums, but they rely on an array of sensors that can easily get dirty or jammed. When your Roomba stops and says “Error,” followed by a number, it’s usually trying to tell you that one of its mechanical parts is stuck or a sensor is blocked by dust.
Most Roomba errors are maintenance-related and can be fixed with a few minutes of cleaning.
What This Error Means
Roombas use a voice prompt or the iRobot Home app to announce errors.
- Mechanical Errors (1, 2, 5, 9): A wheel, brush, or bumper is physically stuck.
- Sensor Errors (6): The cliff sensors are dirty and the robot thinks it’s about to fall down stairs.
- Communication Errors (14): The robot doesn’t “feel” its dust bin or filter.
Common Roomba Error Codes
| Error | Meaning | Severity | Fix |
|---|---|---|---|
| 1 | Left/Right wheel stuck | Moderate | Clear debris from wheels |
| 5 | Right wheel jam | Moderate | Inspect wheel module |
| 6 | Cliff sensor error | Low | Wipe sensors with a dry cloth |
| 9 | Bumper stuck | Low | Tap bumper to loosen |
| 14 | Bin not detected | Low | Reseat bin or clean contacts |
Step-by-Step Fix
1. Resolving Error 1 or 5 (Wheel Jam)
If your Roomba is spinning in circles or won’t move:
- Flip the Roomba over.
- Push the wheels up and down several times to check for spring tension.
- Look for hair, carpet fibers, or string wrapped around the axle. Use scissors to carefully cut away any debris.
- Spin the wheels by hand. They should spin with a small amount of resistance. If one is locked, the wheel module may need replacement.
2. Fixing Error 6 (Stuck on a Cliff)
This error happens when the sensors on the bottom of the Roomba are too dirty to see the floor.
- Flip the Roomba over.
- Locate the 4 to 6 rectangular “windows” around the front edge. These are the cliff sensors.
- Wipe them with a clean, dry microfiber cloth. Do not use water or cleaning chemicals.
- Pro Tip: If you have dark or black rugs, the Roomba may trigger Error 6 because it thinks the black color is a “drop-off.” You can buy “Cliff Sensor Covers” to fix this if you don’t have stairs.
3. Fixing Error 9 (Stuck Bumper)
If the Roomba thinks it’s hitting a wall when it’s in open space:
- Briskly tap the front bumper several times.
- Look for any debris (like a small pebble or piece of plastic) wedged between the bumper and the main body.
- If the bumper feels “squishy” or doesn’t click when pressed, a spring may have popped out inside.
4. Resolving Error 14 (Bin Detection)
This error means the Roomba doesn’t know its dust bin is attached.
- Remove the bin.
- Clean the gold contacts on the back of the bin and the corresponding pins on the Roomba body with a dry cloth.
- Check the filter. If the filter isn’t pushed in all the way, the bin won’t seat correctly.
- Press the bin release button and firmly click the bin back into place.

When to Call a Professional
Roombas are modular, meaning you can replace almost every part with a screwdriver.
- Battery Issues: If your Roomba dies after 5 minutes of cleaning, you need a new battery ($30–$50).
- Loud Grinding Noise: This usually means the cleaning head module (the gears that spin the brushes) is stripped. You can buy a new module and swap it out in 10 minutes.
- Dead on Base: If the Roomba won’t charge even after cleaning the charging contacts on the base and the robot with a magic eraser, the charging base has likely failed.
