Troubleshooting
Robot Vacuum Error Codes Explained
Error codes are brand- and model-specific, so a number that means "brush jammed" on one robot can mean something else on another. Here is how to decode yours safely.
Quick answer
Find the code in your model's manual or the maker's support page and follow the listed fix. Common categories are brush or wheel jams, sensor problems, a missing bin or filter, cliff detection and battery faults.
Why codes are not universal
Manufacturers assign their own numbers, and even models within a brand can differ. Do not rely on a code list from another model.
Common categories
| Category | Typical cause | First thing to check |
|---|---|---|
| Brush or roller | Wrapped hair or debris | Clear the brush roll |
| Wheel | Hair around axles or stuck wheel | Clean the wheel and axle |
| Cliff or bumper sensor | Dust or a dark floor | Wipe sensors |
| Bin or filter | Bin not seated or filter missing | Refit the bin and filter |
| Battery or charging | Contacts dirty or battery worn | Clean contacts; see won't charge |
| Wi-Fi or app | Network problem | See Wi-Fi troubleshooting |
How to find your code
- Check the app's notification or history screen.
- Look up the model's manual.
- Search the manufacturer's support site, not a third-party list.
Before you contact support
- Restart the robot and clear the obvious: brush, wheels, sensors, bin.
- Note whether the error appears in the same place or randomly.
- Check the app for a firmware update.
If the error returns
Note the code, model and what the robot was doing, then contact support. Repeated hardware errors may be covered by warranty. If the robot restarts over and over before it is ready, or circles instead of finishing a clean, see navigation loop vs boot loop to tell them apart.
Frequently asked questions
Can I clear an error by restarting?
Sometimes. If it returns, follow the manual.
Where do I find my model number?
Usually on a label under the robot or in the app.
Do all brands use the same codes?
No. Use your own model's list.
