How to Fix / Troubleshooting
Safety: Turn off the robot and remove the dust bin.
- Clean or replace filter: Remove the HEPA filter. If heavily soiled or older than recommended, replace it with a new Laresar filter.
- Check seals: Inspect the rubber gasket around the dust bin outlet. Ensure it is intact and seated properly.
- Clean airflow path: Remove any dust buildup in the bin cavity and suction inlet using a soft brush or vacuum.
- Reinstall and test: Fit the filter and bin securely, then start a cleaning cycle.
- If E18 persists: The internal airflow sensor (if equipped) may be faulty and require replacement.
