Common Questions
Why do I keep getting E05 even with dustbin installed?
Dustbin sensor contacts are dirty. Remove dustbin, wipe gold contacts on both dustbin and robot with dry cloth. Ensure filter is completely dry. Push dustbin in until you hear/feel definite click.
Can I reset error codes without fixing the problem?
You can restart robot to temporarily clear code, but error will return if underlying problem not fixed. Always address root cause - resets are not fixes.
My M8 Pro shows no error code but won't work - why?
Check if power switch is ON (side of robot). Ensure battery charged. Try full reset: hold power button 15 seconds. If still dead, may be internal issue - contact support.
How do I factory reset my Proscenic M8 Pro?
Hold CLEAN + HOME buttons simultaneously for 10-15 seconds until all lights flash. This erases maps, schedules, Wi-Fi. Use only as last resort for persistent software issues.
Do error codes mean my robot is defective?
No! Error codes are normal troubleshooting tools. They help identify specific problems. Most are maintenance-related (hair tangles, dirty sensors) not defects. Regular cleaning prevents 90% of errors.
