Faults & fixes
ALERT: Laser Sensor Abnormal — mapping fails. Official steps are lens wipe + reboot; a free-spinning tower that keeps alarming usually needs LDS service.
Hair or debris wraps the main brush. Recurring alerts after a thorough clean often mean a brush-motor fault.
Side brush or bearing wrapped in hair — common cause of edge-clean failure and running alerts on Omni models.
DEEBOT will not charge on the OMNI Station. Official troubleshooting covers outlet, cord seating, robot power switch, manual dock, contact cleaning, and genuine mop pads before service.
DEEBOT cannot find the station, or finds it but cannot enter / slips out. Combines official return FAQs with slip/wet-tray guidance.
Station fails to empty the robot dustbin, or reports bag missing/full after a new bag. Official steps include cabin close, dock seating, power-cycle, and firmware.
Dirty water will not recycle from the sink, or the robot says the dirty-water tank is full when empty. AU T30 + US X5 Omni FAQs cover seals, suction nozzle, and sink sensors.
App/robot says mopping pad plates are not fully installed or entangled with debris — common Omni wash/dock failures.
Weak pickup or abnormal fan noise after confirming brushes are clear. Official Omni FAQs call out cleaning the dustbin and suction nozzle, and fully drying a washed filter before reuse.
