Faults & fixes
Error 1 — LiDAR turret jammed, blocked, or not spinning so the robot cannot map. Cleaning is DIY; a tower that still will not spin after freeing usually needs an LDS module service.
Error 5 — hair or debris wrapping the main brush, ends, or installation slots. Recurring Error 5 after a thorough clean often means a failed brush motor or gearbox.
Error 13 (charging error) or the robot sits on the dock but battery % does not rise. Official steps cover oxidised contacts, dock power, and cable seating before any battery swap.
Auto-empty does not start, or starts but leaves dust in the bin / makes unusual noise. Goes beyond app toggles into bag, brush cover, and air-path blockages from the official Ultra manuals.
Dock reports an error / red status — Qrevo-family manuals point to voltage, tank seating, and cleaning-tank / tray-filter installation.
Qrevo-style docks will not wash mop cloths unless mopping was used, the dock is on the map, tanks are seated, and the cleaning tank/filter is installed correctly.
Robot cannot locate or mount the dock. Official guidance: clearance, clean dock signal area and robot front sensor, avoid starting far from a moved dock.
Official “fan speed lowered” guidance: check a blocked strainer/filter and replace the filter if cleaning does not restore suction. Wet filters must dry thoroughly before reuse.
Error 18 — vacuum fan fault. Official manuals say reset the system after clearing filter/dustbin issues. Recurring Error 18 is not a DIY fan swap for most owners.
