Model issues and repair guidance

Preserve the beep count or red-light sequence before moving the robot. Gyroscope, bumper, cliff, caster, side-brush, fan and main-brush states each have distinct documented checks, while docking adds main switch, contact cleanliness and clear approach space. For a dry mop pass, inspect the removable water tank, outlet settings, plate and pad after dry pickup is restored. Do not route this robot to hose, belt or mains-cord repairs.Record beep count or red-light pattern, then check the named gyro, bumper, cliffs, caster, brushes or fan. Separate docking contacts and base space from wheel faults. For dry mopping, inspect tank, flow setting, plate and pad; no hose or belt applies.
