The ILIFE V3s Pro manual’s error-code sheet uses short-tone counts for three trouble classes. Confirm the model label before using the table: it covers the V3s Pro only, not every ILIFE robot. Count the short tones in the alert and match one, two, or three to the manual’s rows below; it gives no meaning for a different count or timing pattern.
| Short tones | Manual’s listed condition | First check |
|---|---|---|
| 1 | Wheels or side brushes are not working | Check the wheels and side brushes. |
| 2 | Cliff or bumper sensor issue | Clean the cliff sensor and check the bumper for foreign matter. |
| 3 | Robot body is stuck | Move the robot to a clear area and start it again. |
The rows identify the manual’s trouble categories; they do not prove that a part has failed. Use only the first check shown for the matching row. If a wheel or side brush still will not move, the two-tone sensor alert persists after cleaning and inspection, or the robot cannot restart after you move it to a clear area, stop and consult the complete V3s Pro manual or contact ILIFE support before trying another procedure. Do not resume cleaning near stairs or ledges while the two-tone cliff-sensor alert remains. For an unlisted pattern or a model mismatch, record the full alert and use the alert identification workflow rather than guessing.
