These eufy support tables apply to three different products. Match the robot name and full alert before using a check. An S1 Pro E-code, an L70 Hybrid Error number, and an X9 Pro Error number are not interchangeable.
S1 Pro robot and base station
The S1 Pro guide has separate robot and base-station rows. Examples include:
| Alert | Listed first direction |
|---|---|
| E00 dustbin absent or not seated | Reseat the dustbin level with the robot surface, close the cover, and press Start. |
| E01 roller brush blocked | Remove and clean the roller brush, slot, and shaft ends; reinstall the brush guard until it clicks. |
| E31 wheel debris | Check wheel movement, clear the wheel gaps, and press Start. |
| E55 anti-drop sensor blocked | Remove debris and wipe the sensor with a soft cloth. Because the source warns that blockage can allow a fall, keep the robot away from stairs and thresholds until the alert is resolved. |
| E74 or E76 cannot find the base | Check whether the path is blocked; the guide lists moving the robot near the base and pressing Return to Base. |
| EB01 dust bag full | Replace the base dust bag as directed by the S1 Pro support page. |
Other S1 Pro base messages identify clean- or dirty-water tank, tray, and cleaning-solution states. Confirm whether the prompt begins with E or EB and which unit is speaking.
L70 Hybrid
The L70 Hybrid page includes numeric alerts and a separate S-code family. Examples from its table:
| Alert | Listed meaning or first check |
|---|---|
| Error 1 | Front bumper stuck; tap repeatedly to dislodge dust, then reposition if needed. |
| Error 6 | Robot may be suspended; move it near its original position and clean the edge sensor if it still will not start. |
| Error 14 | Dust collector or filter is not installed; reseat and restart. |
| Error 20 | The laser sensor may be blocked by an empty area, metal mirrors, or other multi-reflection devices; remove the interference or move to another area. |
| Error S1 | Check adapter/base power and charging contacts; dock the robot facing the base. |
| Error S2 | Check for a stuck wheel and clear dust before restarting. |
The source does not explain the missing Error 10 row or claim its lists are exhaustive. Do not assign a meaning to an unlisted number.
X9 Pro robot and auto-clean station
The X9 Pro guide separates robot and station alerts. Examples include:
| Alert | Listed first check |
|---|---|
| Error 2 | Clear material from the wheel gap and check that the wheel turns freely. |
| Error 14 | Reseat the dustbin and filter. |
| Error 18–20 | Check the laser cover or sensor for obstruction using the specific message. |
| Error 21 | Clear an obstruction at the station entry. |
| Error 27–29 | Check the cleaning tray, station tray installation, or lid according to the exact message. |
| Error 30 | The station input voltage is abnormal; check the unit’s voltage requirements against local supply. Do not infer a regional SKU from the voltage alert. |
These are selected rows from current support pages, not complete alert dictionaries. Use the link for the exact model and the exact spoken or app message for other alerts. If a prompt repeats after the listed external check, contact eufy support. The existing G-series voice alert table and X8 wheel alert guide have separate product scopes.
