eufy’s Dynamic Navigation (G-series) quick-reference page maps voice alerts to short first checks. The table does not give exact model or SKU coverage for most rows, and it is not a complete alert inventory. Match the robot to its own manual before removing a brush or using a procedure.

Quick reference

Alert on eufy’s G-series page What the page says First check in that page
Error 1 Front bumper stuck Tap the bumper repeatedly to remove dust; if needed, move the robot and retry.
Error 2 Wheel may be stuck or trapped Clear nearby obstacles and wheel dust, then move the robot and retry.
Error 3 Side brush stuck Clean the side brush and retry.
Error 4 Rolling brush stuck Remove and clean the rolling brush, roller joint, cover, and suction inlet only as the exact model instructions allow.
Error 5 Robot trapped Clear nearby obstacles and retry.
Error 6 Robot trapped or suspended Move the robot near the alert location; the page says to clean the edge sensor if it still cannot start.
Error 7 Wheels suspended Move it to a flat surface near the alert location and retry.
Error 8 Low battery Charge the robot and retry.
Error 9 Magnetic strip or strong magnetic field detected This row is limited to G30 Edge/Verge models used with boundary strips.
Error 10 Path-tracking sensor needs cleaning Check the exact model manual for the supported sensor-cleaning method.
Error 21 Auto-Empty Station blocked by nearby obstacles The linked detailed page is labeled for L70/G/G+ series; do not apply it to every G-series robot.
Error 22 Robot was picked up Put it back near the starting place.
Error S1 Battery Error Check the adapter and dock power, wipe the charging pins with a dry cloth, and allow the robot to dock using its supported button or app. Contact eufy if it persists.
Error S2 Wheel Module Error Check for stuck wheels or trapped dust, then restart. Contact eufy if it persists.
Error S3 Side Brush Error Check for an obstruction, then restart. Contact eufy if it persists.
Error S4 Suction Fan Error Check for a fan obstruction and clean the dust collector and filter as the manual directs. Contact eufy if it persists.
Error S5 Rolling Brush Error Clean the rolling brush and accessible connection, cover, and suction inlet as the exact model instructions allow. Contact eufy if it persists.

Important model limits

The quick-reference page does not say which exact G-series models use most of these rows. Its Error 9 row names G30 Edge/Verge with boundary strips. Its Error 21 link names L70/G/G+ series. Check the full voice message, product label, and current eufy manual before following a model-specific step.

A separate eufy support page for L70/G-series products describes Error 6 as a suspended robot or a robot stuck on a ledge, with dusty or covered drop sensors as one possible contributor. It recommends powering off and wiping the accessible sensors with a dry cloth, then retesting near the original location. That is a separate support page; it does not make the quick-reference Error 6 wording a universal eufy diagnosis.

If an alert persists after the documented external check, stop and contact eufy. An alert does not establish that a battery, fan, wheel, or sensor needs replacement.
