eufy Error 2 beeps — Bumper or side brush stuck
DIRECT ANSWER
COMMON CAUSES · RANKED
Flashing red — debris trapped under the bumper MOST COMMON
The official fix is to tap, pull and shake the bumper vigorously so trapped debris drops out, then wipe its surface.
Solid red — hair around the side brush
The manual maps two beeps with solid red to a stuck side brush — hair winds between brush and body until the motor stalls.
Bumper misaligned after an impact UNCOMMON
eufy's article covers an asymmetric bumper — loosen the screws on each side and reseat it before considering a replacement.
Side brush worn or deformed UNCOMMON
Bent arms drag and stall; eufy's fix is to snap on a spare brush — a click confirms correct fitting.
HOW TO FIX IT
Read the LED first
Flashing red points at the bumper; solid red points at the side brush.
Flashing red — free the bumper
Tap and shake the bumper to dislodge debris underneath, wipe it with a dry cloth, and confirm it springs back on both sides.
Solid red — clean the side brush
Turn off RoboVac, pull the side brush off, remove wrapped hair, clean the connector, and snap the brush back until it clicks.
Swap in a spare brush if it repeats
Fit a spare side brush (or swap the two on twin-brush models); a persistent error then points at the brush motor — contact eufy support.

Side brushes — 11S, 15C, 25C & 30C RoboVacs
These RoboVacs run two three-arm side brushes that pull straight off their posts; eufy says a correctly fitted brush snaps on with an audible click — replace them when the arms bend or the two-beep error repeats.
