COMMON CAUSES · RANKED

Robot stranded away from the base MOST COMMON

A robot trapped mid-clean or started far from the dock drains flat before it can return home.

Base not actually charging

Dirty charging pins or an unpowered base leave the robot draining while it looks docked — the base's white indicator should be lit.

Battery reaching end of life UNCOMMON

eufy rates its lithium packs at roughly 300-500 charge cycles; a battery that collapses from full to empty mid-clean is due for replacement.

HOW TO FIX IT

No battery or electrical work involved in this fix.

Return the robot to its base

Carry it to the charging base and seat it on the pins; confirm the charging indicator comes on.

Charge fully before the next clean

Give it a full charge. Starting missions from the dock also lets the robot budget power for the return trip.

Replace a worn battery

If runtime keeps collapsing after a full charge, fit eufy's official replacement battery for your series rather than a no-name pack.
