Shark Error 24 — Battery critically low
DIRECT ANSWER
COMMON CAUSES · RANKED
Robot drained away from the dock MOST COMMON
A robot stranded mid-clean or parked off the dock self-discharges until the pack hits the critical threshold.
Dock not actually charging
Dirty contacts or an unplugged dock leave the robot draining while it looks docked — the official fix says to confirm the indicator turns blue.
Battery reaching end of life UNCOMMON
An aged pack that dives from full to critical in minutes needs replacing with a genuine battery.
HOW TO FIX IT
Dock the robot
Place it on the base and confirm the charging indicator lights up blue.
Let it charge fully
Give the robot a full charge before the next mission — several hours from empty.
Check contacts if it never charges
No light means no current — clean the contact strips on dock and robot and check the outlet.
Replace a worn battery
If runtime keeps collapsing, fit a genuine Shark replacement battery rather than a no-name pack.
