Shark Error 9 — Dust cup error
DIRECT ANSWER
COMMON CAUSES · RANKED
Dust cup not fully clicked in MOST COMMON
After emptying, a half-seated dust cup looks installed but never presses the detection switch — the classic trigger.
Debris on the dust cup seat
Grit on the rails or seals stops the cup from seating deep enough to register.
Dust cup latch damaged RARE
A cracked latch can no longer hold the cup tight; the error returns every few minutes until the bin is replaced.
HOW TO FIX IT
Remove the dust cup
Press the release and pull the dust cup out of the robot.
Clean the seat
Wipe the opening and rails where the cup slides in so nothing blocks a full insertion.
Reinsert until it clicks
Push the dust cup back in until it clicks solidly into place, then restart the clean.
