SHARK·FAULT ERR 16 WARN
Shark Error 16 — Robot stuck
Severity: Warning — robot is wedged in place and waits for a rescue IQEZAIAI UltraMatrixPowerDetect
DIRECT ANSWER
Error 16 means the robot is stuck. It is wedged under furniture, trapped by clutter, or its bumper is held pressed. Move it to a new location and make sure the front bumper moves freely.

COMMON CAUSES · RANKED
1
Wedged under low furniture MOST COMMON
Sofas and beds barely taller than the robot let it slide in, then pin the bumper or chassis on the way out.
2
Trapped by cables or clutter
Loose cords and floor clutter wrap the wheels or box the robot in mid-clean.
3
Bumper held pressed
The official fix pairs "move the robot" with "check the bumper moves freely" — a jammed bumper reads as permanently stuck.
HOW TO FIX IT
No battery or electrical work involved in this fix.
Rescue the robot
Lift it out of the tight spot and set it down on open, level floor.
Check the bumper
Press the front bumper in and release — it must spring back instantly on both sides.
Restart and fence off the spot
Start the clean again. If the robot keeps trapping itself in the same place, add a no-go zone or BotBoundary strip there.
