SHARK·FAULT ERR 7 WARN
Shark Error 7 — Cliff sensor error
Severity: Warning — robot stops because it can't trust its drop sensors IQEZAIAI UltraMatrixPowerDetect
DIRECT ANSWER
Error 7 means a cliff sensor error — the robot thinks it isn't on a level surface, or the sensors need a reset to read correctly. Move it to open floor and wipe the cliff sensors under the bumper.

COMMON CAUSES · RANKED
1
Dusty cliff sensor windows MOST COMMON
A film of dust over the sensors under the front edge makes the floor read as a drop.
2
Robot not on a level surface
Half over a stair nose, threshold or ledge, the sensors correctly report a drop and stop the mission.
3
Sensors need a power-cycle
Shark's own guide says the robot may simply need a reset to get an accurate sensor reading.
HOW TO FIX IT
No battery or electrical work involved in this fix.
Power off the robot
Take it off the base and hold POWER for 3 seconds.
Wipe the cliff sensors
Turn the robot over, find the cliff sensors underneath near the bumper, and wipe off dust and residue with a clean, dry cloth.
Restart from the dock
Set the robot back on the base to power it on, then press VACUUM. If the error repeats, contact Shark support with your model and the code.
