ROOMBA·FAULT ERR 74 WARN
Roomba Error 74 — Maximum area reached
Severity: Warning — job ends early — the robot hit its coverage limit, not a fault j
DIRECT ANSWER
Error 74 means the robot reached the maximum area it can cover in one job. Very large or open floor plans trip this limit. Split the home into zones, or run a second job from a relocated dock.

COMMON CAUSES · RANKED
1
Floor plan bigger than one mission allows MOST COMMON
The robot covered everything it could and stopped at its area ceiling.
2
Wandering inflating the covered area
Navigation trouble makes the robot recross ground, burning area budget on repeat passes.
HOW TO FIX IT
No battery or electrical work involved in this fix.
Clean in zones
Send the robot to rooms or zones in separate jobs instead of the whole floor at once.
Relocate dock for far areas
Move the robot and dock into the uncovered part of the home and run a new mission from there.
Check for navigation waste
Review the Clean Map report — repeated passes over the same ground point to a navigation issue, not size.
