iRobot Roomba i Series, j Series and s Series error 22 or error 24: meaning and exact next steps

error 22 or error 24 means Both point to the robot's environment. For error 22 the spoken message is "Move to a new area, then press Clean." For error 24 it is "Place on a flat surface, then press Clean." This answer applies only to Roomba i Series, j Series (including Combo 10 Max) and s Series robots whose light ring turns solid red and that speak an error message, as listed on iRobot's three error message charts. The three charts share one numbering, and a row says where a chart words an error differently. Older Roomba lines are on their own pages.

On the covered iRobot Roomba i Series, j Series and s Series, error 22 or error 24 means both point to the robot's environment. For error 22 the spoken message is "Move to a new area, then press Clean." For error 24 it is "Place on a flat surface, then press Clean." First, move the robot to a new area (error 22) or place it on a flat surface (error 24) and press CLEAN.

Model-specific

What is true of this model and not of its siblings

Two codes, one theme
iRobot's chart lists the robot's surroundings for error 22 and the wheels for error 24. The robot is telling you it cannot navigate where it was left, either because the spot confuses its sensors or because the wheels cannot get a grip.
Where it goes wrong
Thresholds, thick rugs, black carpet and glossy floors are the usual culprits. A robot left on a rug edge, or half on a stair, will report one of these.
A simple routine
Move the robot to an open, flat part of the room, press Clean and watch the first minute. If it behaves, the earlier spot was the issue, and a keep-out zone in the app can avoid it.
Using the app to prevent it
The iRobot Home app lets you draw keep-out zones around rugs, thresholds and stair edges, and to schedule cleans when the floor is clear. Once the robot has learned the map, repeated environment errors in the same spot are a good sign that a keep-out zone is needed there.
Cleaning sensors
The cliff sensors on the underside look at the floor to detect drops. Dust and pet hair on them make the robot think it is at an edge. Wipe them with a dry microfibre cloth weekly.
