Roomba Error 12 — Move to New Location (Stasis)

What Does This Error Mean?

Roomba Error 12 means the robot detected it is not making forward cleaning progress — it is stuck, repeatedly hitting the same obstacle, or trapped in a confined space. This is a navigation safeguard, not a hardware fault. Picking Roomba up, moving it to an open area, and pressing CLEAN restarts the session.

Affected Models

Roomba 600 Series
Roomba 700 Series

Common Causes

Roomba trapped in a tight space between furniture legs it cannot escape
Long rug fringe or carpet tassel caught under the robot preventing forward movement
Power cable or phone charger cable wrapped around the wheels or extractors
Roomba repeatedly hitting the same low obstacle it cannot detect or climb over
Started on a very dark or highly reflective floor surface that confuses the navigation sensors

How to Fix It

Pick Roomba up and inspect the underside for any cables, carpet fringe, or string wrapped around the wheels or brush extractor.

Even a single thin cable looped around a wheel is enough to completely stop forward movement and trigger Error 12.
Place Roomba in the centre of an open area of floor, away from furniture, rugs with fringes, and trailing cables.

If Roomba was near a rug with fringe or under low furniture when the error happened, these are the most likely culprits.
Press CLEAN to restart. Roomba will resume cleaning from the new starting point.

Error 12 does not end the session permanently — restarting from a clear area works normally.
Identify the area where Error 12 happened and remove or block the obstacle that caused it.

Use iRobot Virtual Wall barriers to keep Roomba out of problem areas like under low beds or near rug fringes. This prevents Error 12 from recurring in the same spot.
If Roomba repeatedly gets Error 12 even in open space, clean the cliff sensors on the underside with a dry cloth.

Dirty cliff sensors can cause Roomba to misread its position and stop unexpectedly on clean, flat floors — particularly on very dark or very shiny surfaces.

When to Call a Professional

Error 12 is not a hardware fault and does not need a technician. If Roomba gets Error 12 every single run in the same room despite removing obstacles, the cliff or navigation sensors may need cleaning or the robot may need a factory reset.

Frequently Asked Questions

Is Error 12 a serious problem with my Roomba?

No — Error 12 is a navigation safeguard that fires when Roomba detects it is not moving forward. It is not a sign of a hardware fault. It simply means the environment has something Roomba cannot handle at that moment. Moving it to an open area and restarting is all that is needed.

Roomba keeps getting Error 12 in the same corner — what should I do?

That area has a recurring obstacle: a rug fringe, a cable, a chair leg configuration Roomba keeps getting trapped in. Block the area with an iRobot Virtual Wall device (a small battery-powered barrier) or physically remove the obstacle. Virtual Walls are the easiest long-term fix.
