roomba i3 error 99

Wondering why Roomba i3 error 99 appears out of a sudden? We’re here to help you!

The Roomba robot vacuum is one of the most commonly used robot vacuum cleaners.

It cleans your home surface as well as all the dirt, hair, and other tiny materials that accumulate on your home surfaces.

However, some of the errors such as “99” prevent the cleaner’s work!

The Roomba appears to be having trouble predicting the space to be cleaned, then it displays the error 99. In most cases, the problem is related to the map or the navigation of the robot and requires human attention to resolve the problem. 

Let’s move toward discussing what actually causes “Error 99” in the first palace!

What Causes The Error 99 Roomba i3?

what causes the error

Whenever Roomba is unable to clean the place, or when the vacuum is not capable of predicting the location, then Roomba will automatically stop cleaning and show the navigation or mapping errors “99”. 

It displays the mission report as “cancel”, “cncl”, and “incomplete”.

Here are some frequently reported causes of this error:

1. Dirty Sensors

Cleaning, mapping, and navigating with Roomba are all supported by many sensors.

But due to smudges, sensors become dirty and not capable of mapping the place, therefore the robot stops cleaning and displays a navigation error on the screen.

2. Obsticles/Obstructions

Due to a lot of clutters, and obstacles in the place where Roomba is cleaning, the cleaner can get dispositioned from the scheduled map.

That sometimes causes the cleaning failure.

3. Change in Location 

If the Roomba is running and you move it from current place to another, the robot can often get confused to understand where it is last time and how much the area is cleaned.

That’s why Roomba stops cleaning and sometimes shows “Error 99” until further notice!

4. Dock Station

When there is any obstacle between the Roomba and the dock station, the cleaner will be unable to locate the dock station.

That’s why the Roomba stops working and displays this error.

Solution #1 Clean The Navigation Sensors!

Roomba is a robotic vacuum cleaner and works on the basis of sensors.

It has 6 total navigation sensor that helps it to scan and move from one place to another for cleaning.

But when these sensors become dirty due to dust and hair, the robot’s operation will be disrupted.

Follow the below steps to clean the navigation sensors:

  1. Turn OFF the Roomba.
  2. Separate the Bin from the Roomba Robot. 
  3. Then you can see the 6 x sensors on the bottom. 
  4. Clean the Front, Side, and Back Sensors using cotton or fiber cloth. 
  5. Place the bin back into its position.
  6. Turn On the robot.

With the sensors cleaned, resume the cleaning schedule and observe whether “Error 99” will appear again.

In case the issue is persistent, next we’ll attempt something more advanced.

Solution #2 Power Cycle Your Roomba

Here we came up with another solution, which is to Power Cycle your Roomba device!

Whenever anything is not working or shows errors, the best option is the power circulation which essentially refreshes the entire operating system as well as all services.

This might help!

Here is how to power cycle your Roomba Robot:

  1. Turn OFF the Roomba Cleaner.
  2. Disconnect the Base Station from the power.
  3. Wait for 60 seconds!
  4. Turn on both the Base Station and Roomba Robot.

After the power circulation, resume the cleaning schedule of your Roomba and check whether error 99 will appear again.

In case it does, then let’s proceed further into the guide!

Note: Keeping the setup disconnected for longer, discharges both devices completely!

Solution #3 Clear Obstructions!

Another reason for the Error 99 Roomba i3 is obstructions. One of the mistakes that users do is to place the Roomba in a cluttered place.

Whenever Roomba detects any obstacle, it tries to go around and when there is another obstruction, the robot sometimes can’t continue. 

Clear the space between the Roomba Robot and Base Station!

This will allow Roomba to reach back into the base station and dispose of a full bin, which is another potential reason why the cleaning schedule stops.

In addition, remove any larger obstacles from the room where Roomba is cleaning. This will help with the navigation!

Tip: Test Roomba on another smart map, thus in another room.
