Hello. I had same problem. I cleaned casters but still got extractor error. Problem was one of the casters would not spin as well as the other. When sitting in the unit , you should be able to hand turn them. What I did was take off the yellow cap and then use pliers to hold the metal part and manually turned the caster to loosen it up and get it to spin again . Some hair was knotted holding it back and this helped me clean out / clear out the rest of the debris. Once I got it spinning again, worked find. Hope this helps.

Sorry to read about your problem, I hope this helps you out.

iRobot Roomba Vacuuming Robots and the iRobot Dirt Dog Workshop Robot are equipped with four infrared Cliff Sensors that prevent robots from falling off stairs or ledges. The Cliff Sensors are located along the inside of the bumper. If the Sensors become obstructed by dust or debris, the infrared signal is weakened. Regularly inspect and clean the Sensors. Use compressed air for best cleaning results.

Based on my measurements with a caliper, the inner diameter (ID) is about 3.5mm and the outer diameter (OD) is about 4.5mm. Length of tube is just shy of 60mm. Hope that helps! IF you find any sources for this tubing, please post more information.

I'm far from a Roomba expert and only clicked on your question out of curiosity given my background and as there was a similar question earlier Id passed.

A little research... Roomba NiMh battery pack is 14.4 v full charge. NiMh charging is a bit complicated, suffice to say it will eventually go well over 16V.

I would expect the charging station to have an initial charge voltage in excess of 12.5V. What I don't know is if its always on or waits to see if a load (roomba) attaches and then turns on its output.

So if you measured the power, contacts on the charger with a voltmeter and you get better than 12V likely its good, but really need to know what the voltage is when Roomba (with nominal battery pack) is docked.

Its likely the battery pack in the Roomba has a bad cell and will need replaced. You could measure the battery voltage but likely its low from not taking a charge. If its 14+ then the charger is working and the Roomba is misreporting.

Selecting the Wi-Fi connected Roomba robot language.
Roomba comes with a default language pack for the robot's spoken messages. Each language pack vary by region.
  1. Open the iRobot HOME App and select More ? Settings ? Robot Language.
  2. Choose either from your robots Installed Languages or select from the Additional Languages.
  3. On Roomba 900 Series and i Series you can choose either from your robots Installed Languages or select from the Additional Languages.
The factory default will return the robot's languages to the default pack that came with the robot.
Languages can only be changed when on your local Wi-Fi Network.

As with all vacuum cleaners, the unit can get dirty inside. There is a sensor under the brush unit that hears dirt hit it and triggers the circular cleaning action. This sensor looks like a dime sized hole with a bronze piece inside. Also the unit can be disassembled by removing 4 screws on the bottom and removing the top.
