How to Identify and Fix Common Vacuum Problems ?

A Roomba contains both infrared sensors and photocell sensors, which work in combination to clean a room. The infrared sensor at the very front of the Roomba allows the vacuum to bounce light off an object to detect its presence, even if it`s cleaning after dark and there`s limited natural light.
While Roomba is cleaning, it avoids steps (or any other kind of drop-off) using four infrared sensors on the front underside of the unit.
All vacuum robots have cliff sensors as a safety requirement. Cliff sensors use infrared light, which is reflected from objects. The objects then send a signal back to the receiver in the vac. If the vac does not receive any signal, the receiver detects no object and changes the path.
There are two types of light sensors used in robot parts- photoresistors and photovoltaic cells. There are some more – CCDs, Phototubes, Phototransistors. However, these are very rarely used. Photoresistors change their resistance by changing light intensities.
The standard sensors are located on the robot vacuum`s bottom and bumper.
The two main light sensors used in robots are Photovoltaic cells and Photo resistor. Other kind of light sensors like phototransistors, phototubes are rarely used. The type of light sensors used in robotics are: Video Player is loading.
If the red Full Bin Indicator is illuminated or is blinking, it means Roomba senses that the Bin is full. Please clean the Full Bin Sensors. If Roomba continues to indicate the Bin is full after you have emptied the Bin, it means you have not thoroughly cleaned the Full Bin Sensors.
Factory reset on a Wi-Fi Connected Roomba® and Braava jet®
e Series Robots: Press and Hold the Home and Spot Clean and CLEAN button down for 20 seconds then release. 900 Series Robots: Press and Hold the Dock and Spot Clean and CLEAN button down until all LEDs illuminate.
The native code for Roomba is written in a dialect of Lisp.
You are able to have unlimited Android or iOS mobile devices connected to a single Wi-Fi enabled robot. Through your account on the iRobot® HOME app you can have up to 10 robots connected. If trying to connect more than 10 you would need to use another account and mobile device.
To test the Room Confinement sensor (a.k.a. RCON), place the Roomba within about six feet of the dock, with the sensor facing forward. Press and hold the Clean button for three seconds to clear out any prior cleaning jobs. Press the Clean button again, then press Dock.
Remove the Bin from the Roomba and set it aside. Look inside the robot where the Dust Bin was, and locate 2 black rectangular sensors on either side of the robot.

You can easily check the status of the battery in the iRobot® HOME App. A battery icon will be displayed in the top-right corner, indicating the current status of the battery. The CLEAN screen will display “Ready to clean. Charging,” indicating that the battery is not yet fully charged.
Keep holding spot and clean buttons down while the robot gives five ascending beeps, and five descending beeps. Release spot/clean and you are in diagnostic mode. Press clean to advance to the next test.
