The roomba is a disc-shaped robotic vacuum cleaner. As the Roomba series cleans, it communicates with beeps, songs, and indicator lights. It also uses sounds to let you know when there’s a problem or if it needs maintenance. A list of the most common error codes, what they mean, and how to resolve such problems follows: 1. A 4-Note tune while the power button blinks red indicates Roomba’s battery is low and needs recharging. Simply connect Roomba to a battery charger called a Home Base. 2. An “Ehh” sound means Roomba’s cliff sensors are malfunctioning or dirty. Simply turn over and check for debris underneath and around the cliff sensors which can be easily cleaned by Wiping the sensors with a lint-free cloth or by using a can of compressed air. 3. An “Uh-oh” means Roomba’s side wheel is not touching the floor or is stuck. Lift Roomba from the floor and reset the cleaning cycle after placing it in the center of the room. 4. An “Uh-oh” with 1 Beep indicates Roomba’s main brushes have stalled. Turn it over, remove the brush guard and the main brushes and inspect them for any obstruction. 5. An “Uh-oh” with 2 Beeps means the side brush has stalled. Turn Roomba over, inspect the side brush for dirt or obstructions, place Roomba in the center of the room and reset the clean cycle. 6. An “Uh-oh” with 3 Beeps means Roomba’s vacuum stalled. Remove and empty Roomba’s dirt bin. Using a flat-head screwdriver, remove the grill at the back of the dirt bin, then shake out any debris that may be stuck. Replace the grill and the dirt bin if problem continues. 7. An “Uh-oh” with 4 Beeps means Roomba’s side wheels have stalled. Simply lift up Roomba, placing it in the center of the room and restart Roomba’s. If Roomba does not resume cleaning, turn it over and inspect the side wheels for any obstructions. Check the side wheels to see if they are moving properly by pushing them in and out. Place Roomba in the center of the room and reset the clean cycle. 8. An Uh-oh” with 6 Beeps means Roomba’s wheel-drop sensors have overloaded. Raise Roomba from the floor placing it back in the center of the room and reset its clean cycle. 9. An “Uh-oh” with 9 Beeps means Roomba’s wheel-drop sensors have failed at its startup. For this you will have to contact iRobot® Customer service. 10. An “Uh-oh” Plus 10 Beeps means Roomba’s bumper is not recognizing obstacles. Check to insure that Roomba is not stuck in one place, but if so, move Roomba away from obstructions. Tap the bumper on all sides several times to loosen any possible debris that may be lodged in it. Then place Roomba in the center of the room and reset the clean cycle.
