Roomba 780 Robotic Vacuum\015 The ir sensor has broken off our roomba. I can solder it back on but which wires go to each of the three pins? there is a red, white and black wire.\015

How to Identify and Fix Common Vacuum Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :

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.
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.

Sensor light stays red no matter how long I vacuum. I think the sensor light is broken.
ANSWER : I think you have a clog and/or a dirty filter.
.Check all hoses – dont just look at them … disconnect them – run something through them – check completely. I pick up dozens of discarded machines from the trash heap – more than 90% have clogged hoses and nothing else wrong with them.
.I hope this helps

Hoover – Red Light Dirt Sensor
ANSWER : Check to make sure the settings didn’t get inadvertently switched to the hi position, move the switch back and forth from high to reg a few times, then leave it on reg.

remove and hand wash the primary filter and secondary filter, dry throughly and replace them in the vacuum.

if none of this works, you will need to have the vacuum serviced, or if it is still working, just don’t pay attention to the dirt-finder. the dirt sensor on your vacuum is located in the suction tube and is generally not accessible enough to clean without taking the vacuum apart.

hope this helps,

Brushes stopped The brushes stopped turning while using the cleaner. I removed the brushes to see if the spindle was broken, it wasn’t. I then removed the top plastic cover and checked the switch that engages the brushes; it didn’t seem to be moving correctly. There’s one spring on the switch – should there be two? Or do you think something has broken on the inside? Thanks for any help
ANSWER : Most likely the turbine is bad, it may just be clogged up, you can take it apart and clean it out real good. That may work, but it may not. Sometimes it is best to replace the turbine.

Is this free? i have a bissell carpet cleaner and i cannot get the soap and water to come out. it will **** up the dirty water however. i just found the belt is broken but i can see no way of how to put a new one in. is a broken belt the reason no soap is coming out?
ANSWER : If it is the flat belt that broke, that is the pump belt, the pump can’t work without it. To replace the belts, turn the unit over, remove the red holder, has one screw, pull it out, then the brush roll will come loose. You can replace the belts thru that opening.

Broken piece The black plastic octagonal end of the brushroll has broken off the brushroll, so the brushroll won’t stay in place. Can I get another little piece to attach onto the brushroll? Or do I have to get an entire new brushroll? And if so, do they sell replacement brushrolls? CP
ANSWER : You will have to replace the brush roll, part #60844-5, belt # 61120B. You should be able to get them from a repair shop, get the right one or it won’t work right. You maybe able to go and order direct.

Sensor dirt sensor light seems to be stuck in red
ANSWER : There is an optical sensor inside the port where you attach your vacuum bag. Take the bag off and take a clean soft cloth and wipe inside the port to remove dirt from the sensor. Don’t wet it! Do this every time you change your bag and you shouldn’t have a problem.
