How to Troubleshoot Cliff Sensor in Coredy Vacuum Cleaner?
Robotic vacuum cleaners are pretty similar to us humans. Coredy vacuum cleaners come with cliff sensors that use infrared and photocell technology to guide the vacuum cleaner in the right direction. Cliff sensors make the vacuum aware when it is near a cliff, such as stairs or a balcony.
The cliff sensors help avoid accidents while your Coredy vacuum is running. If these sensors are not installed, the cleaner will fall from stairs and harm itself, or it may cause you some injuries as well. However, these sensors can stop working from time to time due to dust and debris accumulation.
The good news is that you can troubleshoot a faulty cliff sensor yourself. This section of the article will discuss how you can clean cliff sensors on your Coredy vacuum cleaner.
Follow the steps below for cleaning the cliff sensors on your Coredy vacuum cleaner!
- Place your vacuum cleaner on a flat table and make sure that it is powered off.
- Empty the dust bin and clean the filter.
- Remove and clean the main brush.
- Remove the bumper by unscrewing all the screws on it.
- Check if the bumper is stuck by debris. If it is clean, place it back.
- Reinstall the cleaned main brush.
- The cliff sensors are located on the side of the machine near the bumper, as shown in the image below.
- Most models have three cliff sensors. Two are located on the sides, and one is located on the top corner of the vacuum cleaner. Wipe them with a clean microfiber cloth. Be gentle with them as rubbing too hard can damage the sensors.
- Check if the wheel is stuck by pushing the wheel repeatedly. Remove any stuck debris or dust on wheels and ensure that they move freely.
- The last step is to install the dustbin.
- Test your Coredy vacuum cleaner to ensure that it is now working smoothly.
What to do if the cliff sensors don’t work or my vacuum cleaner doesn’t have them?
Don’t worry if your vacuum cleaner doesn’t have cliff sensors. Coredy sells virtual wall barriers for its customers. It is a device placed in the area you want your cleaner to clean, and then the vacuum will work in the specified location and will not fall or get blocked.

- If the battery level of the robot is quite low or the robot fails to come back to its dock, you hear four beeps.
To solve the issue, charge the robot or remove the obstacles blocking the robot from coming back to its dock.
Yellow light is on. Can’t get it green for cleaning
A green light indicates that the vacuum is charging on the dock, whereas the yellow light indicates that the unit is not properly charged. These problems usually highlight that something is wrong with the battery. Please check the battery and replace it if needed.
My R 650 will just shut off while cleaning, no flashing light or beeps
I can turn it off and on still nothing like the battery is completely dead
I can charge it and it works for about 10 minutes and does the same thing.
What’s the problem?
The problem indicates a potential battery issue. You must check the battery first of all. If the battery is fine, the issue can be related to some sensor or electric component getting heated and forcing the vacuum to shut down.
My cordy just goes in a circle then turns off I have cleared everything and even took off the bumper and put back on and it still does work can you please help me.
My robot only goes to the right and than turns off and it does the same thing going back into the charging station
Exact same issue! Still can’t find the solution.
This problem is probably a factory defect.
A robot vacuum usually goes in a circle when it finds an impediment or a hurdle to pass and returns looking for a way out. If the wheels are working fine, this is nothing on your end, and you can’t do much about it.
However, there is one thing you can try. You can power cycle the device. You can do this by holding the power button for 20-30 seconds. It will hard reset the machine, and this might work for you.
This problem can also happen due to a software issue. You can contact customer support to get this problem sorted.
It stopped working after a year. Does it have a replacement battery available
There is no error message or visible blockage
Yes. Coredy replacement batteries are available on their website (https://shop.coredy.com/collections/batterys) and at Amazon.
Good morning, mine don’t run backwards, I don’t know what to do?
[Translated by Webmaster]
A robot vacuum always returns to the charging base or the point where it started after completing a cleaning cycle.
If your robot is not going backward, it can happen due to a couple of reasons. First, it can be due to low battery; second, the bumper may not be behaving as it should, and third, you might have picked the vacuum during the cleaning cycle and moved it to a different place.
A low battery needs recharging or confirming if the battery has not gone bad. Second, you can deal with the bumper problem by reinstalling the bumper and confirming whether it is freely bouncing back and forth. Please consult the user manual to check the details for reinstalling the bumper.
You can deal with the third problem by starting a spot cleaning cycle from the base to see whether the robot finds its way back home or wanders here and there. You can also check the base in a couple of different positions with different directions from the starting point.
My Coredy r750 that I got for Christmas just spins, blinks red and then beeps 4 or 5 times. How do I fix this?
If your vacuum is blinking red and beeps, the following can be the reasons behind it.
• Two beeps with blinking red indicate that the front bumper might have been stuck.
• Three beeps with blinking red means cliff sensors might have been covered.
• Four beeps mean that vacuum has failed to be back to the charging dock.
If your vacuum turns off after beeping, a dead battery might be the culprit here. It can also happen due to software issues. Get in touch with customer service to sort out the problem.
Like a week ago stopped going back to the charging base after almost a year of normal work.
I am bringing the vac to the base manually and it goes green and starts charging. Then while charging makes four beeps and flashing red from time to time with interval like 10-15 minutes.
As far as the vacuum not going back to the base is concerned, it can happen due to three reasons.
A low battery, but in your case, it seems like the battery has worn out after a year of flawless operation; replace the battery and check if the problem has been solved.
The second reason for the vacuum returning to the base is the bumper problem. You can check this by reinstalling the bumper and checking if it is freely bouncing back and forth.
The third reason behind the vacuum not returning to the base is that you may have picked it up during cleaning and moved to a new place. The vacuum cannot orient itself back to the charging base in this case.
Let’s discuss the second part of your problem.
Four beeps with blinking red light mean that the vacuum has not reached the charging dock. Since you manually return the vacuum to the charging station, it isn’t guessing that it is back to the base. This looks like a software issue.
The best way to deal with this issue is to contact customer service.
I have l9000.
“ device is tilted”. What should I do?
The vacuum tilt problem indicates something is wrong with the wheels, or something is stuck at the bottom.
• Turn your vacuum upside to check if something is stuck at the bottom; remove it.
• Push the wheels up and down several times and shake out any loose debris that may be trapped in the wheels.
• Briskly turn both wheels with your hand and check that they move freely. Each wheel must exhibit the same amount of resistance.
• Restart your vacuum and check. If the problem persists, open the back cover and deep clean the wheels.
When the rolling brush of the Coredy R750 gets stuck, you hear four beeps.
To solve this issue, you need to clean the brush and the brush guard.
Thanks for this advice! With your suggestion I’ve managed to repair my Coredy.
Despite cleaning the brush and the guard, the problem persisted. Coredy would run for about another minute then stop and emit a few sets of 4 beeps. It was possible just to press the top button to resume, but the stopping and beeping would happen again a minute or two later.
The repair involved fully unscrewing the robot (base, under roller, and front bumpers), unclipping a few cables, lifting the circuit board and removing the dust suction fan. This allowed access to remove the belt mechanism inside the brush motor gear housing. There is a bearing (6800RS) that supports and drives the roller brush that was filled with dust and not rotating easily. After removing the bearing, applying lots of WD40 and gently rotating it, the bearing eventually spun freely. After a fair amount of reassembly, Coredy works again happily.
We have an R3500 and have been through all of the trouble shooting options for all combinations of flashing lights. It is actually flashing 4 times however after complete it trouble shooting solutions status remains the same. Are there other options? Is it possible the battery is bad?
Yes. There is a possibility that the battery has gone bad. However, I would suggest you go for a deep cleaning before ordering a replacement battery.
Performing the following steps may help!
• Unscrew the robot, including base, roller, and front bumpers.
• Unclip all the cables and lift the circuit board. Make sure you record the procedure so you can reinstall everything at the right place.
• Remove the dust suction fan.
• Removing the dust suction fan will give you access to remove the belt mechanism inside the brush motor gear housing.
• You will find a bearing that supports and drives the roller brush. Check if this bearing has dust.
• Remove the bearing. Clean it and apply generous amounts of WD40 to ensure frictionless movement.
• Reassemble the parts and check if the vacuum is working fine.
We would like to know what else we can do to get our cordey back into operating function. It is about two years old and we have never had an issue with the unit. Please advise.
You will need to diagnose the problem first. Try replacing the battery first and check what’s wrong with the unit.
Message regarding “fan failure” not working. Any suggestions?
Fan error is usually indicated by S4 error. You can deal with this by removing any object stuck in the fan. Restart the machine and then try again.
If this doesn’t work, you will need to open the vacuum, access the fan, remove it and clean it. Don’t forget to spray lots of WD40 on the fan to remove friction.
My Cordy 900 stops and says fan failure. Can you help?
If your machine is displaying an S4 error, it indicates fan problems.
The basic fix is to check the fan and remove any stuck object. If the problem persists, open the vacuum, remove the fan, clean it and spray with generous amounts of WD40.
Reinstall it and check it. If the problem persists, contact customer support.
hi , my Coredy is operating as normal but the water in water tank is not wetting the cloth for mopping.
Ever since I installed an air I mesh network, the device works for a short while then loses the network connection. The network connection in this area is very strong, so I assume it’s jumping between 2.4 and 5 GHz and at 5, it cannot communicate. How do I lock the IP address to stay at 2.4, even though Orbi automatically manages all channels to optimize. I am not going to set the router to 2.4 for everything, as I need the speed everywhere else.
This never happened with earlier routers.
I replaced the filter, roller brush and side brushes, but my coredy 750 does not have the same suction power as it use to.
You have tried all the recommended steps to troubleshoot reduced suction power. Your unit may be old, and general wear & tear has reduced its suction power. You can contact Coredy if the unit is under warranty; otherwise, you’ll have to replace it.
Hello, my coredy r500 beeps 4 times when it is charging. Looks like it’s saying it cannot find the base. Any solution?
The best solution is to pick up the robot and place it on the charging station. Make sure you don’t reuse the vacuum until it is fully charged. Coredy fails to find the charging dock if it is out of range or there are too many obstacles.
My Coredy continually says ‘Please return to level ground and start again”. I do that but it just keeps spitting that message back to me. I have tried spinning the wheels on bottom and they seem to rotate fine but no luck. Any other ideas? Thanks
My coredy runs for a few minutes then says roller brush error. I have cleaned the brush and even replaced it but it seems like it’s still difficult to turn like the their is a motor issue. Is there a way to replace the roller brush motor?
My Coredy R750 Pro won’t load onto the charging dock and after pushing the the blue button she says “low battery turn off” I push the red battery and nothing happens – I have turned off all plugs and re-plugged.
Any suggestions.
The problem seems to be with the battery. Is your vacuum delivering optimum battery time? If yes, and it fails to dock the charging station, try resetting the device.
If nothing works, contact Coredy’s tech support.
My vaccumme will work for second and then stops and keep beeping and flashing red light. I have cleaned everything.
Blinking red light means different things on different Coredy models. A general explanation is given below for beeping and flashing red lights.
• Two beeps with a blinking red light mean the front bumper is stuck.
• Three beeps with a blinking red light mean that cliff sensors are covered.
• Four beeps mean that the vacuum has failed to reach the docking station.
If you have cleaned everything and the battery is all right, contacting Coredy’s customer service is better before trying more DIY fixes. You may end up damaging your vacuum instead of fixing it.
