ECOVACS Deebot N79 does a pretty good job when it comes to daily cleaning on floors with solid wood or low pile carpeting surface.
Also, this robotic vacuum is a popular pick because of its reasonable price.
The battery charge works efficiently and is capable of cleaning a large space without causing any trouble if you use in the right way.
However, just like the N79S robot vacuum, Deebot N79 does have flaws as time passes, such as spinning in circles, not charging, and losing wifi connection. That’s why it’s important to search for Deebot N79 troubleshooting once realizing the malfunction of your machine.
Keep track of following tips and maintaining the robotic vacuum cleaner is much easier.
FAQs about ECOVACS Deebot N79

I’m going to discuss issues that frequently occur to your cleaning machine and hope the article about troubleshooting will somewhat help you.
I. How do I reset my Deebot N79?
You find out the scheduling function of your cleaning robot is cancelled all of sudden; however, this problem can be solved with ease.
The solution is to reset Deebot, and the process is simpler than you expect.
Firstly, press and then hold the Start/Pause button for 3 seconds. You’re asked to set the current time – if you hear the beep sound about 3 times and see the indicator light turning blow, then it means you succeeded with the scheduling.
On the other hand, you can tell the scheduling is cancelled if the indicator light goes green after 3 constant beeps. In this case, maybe you want to remove the current motherboard of Deebot N79 and replace with a new one.
II. How do I reset my Deebot battery?
When the device battery is low, you should instantly keep it powered on and connected to the charging dock. According to the manufacturer, this solution makes sure your robotic vacuum will have a full battery for the next cleaning time.
In addition, one of possible reasons for your Deebot N79 not charging is because the battery is discharged completely.
For this trouble to be resolved, you need to replace and re-activate the battery. Put the machine on the charging base manually by hand; after 3-minute charging, remember to disconnect it – you should repeat this process for 3 times.
Now it’s okay to charge normally!
III. Why is my Deebot not working?
Reasons causing your vacuum device to be obstructed (entangled) or have stopped working are actually a lot.
#1: Obstruction and entanglement
The most common reason stopping ECOVACS Deebot M80 and Deebot N79 from working properly is because it has encountered obstacles while moving.
Once this happens, quickly turn off the device. Our tips here are to lift your robot gently use your hand to remove any kind of dirt stuck so that it can function correctly later. Nevertheless, if you find your cleaning vacuum still has problems with the operating, then have a look at the dustbin and filter.
For a careful maintenance, it’s better to also clean the Deebot’s vacuum motor and its side brushes.
#2: Clogged dustbin or air filter
As I just said, you should check the device’s dustbin and air filter to see whether or not there’s debris remaining.
See also Deebot N79 manual for cleaner setup!
Again, shut down your cleaning vacuum and use a dry paper towel to clean the suction intake and brushes. Next, open the top of Deebot N79 and get the dustbin removed gently. If the dustbin is filled with debris, you just need to empty it. Besides, take out the attached air filter for a check – pat it moderately to get rid of dust.
Once you finish cleaning the filter, replace it in the dustbin. Use a moist towel to wipe down the dustbin and make sure it has to be dry completely before being slid back into the device.
#3: The power is OFF
If you find the Deebot N79 model not working, it’s probably because its power is off.
Always check to ensure the cleaning robot’s bottom power switch is turned on. We advise you to keep it powered on 24/7 and also on the charging station so that it will be available for usage anytime.
Manually replace the machine on the charging dock if it still does not function correctly.
IV. How do I get my Deebot back online?
This is a very common question when your Deebot goes offline.
The best answer for this circumstance is that the app function is temporarily unreachable. In order to connect the device online, please keep track of following instructions:
- Reset the machine to wake up your robot.
- Quit the ECOVACS app on your cell phone and then open it again for a new try instead of giving the phone a reboot. For Android users, double click the Home button and close your app from the task list. For iOS users, simply swipe over the app to exit.
- Visit the Google Play or AppStore to see if any new update is available yet. It’s necessary to keep your ECOVACS app updated frequently.
- Check the wifi indicator light on your Deebot N79:
- If the light is blinking, the possibility is your installed password to the wifi connection may be changed.
- If the light is solid, then possibly your wireless mobile carrier is dealing with the bandwidth traffic.
- Press the Reset button for 6 seconds and reconnect the robotic vacuum with the app if this issue still persists.
- Don’t mind making a contact to the customer support of ECOVACS in case you’re unable to get the Deebot back online.
Things to note:
The N79 robot only supports the 2.4G wifi, not 5G wifi or any enterprise network. In case your router sets both 2.4G and 5G wifi connections at the same time, then dispose two frequencies for particularly different SSID.
V. Why my Deebot moves in circles?
Your cleaning robot is supposed to go around the house for cleaning, not moving in circles. If this circumstance occurs, you need to gain a glance at Anti-Drop sensors (the device’s bottom) and make sure it’s not covered with dust. Sometimes the driving wheels tangled with debris can also prevent the robot from detecting objects appropriate.
Find the multi-function cleaning tool included in the ECOVACS Deebot package and use it to wipe away dirt on the sensors.
In Conclusion
Don’t be surprised if seeing your Deebot displays a bumper exception error; indeed, this circumstance usually happens to different models of ECOVACS vacuum. When the front bumper gets stuck in, the device tends to move back as it believes the obstacle is near.
For the robotic vacuum cleaner to return to its usual, you just need to take the front bumper out mildly about a quarter-inch.
With the Deebot N79 troubleshooting, most of your issues with the N79 will be solved easily. Schedule the device and it will guarantee to keep your house surface clean and fresh all of the time.
Cleaning is no longer a stressful matter!
You’re recommended to give your vacuum robot the maintenance once a month to lengthen its lifespan. Remember to empty the dustbin after every time cleaning to avoid any possible issue. If the house gets cleaner and has no animal fur, then you can empty it once per week.

Why does only one side brush work? I have cleaned my Deebot and replaced the filters and brushes. Could it be a bad module? If so how difficult is it to replace?
Deebot N79 beeps 4 times about a minute after getting on charger. It then repeats 4 more times for a total of 20 beeps. Also the red light is on instead of the blue light.
I read that it’s the battery, so I changed it. Also read it could be debris on shaft of main brush motor, so I cleaned it.
Don’t know what else to check, but it still does the same thing.
Hi Mike,
So, the beeping must be related to excess dirt and debris:
1. Read the diags label on bottom
2. make sure that the front single wheel is clean and free of debris
Sincere
DEBOT N79S gets battery failure 4 beeps with red auto light I replaced the battery and same problem. I runs for 2-3 minutes and stops, I push the auto switch on the remote and it will run again for 2-3 minutes and same thing happens.
Hi Ed,
I had a guess that it was due to hair/fur accumulation in the beater brush and after giving it a thorough cleaning. All it takes is removal of four tiny phillips screws and a flathead screw driver to help with removing the front wheel. You don’t actually have to unscrew the clean that piece, it’s not critical.
Sincere
My Deebot N79S appears to be charging while seated on the charging dock and/or plugged in directly from wall. The blue auto light is glowing off and on. However, when i push the auto button, the Deebot backs up with the auto button glowing red on and off, then returns to docking station.
I have replaced the battery and reset per instructions (3 mins on dock-3 mins undocked x 3 to no avail. Troubleshooting instructions are useless. Please help!
Hi,
Your detection sensor seems faulty; you can wipe the sensor, or you can start vacuuming from an enlighted surface.
Thanks!
Mine makes a clackety sound when it cleans. I think I this one of the roaring brushes. Is there any instructions to trouble shoot? Still cleans just noisy as the dickens.
Hi Sara,
Be sure your brushes on the bottom are all securely installed and the dust pan has not collected a small objects that maybe dragging across your floors. If all checks out then call customer service for assistance. Best wishes!
My Deebot won’t always return to docking station – why?
Hi Dan, If you wish to send your DEEBOT back to the charging dock early, you can use your remote or the app to do it. First, press the Play/Pause button on the remote, then you can press the charge/home button. You will notice the DEEBOT will stop vacuuming and will head back to the charging dock.
While your Deebot may take several minutes to find its charging station, it will eventually find it. It helps to keep your charging station in a clutter free area, with at least 2 feet of clear space on either side of the station.
While you probably don’t want the charging station right in the middle of the living room, it does help to test various locations for the charger. The charging station sends out a low power radio signal that attracts the Deebot. Sometimes, just the slightest location move of the charger can really help your Deebot find its way home.
Sincere
How can you replace a anti drop sensor?
My deebot seems to be having issues finding the charging port as of lately. We never had this issue before.
Hi Julie,
First, press the Play/Pause button on the remote, then you can press the charge/home button. You will notice the DEEBOT will stop vacuuming and will head back to the charging dock. While your Deebot may take several minutes to find its charging station, it will eventually find it.
Sincere
I have cleaned everything on my Deebot N79 and put it back on its charger. I beeps 4 times at intervals and does not charge fully. The blue light blinks continuously. All filters, sensors, contacts and brushes have been cleaned so I don’t know what else to do.
Hi Geri,
1. Read the diags label on bottom.
2 make sure that the front single wheel is clean and free of debris. I believe it also pops out but I have not done.
3. take out the main brush and make sure no hair/fur/string is making it brush slowly or clogging it. Make sure receptacle is clean.
4. Turn the Eufy off for about 30sec and then on again.
5. Make sure it’s charged.
I found it does weird stuff if it’s not fully charged and gets stuffed up. I have also removed the 4 small screws around the bases of each of the 2 main wheels and popped those out a bit and pulled a ton of fluff/fur out from around the wheel motors and in those areas. easy to do. I have come to realize that the Eufy will error when it is not rolling freely so all the wheels must be free of debris.
DEEBOT is powered ON when the AUTO Mode Button glows a continuous BLUE. * AUTO Mode Button blinks when DEEBOT is charging.
Thanks
Do not buy this product. After one year there is no suction. I replaced brushes and filters but still no suction. I cannot find anything blocking.
The side brushes will not stay on. The square hole in the brush slides in the square peg, but nothing holds it on. As soon as the Deebot is turned over the brush’s fall off.
HELP
Hi Babara,
Dismount the brush from the adapter (that’s what the screw does, because the adapter normally stays with the main robot assembly), and try to push the adapter onto the shaft as hard as you can. Once started, slip the brush onto the adapter, but leave the screw out; that will give a softer pad to hand push. Note: Tapping on the adapter is not recommended without going inside the ‘bot so you can buck up the other end of the shaft.
If you can’t get it to stay put, it it time to exchange that for a new one, one that is not subject to the limits of manufacturing tolerances like your present unit.
Thanks
My Deebot ecovacs won’t connect with the controller , when I turn it on it takes off runs over everything , when it hits something it just stops or runs over it , it’s not cleaning ..
Hi Barb,
You can check out this video to know how to solve this problem.
Thanks
We did everything suggested to keep the Deebot from going in circles, but it still does. Any other suggestions?
Or you can try this way:
Clean these with electronics cleaner, clean the deebot with electronics cleaner on the surface that is right behind where the bumper sits (there are sensors here too) and put it all back together. This fixed the spinning issue for me (mostly) and should fix it for most others.
Should the small wheel inside the large castor move freely? It seems like there is very much resistance…would that cause the deebot to go in circles?
Hi Bev,
If the DEEBOT goes backwards in circles, then check if the Main Brush is stuck.
Thanks
Why is my deebot keeps shutting off. I Replace the battery,has new brushes, Checked bumper,and it still turns off and the red light comes up.
Hi Ada,
If the device does not show signs of power, check the bottom of the Deebot. Locate the power switch and set to the the ON position. If the power switch is already in the ON position change the switch to the OFF position and manually dock it to the charging station. After three hours attempt to turn on again.
Sincere
I have had my Deebot about a year and used occasionally as it’s only for the room I rent. But it has now quit recharging. I manually press the Auto button. It begins to operate as if recharging with the button light pulsing and the small charge light goes on and off. About 30-40 seconds it shuts down. I have unplugged and re plugged the base unit to recycle, I have taken the unit off and back on several times. I get the beep tone and 30-40 seconds it shuts off. I have wiped clean the contacts but to no avail. What’s up?
Hi,
On the brush assembly there are two black knobs at each end. Remove the one without the screw (won’t hurt to remove both though). You can further take apart it with a pair of pliers. After you have done so you’ll probably find a big ball of hair — this is the reason why it’s getting stuck. Remove it, and your RoboVac is good as new.
Thanks
I’ve lost the remote and need to setup the Deebot N79 to a new wifi network. Can I set it up without the remote?
Hi Tyler,
I think you have to buy a remote, in the meantime you can push the button on the top to get it to start cleaning. After plugging it in directly and letting it fully charge a couple taps of the button made it automatically start cleaning. Also just an idea, if you still remember the name or password to your last WiFi, set up a hotspot on your phone with that information and after it connects see if you can change the settings to the new WiFi.
Thanks
I have a D79 Deebot and the machine is charging on the docking station but will not work ,the remote control has had the batteries changed but is not working with the machine ,I have cleaned it out and checked all the moving parts and they are moving OK. Remote doesn’t have a light on when I push the buttons. I have no lights on the machine itself to change the time or program .
Hi,
Ensure the robot’s side Bottom Power Switch is turned ON when Plugged in the Charging Dock. Your DEEBOT N79 Keep on the Charging Dock to make sure it has a full battery charge to work at any time as needed.
Thanks
I have a DN622.11, i had to replace my wifi router and logback into my Ecovac account which now doesn’t showvthe device and i cant get it back online. i tried the N79 settings since its the closest to it and it doesn’t work. Please advise.
Hi Robert,
Please ensure that the following steps are taken to connect your DEEBOT online:
– Pull down the product list to refresh – and that will wake your robot up.
– Completely close the App on your smart phone and open it to retry. For Apple smart phones, double click the HOME button and swipe over the App to close it. For Android smart phones, close the App from task list. Rather than just reboot your smart phones.
– Open the Google Play or App Store to see if there are any updates. Make sure the ECOVACS App/ECOVACS Home App is updated.
– Check the status of the Wi-Fi indicator light (next to the AUTO button).
✔If the Wi-Fi indicator light is blinking, check and see if the password to the 2.4G Wi-Fi connection has changed.
✔If the Wi-Fi indicator light is solid, check and see if your wireless mobile carrier/telecom operator is experiencing a bandwidth issue or cellphone traffic.
– If problem persist, please press reset button of the robot for more than 6 seconds and try to re-connect.
●If you are still having trouble getting your DEEBOT online, please contact ECOVACS Customer Care.
Thanks
