Deebot N79 bumper exception 

Sometimes, the front bumper of your DEEBOT may get stuck in, which mostly happens in the Roomba vacuum. This occurs when the sensors of the bumper are grimy which known as Roomba Error 9. When that happens, your robot will only go abaft as it thinks the obstacle is closing in on it!  Just mildly take out of the front bumper a quarter-inch – and voila, your DEEBOT should be back to usual.

The amount of time Deboot N79 will save is ridiculous. We literally have to vacuum every day to keep the house feeling and looking clean and fresh with Ecovacs Deebot N79S, Because, we have a dog and a cat, and kids. Just Schedule it and forget about cleaning.

As your house gets cleaner you’ll be able to go without emptying it for a weak. Without a few problems in all, I’m happy with my Deboot N79.

      To cancel the scheduled cleaning time, press the bell button on the Remote Control and hold the button for 3 seconds until disappears from the Remote Control LED Screen and the robot beeps. Now The scheduled cleaning time is canceled.

      Thanks!

  3. when using my deebot N79S, it BATTERY discharges (BLINKING RED LIGHT) within 10 minutes and runs back to the dock where it charges with the blue light blinking for about 5 min and then the light turns off. its the same process again after its charging on the dock for over 12 hours. Can you help us to figure out how to fix this issue? Thanks!

    • You can try this video. In this video shows how to fix your main brush error. If you removed the brush, cleaned it, and are still getting the error, it’s most likely the motor inside that needs to be cleaned.

    • If the Main Brush still rotates slowly and showing same error, Remove the dirt and debris tangled around the Main Brush with the given Multi-Function Cleaning Tool. Or you can buy a new Main brush from Amazon.

    • Every time it would dock after vacuuming, it would wait about 1 minute then start beeping. It would beep 4 times, wait a few seconds, then beep another 4 times, repeating the process a total of 5 times. It would then wait 30 seconds and repeat it all over again – a total of 5 times. The whole time, the light on the top would flash red. After all the beeping, it would stay red. Isn’t it?
      The video shows the problem, the beeping, replacing the battery, and how it solved the problem.

  12. Hello,
    I’ve had my deebot for a year and a half. Ive had it replaced once and now it turns on for two minutes and gives me an error four beeps. I noticed that main brush isnt turning. I clean it and it does the same. I have replaced the battery and the main brush and still the same thing. I called the company and told them and they said it must be an internal issue and that my vacuum was out of warrantee and they were sorry but they dont have repair centers. I even took the thing apart and replaced the other mini battery that was inside and still it’s the same thing.

  13. I have tried all the procedures to connect my N79 to my wifi. i’ve done the manual process and I can see the ecovacs-xxxxx network but the Deebot won’t connect. I’ve put the deebot 4 ft from the router, my iphone on the deebot and i get fail notice.

    Reply
    • The number one problem is that you are running on a 5 GHz network. You need to connect to the 2.4 GHz bandwidth router in order to connect the Deebot to the wifi.

  18. Hi Jim,
    My Deebot N79 does a consistent set of 3 beeps x 5 sets. The docking charging light blinks blue between the sets and turns red when beeping. After 5 sets it stops. the unit also began to act confused, turning in circles before finding its way back to the docking station. this happened in the middle of the floor so there was nothing INTERFERING with its movement

    • Hi pat,
      Your detection sensor seems faulty; you can wipe the sensor, or you can start vacuuming from an enlighted surface.

      Thanks!

  19. Hello, my deebot will only run for a few feet before it stops and beeps …NOthing getting in the way or PHYSICALLY stopping it…. I’ve cleaned and wiped off the sensors not sure what to do or replace at this point ……any help

    Reply
    • Unfortunately, your Deebot N79 seems to no longer be able to detect objects. It always bumps into objects before changing direction and cannot finish a clean cycle without getting stuck multiple times. Am I right?

      I think, you will need to wipe the detecting sensor or change the sensor.

      Thanks!

  21. My two year old Deebot N79 suddenly died; no lights come on when in the docking station and it does not respond to the remote control. The green light on the docking station is on so I don’t think it is that. I may have a dead battery but want to be sure before buying a replacement. How can I verify it is the battery?

    • The manual had no information on what the error would be. The battery also seemed to be working satisfactorily. Even so, if it meant the beeping would go away, we figured we’d try replacing the battery.

      The video shows the problem, the beeping, replacing the battery, and how it solved the problem.

    • You can end up unscrewing the screws that hold the bumper onto the front of the robot. You can able to re-seat it properly and then re-attached, and it may work fine.

  23. I love my Deebot M81 Pro. I have had it since June 2019. It gets cleaned and looked after regularly, In the last week, it has been making a terrible racket . I don’t know what to do to correct this. Can you please help.

    Reply
  24. The motor that drives the brush is attached to small housing with a series of several plastic gears inside. The largest of those gears gets worn out the quickest.
    On mine, it would make a terrible rattle noise, which was actually the sound of the brush gear slipping. The vacuum itself gave no error codes and just kept going making that horrible loud noise almost constantly.
    I could not find anywhere to buy that small plastic gear. It is a very unique size with 29 teeth.
    I ended up using a 3d printer to make a brand new gear for it and now it works great.

  26. My deebot n79 series goes to the dock and then the auto light turns red and start a non stop beeping until it comes off. It also does the same thing when you plug it directly into the power supply on the sides. Any thought? I have already purchased a new battery.

  27. I replaced the battery in my Deebot N79 – followed directions for reactivating the battery. It sits on the charger and the blue light blinks rapidly verses the normal blinking it did with the original battery. I’ve tried several new batteries thinking the battery may have been bad to no avail. Suggestions?
