The N79W is rated slightly higher, at up to 120 minutes of run time. Check your own manual rather than assuming the numbers carry across variants.
Cleaning modes and what each one is for
Auto Mode
The default. The robot moves across the floor in its own pattern until the battery runs low, then docks. This is also the mode every scheduled cleaning runs in — you cannot schedule Spot or Edge.
Spot Mode
Cleans one concentrated area in a spiral. Place the robot directly over the mess, then start Spot. Useful for spilled cereal, litter tracked out of a box, pet food scatter.
Edge Mode
Follows the perimeter of the room along walls and into corners. Run this after Auto rather than instead of it — Edge does not cover the middle of the floor.
Single Room Mode
Cleans one room, then returns to where it started. The room has to be closed off. If the door is open, the robot wanders out and the mode does nothing useful. Close both the entrance and the exit before starting.
Indicator lights and alarm beeps
The AUTO button on top of the robot is the status light. This is the table worth screenshotting.
| AUTO button | What it means |
|---|---|
| Flashing blue | Charging |
| Solid blue | Cleaning |
| Solid red | Battery is low |
| Flashing red, or solid red with beeping | A fault has been detected — count the beeps |
When the robot detects a problem it beeps and the AUTO button turns red. The number of beeps identifies the fault:
| Beeps | Fault | What to do |
|---|---|---|
| 1 beep | Robot is stuck or suspended | Move it onto a flat, open surface, clear whatever it is caught on, restart |
| 2 beeps | Anti-collision bumper malfunction | Press the front bumper in and release it several times to free anything jammed behind it, then wipe the bumper edge clean |
| 3 beeps | Anti-Drop Sensors Malfunction | Clean Anti-Drop Sensors as described in section 4 Maintenance. |
| 4 beeps | Low Battery | Press the front bumper in and release it several times to free anything jammed behind it, then wipe the bumper edge clean |
How to reset the DEEBOT N79
The most common reason to reset an N79 is that the cleaning schedule has silently cancelled itself. The procedure is the same across N79, N79S, N79SE and N79W.
- Make sure the power switch on the underside of the robot is ON.
- Press and hold the START/PAUSE button for about 3 seconds.
- The robot prompts you to set the current time. Set it.
- Listen for three beeps and watch the indicator light.
Light turns blue — the reset worked and scheduling is active again.
Light turns green — the reset did not take and the schedule is still cancelled. Run the procedure again from the start.
Maintenance schedule
The N79 has no self-emptying base and no brush-tangle protection. It depends entirely on you cleaning it.
| Part | Clean | Replace |
|---|---|---|
| Dust bin | After every run | — |
| High-efficiency filter | Tap out weekly | Every few months, sooner with pets |
| Main brush | Weekly — cut hair away with the cleaning tool | When bristles are visibly bent or thinned |
| Side brushes | Weekly | When the arms stay permanently bent |
| Anti-drop sensors (underside) | Monthly — wipe with the dry cleaning tool | — |
| Charging contacts (robot and dock) | Monthly — dry cloth | — |
| Front wheel | Monthly — pull out and clear hair from the axle | — |
Dirty anti-drop sensors are the single most common cause of an N79 that refuses to move, or that reverses away from a perfectly normal patch of dark flooring. Wipe them before assuming anything is broken.
Replacement parts
ECOVACS discontinued the N79 line, so first-party stock is gone. Third-party filters, brushes and batteries are still widely available and are what most owners use.
- DEEBOT N79 filters — the cheapest part and the one that affects suction most
- Side brushes — usually sold in multipacks
- Main brush
- Replacement battery — the fix for a robot that docks constantly or dies mid-room
Check Amazon for current pricing and confirm the listing names your exact variant before ordering.
Frequently asked questions
Does the DEEBOT N79 work with Alexa or Google Assistant?
The base N79 does not. The N79S, N79SE and N79W do, through the ECOVACS app.
Can the DEEBOT N79 mop?
Some variants ship with an optional mop attachment. It is a damp-cloth drag, not a scrubbing system — fine for dust on sealed hard floors, not for dried spills.
Does it map my house?
No. The N79 predates mapping. It navigates by bumping and sensing, which is why it covers a room by wandering rather than in neat rows, and why it needs more time per room than a mapping robot.
What floors does it handle?
Hard floors and low-pile carpet. Deep-pile and shag carpet will stall it. Large open-plan spaces are also a poor fit — without mapping it cannot cover a big area efficiently on one charge.
My N79 beeps but the manual does not list my beep count
The beep table above covers the two most common faults. For the full list, open the official PDF for your exact variant using the download links above — the fault tables differ between the N79 and the N79S/SE/W manuals.

The clock is wrong on the remote. How do I ser it to the proper time?
push the clock icon button (middle of first row), up / down to change the number, left / right to move between hour / minute. scroll thru hour to get AM/PM.
Hi Curtis,
The remote has a separate setting that isn’t visible from the app. Hold the timer button for 3 seconds to disable the cleaning at midnight or to change it to a more convenient time.
Sincere!
I really like this machine, however it stopped in the middle of cleaning. I did the 3 second reset suggestion, but it will not power on, at the charging station it lights up blue, but the Auto power button is flashing. WiFi is connected, batter sensor says charged, however when I pull it off the charging station all light indicators go off. What else can I try?
I also have this problem. Were you able to find a solution?
Dear Maries,
Possible Cause: DEEBOT is tangled with something on the floor (electrical cords, drooping curtains, area rug fringe etc.). While the Deebot is pretty good at getting our jams – some common household items can trip it up.
Solution: DEEBOT will try various ways to get itself out of trouble. If it is unsuccessful, manually remove the obstacles and restart.
Sincere!
I’ve only had my deebot a little over a year and now it won’t charge. I replaced the battery but it still won’t work. Unfortunately my warranty is over and my receipt sadly found its way to the trash along with the box. Is there something I can do to troubleshoot it and get it back working?
Dear Tracey,
Possible Cause: The Bottom Power Switch on the bottom of DEEBOT 83 is not turned ON.
Solution: Turn the Bottom Power Switch to the ON position. The “|” is ON, the “O” is OFF
Possible Cause: DEEBOT 83 has not made a connection with the Charging Dock.
Solution: Be sure that the DEEBOT 83 has made a connection with the charging dock pins. You may move the robot manually to make the connection if necessary.
Possible Cause: Charging Dock is unplugged while robot’s Bottom Power Switch is ON, which causes battery consumption.
Solution: Plug in the Charging Dock and ensure the robot’s Bottom Power Switch is turned ON. Keep DEEBOT 83 on the Charging Dock to make sure it has a full battery to work at any time.
Possible Cause: The battery is completely discharged.
Solution: Re-activate the battery. Place DEEBOT 83 on the Charging Dock by hand, remove after charging for 3 minutes, repeat 3 times; then charge normally.
no puedo conectar la aplicación de mi dispositivo al Deebot, lo he intentado múltiples veces y siempre marca el estado fuera de linea o sin conexión, y mayormente se mantiene cargando para enviar algunos mandos y no ejecuta ninguna acción.
My debit comes on at 1:15 in the morning. Not sure how it set for that, I must have pushed some wrong buttons. How can I cancel that cleaning time?
Turn the deebot side switch off, then back on. that will clear all schedules
Thru the remote:
First set the time on the Deebot: press AUTO>press CLOCK> use up/down/right buttons to get current time>press the middle (play/pause) button to save ( >|| )
To set an automatic schedule: press BELL+CIRCLE (middle row, left button)>set time same as clock above>middle (play/pause) button to save ( >|| ). It will run every day at that time.
To pause schedule, hold the BELL+CIRCLE for 3 seconds until the icon on the screen turns off.
if you want to customize for certain days/multiple times, you’ll need the ecovacs phone/tablet app
My DEEBOT kept coming on and cleaning at midnight every night. I found that if you hold the Schedule button down for 3 seconds, it shuts off the programmed schedule. You would have to turn this back on if you want it to run the schedule again later.
My app it working. My deebot doesn’t have a barcode? How to scan? Please help

Hi Nancy,
To Delete A Schedule:
Press and hold SCHEDULE.
While holding SCHEDULE, press the DAY button to cycle through Roomba’s scheduled cleaning times.
When Roomba is displaying the scheduled cleaning time you’d like to delete, press and
hold DAY to delete the scheduled cleaning time.
Release SCHEDULE.

Instruction to cancel schedule cleaning time for Deebot N79W model:
First you have to press the alarm button, and change the time, preset time is 12:00 am, change it to any time you like, and set it by hit play button, you will hear one beep and alarm picture will appear on the Remote control LED screen. After you done the first step, then hold down the alarm button, you should hear the machine beeps 2 times and the alarm button disappear on the Remote LED screen. This should clear the cleaning schedule time.
My DB is beeping 4 times about every 15-20 minutes? Any ideas why this is happening?
Please update your online documentation. None of your instructions work with my model purchased in 2019. i.e. holding down the start button does not Reset the deebot, nor does holding down the autobutton reset the network.
Thank you, same for me!!!!
I am wondering if I can change my email address with the Deebot app?
I need to know where is the LBS located.
My DEEBOT is not
working.
I want to delete a 10pm schedule time. My husband used the remote first. When we bought it. How do I get rid of that time. Resetting the robot and deleting times does not work.
I guess the question is really. How do I reset my remote.
Hi Sarah,
In order to reset your DEEBOT, all you need is to press and hold the START/PAUSE button for 3 seconds. Then set the current time. Once the scheduling has set successfully, make sure you hear the *beep* sound 3 times from the device and the indicator light will turn blow after that.

My Deebot N79 approaches the charging station but then bounces back over and over. I have to place it manually.
My Deebot N79 stalled it’s self cleaning during the night. I rescued it next morning, It would not run, I put it on the charger for a while it showed it was charged. I set it to clean, everything came on except the the long roller brush. It ran for about 3 minutes beeped 4 times and quit.I have followed directions and taken apart enough to remove the brush and clean everything. I checked the movement of the brush as suggested, it does not turn. Is there anything else to do or have I burned up the motor?
Any help will be greatly appreciated.
Hi,
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.
Run the Demo on the robot and see if you hear the brush motor turning at the appropriate time. If the motor does not power up then it might be the module failed (although it could also be a problem in the electronics connected to it). If the motor does run and the brush doesn’t spin, then inspect the yellow hub of the brush for cracks, or excessive wear in the hole. Make sure when you put the brush back onto the shaft that you can spin the shaft manually by spinning the brush.
Thanks
My DeeBot N79S constantly stops during cleaning. It gives a false main brush malfunction. I own three main brushes, and tried them all, the problem remains.
Hi,
The problem was not in the brush roller, it was the front guidance roller which, even though behind the ball is a small area but it was full of bits of little stuff. I used a pair of vise grips and pulled the roller out with its casing and under the roller was the built up dirt & debris. Simple fix but all the posts led me to believe it was the brush roller not the guidance roller in the very front.
Sincere
I was given a DEEBOT N79SE FOR Christmas! I can’t find anything in the manual that tells me what the 6 buttons on the bottom of the remote are for (I did figure out the clock). I have pushed them to try & figure it out but now a circle is on the screen with lines up & down thru it (last button to the right on first row) & I don’t know what that’s going to direct it to do? Guidance would be appreciated – thank you in advance!
I cannot get it to reset or to just clean a specific room. Have watched a bunch of videos and followed the manual, I think its just not good anymore. 1 year of use. So bummed.
My deebot has a anti drop malfunction. It comes off the charger and immediately stops beeping 5 times. I’ve cleaned it multiple times but still not working. Any advice would be greatly appreciated.
Hi Kevin,
1. The Anti-Drop Sensors on the bottom of the DEEBOT may be covered with dust. Wipe the Anti-Drop Sensors with the brush on the left side of the Multi-Function Cleaning Tool to maintain their effectiveness.
2. The Driving Wheels may be tangled with hair or debris. Use the Multi-Function Cleaning Tool to cut off and remove any hair/debris tangled around the Driving Wheels.
If the problem is still there, please contact Customer Service.

My deebot won’t connect to WiFi despite the network is not 5G and instructions are followed, can you advise?
Hi Phoebe,
Activate the robot’s Wi-Fi
Press the RESET button for 1 second and then release. Make sure you’ve heard a beep or the prompt ‘Entering network setup mode’. After activating the robot’s Wi-Fi, the Wi-Fi indicator light starts blinking.
Connect the robot to home Wi-Fi
Meanwhile, the network information and password will be sent to the robot. The robot will try to connect to the home Wi-Fi.
iOS: Open the settings on the mobile device and select the Wi-Fi network starting with ‘ECOVACS’, then return to the App and wait for the network setup to complete.
Android: When activated, the robot will automatically start network configuration and connect to the mobile device. If the connection fails, you will need to open the settings on the mobile device and select the Wi-Fi manually. Select the network starting with “ECOVACS”, then return to the App and wait for the network setup to complete.
More Tips：
1. Make sure the connected home Wi-Fi network is a 2.4G or 2.4/5G mixed network.
2. Before configuring the network, ensure that the robot is fully charged. If not, place the robot on the Charging Dock for charging. You may configure the network while charging the robot.
3.The Wi-Fi indicator light under the robot cover (on the upper right of the robot power switch) is blinking.
4. Make sure that the power switch is turned on and startup of the robot is complete (there will be a startup ingle during startup, which takes about 20 s) before configuring.
5. Before or during the network setup, make sure to press the network setup button (the button is on the right side of the robot power switch and is a small dot and should be pressed for 1 second). You will hear a voice prompt.

Hi I have a question. I purchased a used ecovac n79, woth adaptor cord but no dock or remote. Is the dock the only way to charge this? And is the remote the only way to connect to wifi?
Hi K,
You can connect your Ecovac to Wifi using your smartphone, just download the app and set up .. then you can control the robot vacuum easily without using the remote.
But, you have to buy the dock to charge the unit.
Sincere
It’s not true remote is not needed to set up wifi. The remote must be used to set up wifi. So no remote means cannot use App. This is a bad design lapse.
How to fix my deboot n79 it always cleans at 7pm but I do not have it scheduled to clean. I have already done the pause and start button for 3 seconds.
Thanks
Lesa
Hi Lesa,
Please try the following steps:
1. Reset it – turn the side power switch to Off (“”o”” position) then 10 sec later to On (“”I”” position) again. Press and hold the auto button until you hear the beeping sounds-while it’s on the charging dock. Doing so will erase the settings from the robot.
2. Remove the battery from the remote control and put it back in again. Doing so will erase the settings from the remote.
3. If you want to set a cleaning schedule, set the current time on remote (clock button), then set the scheduled time (bell button), press Start/Pause button when you finish and DEEBOT should beep to confirm.

Hello- I have lost the remove of my N79 and am trying to reconfigure the Wi-Fi. I can’t find any button of how to make it go into the Wi-Fi searching mode. Is there a way around using the remote?
Hi Beth,
or some reason the WiFi network is not activated correctly when pressing the WiFi setup button the remote, it only seems to activate around 45 seconds after the second time you press it. Once I had figured this out I tried multiple different devices to complete setup. All I can say is use an old device or in my case a kindle fire 7. I had to side load the Ecovac APK but I got it to work finally! Ok so the steps…
Turn DEEBOT off.
Open app on Android device and accept any prompts.
Select DEEBOT N79 and accept WiFi prompt Follow app instructions.
Once you see connecting to DEEBOT wait 30seconds and hold the WiFi setup button on the remote for 3 seconds again!
You will see a notification in app stating it cannot connect, switching to manual mode (my app bugged out and did not show me the manual connection screen but I can assure it is running that portion at this stage)
At this point head to your WiFi connections.
The DEEBOT_**** WiFi should be broadcasting.
If not… start the process again or wait a further 20 seconds till you see the WiFi SSID.
Manually connect to the DEEBOT WiFi.
Switch back to the app and leave it.
You will eventually see setup complete.
You must keep the screen awake at all times. If it falls a sleep during setup ensure it is kept awake by removing it from its dock and re seating it.
This did not work first time at all so prepare for 20 minutes of faff! All I can say now is that Bob is fully integrated into Home Assistant how he should be 🙂
