Einleitung
Wenn der V7S vier mal piept, bedeutet das, dass die zentrale Bürste nicht mehr rotiert. Er dreht nur noch ein kurzes Stück rückwärts und bleibt dann stehen. Wenn eine normale Reinigung nicht ausreicht (Reinigung der zentralen Bürste, des Staubbehälters, der seitlichen Bürste, des Vorderrads) ist es an der Zeit den Motor/Motorraum zu reinigen.
Fremdkörper verhindern den Antrieb der zentralen Bürste.
In dieser Anleitung wird der iLife V7S zerlegt und das Problem behoben. Das Problem kann nicht durch eine neue zentrale Bürste behoben werden.
Was du brauchst
-
-
Schalte den Roboter an dem Powerknopf (Kippschalter) aus.
-
Entferne den Staubbehälter.
-
Dreh den Roboter auf den Rücken.
-
Entferne die zentrale Bürste (auf dem Bild ist sie schon entfernt).
-
Entferne das Vorderrad (herausziehen). Reinige den Sensor unter dem Vorderrad (dunkler Plastiktropfen unter dem Vorderrad). Entferne den Schmutz und die Haare von dem Vorderrad. Das Rad kann noch von dem umliegenden Plastikteil entfernt werden, dazu muss das Rad herausgedrückt werden.
-
Schraube die seitliche Bürste los und nimm sie heraus (oben rechts).
-
Entferne alle Schrauben, die darunter sitzen. Die mittleren beiden haben Plastikhülsen, die ebenfalls entfernt werden müssen um den vorderen Stoßfänger zu entfernen.
-
Entferne die Akkufachschraube, die Akkuklappe (unter dem mittleren Rad auf dem Foto) und entferne den Akku, indem du sie zuerst an der speziellen Schlaufe auf der Batterie heraushebst und dann das Anschlusskabel von der Platine löst.
-
-
-
Wenn die zwei Schrauben mit den Plastikhülsen gelöst sind (größeren Löcher auf dem Foto) ziehe den vorderen Stoßfänger vorsichtig aus dem Staubsauger heraus.
-
Zieh vorsichtig an den Kabeln und löse den Anschlussstecker.
-
-
-
Entferne die obere Abdeckung.
-
Entferne die zwei Schrauben an den "Bumper-Armen" (die größeren Schrauben rechts und links von der Hauptplatine).
-
Entferne die "Bumper-Arme", aber ohne die Federn zu verlieren (Auf dem Bild ist de Hauptplatine schon entfernt, das wird im nächsten Schritt beschrieben).
Hi. What componet is L7?? Is near to the speaker and diode D2.
I need the electronic schematic.
Thx!!!
-
-
-
-
Löse die Stecker vorne von der Hauptplatine und löse die 4 Schrauben, die die Platine befestigen.
-
Kippe die Platine auf die andere Seite, um an den Motor der zentralen Bürste heranzukommen.
-
-
-
Jetzt müsstest du das gleiche sehen, wie auf dem Bild dargestellt.
-
Zieh den Stecker der Stromzufuhr zum Motor und merke dir, wie es angeschlossen war.
-
Sobald alle anderen Teile entfernt wurden, kann der Roboter auf die Seite des Tisches oder auf die Knie gelegt werden und die Motoreinheit von der Unterseite der herausgezogen werden.
-
Nutze deine Finger um die transparente Klappe durch die Öffnung zu drücken während die Motoreinheit herausgezogen wird.
-
Wenn das Motorfach von der Einheit entfernt ist, schraube die drei weißen Schrauben von der Seite des Behälters ab, um das Hauptgetriebe und den Riemen zu öffnen. Entfernen den ganzen Staub und die Haare und schraube noch die 2 kleinen Schrauben, die den Motor befestigen, los.
-
Wenn der Motor entfernt ist, verwende eine Pinzette, eine Nadel oder etwas Ähnliches, um Haare und Staub hinter dem Motor zu entfernen. Sobald alles sauber ist, gib etwas WD40 auf das Plastikgetriebe und gib vielleicht einen Tropfen hinter das Motorzahnrad. Sprühe NICHT auf den Motor oder in den Motor. Dies kann zu einem Feuer führen!
-
-
-
Du kannst vorsichtig die Rückseite von dem Element ablösen und vom Schmutz befreien. Du kannst dazu am besten einen großen Schlitzschraubendrehen verwenden.
-
Nachdem Reinigen des Lagers kannst du etwas WD40 ans Lager geben.
-
Beim Zusammenbau kannst du den Zahnriemen sehr einfach auf die Zahnräder legen und zum Schluss die Rückplatte mit den Schrauben auflegen und die Rückseite auf die Rückplatte drücken.
-
-
-
Baue alles wieder zusammen, indem zu der Anleitung in umgekehrter Reihenfolge folgst.
-
Du bist fertig! Der Staubsaugerroboter funktioniert wieder!
-
Während dein Staubsaugerroboter wieder an die Arbeit geht, genieße ein kühles Bier aus dem Kühlschrank.
-
Genieße das Bier während dein Roboter seinen Job macht.
-
Du bist super!
-
Danke, dass du meine Anleitung gelesen hast!
Unfortunately it didn't work :( any more suggestions?
спасибо за ваше подробное описание и за фото! очень помогли. я всё прочистила, моторчик смазала. робот теперь двигается, но, к сожалению, не прокручивается центральная главная щетка. . завтра еще его попытаю..
All dust remove, and still motor gear doesn't spin at all… I have to put so much energy to roll this brush…
Maybe the bearing of the brush is stuck. Did you check this already? If the brush bearing is fine, is turning the motor gear easy?
Wheb testing make sure to put dust bin inside. Mesh screen filter must be installed indise the dust bin.
If still doesn't work try again, there must be mosre dust and hairs stuck some where, pay attention to step 5 and 6 and make sure you put the belt on the gears and it works. This belt drives the main brush.
Alles auseinandergeschraubt, gereinigt und Motor durch neuen ersetzt (Zahnrad war abgebrochen). Krümel reinigt wieder als wäre er neu. Vielen Dank für die sensationell gute Anleitung, der selbst Hausfrau folgen kann.

Thanks for did it!, I’ll try do this, I hope won’t screw up :)
Good luck! Just be gentle with the board and make sure to remove all hairs from behind the motor gear. Also on Step 5 pic #2 you can check the gears in the side part of the brush housing (three small screws). There is a small possibility some dust made its way there too. There is a belt inside, that could be tricky to put back in place but nothing difficult.
Also you can tune your vacuum by removing the ballast extending work time and making it easier for robot to move around. You’ll find ballast behind the brush tray close to the vacuum fan. The ballast is 5x5x0.5cm metal plate attached with double sided tape inside the vacuum. All you need to do is stick something sharp between the ballast and the side of the tray and remove the double sided tape. After the tape is loose gently pull out the ballast up with pliers. Removing ballast will make your robot ~100gm lighter that equals to a full tray of dust and hairs. Robot will run betterweeping longer on a single charge.

Check this link to see what the ballast looks like:
What is inside Chuwi Ilife V7 vacuum cleaner?
See step 2 pic #2, the ballast is the silverish plate pictured behind the wires on the photo.

Thank you for your detailed description. This saved my (i)life!
Hi
After repairing the robot goes onli back and stop after 5 seconds
You need to complete the teardown COMPLETELY. The behavior of the robot shows that there are still hairs inside.

My side brush does not work anymore, motor is oké, tested it.
Wiring of the motor is oké also.
Looks like its not getting power from the print.
Any suggestions?
Thanks so much for this! The problem was solved perfectly! :D
Just wanted to thank you!
My ilife stoped working, and i was going back and forth with the Gearbest support center. They were les than helpfull, so i decided to google the problem and found your guide.
Im glad to say that i follow all the steps and my ilife works like a charm. somethimes it does a litlle screeching sound but i believe it was because i skipped the WD40. My bad. i will follow the guide again and apply some.
Anyway thank you so much, you are an (i)life saver,
Greetings from Portugal
Vanessa Chaves
Hei! After cleaning and backset, vacuum do not suck up dust anymore, all dust on around in the broom and dust bin is emty.
Hey secretdina2000,
I’m sorry that your chuwi doesn’t work like expected.
Please doublecheck all the connectors to the mainboard, maybe one is not connected. If you just put the case off and leave the dust bin inside you can check if the vacuum engine works at all.
Keep me updated, we will figure out what the problem is and solve it =]
cheers
Lukas
Great guide that was very easy to follow without any complications whatsoever. Followed it to the letter (including the cold beer at the end) and my robot is now taking care of cleaning our home while I’m writing this.
While I do understand why these things aren’t covered by the user manual (and not many people feel comfortable taking things apart) I have to wonder what everyone else do when faced with these problems? That’s a lot of money going into service…
motor was broken. :-((
motor model is: standard motor rp390-st/20143.
Do you sell this? Or any clue whe I can buy it?
Thnks
I replaced my brush motor with one from aliexpress “Mini 385 DC 12V Motor 14500rpm Shaft Diameter 2.3mm Front Ball Bearing Powerful Micro Motor With Wear-Resistant Carbon Brush”. The brush is now faster and I think louder then before. I had to use some spare screws because the original ones are to small. I’m still looking for another motor, but it seems that there is no other motor with a bearing and 2.3mm shaft.
I’m trying to enable this 12V 13000 rpm Strong Magnetic Large Torque 390 motor Drill motor https://www.aliexpress.com/item/32892019...
Hey, this is a great guide! Can it be used also for solving the 4 beeps issue of the iLife A4S?
Hey erlutzu,
I think it is very similar. With this guide and maybe this: “ILife A4 Robotic Vacuum - main roller brush bearing replacement” youtube video you will be probably successful.
Good luck!
Hello, my robot run back and stop, i do everything by your instruction and doesnt help :/ … mystery is - if i unplug turbo brush motor cable from motherboard .. robot run perfectly … what can i do ? .. thank you
Same here. I have changed from original motor to new 12V 13000 rpm Strong Magnetic Large Torque 390 motor Drill motor because of original was broken and stucking.
Motor works, brush roles, but unfortunately just a second, then backwards, then stops, and blinks red.
I think i soldered wrong or something wrong with motor control board?? ilife doesn’t work with main brush motor enabled. So now disconnected, using only Wet cleaning. Does anyone has ideas of problem? Can someone provide screens how it should be connected (Made mistake of not taking pictures before dissamble)
Model that i purchased: https://www.aliexpress.com/item/32892019...
@dkvadratu Did you solve your wiring? Did you test the motor just connected to the mainboard without complete installation with the brush? I think if you did the wiring wrong the motor should turn the wrong way around, maybe that is the issue?
thanks for help man! Maybe a little bit more detiled photos. After asembling all it still had the issue. But we noticed that when we took it upside down the rolling main brush did not roll. We helped it manually and it started to work!
Thanks for this, it helped me assemble my vacuum back, but now for some reaosn when i turn it on it keeps going backwards and accelerating. like trying to escape from being stuck, my guess is that something is wrong with the sensor or front bumper… but i can’t tell because it looks fine when i disassemble it again…
I did it!!
But one of the last sentences I don’t agree! I’m a woman and I don’t like beer…..
Nach Zusammenbau funktioniert die Bürste noch immer nicht, außerdem fährt der Roboter jetzt rückwärts. Nach kurzem Rückwährtsfahren und Hüpfen kommt der Fehleralarm. Was kann ich jetzt noch tun???
Teste einmal ob der Motor überhaupt noch funktioniert. Also Motor ausbauen und an wieder an die Platine anschließen. Den Roboter wieder soweit zusammenbauen, dass er startet und schauen ob der Motor sich dreht. Du brauchst den Roboter nicht wieder mit dem Cover zu versehen, aber du musst den Staubbehälter einsetzen, damit er startet.
Halte uns auf dem Laufenden.
Hi and thank you for such detailed tutorial.
I believe my problem is a bit different, however. My robot does not beep - it continues to run but the brush does not rotate. I tried to understand why and it seems it stops rotating only when the brush is in place or after applying some pressure in the rotating holder.
I just found this tutorial, but I did open it up before and cleaned everything. Should I also try to check the motor? The strange part is that it does not beep…it keeps on running, but doesn't clean as the brush is not rotating. I checked the brush, cleaned the bearing and even applied some wd40. Same thing happens. Could this be a motor problem as well, or simply replacing the brush would be enough?
Any ideas?
Thank you,
Pedro
Hey pedrodiogoum,
I think you can easily check if your motor is faulty. Just open the robot up again, put out the motor and leave it wired to the mainboard. Then put the robot back together so all wires are connected and start the robot. The motor should start turning. If it does not your motor needs to be replaced. Some time ago I posted where you cen get a replacement motor that is not as good as the original one but it is cheap and does the job.
I hope that will help you. Keep us informed with your progress.
Cheers
Lukas
Hey, Lukas,
So, I did open the robot, thoroughly cleaned everything (all possible bearings), applied wd40 and it still is malfunctioning.
I did not, however, tried your method of having the motor out of its normal housing and then having the robot working to check if the motor was working properly. However, I did check the robot working without the brush and it works fine - no beeping and it seems the motor is always working as the plastic bit that makes the brush rotate works non-stop all the time. It just stops once the brush is in place (stops rotating after 30s…)
I am writing you now this feedback as I just got a brush replacement (the other had the bearings in not so good shape, so I figured that was the problem), but it is all the same. At this point, I don’t see what else I can do. Could it really be a motor thing? Do you have other ideas? Don’t want to buy another one as this feels like something I can solve without spending too much $…
Thank you very much in advance,
Hey Pedro,
without a broken motor I can only think of the possibility that the space for the brush is too small. That can happen, when the gear from step 6 is not completely in it’s original position. I usually put the belt on the motor gear and hold the belt in a position that the gear for brush fits in the hole, then before rescrewing the back plate of the gearing room press the side where the brush get’s in place later and the back plate of the gearing room very tight together (with my fingers) and rescrew the back plate, but not too tight. I test it by putting the brush in place and I should be able to turn the brush easily. If the brush is stuck in it’s position the motor cannot move it and you get your 4 beeps.
Keep me updated on your progress and best of luck!
Hey Lukas, thanks a lot for this.
Actually, I never have the 4 beeps… the robot keeps working, when the brush stops rotating.
Attaching some videos showing how the motor is. Do you think this is normal? Not sure this is supposed to happen… https://photos.app.goo.gl/EdDM2qoTeaSxjv... (make sure you have sound on).
Again, thanks a lot for all your help!
Hey Pedro,
the gear ot the motor should not move in sideways. Mine did the same and made horrible noises. I think the motor is the problem. High quality motors have a bearing for that. Sometime earlier I explained which kind of motor I bought for replacement:
I replaced my brush motor with one from aliexpress “Mini 385 DC 12V Motor 14500rpm Shaft Diameter 2.3mm Front Ball Bearing Powerful Micro Motor With Wear-Resistant Carbon Brush”. The brush is now faster and I think louder then before. I had to use some spare screws because the original ones are to small. I’m still looking for another motor, but it seems that there is no other motor with a bearing and 2.3mm shaft.
That's perfect, Lukas, thanks!
After numerous emails sent to gearbest, they finally decided they cant provide me with a motor, but can reimburse some.
Went to AliExpress trying to find something and found these two:
https://a.aliexpress.com/_dWDzjBD
&
https://a.aliexpress.com/_dYVrZU7
Would any of this be a good alternative? If you can share some links, I would be greatly appreciated :)
Thanks a lot for everything!
Pedro

Sorry, I don’t have more information to provide.
I would try a motor with bearing, so the motor lasts longer, and that above is my experience.
Maan i got till the last part , cleaned everything and still get 4 beeps :(
Hey i just opened it again and tested the motor , it works fine :( its not bad.
I got it working, i did put the container with the chip inside :) ( only the container) (had the net filter removed for cleaning…)
Hi I was hearing 4 beeps, did all the steps you list. Now it works with no beeps but brush doesn´t rotate. I re checked that I connected the motor and indeed is connected. Any hint? THanks a lot
Does the gearing turns when the brush is not in place?
Maybe the brush sits too tight. When you put the ilife back together, make sure you press the part, where the brush sits in, to the side of tbe robit, that the brush has enough space to be turn by the gearing. You can do that step without disassambling the robot.
Hope that helps.
Lukas
Ich habe den Roboter auseinander genommen und habe ihn wieder zusammen gebaut. Jetzt ist er gerade offen für die Fehleranalyse. Vielleicht kann mir jemand mit dem Ton helfen? Was soll das bedeuten?
Hier ein Link zum Biepton https://drive.google.com/file/d/1nFn75LU...
———————————————-
I made it through this tutorial but now my iLife only beeps. Can somebody help?
Moinsen,
vielleicht ist es der Klassiker: Staubcontainer nicht eingesetzt.
Falls dieser schon drin ist könnte es der Sensor dazu sein. Als Test könntest du dann einfach die Kabel der “Containersensoren” vom Mainboard lösen. Genau weiß ich nicht wo die angeschlossen sind, aber man kann ganz gut dem Kabelverlauf folgen (vll ist es auch nur ein Sensor).
Gruß
Lukas
Moin Lukas
erstmal danke für die schnelle Reaktion. Der Container ist drin. Kabel dazu auch angeschlossen. Habe auch eben nochmal geschaut, passt eigentlich soweit.
Hast du das Video mal angeschaut? Wäre voll gut, wenn wir da gemeinsam ne Lösung fänden. Würde unsere “Pinkie” gern wieder in Betrieb nehmen können. Der Dreck ist entfernt - war auch echt nicht grad wenig.
Hab den Fehler gefunden. Am einen Sensorstecker ist ein Kabel durch… Ist mir wohl gestern beim Ausstecken passiert :(
Hast du ne Ahnung wo ich da evtl. ein Ersatzteil her bekomme.
Fehler gefunden! Das ist meist am mühsamsten. Ich würde es zunächst provisorisch reparieren, was dann zur Dauerlösung wird. ;-]
Achte eigentlich nur darauf, dass das abisolierte Kabel keinen Kontakt zu den anderen Anschlüssen hat.
Es ist schwierig in Worte zu fassen:
Tüdel das rausgezogene Kabel mal etwas von den anderen los und isoliere das Ende soweit ab, dass du das abisolierte Ende durch das Loch am Plastikstecker durch geht und versuche dann mal den Stecker drauf zu stecken. Das abisolierte Kabel darf aber keinen Kontakt zu den anderen Steckern haben.
Falls das nicht gehen sollte, weil die Lücke mit durchgezogenem Kabel zu klein ist würde ich das abisolierte Kabel zu einer Schlaufe formen und um den entsprechenden Pin stülpen und dann noch ein paar mal verdrillen, sodass das Kabel nicht einfach zur Seite weggezogen werden kann (eventuell das restliche abisolierte Kabel mit Isolierband [zur Not Tesafilm] sichern). Dann einfach den Stecker drauf schieben, der Müsste das Kabel an korrektwr Position halten.
Sonst fällt mir nur der örtliche Elektrofachmarkt ein (Conrad oder Omega). Vielleicht auch ein Fachmarkt im Modellbaubereich.
Ich würde es aber wahrscheinlich einfach für Immer provisorisch lösen.
Sag gerne Bescheid, ob und wie es geklappt hat.
Leider ist das Kabel direkt am Stecker abgebrochen und da ist ja auch noch ne Klammer im Stecker. Echt doof. Neuer Stecker ist bestellt und kommt hoffentlich bald.
спасибо за ваше подробное описание и за фото! очень помогли. я всё прочистила, моторчик смазала. робот теперь двигается, но, к сожалению, не прокручивается центральная главная щетка. . завтра еще его попытаю..
попробуйте все сначала, скорей всего остались волосы на шестеренка моторчика (шаг 5) или под шестерней в чёрном коробке сбоку от трея для щётки. ещё вариант что ремень внутри коробки не встал на шестерни.
Slava -
Awesome article. I had the same problem with my ILife v7s pro and after strictly following each step, now it is working as a new! Of course it took me 2 hours to fixed, but who cares. :)
Hi, thank you VERY much for such detailed description!! It all worked and now we can enjoy cold beer! Thanks again!!!
Thank you very much !
It worked perfectly and saved our « Piggy
Mega coole und gut strukturierte Anleitung.
Wollten das Teil schon aufheben, war echt die Rettung.
Auch wenn ich das Ergebnis bei einem Glas Wein genießen musste
Thank you for the great manual! This was the second time I open our “Robbie”, first time it was failing sensors.
Cleaned all the dust and hairs, works like brand new, no squeaking sounds and brush rotates great.
Sincerely happy for you. This is a great bot, the batteries lasst forever and it does pretty good job cleaning floors.
Slava -
For everyone experiencing issues with the main brush after following the guide. Please make sure to pop the gear off (step 6) and remove all dust and hairs from underneath the gear. Next thing is some hair stuck behing the metal gear on the motor. (step 5) there is a possibility of dirt going quite deep inside. Be careful and pull everything out.
Once everything is cleaned and before re-asembling the robot put the motor back in tray and assemble the gearbox. It is very important to make sure the belt inside gets fitted poperly. You need to stretch it in between the gears and close the lid. Once done, try to rotate the main brush and see if this movement is transferred to the metal motor gear. Point is to check if the belt got installed poperly and it works.
One Last thing. Try to rotate the motor gear to see if it can be rotated by fingers. I had to replace this motor once already as it was wearing out the bearing and the axle was getting stuck and it was difficult to rotated it. The motor often comes with the brush tray, it can be purchased on aliexpress.
hi! not strictly related to this tutorial (which is great by the way!) but, it has happened my robot lost - have no idea why or how - the score that fixes the side brush.
Would you be able to tell me what type of screw it is?
Hi, no idea what thread it has but specs I measure are following.
1cm tall (thread and top part)
2.5mm diameter with thread (max diameter with thread)
7.7mm tall threaded part
6-7 grooves of thread on 7.7mm part
cool, thanks for the quick reply. I hope I can find one to replace it!
Also check if your screw is inside your bust bin. It might’ve been picked up by main brush and placed in the dust bin.
yeah, I did that first thing, but it was not inside it
I’ve been cleaning my iLife v7 couple of times without result and then found your instruction how to access main motor. Gear room has incredible amount of hairs and dust, main motor gear was completeley stuck and rusty. After careful cleaning and lubrication - IT WORKS!
Thanks a lot! Cпасибо )
Very good 9/10 I had A bit trouble with the right two connecters I just guessd, the center wheel cable is the upper connecter. there was no connector on the motor it self there is one in the photo and there are probably many of this model were it is but I didn't have one maybe I have a later or newer revision sometimes they make minor changes because of cost idk and u have to make sure u clean the brush from the inside to. u can dis asemmble it further in to very small pieces with a flat head and some force I had very much dirt there or u buy a new brush
Hi guys,
I believe there was another question about what to do even if you did everything in the guide and still get 4 beeps: this likely indicates that the problem with the main brush motor persists. The small black gearbox needs to be cleaned. Make sure to PULL the large gear up to clear space underneath it. The main brush motor may also have some hair stuck between the motor and the small metal gear on it. If this still doesn't work I'd recommend trying to replace this motor. They're available on Aliexpress for like $15.
Hi, I have a similar problem but the guide didn’t work: the iLife starts cleaning normally for 1-2 minutes, then stops, turns around, the home button goes red and it beeps four times. If you start it again it beeps already after 30 seconds. The problem also exists if you let the iLife “clean” without the main brush inside, the problem doesn’t appear when the vacuum is in the “home” mode and on its way to the station. What can be the problem?
Hi Lisa, this must be the same problem and using this guide (cleaning the bot or replacing the motor) will work. 4-beeps mean that the bot cannot turn the main brush. What you are observing is likely that when the bot is fully charged, it can rotate the brush for 1-2min (with max battery charge and voltage). Once the battery power dips from 100% it can't overcome the resistance of dirt and hair stopping the brush therefore it starts reporting the error right away within 30 seconds after activating it.
Small update: I've had to replace the brush motor and the vacuum air pump previously, in case your bot is making a whining noise this means the air pump is getting worn. When you take out the main brush motor make sure to inspect and clean the gears (in a small black box on the side of the brush tray, there's a belt in this box as well) and check the motor. After years of service, the motor shaft may have worn out the hole in the motor housing rubbing metal on metal preventing the main brush from rotating.
Also, I was able to order replacement parts for this bot from the manufacturer's store: Ilife Official Store however the shipping time was quite long 1m+ but they were able to supply all parts (I suppose they carry the spare parts since they still sell the V7s Plus model that is almost identical to the V7S pro) ☺
Thank you for the quick response! I will try!

Hi,
mine v7s plus just broke down. Main brush is not rotating. It rotates for few seconds and then stops, robot will still go around, but its not able to pick up dust. I teared it and cleaned everything, but still no result. I have a spare v7. I changed the main brush motor (it is a bit different) and then it started very strange behavior: it goes back a bit, then turns and again goes back. Sometimes it stars beeping. When I unplug main brush motor. Robot works without any errors. Finally i took spare motor and soldered it to v7s plus PCB, so strange behavior wont start. But still after few seconds motor stops to spin. Any ideas what can go wrong? I can't understand how a connected motor can cause strange behavior (maybe it draws too much power?). I red that more people encountered this, but noone posted the solution. Hope this topic is still active, as I want my v7s work!
this behaviour is consistent with the bot sensing that the brush doesn't turn. Check and clean the black gear box on the side of the main brush assembly, make sure to pull the bigger gear off (gently with screwdriver between the base and the gear, it will require a bit of pressure).
If this doesn't work and gears and belt are clean and rotate freely, perhaps check fpr anything else that may cause the main brush to stop or resist rotating.
As you're at it get a magnifying glass to check the main board for rust, shorts or any signs of water.
My bot finally succumbed to water damage and replacement board was newer version that loops the charging eventually motivating me to give up V7S and get a new bot.
Gear box is already cleaned and spinning freely. Couldn't find any water damaged either on the board.
Raksim -
still not working. Found out, if i take it to my hands, start the robot then main brush spins until i touch it with my hand, after that it doesn't turn on.
Raksim -
Tolle Anleitung, die die Arbeit sehr erleichert.
Alles gereinigt. Trotzdem 2 Töne (Sensorfehler !?)
Was kann ich sonst tun ??
Danke für Tipps
frank
Beim Chuwi bin ich nicht mehr so fit. Meiner Meinung nach sind es nur vier relevante Sensoren: 1. der Absturzsensor an einer Stufe, der müsste an dem vorderen Unterboden des Chuwi sitzen. 2. Der Front-Bumper, dieser könnte "hängen". 3. Radsensor: Wenn man den Chuwi anhebt und die Räder entlastet sind. 4. Sensor, ob der Abfallbehälter eingelegt ist.
Einfach alle Punkte einmal auf Sicht prüfen und eventuell mal aktiv auslösen lassen. Gerne kurz eine Rückmeldung geben, falls sich mehr Informationen ergeben. Im zweiten Schritt nochmal die Verkabelung im Roboter prüfen, aber vielleicht irgendwo ein Kabel blank, gebrochen oder nicht angeschlossen ist.
Viel Erfolg.
Thank you for posting, it helped me!
