Thank you for this fix. I cleaned the tension belt with some isopropyl while I was at it. Was quite dirty. If it happens often I plan to solder a tiny terminals to the motor about it through to the dust bin area. That way I can do this “restart” trick without opening all the screws over and over again.

So far so good with this vacuum. kzfaq.infoUgkx8ISPQRRAfpAaX4msGjyodObTBnlj4T5g I was a little concerned to find it seems to be all plastic, but the reviews were good, so I'm hoping for the best. Very easy to assemble Recommened, and only attachments I've used so far work well, and are easy to use. Doing a good job on the new carpet in my bedrooms and stairs. Works well on the hardwood on my main floor too. Reasonable weight and cord length. I already knew from an earlier review that it wouldn't fit under furniture, but I can use my Eufy for that, so no problem - the high traffic areas that need a stronger suction was really what I bought this for. If it continues as it's started, it will be a good buy and well worth the money. I have had two Shark Rocket stick vacs in the past that are super easy to use, but the motors just don't last well, even with scrupulous cleaning of the filters. I'm hoping for better with this Bissell.

Thank you! Saved my family from drowning in dust)

You saved my life! Exact same model and same error message, follow the same process and it worked! Thanks for sharing!

This was a very useful video, simple and well explained, fixed by roborock and saved us hours of manual vacuuming 🙂

Excellent video, I was able to fix my robot while my children were watching TV. Extremely useful, and I love how the video is broken down in chapters. Great job!

I have been using this video for the last 4 years. I have been ordering the new laser sensor at Amazon for $10 and work for 15 months and then needs to be replaced again. Thanks

Thank you for help, restarting of the engine with battery helped me to avoid sending device to the service. 🙌

Thank you so much for this video. Tip for the S5 max owners. When removing the cover, there is the little port for your usb sitting on top. No need to unscrew. But the recharging worked like a charm.

Thank you so much! Was able to restore my s5 doing this exact thing. Appreciate the easy and quick video. Exact same issue and exact same fix! Thank you so, so much!

No way. This method actually worked for me as well. Thank you so much! By the way, no need for a cable for jump starting. The 9V battery is almost the good size to begin with, and you can just bridge the gap with a screwdriver or whatever - simply touch the motor terminals directly.

This just happened and I found this video. TBH was initially sceptical about it working but connected the motor via USB and lo and behold. It’s alive! Thank you so much for uploading this.

Omg finally i found this vid, thank you bro

Danke! Du hast mir leben gerettet! Freundliche Grüße aus Deutschland!

Thank you for helping, kind stranger! 🥰

Thank you! Instead of jump start the motor, I simply spin the motor a few times, clean the dusts, and make sure the connections are secured. Then, it works!

This was very helpful. Thank you. You are helping a lot of people with this video. Question: how did you connect the cables to the motor to power it? Did you solder them? Did you use any specific cables (from where you got them)?

Thanks for the instructions. This solved the error

Thank you! Very good video. It was spinning, but very slowly. It was caused by dust and hair entangled around the motor axis. Such thing can be the problem, so I advise that striping cables to check the motor to be a later step on the procedure!

Thank you very much for this video! My laser tower was full of cat's hair and the vaccum didn't move anymore (laser error). Opening the laser tower I could clean it well from hair and dust and the roborock works fine again!!!! So much time and money are saved thanks to you! 🤩🤩🤩

Thank you. It really worked again for 5 minutes but then stopped working again (again fault number 1) What do you think needs to be done?

Hey man, I tried this and it worked intermittently. Now I'm getting the same error again, and my robot is driving backwards and trying to clean before giving the laser sensor error. Any idea what could be the issue? I've dis and reassembled it a dozen times.

I sent this back to the manufacturer once before for the same problem and it took weeks to get it fixed through them including weeks of emails back and forth just to get the machine shipped....frustrating. THIS WORKED!!! It’s been running for the last half hour no problems... You are amazing and the video was not dreadful! Well done. Thanks a ton.

Outstanding....this Tutorial saved me a lot of money! No need to send my S55 to Service! It's ALIVE....motor was stuck and needes a jump start just like in your Video! Greetings from Germany

The problem is most likely the connector for the motor vs issues with the motor as suggested here. That is why the problem returns for some, and others claim by running the motor with a power supply fixes the problem when in fact, simply re-seating the connector fixes it, at least temporarily. I would first try (carefully) cleaning the contacts of the connector attached to the main body using a thin eraser or alcohol and ear swab first. I spent my career fixing portable surgical electronics and much of the time, simply re-seating things that does the trick. Do the easy stuff first before blaming the motor.

Great trick!!! thank you This solved the error. But I want to know the root issue because it happened again a few times. Very annoying

This worked for me with a 9V battery! Thanks a lot for your vid!

Thank you so much! My Roborock was working for 1,5 years, before i got this error, out of nowhere. This fix is easy and was successful for me.

Although this video could’ve been edited and shortened, it helped me fix my roborock. I’m grateful! Thanks!

Ive never done these diy fixes before in my life, but today i thought, why not. If it breaks it breaks.. been using it for so many years already. Followed ur video, and it actually worked! I was so suprised i actually yelled, it was such a great feeling Thank u so much for uploading this. It was so easy to follow.

Thank you for this easy to follow guide to revive my roborock, a simple defibrillation and it's alive once more.

Tried to start my S5 today, did not start up with same error. Googled your vid, took me about half an hour to do it myself. Worked perfectly, thank you!

Worked like a charm! Excellent guide chapter by chapter!

tq man! my robot is back to life again after i followed ur method to jump start the motor 👍👍👍

Helped! Laser Head was blocked by a tiny stone. Could hear the scratching. Cleaned. Working again. 🤗👍

Great video. I jumped the engine, now it works. Clear video, complete details, very good edition, complementary links and info; well done. Thank you.

I did this a year ago. It worked for about a year. It stopped working today. I did it again and it started working again. Thank you!

Your instructions are really "life-saving"! They solved my problem directly! Thank you so much! I did not understand why this problem occurs or how it is done and solved in this way. However, your solution works perfectly!

I don't know, how exactly, but it worked in my case. Thank you so much!

This video is a great help to save my robot! I‘m almost going throw away the robot thinking it is beyond repair since I have been using it daily for 2 years. Thanks for sharing this video instruction!

thanks for the video! used it on my Dreametech D9 Vacuum which is very close in design to this. Was able to jump start the motor and the vacuum started working again as it should!

I did the steps from your video and it worked! - my robot is now back in business. Thank you for the tip!

Surprisingly this fix works. I've cleaned the motor shaft because it was full of tangled hair and mounted it back. It was not working. After jump starting the motor with a 9v battery it works.

It worked!!! This happened to me twice. The first time I received the error it was covered under Warranty and the company send me a new LDS. Then it happened again 6 month later. Thankfully this did the trick!

Worked a charm. Thank you! For those of you using a usb, some of them don't have a black cable. The equivalent of this is the wiring that wraps around the red, white and green cable.

Thank you very much for taking the time to share your experience! The video is very straight forward to follow, and more importantly for me, it worked like a charm!

Great fix. I just had the fortune to find your video first and to jumpstart the motor was exactly what was needed for my s5 too. A complete no-cost solution. Do you care to explain why this happens and why it works to fix it like that? It's not anything I've ever come across before.

Awesome video ! For me it was only necessary to remove the top of the lds scanner and then clean it by blowing air

Thank you so much, I had this same problem and fixed it by following your steps. I used the USB cable and connected it to a powerbank, it worked perfectly. I tested it and it's working normally now. Thanks!

Thanks you so much! I just did the same and miraculously the robot began working. Gosh, so glad I found this video.

This totally worked! If you don't have a 9V, I found it worked with a C size battery awesome. Thanks so much OP, really appreciate it

Thank you. Very helpful. Worked a treat. Saved the cost of a new Roborock.

I really appreciate your guidance...I became a Roborock mechanic specialist...

Mine did the error one today and I ran across this video. You're a life saver! Thank you!

Thanks dude, just revived my S50 with a powerbank and an old cut off micro-usb cable thanks to you. Subbed :)

Followed this video and now my robot is working perfectly! Thank you so much!

It worked for me, I had some troubles connecting the red and black cable to the motor but found out that I could just wrap it around and it worked wonders. Thank you for this DIY fix you saved me a lot of time and money.

Thank you so much from Germany. In my case it was just the rubber ring that was not in position anymore. Fixed it and that was it.

Thank you, I followed this and then realised my Roborock actually has it's own USB plug for this very reason! Even easier.

Thank you for this video. A little 9v Jumpstart fixed my unit

This worked perfectly. Thank you very much for this informative video, saved us from having to send it to a repair shop.

Thanks again, 6 month latter again error 1. searched for this video again and haha it helped again xD

Thanks KS Toh. A good and clear repair approach.

Did it with USB, fixed the problem. Thanks!

Thanks! Really helpful, and it worked! The motor jump started and the laser thingy could work again.

Great video. Thanks for sharing. Saved my Roborock!

I've done it twice already. first time it broke was like a year ago. hopefully it works a long time again thanks!

Thankyou so much from România, I have done exactly the same and it started to work. You are a blessing and I thank you so much for your help and time. Thanks

Worked like a charm thank you 🙏

Thanks! My motor still worked perfectly with the 9V battery but not when installed in the robot. Replacing the motor solved the issue nonetheless, so I'd recommend to replace the very cheap motor in any case.

Giving the motor a jump start fixed my problem, big thanks! Took only 10min. :)

Thanks a million! It worked!!! I spent £7 to buy wires and 9v battery, that’s all:)👍👍👍🔥🔥

Thank you! This worked. I had to cut an old USB cable since I didn't bother to go buy batteries. So far, so good. It's been vacuuming for 10 minutes now without stopping. Amazing trick. So easy :)

Like many others down here in the chat, thank you for saving my life! This video is great! Robot is now working just fine again! Cheers!

Very good video, my warranty had run out so I had to fix it myself or pay for repairs. Worked wonders and it's in process of cleaning the apt as we speak. Thanks!

This is my first robot vacuum after much research🌼 and I’m so happy I purchased this. Wow! After one clean I didn’t realize how much dust had accumulated in my new carpet. Great for daily cleaning especially if you own a pet. I wish I would have purchased this sooner. Highly recommended!

Thank you! Fixed mine with this trick!

KS, you rock! Very simple instructions, followed it to the T and it worked like a charm!

We need more people like you. Thank you

Thank you for saving my friend Bobs life.

Mine had the error 1 message. Thanks to you, my Roborock finally works again! The motor from Alibaba took nearly a month to get here from China, but it was worth the wait!

Thanks. In my robot was some insect (larva) inside the laser sender. I just remove it. Works fine :) thanks for support.🙂

Worked flawlessly on my Roborock S6, thanks! My USB cable had no black wire, but its equivalent is wrapped around the other wires. And I used a USB adapter that’s able to deliver 9V

Thank you for your valuable video...... You are great. So happy for fixing our precious vacuum......so happy indeed.

Thanks, this video saved my Sunday!

Hi! Exactly the same problem and this video did the job! Really well done! Cheers from Portugal!

used these instructions second time. previous was ~7 month ago. fixed my robo-cleaner second time :) probably I'll need to change the motor in some time - but for now it still ok thank you very much!

Thank you so much! This video is clear and easy to follow. Got an error | on my S7 and all I had to do was reposition the drive belt.

Thank you so much 😊 from Australia. It worked. I would have never figured this out by myself.

I don’t understand how I should connect the usb cable to the motor. Have cut a USB and I have the red and black string, but how do I attach to the robot?

It worked for me. Thank you so much for the video. Save me from buying a new one

I had the same issue, now it works perfectly. Thank you for your work!

Thanks so much!!! Got it working again!! Had to google about USB cable that has 4 wires!

Thanks a lot! it felt like restarting a car battery hehe. You are a life savior!

20 km^2 cleaned and 3 years of almost daily cleaning for its first pit stop, not bad... i hope all the issues are easy solved like this

It worked!! Thank you for saving me packaging up a return to Roborock!

Fixed my error. I thought I was going to have to buy a new one. Thank you.

Amazing video - practical and very clear instructions! I was able to fix my roborock s5 with this video. Thank you so much!!

I used a USB cable and fixed it. Thanks so much!

It worked!!! Thank you 1000 times!!!!
