Robovac 11 sweeping brush

Photos!!! I would like to learn about.
A photo is more than 1000 words.

Picture of the motor in situ (post motor turn over)

Motor and belt drive assembly once out:

Take the cover off and the motor is mounted on two screws:

One motor showing the worn front bearing:

Looking at the little PCB on the end:

The voltage on the motor is 9v (not my assumed 6), body length (excluding shaft) 46.5mm, diameter 30mm and shaft 2.3mm.

Still no reply from Anker Support The sintered bearing is not standing up well to being turned over so I am going to have to look to buy a replacement in case the intention is that Robovacs are supposed to be disposable and not repairable.

Thank you!

If you search V700-L V02, you will find a bunch of these motors of similarity.

[jo.thoms]

thanks, I tried searching on the V700-L V02 but nothing came up.

Latest from Anker: They do not do spares, do not have a repair department and cannot provide me with any details for the motor… so their business model is that these are disposable items

Back to plan 2: I have found two very similar motors one on Fleabay (RS-395) and one on Amazon. I have ordered both. They should arrive by the end of January, don’t you love the speed of deliveries from China

In the meantime I can only hope that my beloved Sweep lasts that long. He’s been out this morning but the turned over motor still noisy.

[Chiquinho]

I was searching for this type V700-L V02 as well.
No result.

Plan 2 : Hope you will be successful changing the motors.
Of course both sides.
Keep us informed about your “research”.
Remember “old tinkers” never give up!

Ok Sweep is up and running again The cheapo £3 motor turned up from fleabay and has been fitted.

This is the old knackered motor at the top and the new one at the bottom:

First job, having noted which of the motor terminals is positive (red dot) remove the filter board from the end of the motor:

Solder the filter board back on the motor and checked the rotation of the motor by plugging it in the board and running Sweep up.

Then the tricky bit removing the gear. I tried a puller but to no avail and ended up cutting the shaft of the motor off and using my lathe to drill out the gear. (The attempt with the puller damaged the gear slightly )

The gear has been attached using Loctite 438, so it needs some time to go off. So final pic: New motor all fitted together:

To reward Sweep for all his hard work I gave his visor a polish so hopefully he will be able to see a bit better and finally relented and fitted his spare set of front brushes as they were getting a bit thin. Anker seem to sell these as spares but he has been used for 18 months so far on the first set, and so long as I steam them straight every month or so, they have been working well.

Thanks for the follow up and posting your repair. Kudos to you for taking this on and finding a fix

[Chiquinho]

Hurra: I like those repairs so MUCH!
Well done!

Hi all… I appear to have exactly the same problem. I have contacted Eufy support. My Eufy was delivered 9th Jan 2018, and today is 11th Jan 2019. I’m hoping that they will be kind regarding the warrantee considering it’s only a few days over (and the fault happened when I wasn’t home a few days ago and I just thought Eufy hadn’t found his way home and had just died in the middle of the floor).

I’m worried that they don’t have spare parts as that seems crazy! If they don’t help me out… Could you give me the link to the motor you bought? @jo.thoms I have a soldering iron but I’m not sure I’d not screw it up! Suppose for £3 I could try!

How annoying! I’ve been a real fan of this little vacuum and he’s been doing a great job.

I’m really hoping support can help me out. I don’t think it’s fair that for the sake of a little motor and 3 days I’d be that out of luck.

Hi Brian,

The one I have fitted came from Amazon. It has the same sintered bearing as the original. However I also ordered one of these: https://www.ebay.co.uk/itm/New-RS-395-DC-6V-12V-11700RPM-High-Speed-Large-Torque-Electric-Motor-DIY/392195324315?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
What is better with these is that they have a 1/8" shaft through the armature and the 3/32" where it goes through the belt driving gear = it has real bearings so hopefully with the sideways force will last longer. (I have ordered another 2 spares as they are cheap )

The only issues I have found is I think the Amazon motor I have fitted is a higher powered unit than the original so if used on carpet it doesn’t last as long. They also have standard 3mm rather than 2.5mm mounting screws.

Good luck getting the gear off. I was thinking of checking with a belt specialist to see how much they want for a replacement gear.

Jo

P.S. This looks like another of the sintered bearing ones: https://www.ebay.co.uk/itm/DC3-12V-Large-Torque-JOHN-SON380-Motor-Super-Model-w-High-Speed-Motor-2-3mm-R2Y3/282725049041?_trkparms=aid%3D555018%26algo%3DPL.SIM%26ao%3D1%26asc%3D20140122125356%26meid%3D29ae9bd3b8fb43ecbd0c4e740e38352e%26pid%3D100005%26rk%3D1%26rkt%3D9%26sd%3D253164370002%26itm%3D282725049041&_trksid=p2047675.c100005.m1851

Congratulations. As a technical model builder, I like such repairs. And perform them on my home as well. Starting from the iron plate - ending up at dish washers.
Very well done !

[Chiquinho]

Thank you for the links, Jo.

This saves a lot of time for other who have to do this repair.
The rest is not so difficult for us “old tinkers”.

[Brian_Saccente-Kenne]

Hey all…

I got my motor working again by just lubricating it. It had jammed, it would seem, with some dust. I am back up and running.

For what it’s worth… Eufy support wouldn’t help me as I’m 3 days outside of warrantee. And as you know, they don’t stock spares.

I have just found out, however, that Eufy 11 is the same device as the iLife A4, and there ARE spares for this on eBay.

Here is the replacement part in question here…
https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.fr%2Fulk%2Fitm%2F123551839490

I’m pretty sure this would work… Thought it worth sharing here.

[Chiquinho]

Great job you did,.
Many thanks to you!

I have just found out, however, that Eufy 11 is the same device as the iLife A4, and there ARE spares for this on eBay.

These two vacuums are Not the same, they may seem similar but are different. Not sure if parts will interchange due to the differences
The Eufy RoboVac 11 is a little bit wider than the ILIFE A4. Eufy’s robot vacuum measures 13 inches in diameter while the ILIFE A4 is only 12.2 inches.
ILIFE is also 0.84 lbs. lighter than the RoboVac 11. However, the Eufy RoboVac 11 cleans more efficiently than the ILIFE A4 and it has a bigger dustbin capacity. The RoboVac 11 can clean even heavy soiling, while the ILIFE A4 struggles with it.

This is a great thread, I think I have the same issue with mine.

Before I start on the great dismantling, any tips on taking Malkin apart (everyone seems to have a name for their robovac)? I saw one video online for an iLife robovac and that looked rather complex. I’m hoping the main screws on the back are all that’s needed to get at the motor

Thanks

[Chiquinho]

Do not hesitate to take a screwdriver.
If human “medici” would never have tried to open the human body
where our medical science would have stuck into!
Go on and let us know what you are detecting.

We are here, we are ready to help.

Mine here is little “Willi”.
Very busy since about 3/4 year, no issues as far.

[davidfarquhar]

Thanks for the words of encouragement… today I successfully dismantled and reassembled the robovac. Its actually easier than I expected, and I did manage to clean lots of dust out in the process. I haven’t fixed the issue yet, I was hoping it might not be the motor but it does seem that’s the issue. I have one on order from China and it should be here in a few weeks.

To help anyone else with the process, here’s a rough set of instructions

1. Start by removing the rotating brush, dust catcher
   and the yellow rotating brushes. At this point I popped out the roller ball at the front and removed all the fur around this

2. Unscrew battery cover and remove battery

3. Unscrew the 6 small screws at the bottom of the bumper. This allows you to lift off the bottom of the bumper

4. Pull the bumper away from the robovac slightly. There is a wiring attachment which can be removed with your fingers
   

   
   
   
   

5. The rest of the bumper can now come out easily enough

6. Unscrew the recessed screws holding the bottom / top together. There are 8 of these including the two just outside the wheels, plus a 9th screw just inside the left wheel as you look at it now

7. There are two small pieces of rubber glued to the outside of the body by the wheels. I peeled these off and didn’t put them on when reassembling
   

   

8. How the bottom can be gently lifted off and turned over. You can see the motor assembly on the right side. One screw and a wiring attachment hold this together - remove them and you’re ready to follow the instructions above

Have fun

[Chiquinho]

Great!
I love to see “real tinkers” at work.
I am one of the same.
NEVER give up.
Throwing away an item without any research is stupid.
Keep us informed if you succeeded to swap the motor.
