Xiaomi Mi Robot - no tank detection 2in1 Viaomi V3, tank type recognition

Question

XIAOMI Mi Robot does not detect the 2in1 tank. It claims that a dust tank has been fitted. Questions: by what does it recognise the type of tank? Why is the detection not working properly?
I should add that I have a 2in1 tank from a Viomi V3, but it would appear that these tanks are the same.

Transfer two contacts, probably resistance. I'll be home in an hour and will measure the reservoirs

I will add that the water tank detects correctly, the problem is only with this 2in1 tank, so I cannot use the robot to vacuum and mop at the same time .

In my case it is as follows:- the 2-in-1 container has a resistance of approx. 12 Ω (does not detect, claims that a dust container is inserted)- water container approx. 6 Ω (detects correctly)- dust container, no ticks (detects correctly)Model: Mi Robot Vacuum-mop Pbut I have the containers from the VIOMI V3 robotAnyone have an idea why it doesn't detect the 2-in-1 container? Added after 1 [minute]: .Some report that they gave a magnet? second the question, how does it identify the type of tank?

DJ MHz · Answer

The water and 2in1 containers at your place have a small black magnet? Because I fastened the resistors alone it didn't detect anything my

And where can they be? I don't see any.

"Overview from AI

The Xiaomi STYTJ02YM and STYJ02YM hoovers, although different in name, are identical. In some cases, especially in the European versions, the hoover may detect the 2in1 tank as a dust container because the mopping function on the 2in1 tank is not available.
Detailed information:

Model:
STYTJ02YM and STYJ02YM are the same appliance. The "T" in the name of the STYTJ02YM appeared later, but does not affect the functionality.
European version:
Some European versions do not have an upgrade to the full mopping function on the 2in1 tank.
Detection of 2in1 tank:
In some cases, the hoover may detect the 2in1 tank as a dust container.
Upgrade:
If you have the European version, you may need an update to allow full use of the 2in1 tank.

Summary: If you have a Xiaomi STYTJ02YM or STYJ02YM hoover and it detects the 2in1 tank as a dust container, it is likely that you have a European version that has not been updated to support the full mop function on that tank."

So what to do? Change the software, no exaggeration I guess. However, is there a magnet needed somewhere?

DJ MHz · Answer

That little black dot on the removable filter is a magnet. Put the 2in1 container on without this filter, see if it detects by resistance. If not then it's something with the container. There is probably still a small water pump in it, if you have a higher resistance maybe it is banged up?

The other thing is I applied a larger magnet from the speaker then the robot detected the 2in1 without putting the containers on

@D.J. MHz And what kind of robot do you have? Maybe a different one to mine? Mine is a Mi Robot Vacuum-Mop P - the European version, not the Chinese one, and that supposedly makes a difference too.

I tested it and it looks like this:
1. when I give the 2in1 tank without the magnet filter, it detects nothing.
2. when I give a 2in1 tank with a magnet or with a filter that has a magnet, it says that a dust tank has been fitted.
3. when I give a water tank, it detects correctly that it has a water tank.
4. when I give a water tank and attach a magnet to it, it said there is a 2-in-1 tank fitted!!!!
5. when I apply the magnet alone, it detects nothing.

From this it follows that he must agree both: the resistance on the contacts, that there is this pump can, and there must be a magnet working?

I'm also puzzled by this resistance of the tank, because my 2in1 is about 12 Ω, while yours @D.J. Mhz wrote that it's about 4.3 Ω, which is just more like mine on water, which is about 6 Ω.

My model .

vivaldi_190 · Answer

@D.J. MHz you have the same Xiaomi model, so it follows that however this 2in1 tank from the Viomi V3 does not fit

"There is probably still a small water pump in it, if you have a higher resistance, maybe it is banged up? Is it bothered by the different resistance? A different pump?

DJ MHz · Answer

It's hard for me to say. The tank probably welded with ultrasound, maybe for isopropanol/extraction gasoline would take it apart. But I have one piece so I'm out .
