The water problem they have is very important, and we think that ALL the vacuum cleaners of these models must be modified , if possible before the first use in any way that includes scrubbing, to avoid the entry of water inside them and the problems That this entails.
From Vacuum Spain we recommend these modifications, but only you are responsible for applying them well and for any damage they may cause.
There are two versions of the 2 in 1 tank, they differ by the length of the water outlets.
Both deposits must be modified. The length of these water outlets are the main problem of water seepage inside the vacuum cleaner. They are too short and the water don´t fall directly on the mop, part of this water remains in the compartment where the tank is fitted, from there it filters through the joints inside the vacuum cleaner, causing serious problems in the electrical systems. Some sensor may stop working, cause damage to the motherboard, leading to a malfunction of the robot, for example, some wheel stops working, or your robot simply becomes non-operational.
To How to fix water issues in Xiaomi Mijia 2 in 1 STYJ02YM, Xiaomi Mi Robot Vacuum Mop-p, Viomi V2 Pro, Cecotec Conga 3290 Titanium, Cecotec Conga 3490 Elite, Cecotec Conga 3690 Absolute, we have to lengthen the outlets of water, for this we are going to give you a solution for each type of tank and an alternative.
ISSUE FOR TANK WITH LONG OUTPUTS:
This is the best solution, pieces printed with 3D printers. We leave you a link with the 3D models created by LatchyRed , there are 2 versions, one for each tank version, in the design properties you can see which one is appropriate for your tank:
To print them yourself:

Other ideas to lengthen the outputs while you get the 3D pieces.
You can adapt any idea that you can think of to lengthen the water outlets, as long as they do not force the material of the water outlets, let the tank enter correctly (click to insert it). We propose you some ideas:
SOLUTION FOR DEPOSITS WITH SHORT OUTLETS:
Silicone rubber hollow parts 6mm to (0.24 inch):
In the tank of short exits it has not given a good result lengthening the 3D pieces since they have to be glued and any blow can cause damage to the tank, therefore the best solution that has been found is to put some hollow rubber pieces, which They place in the holes at the ends of the compartment where the tank is fitted, make the water outlets fit perfectly and under pressure, and ensure that no water escapes. You will have to enlarge the hole of the hollow piece of rubber by cutting a little the part that will be protruding from the hole. You can look for them in a hardware store or then I put a purchase link, they must choose the model 6mm a (0.24 inch).
ALTERNATIVE WHILE YOU GET THE RUBBER HOLLOW PIECES:
6 x 35 mm anchor.
Cutting these anchors to a length of 14mm from the head, they will do the same function as the rubber pieces, but not being so flexible they will seal the hole worse. Therefore, although they are easier to get, we recommend that you use them temporarily while you get the 6mm A (0.24 inch) hollow rubber pieces.
OTHER IMPORTANT MODIFICATIONS:
If your mop covers the holes in the mop holder where the water should come out, you should cut that area of the mop adjustment strip to allow free water flow to the mop. Do it as seen in the image.
Another way to get water into the robot is by condensation, by the Venturi effect, from the wet mop during scrubbing, water rises through the holes. You have to cover the unused holes of the compartment where the tank fits, it is useful using a piece of insulating tape covering the two center holes of the compartment where the tank fits and the four center holes of the bottom of the vacuum cleaner, as seen in the images:
With these modifications we will avoid the entry of water from the robot. If at any time they see water in the robot again, you must check that the tank don´t have water leaks due to any union. We hope it helps you and that we save you some other problems. Thanks to Gulli, Alez, Ivan and Javi for helping with this guide.
