Hello!

I understand that for wet vacuuming on the Karcher A2003 vacuum cleaner, the sponge filter is used. With the filter installed and even with the motor not installed on the collection bucket, immediately after starting, the valve at the suction mouth is raised, which prevents water from entering the motor, which cuts off the air flow of the vacuum cleaner, therefore the vacuum cleaner cannot be used. I tried without this filter, but water enters the motor.

With the blue bag filter, the air flow is also blocked because it gets wet.

I also tried with the cartridge filter, over which I put the sponge filter, over which I put the blue bag filter. The problem is that the cartridge filter is made of paper.

I am attaching pictures and a video.
