ᐅ What is this hole in the toilet bowl for?

Hello,
I recently won this new toilet bowl on eBay (wall-hung toilet). Inside the bowl, where the water will sit later, there is a strange small hole about 2 cm (0.8 inches) in diameter (see picture).
What is this hole for?
What additional materials are needed to use this hole?

Regards, Andreas

In this hole, a nozzle can be installed that is activated when flushing. It sprays a strong jet of water into the toilet bowl to flush it thoroughly. These toilets are commonly found in the USA.

It seems not only the portions are larger there.

larger, more solid, more compact

As long as no high-pressure cleaner is connected that could cause damage!

Hello Andreas,

You can usually get these nozzles at specialized retailers (e.g., Richter and Frenzel) or order them online.
Just try searching for them.
