Without meaning to get too personal, what is the technique for using those? When I took a work trip to India the office had what I think you’re talking about. In the US, it’s like a sprayer on a kitchen sink. I didn’t dare try it out, as I couldn’t think of a scenario where I tried it for the first time and didn’t soak my clothes. I didn’t want that to be my reputation at the office.

You hold it relatively close to the area that needs cleaning. Adjust the pressure as needed using the control on the handle. Then use TP (just to dry), in my experience this is optional in warmer climates.

I have seen that 'mini shower head' in multiple homes and hotels in Finland and Russia (but not in Sweden or Denmark). It is amazing!!

A side-hack for that matter is to switch from plain-TP to wet-wipes. Some time ago I visited a friend who had younglings, and treated myself to a pamper-wet-wipe and it was amazing.

The sewage system won't be happy with wet wipes. Caused huge problems in some areas as it doesn't break down.
