Humanity has come up with an ingenious and simple solution, in fact, as it happens. Among other things, it is also "green", that is, environmentally friendly and well thought out from the point of view of ecology and, as in this case, water saving.
The WashUP washing machine offers an excellent solution to save water. It is hung or fixed over the toilet and can really save water. The principle is this: the washing machine works as it should, so that later it flushes the water in the toilet later.
The savings are obvious - instead of pure water, one is being spent that no one will use for sure! And as a bonus, if you suddenly run out of toilet paper, you can replace it with a washed shirt or bathrobe. It's a joke, of course, but it's an option …
An amazingly simple, convenient and truly ingenious solution! Really it was impossible to come up with it earlier, because so much water has flowed under the bridge, as the proverb says. Plus, such a system significantly saves space. If you usually need to look for a suitable place for a car, then everything is simple. Like everything ingenious.
