If we have a fish pond, of course, sometimes we need to clean the water because of the large amount of sediment in the pond.
In this cleaning process, we only need to suck up only the bottom of the pool without having to throw away all the water, because to fill the pool completely requires a large amount of water.
If our pool is positioned higher than the disposal site, of course it's easier to just drain the bottom part by sucking it using a hose and the end of the hose is directed to the bottom of the pool.
The problem is that we often have to suck it up using our mouths and that's really disgusting because the pool water is dirty and sometimes smelly, especially since it used to suck up the bottom.
