Hi reading the rant made me chuckle any way in pets at home there is a a substrate/gravel cleaner for 5.99 and it has a bag at top and you attach it a a normal air line fix it to your air pump and plug in. As you move it around all the waste goes into the bag while the water goes straight back into tank. It is brilliant as clean up tank half way through week and no water change and even better no water in mouth It feels a bit flimsy but really worksssss
hope this helps . Sorry can not remember name of it as old girl bad memory but the handle is green if that helps

the instructions for the thing are pretty rubbish. I was lucky as my Dad had one for his tank when I was a kid so I'd seen it in use.
Great though for doing the job. Sucks up a tiny bit of sand but that's nowt to worry about
