Dyson Hoover

[Thuggerz]

Hi, does anyone think a dyson hoover would be good for removing water when doing water changes?

 

[carrera]

sounds insane. let me know how it goes

 

[dgwebster]

as long as its a wet/dry vac then go fr it (ie like a carpet shampoo machine)

 

[clunkster]

as dgwebster has stated only if it is a wet and dry vac if not then dont think water and electrics

I would try it on a bucket of water first, I'd be afraid with that power one wrong move and it would remove more than the water.

Dyson don't make a wet & dry machine so no, Absolutely not

they look like they can handle water, but they cant. just because it has a clear canister that holds all the junk doesnt mean it can hold water

I'm not sure that the OP wanted to put his vacuum in the tank, but maybe wanted to use the concept of the cyclone air/solids separator (the basis of the dyson cleaner) to return clear water and separate out solids. The design of the cyclone would be very very tricky since the air/solids separator works so well because the denisities of air and solids is very large, around 3 orders of magnitude. For example, air is about 1.2 kg/m^3, whereas water is 1000 kg/m^3. Silicate sand is around 2500 kg/m^3.

That difference of 2.5ish between water is sand means that a very, very large cyclone would be needed to separate the two. And secondly, all the solids in the tank have difference densities. Making a cyclone that would only take out fish wastes, but leave the sand alone I'm guessing would be impractical to impossible.
