Some constructive feedback needed please

@Zoom
It actually started as idea so I can get to bed earlier at night...then the more I thought of it, the better the concept became, and now its just a matter of implementing and getting final parts.

 

How will you stop it from creeping into a corner and staying there?

 

Been thinking about it all day and its actually possible to create movement and
sucktion with very little more noise then a hand siphon.

 

Hi @Vis

Thus far I have made 2 modifications to it.
1 Is a sort of baffle that will push hovering fry out the way and keep them from coming close to the intake.
2 Is a perimeter ring which will prevent exactly what you have raised. This will of course cause a ?sqcm area in corners not to be cleaned, but also prevent it from getting stuck.

 

You should send me your design, or mine to you. Could keep it from getting stuck in the corners but keeping the
Corners clean.
