I have had the same problems with my sea clone. I got to the point were I was fed up and went out and bought a Back Pac. That was the best thin I have ever spent money on. I love it but it is a little bit loud. You will be impressed enough you wont mind the noise and it will do such a better job. When I had the clone I thought it was pulling an ample amout of waste out but with the back pac I now no it wasn't even close to doing its job.
