I bought Eco-jet Pro and used it 3 times so far. It does clean, but it takes longer than the 2 or 3 hours they advertise. My disappointment is the inordinate amount of time I spend cleaning the filter. Specs recommend cleaning it after every use. So far I've been spending as much as 1/2 hr. to extract dirt and particles from filter. Eco-Jet tech support confirmed that it should only be done with a water hose, which is what I am using. They don't recommend putting it in washing machine, or diswashing machine. I was more than disappointed when they asked how dirty my pool was. Their marketing brags that this product doesn't require the pool pump to be operating, We all know that a pool is dirtiest when you first open it. Although this is not even the case here. I had previously cleaned the pool with my Kreepy Krawler, but admittedly had neglected it for the past few weeks prior to using the robot. This is the only model with a Filter Cylinder as opposed to a filter bag. Supposedly it catches more particles. I don't disagree, I just find it takes too long to clean after each use. If the hose water pressure is moderately strong, all it does is move the particles further into the filter. In other words it is doing it's job too good. Filters are supposed to last the lifetime of the robot. Anyone else have a similar experience, or a better filter cleaning option for this model?
