I like my Discovery so much I had to talk more about him.
I've been holding out for a great robot for a long time. My Pentair Legend pressure cleaner did an OK job the first few years. But, admittedly, we have LOT of trees and asked a lot of it. It started acting up, getting stuck a lot, falling over, going in circles, etc. I messed with it some and it got better but not for long. Then one day last fall it annoyed me one time too many and got some algae inside it so it got tossed into the yard. Then it got hailed on this spring. Poor fella! So, I went all fall, winter, spring and summer with no pool cleanere. I brushed weekly most weeks and definitely every two weeks and scooped leaves regularly as usual. It went OK with no cleaner. More work but less annoyance fiddling with the cleaner.
So, I've been reading all the robot threads with interest. But not wanting to spend 800, 1000 or more bucks on a cleaner. And I wanted an easy to clean top load large basket and it had to brush my pool for me cuz I'm busy and a little lazy, especially when it is pool time. Then along came the Doheny Discovery, basically the same as the Maytronics S200. And it went on sale for 650 bucks. Sold!
I've had it for a week or so. I have mostly run it every other day on its 2 hour cycle. I love it. The pool is visibly cleaner. The basket is very easy to clean, it really takes less than 30 seconds to hose it out even when it is jammed full of junk. Today it did a great job of cleaning up after some storms and a cold front blew through and dumped a bunch of leaves and tree junk on the solar cover which was then dumped in the pool. I really thought I would need to run two cycles to clean the pool. Nope, all clean after one cycle.
His name is Gilligan. It is very handy not to be the only pool boy around here!
