I certainly agree "cleaners are meant to keep clean pools clean". I have several cleaners. Although, my current robot, is an old Aquabot, its cleaning action/function is more like the 9300 than say a suction or pressure cleaner . When I have even more EXTREME amount of sand/silt/dust, than our normal EXTREME amounts, I sometimes have to change out the fine filter bags every hour or so because they become clogged with the fine dust. This is when the suction cleaner is the best choice.
On another note..... Some of the newer robots move faster than the older models. I found information on the site, I love my Aquabot, recommendation for types of cleaners depending on the kind and amount of debris going into a pool. The slower moving 'bots, like the original Aquabot, move much more slowly than some of the new ones, stirring up the bottom much less. The slower speed may take longer to clean the pool but hardly anything gets stirred up. 'bot with more jets action also stir up the fine debris more. I traded my Vero 300 for an old, used, reconditioned Aquabot. The main reason I traded was because the Vero 300 couldn't make the climb to the shallow end after a few minutes when the bag was beginning to clog. After using the old Aquabot I discovered that, although they moved about the same speed, the jet action of the Vero was stirring up more fine debris on the bottom.
This is why I always ask people, who are considering different cleaners, "What kind of debris and how much goes into your pool?"
