Which of these cleaners is the better of the two?
I have a lot of sand, but also need it to climb and scrub walls of my freeform pool.
I had a polaris sport robot previously but it only lasted 3 years and during those 3 years I replaced the main module, a wheel and now it needs a new motor.
I have heard very good things about the Dx5+s and the DX6. Do they have a bag or cartridge or both? I can't figure out the difference between them How do they compare to the polaris robot? Would you recommend one over the other?
