Hello everyone. We are currently in the process of building a 427 sq. ft. IGP. It will be on the smaller side (14'x35') (3.5' to 4.5' to 5.5' depth). I see a lot of folks here give rave reviews for the Dolphin 300i. I know you get what you pay for but having a hard time grasping paying $1000+ for a robot! Does anyone have any recommendations for a "quality" cleaner for my size pool, say $700 and under? We need one with a swivel cord, climbs walls up to water line, climbs steps and cleans a 6" deep tanning ledge (I heard that they won't pull in enough water for this). And hopefully will last many seasons with proper preventative maintenance. Any suggestions are greatly appreciated. Thanks in advance.
