I have a Polaris 9300xi that is having trouble with getting stuck on my pool steps. I found a used aquabot for under $400 with a 30 day warranty. Am I crazy to consider a robot w/o warranty or would it be worth giving the aquabot a try?
I would not buy a used robot unless you can get some type of extended warranty which usually you can't with used products. The motors themselves are 250+, power supply is 200 etc. One failure and its not uncommon and you will be throwing the robot away. For 600 you can get a smartpool with 2 year warranty. You can also sometimes find refurbs and open boxes cheap on ebay that will allow purchasing an extended warranty.
