We have the same Hayward TigerShark that we bought when we built the pool in 2008. For the last year we have had to baby it to get it to run. I think it's an issue with the power cord connection, but hubby is not convinced it's worth fixing because of the age of the unit. Sometimes when you put it in the pool it won't start, but if you play with the cord or reverse the handles it usually will start. Reading through the forum, the concensus seems to be the robot cleaners only last 3-5 years, so I guess I should be thankful this one has only required new filters on occassion, one set of new belts and roller covers. I like that it manages the rounded corners, you can adjust how high out of the pool it comes to scrub the waterline, has a long cord, cleans steps and bench with no problems and picks up fine dust as well as leaves. So looking to replace it. Because we has such a good experience, we are considering buying another one... however perfromance of a 2008 model may not be reflective at all of 2023. So looking for anyone who has any experience with a recent purchase and which other robots should I consider?
