Mine is a 2019 2552 with moderate use.
I have not sleeved my Sanicon hose and don't remember seeing much (or any) discussion of sleeving on this forum.
I haven't used my unit heavily, so perhaps you'll get answers from some who have. I've been reasonably careful with the hose when I use it and in folding it back in the unit, and there have been no issues to date. The hose still appears to be in good shape.
I know there have been some previous postings here regarding hose replacement, but I don't recall cost or difficulty--I doubt either would be unreasonable. That being the case, there may be an argument for just using the Sanicon hose with some care, and replacing it if and when it does fail.
