Corded waterlineHayward
Hayward's long-running TigerShark, in its QC form, adds a 90-minute Quick Clean to the standard four-hour cycle over floor, walls, coves and waterline. It runs on tracks and a cartridge filter, and Hayward's warranty covers parts for one year with no labour.

A specification not listed here is one Hayward does not publish for this model. It is left blank rather than estimated or borrowed from a sibling.
The two lists above come from the maker’s own specifications and this site’s arithmetic on them, not from owner reports. Where owner discussion has been read it appears in its own section below, so the two are never mistaken for each other.
Owners talk about the TigerShark platform — which the QC is a version of, adding a 90-minute quick-clean cycle — as the durable old workhorse of pool robots. The stories are about decade-long service lives, easy parts and a repair technician who claims never to have fixed one.
The complaint is the cord, which tangles even when owners follow the manual's advice on flipping the handle. There is little discussion of its cleaning versus newer robots, which says something about where it sits: it is kept and repaired, rather than newly shopped for.
Owners who value a long-lived, repairable robot over app features are the ones it rewards. Note that Hayward's warranty on it covers parts only.
Owners report around ten years from one unit, and a repair technician quoted in one thread said he had never had to fix one.
Owners report it tangling even when the handle orientation is switched before each run as the manual advises; untangling after use is what they fall back on.
Owners say replacement parts are easy to find, which is why old TigerSharks stay in service.
