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.
The QC is Hayward's TigerShark with a 90-minute Quick Clean added to the four-hour cycle, but most owner reports name only the TigerShark, and many concern older units. The praise is for staying power: one QC owner calls it very reliable, one owner wore out a first TigerShark over about ten years and bought a second, another was in a ninth year of TigerShark use in 2025, and one found an older unit set out with the trash in 2024 that still ran when plugged in.
Two owners rate the cleaning well, though one finds the corded unit a hassle to haul out and set up. The cord still tangled in 2023 for an owner who flipped the handle as the manual says, and a 2026 owner says theirs lets some debris escape through the bottom flap. Failures turn up too: a year-old unit was shedding pieces and scratching year-old plaster in 2025, and in 2026 two QC owners described units that had stopped climbing walls.
It suits owners who want a corded robot they can keep repairing: one says parts are easy to get, and another went back to an old TigerShark, rebuilt with new parts, after hating the Aiper Scuba bought to replace it. A 2026 owner plans to keep theirs and add a cordless robot for cleaning every few days. Hayward's warranty covers parts for one year, with no labour.
Some last around a decade: one owner had worn out a first unit over about ten years by 2024, and another was in a ninth year of TigerShark use in 2025. An AquaVac 650 owner also passes on a Hayward repair technician's claim of no TigerShark repairs in twelve years, while allowing it may be an exaggeration. Others fade sooner: one owner's unit was shedding pieces at a year old in 2025, and a 4.5-year-old, never-serviced one had started struggling up the walls at times in 2026.
Not for one owner of an inherited TigerShark, who switched the handle orientation before every run as the manual says and still had to untangle the cord after each use in 2023. The other suggestion offered was laying the cord out in hot sun to straighten it, which gave one person who tried it mixed results.
Two owners say so: one said in 2024 that parts are easy to get, and another reported in 2026 that an old TigerShark rebuilt with new parts after its plastic broke was working perfectly. For an older unit that sticks or turns in circles, one person's 2024 advice was to replace the worn bearings and the tracks they chew up, putting tracks at about $25 a side and the swap at an hour or less with Torx bits.
Two QC owners with this problem in 2026 had already cleaned or replaced the filters, one had fitted new treads, and one saw nothing blocking the impeller. The suggestions were to run it without filters to see whether it climbs, to check the impeller for breakage or hair, and to feel for weak suction at the inlet, since a fading pump motor may need replacing.
