Saltwater has a limit
Beatbot and Aiper say their robots are fine in saltwater below 5,000 ppm. Compare that with your pool’s salt reading.
Wybot, Dolphin and MOVA don’t mention saltwater on the pages I checked, so I show “Not stated”.

Runtimes aren’t like for like
Wybot’s 3 hours is in Eco mode. Beatbot and MOVA give hours on the pool floor; Beatbot says the Sora 70 runs up to 7 hours skimming the surface.
Dolphin’s 2 hours is one cleaning cycle on a cord, not a battery.

Check it fits your pool
Aiper lists the Scuba X1 for in-ground pools, and Dolphin lists the Nautilus CC Plus for in-ground pools. Wybot gives a maximum depth of 13 ft for the C2.
MOVA’s US page doesn’t state pool type, surfaces or maximum size for the Rover X10.
