Which brand is most reliable for pool robots?

By sheer verified-purchase volume, Maytronics Dolphin dominates this pool, with the Nautilus CC and Nautilus AG carrying five-figure and four-figure review counts respectively. High volume at a solid average is a meaningful durability signal, though it is not a substitute for independent lab testing, which was not available for these candidates. Newer entrants like WYBOT, Aiper, and Beatbot post strong averages but on far smaller review bases.
