In practice, the Hydro 4 excels in expansive pools (40+ ft), where its anti-resonance technology prevents pattern repetition and dead zones. The 50µm fine filter option (sold separately) elevates water clarity, rivaling cartridge-filter vacuum performance. Using the Chasing Bot App over Wi-Fi, users can schedule weekly cleanings, manually steer the robot, or initiate spot cleans from anywhere—functionality unmatched by non-connected models. However, the app occasionally lags during initial pairing, and the unit is heavier than average, making retrieval slightly cumbersome.

Pitted against the WYBOT M100, the Hydro 4 offers comparable app control with better reliability and a longer cable, though it lacks spot-cleaning autonomy. For pool owners who demand maximum automation, continuous runtime, and enterprise-level durability, this is the gold standard. Backed by a 3-year warranty, it justifies its premium status with fewer breakdowns and smarter operation—making it the best overall corded choice for those who value long-term performance over upfront savings.

Big pools demand big brains, and the WYBOT M100 rises to the challenge with smart mapping technology that learns your pool’s layout for flawless, repeatable cleaning. Designed for oversized ingrounds, this brushless motor-powered beast maintains peak suction over long durations, only pausing briefly after three-hour cycles before resuming—ideal for heavily soiled or shaded pools with constant leaf fall. Its 3-stage cleaning system combines 10x stronger suction, edge-sweeping brushes, and dual rubberized scrubbers that conform to tile, vinyl, and pebble finishes.

Field tests on 40+ ft pools show the M100 covers more ground with fewer repeats than most rivals, thanks to gyroscopic and infrared guidance that maps boundaries and obstacles in real time. The app allows full remote control, letting users draw cleaning zones, check water temperature, or trigger spot cleans on dirty steps. However, the 500W power draw may trip sensitive GFCI outlets, and the cable management can tangle in windy conditions. Still, for sheer autonomy and coverage, it outperforms many in its class.
