Chasing Hydro 4
Battery pool robot that can also run on a cord for long cycles
Researched by Riley Hart · updated Nov 1, 2026
TO SCORE
Is the Chasing Hydro 4 worth it? A flexible pick if you want a battery robot that can switch to corded power for long or heavy cleanings. It costs $369 as of Nov 4, 2026.
A flexible pick if you want a battery robot that can switch to corded power for long or heavy cleanings. We found no independent tests of the Hydro 4 yet, so cleaning quality is unproven, and the Amazon runtime claim of 270 minutes does not match the 210 minutes on Chasing's own store. Skip it if you want a robot with a track record from outside reviewers.
Best for: owners who want battery and corded options in one robot. Skip if: you want proven, independently tested cleaning.

Questions buyers ask
Is the Hydro 4 made by DEENO or Chasing?
Chasing makes it. Amazon listings also use the DEENO and Poolmate names, and Chasing's app was formerly called PoolmateBot.
How long does it run on battery?
Chasing's store says 3.5 hours (210 minutes). The Amazon listing title says up to 270 minutes, and we could not confirm that figure.
Can it run on a cord?
Yes, with the 2 in 1 set that adds a tether cable and power control box. Corded operation is continuous.
