Decision guide
How to choose for this pool need
Continuous power changes the routine
A corded cleaner can repeat or extend cycles without waiting for a battery, which suits heavy debris and long cleaning windows. The trade-off is safe cable routing, storage and keeping swimmers away during operation.
Confirm the exact Hydro 4 variant
The Hydro 4 page offers corded and cordless selections with different power and handling routines. Confirm the SKU, cable or battery equipment, and tracking destination rather than assuming one review describes both packages.

Common questions
Before you make the shortlist
Is a corded robotic pool cleaner better than cordless?
Corded is better for continuous or repeated cleaning; cordless is better when removing deck-side cable management makes routine use easier. Pool size and cleaning pattern decide which advantage matters.
Can you swim while a corded pool robot is running?
Keep swimmers out while any robotic cleaner operates and follow the model manual. Electrical equipment, moving cables and an unattended machine should not share the pool with swimmers.
