1/4 HP vs 1/3 HP vs 1/6 HP pool cover pump: 1/4 HP is the sweet spot for flat covers
A 1/4 HP pump clears flat covers fast enough without overkill, while 1/6 HP is too slow for anything but tiny pools. A 1/3 HP works if you need more speed or a longer hose, but 1 HP is way too big for covers that barely hold an inch of water. Match the pump to your hose length and usage — 1/4 HP handles heavy rain or all-season use just fine.
