Why it matters

The SP550C has a tool-free detachable base, so it works as a pool cover pump in winter and a regular submersible pump the rest of the year. SEESII rates its 1/3 HP motor at up to 3,035 GPH and 30 ft of lift.

A water level sensor starts it at 2.5 in and stops it at 0.75 in. It comes with a debris net, adapters with a built-in check valve and a 25 ft cord.

Who it's for, and who should skip it

Pros and cons

Pros

  • 2-in-1 design
  • Auto sensor
  • Debris net

Cons

  • Newer brand
  • Leaves 3/4 in
  • Thin warranty info

Limitations to weigh

  • On a pool cover, set the pump at the lowest point and keep the strainer clear of leaves.
  • Rated flow is at little or no lift; through a garden hose or up a stairwell, expect much less.
