Solar Pool Skimmer

Our intelligent Solar Pool Skimmer simultaneously cleans and dispenses chemicals — without batteries or wires.

Just add pool chemicals to the robotic skimmer's reservoir and it distributes them as it swims.

And since this surface skimmer runs on sunlight you can let it work all day for free.

• Cleans and dispenses chemicals simultaneously

• Saves up to 66% of pool electricity costs

• Allows for the use of 33% less chlorine
