We're not a big media company. We're a small, independent team that actually gets in the water and tests this stuff.
Every robot, pump, and skimmer gets run in our test pool under real-world conditions. Not a lab. Not a demo tank. Dirt, leaves, algae — the works.
We don't review products in isolation. We test them head-to-head so you can see exactly how they stack up against the competition.
We've been testing pool products since 2020 — through every season, firmware update, and product launch. That depth of experience means we know what holds up and what doesn't.
We run each product through multiple cleaning cycles in our test pool — floors, walls, waterlines, and filtration all get evaluated.
Products go up against their direct competitors so you see real differences, not just marketing specs.
We publish what we find — good and bad. If a $500 robot beats a $2,000 one, we'll tell you.
