## Product: Dolphin Sigma Pool Cleaner (2024)
**Brand:** Dolphin

The Dolphin Sigma Robotic Pool Cleaner does a pretty solid job when it comes to cleaning pool walls and waterlines. It doesn't have the fancy memory like some home vacuums, but it still gets the job done because of its SmartNav 3.0 software and gyroscope.

This tech combo helps it figure out the best cleaning path every time it's in action, adapting to your pool's shape and size without needing to remember past sessions. Based on the manufacturer's description and our research, it kind of sorts out the route each time you turn it on, so it's not cleaning the same spot in a single session, though it won't remember this for the next run.

What stands out from our findings is how well the Sigma navigates tricky pool designs. The gyroscopic tech gives it precise control, so it can scrub floors, climb walls, and clean along the waterline effectively. This ensures it touches all the surfaces it needs to, keeping your pool looking neat.

Just keep in mind, without storing maps, its cleaning can sometimes seem a bit random like traditional pool cleaners. If you cut the cleaning cycle short, it might miss some spots. But if you let it run a bit longer, it'll usually go back over any missed areas, according to our research.

So, all in all, the Dolphin Sigma is pretty reliable for cleaning pool walls and waterlines. It uses smart navigation and strong scrubbing to make sure it gives your pool a thorough clean, even if it has to figure things out on the fly each time it runs.
