Polaris 9550 Sport Robotic Pool Cleaner

Our take

The Polaris 9550 Sport Robotic Pool Cleaner is a corded robotic pool cleaner from Polaris. It cleans the floor, walls and waterline, navigates in a systematic pattern rather than at random, using ActivMotion Sensor, and comes with a remote but no app. Its cable is 70 ft long.

On paper it scores 7.1 out of 10 (good) against other robotic cleaners. Its strongest areas are pool size (10.0) and cleaning coverage (8.5). Where it gives ground: app & connectivity (4.0) and ease of use (4.5). Corded: the floating cable can tangle and needs the occasional untwist.

The best price we found is $1,005.92 at Home Depot. The typical robotic cleaner we track costs $899, so this one is pricier than most. For what it does, its value score is 4.3 out of 10.

If you want mapping navigation, the cheapest we track with it is the Dreame Z1 Cordless Robotic Pool Cleaner at $349.99.

If you want a Wi-Fi app, the cheapest we track with it is the Dreame Z1 Pro Cordless Robotic Pool Cleaner at $399.99.

To spend less for nearly the same spec score, the Beatbot AquaSense 2 Robotic Pool Cleaner rates 9.0 for $799.

For about the same money, the Beatbot AquaSense Robotic Pool Cleaner scores higher (8.7) at $799.

Bottom line: a good pick for large pools.
