Would We Recommend It?

Recommended With Reservations

The Polaris ERA 820 Robotic Pool Cleaner offers a 60-foot cable with a tangle-reducing swivel, cyclonic vacuum technology for sustained suction, and a large 4-liter debris canister, which supports longer cleaning sessions. Its plug-and-play operation and included transport caddy and cover enhance convenience and durability. With 54 ratings averaging 3.5 stars, it holds a moderate reputation compared to alternatives with higher ratings and more reviews, such as the Dolphin Nautilus CC and WYBOT S2. The ERA 820 is corded and suitable for pools up to 50 feet, but lacks detailed efficiency specifications and advanced smart features found in some competitors. Pricing at $899 sits between lower-priced and higher-end models, reflecting its features and brand heritage.

Best suited for

Pool owners seeking a reliable robotic cleaner with corded power and patented cyclonic suction for mid-size inground pools up to 50 feet, who value ease of use and accessory inclusions.

What to consider

Sample size of 54 reviews is moderate but rating is average (3.5). No information on warranty or advanced smart controls is provided. Compared to alternatives, it lacks cordless operation, app control, or extended cleaning times. It may not be the best choice for very large pools or users wanting advanced navigation and scheduling. The weight (35.9 lbs) is relatively high, potentially affecting handling.

Value versus similar cleaners

At $899, the Polaris ERA 820 offers decent features and brand reliability, but moderate user ratings suggest potential limitations or mixed performance. Alternatives like the Dolphin Nautilus CC and WYBOT S2 provide better ratings and more features at a comparable or slightly higher price, so buyers should weigh feature needs and pool size when selecting.
