ECOVACS ULTRAMARINE P1 Cordless Robotic Pool Cleaner

Our take

The ECOVACS ULTRAMARINE P1 Cordless Robotic Pool Cleaner is a cordless, battery-powered robotic pool cleaner from Ecovacs. It cleans the floor, walls and waterline, navigates in a systematic pattern rather than at random, using SmartNavi IMU-based path planning, and connects to its app over Wi-Fi. A charge lasts up to 180 minutes.

On paper it scores 7.9 out of 10 (good) against other robotic cleaners. Its strongest areas are filtration (10.0) and pool size (9.8). Where it gives ground: warranty (3.0). Warranty length isn’t stated.

The best price we found is $499.99 at ECOVACS. The typical robotic cleaner we track costs $899, so this one is cheaper than most. For what it does, its value score is 8.6 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 surface skimming, the cheapest we track with it is the Beatbot Sora 70 Robotic Pool Cleaner at $1,199.

To spend less for nearly the same spec score, the Dreame Z1 Pro Cordless Robotic Pool Cleaner rates 8.7 for $399.99.

For about the same money, the Beatbot Sora 10 Robotic Pool Cleaner scores higher (8.4) at $469.

Bottom line: a good pick for pools with no outlet near the deck, scheduling and checking on cleans from your phone, large pools and buyers who want the most features per dollar.
