Spec-based review: scored from Water Tech's published specifications with the same weights as every other robotic cleaner. Not a hands-on test. How we score.

Our take

The Water Tech Pool Blaster CX-1 Cordless Robotic Pool Cleaner is a cordless, battery-powered robotic pool cleaner from Water Tech. It cleans the floor, walls and waterline, navigates in a pattern its maker doesn’t describe, and has no app. A charge lasts up to 240 minutes and takes about 8 hours to refill.

On paper it scores 6.2 out of 10 (fair) against other robotic cleaners. Its strongest areas are runtime (10.0) and cleaning coverage (9.0). Where it gives ground: app & connectivity (2.0) and navigation (4.0). The maker doesn’t say how it navigates.

The best price we found is $499.99 at Water Tech, 50% off its $999.99 list price. The typical robotic cleaner we track costs $899, so this one is cheaper than most. For what it does, its value score is 7.0 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 WYBOT C1 Cordless Robotic Pool Cleaner (2026 Upgrade) rates 7.8 for $399.99.

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

Bottom line: a fair pick for pools with no outlet near the deck and buyers who want the most features per dollar.
