OtO Smart Sprinkler
Solar hose sprinkler that aims water at zones you draw in an app
Researched by Riley Hart · updated Nov 2, 2026
Is the OtO Smart Sprinkler worth it? OtO is the one mapped sprinkler that can run on solar and mount on a fence or deck, which suits yards with no outdoor outlet. It costs $589 as of Nov 4, 2026, and Bob Vila scored it 3.5/5.
OtO is the one mapped sprinkler that can run on solar and mount on a fence or deck, which suits yards with no outdoor outlet. In The Smart Home Hookup's cup tests it watered very unevenly, so if you have power near the tap the Aiper IrriSense 2 tested better for less money.
Best for: yards with no outlet near the tap. Skip if: you want even, lawn wide coverage.

- The Smart Home Hookup
- A month of testing in southern Ohio: easy setup, ran daily at 6 a.m. in hot weather and skipped watering during a rainy week.
- Bob Vila · 3.5/5
- Several weeks in a Colorado yard: brown patches improved but some remained, plants survived a vacation, and spray at long range could displace soil.
- Freshly Charged
