- Our score: 6.4 out of 10

## Verdict

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.

## Pros

- Solar powered, no outlet needed
- Mounts on ground, fence, wall or post
- Skips watering for rain and wind
- Easy app zone setup

## Cons

- Uneven watering in cup tests, 47 percent uniformity
- Strong jets can wash out bare soil
- Treatment cartridges no longer work
- Pricier than the Aiper IrriSense 2

## Specs

### Can it still dispense fertilizer?

The Smart Home Hookup reports the treatment cartridge feature was disabled after Rain Bird acquired OtO in April 2025.
