Oto Smart Sprinkler Review (2026): Solar Powered and Easy to Use

Once configured, the setup continues as Aiper is pricier Irrigreen software: You create a zone, then use the software to define its boundaries. Similar to the systems mentioned above, the Oto sprinkler is designed for efficient irrigation, shooting water into the tree in one direction instead of a large spray. That said, Oto’s spray is narrower, hitting only one patch instead of creating a two-way water curtain like Irrigreen’s “water seal system.” You get a good idea of ​​this when you set the boundaries of your yard.

Like its competitors, Oto allows you to set each region as an area (for watering a single tree, perhaps), a line (for a garden), or a 2-D area (for a yard). I tried all these types but I spent most of my time working with layers, which is very difficult. When explaining the circuit, I found that the Oto system is similar to Irrigreen and Aiper, although it is slower to respond to commands. Even so, it’s easy to use: The simple interface allows you to drop points around the sprinkler to define the boundaries of the area. When you make a complete circle around the sprinkler, the area is finished.

When editing, you can set the schedule for each section, with many options available for the days to finish (odd days, even days, select days of the week, every day), and choose the start time (although there is no time to connect sunset or sunrise). Each plan also has a weekly watering limit (in inches deep), which you will divide by weekly watering. Smart weather tools let you choose to skip watering if your zip code receives measured rain or high winds (both based on online reports); the user can control the amount of rain and wind speed to trigger the jump. The app keeps track of the 20 most recent events and has a calendar that details upcoming events.

When watering, Oto takes a new approach to covering the grass, first moving it in a circular motion around the sprayer, then gradually increasing it with successive swipes. When it’s done, it runs a “clean” run again to hit any areas that the original water didn’t reach. The speed is slow enough and the size of the water beam is large enough that the coverage is strong. When tested, I found that the yard was very wet all over, with no dry areas.

As with sprinklers, changes in water pressure can sometimes result in over or under water in areas, but I found this to be less of a problem when using the Oto. However, when you irrigate at the Oto terminus, the force required to throw the water far away can cause a strong explosion, which can cause soil erosion or damage to the damaged vegetation.

Oto also has a “game mode” that allows you to use the sprinkler in a water chase game or the alternative “splash tag”, aka “try to avoid getting hit by the water.” Acceptance advice: It is impossible not to be beaten.
