What is the OtO device?

oto is the only sprinkler and treatment device you'll ever need. By automatically watering and applying liquid treatments to your lawn and garden from one compact device, you'll significantly simplify your maintenance routine and save up to 50% on your water bill.

• Fill each unit with up to three different subscription plans.
• Control your schedule and apply on demand with the OtO Lawn App.
• Solar powered for maximum convenience.
• Each device reaches up to 30 feet in 360{degree sign}*

How far does the OtO device reach?

Based on a flow rate of 5.6 GPM (gallons per minute) AND a water pressure of 50 PSI, in the majority of cases, you will be able to reach a maximum of 30 feet.

Due to differences in water pressure regulation at each individual residence, in some cases, you may not be able to reach 30 feet.

For best results, we recommend measuring your water pressure with a water pressure guage before purchasing OtO. We also recommend only using OtO with a high-quality hose with an ID of 5/8" or greater.

How does OtO save water?

With the precision watering nozzle, you can program exactly where you'd like to water, avoiding sidewalks and driveways.

OtO's intelligent system also factors in the weather, wind conditions and water pressure, only watering in a way that maximizes absorption.

As such, over time, OtO can reduce your water consumption by approximately 50%, even saving you money (and helping the planet too!).

Does OtO account for wind?

Yes! Watering or applying lawn treatment products when it is too windy is inefficient - it increases the amount of water that is blown away in the wind or the moisture evaporates quickly before it can properly feed the plants.

As long as you have Weather Intelligence and Wind Skip enabled for your zone, OtO will not water when local windspeeds are above a threshold that you have set.
