The product I never thought I would need!

I absolutely love this thing! The tech is intuitive and honestly works amazing. The device actually listens to your boundaries and the accurate shot that it has on the plants is amazing. I have only tried the lawn care subscription so far but the mosquito and tick might be next ! Love this thing do not hesitate purchase it ASAP!

Love the new design

This is the second unit I have added to my yard. OtO has upgraded their design with a new optional external power feature and easily accessible pair button. I really can’t say enough things about OtO. Thanks for keeping my grass green and healthy.

Amazing innovation and great service

Works like magic. I have two units one in the backyard and the other in the front. Great product and service

Had it setup in 30 min. Half that time was setting up the watering zone. It works great, charges off the solar panel and has more than enough battery to water the lawn at 6am and recharge throughout the day. I plan to buy another one for the front yard.

Innovative and eco friendly

Between the eco friendly lawn fertilizer (kid and pet safe) and powered by solar panels, OtO is one innovative, powerfully small smart device. I like that OtO knows when it’s the right time to water the lawn adapting to local conditions. Plus, their customer service is top notch!

Simple, Innovative, Delightful, and Sustainable!

In a sea of clunky, manual, wasteful, and expensive sprinkler systems, OtO is truly a game changer. After being quoted several thousand dollars for an in-ground irrigation system and wasting many hours a week watering manually, I decided to deploy 2 OtO units on my lawn. The attention to detail on this product is unmatched...

Very easy. Very happy.

I ordered an Oto to water a living retaining wall and the lawn in front of it. It took about 15 minutes from unboxing to watering. Crazy fast. I installed a drip irrigation system for the rest of my property and it's taken days. Thank you very much Oto.

how much money can I save using OtO?

A lot. Professional irrigation systems not only require major invasive surgery on your yard, it can also cost thousands of dollars up-front plus costly maintenance fees afterwards. OtO is also less expensive and needs a lot less effort than DIY-ing it. Because OtO waters exactly the right amount, exactly where you want it, you'll also save on your water bill.

got questions? we’ve got answers.

How many do I need for my yard?

This depends on how large your yard is, and what landscaping features you have to water around.

Based on a flow rate of 5.6 GPM (gallons per minute) AND a water pressure of 50 PSI, in the majority of cases, each device will 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.

When are you shipping?

Orders with devices will ship in 5-7 business days.

Orders with only solutions will ship in 3-5 business days.

How does the solution plan work?

You can subscribe to any of our solution plans:

- Lawn Food+ Fertilizer

- Stop the Bites! Mosquito Control

- Odor Eliminator

Each plan runs from March to September. Meaning you'll only receive up to three bottles each growing season, per plan.

Shipping is always free, and right now when you pair a solution plan with an OtO unit, you'll receive $100 off your device! We know you'll love it, but know you can cancel your plan at any time through the customer portal. No calling Customer Service necessary.

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.

What do I need for OtO?

All you need in order to use OtO:

1. Pressurized water (min. 50 PSI)

2. Hose

3. Wi-Fi

If you are using the solar panel, you will also need a minimum of 3 hours of direct sunlight per day. Alternatively, if you aren't blessed with this much sun, you can choose to use the included wall power adapter.

You can use OtO as a water sprinkler only, it does not require the OtO solutions to operate.
