Get 10% off your Sutro with code “POOLOPENING” for Pool Opening Week! Sale ends May 2.
The Sutro App sends you quick easy readings 3 times a day so you have daily knowledge of your exact pool chemistry without ever getting your hands (and arms!) wet.
No more complicated chemical calculations. The Sutro App tells you what chemicals to add to your pool, based on your choice of chemicals.
Only add the chemicals you need, when you need them. Save on wasted chemicals and avoid systemic imbalances that lead to expensive resets.
Always on standby. Sutro’s success team is available at the click of a button to solve your water problems.
No burning eyes or itching skin. Bacteria and viruses thrive in untreated water. Healthy water means healthy swimmers. The Sutro App sends you exact readings and perfect chemical recommendations so your water chemistry is always perfect.
A perfectly crystal clear pool is a matter of pride. The Sutro App provides you with the information you need so that your pool is always perfectly clean and crystal clear for you, your friends, and your family to enjoy! Guaranteed that your pool will look better than your neighbors.
Your pool on autopilot. The Sutro monitor knows when the cartridge is running out, and a new one will be at your doorstep before you know it. We tell you what to do when you do need to do it, so you can focus on the things that matter.
Your pool water is a living environment, it is continuously evolving. A healthy pool is a fine balance between a clear pool or a green pool. And if you’ve been there, you know.
Where it gets complex is we just make it super small. It takes a lot of internal complexity to make taking a water measurement a reality. We use our partner LaMotte’s reagents to ensure that we have the gold standard for water testing.
Sutro has the most advanced technology on the market, and how do we do that? Simple, we use the same reagents that's used at your pool store - a tried and trusted method for the last 100 years and is used by the EPA.
Theres a complex chain of micropumps, robotics, lead screws, and syringes that add up to give you that reading - and we take it a step further by turning that into something that you can act upon in a simple way. We take that a step further, and give you a chemical recommendation that tells you what to do and when to do it (with the chemicals you already have in your shed).
Our chemistry is done via a clear flow cell and a cartridge full of reagents. If you have ever used a liquid water test kit, then you know what we’re doing -- the same way that you take a sample of water, drop color in the cell, mix it up, and then compare colors - is the same thing we do... Only on a microscopic level. For us, micro means 1/50th the volume of water you would use in a normal test kit. It’s a simple process made complex by all the little things that could go wrong like bubbles, dirt, scratched flow cells, etc.

Never miss a reading. Get the data you need when you need it for complete control of your pool chemistry.
Sutro gets you connected very quickly. In less than 5 minutes, we’ll have your Sutro floating in your swimming pool and sending you readings. The hub & charger is base command central for all the data coming to and from the Sutro Unit in your pool (or spa). We've also packed this hub with a ton of technology,
The Sutro hub allows your monitor to always stay connected, even when under a swimming pool cover. It’s rated for a maximum of 100 yards and will power through walls

Who cares? The 900MHz makes it possible for us to send small amounts of test data without needing to have a real high transmission rate. We're not sending YouTube videos to and from the Monitor, we're sending you some water test data.
Your battery is always ready and waiting for you, the hub actually doubles as a battery charger as well as communications hub. It’s also greener, because we all know how harmful batteries are for the landfills.
Data is power. You can have your entire pool’s history at your fingertipsfinger tips so you alwaysto know how your pool is feeling
You already have a smart garage opener, or smart thermostat. It’s the last piece of your house to be connected. Sutro completes this loop with our Alexa and Google Home integrations. So knowing how much of each chemicals to add toput in your pool is just an push notification ‘ask’ away.

Sutro works with all types of water, chlorine, bromine, tablets, and liquid chlorine. If you buy it from a pool store, we’ll tell you how much of that particular chemical to put in your pool.
Sutro also works with salt water systems from all major manufacturers: Hayward, Pentair, and Zodiac. We don’t actually measure the salt in the water, but we do correlate off of the ppm (free chlorine), to tell you if your chlorine content is falling.
Hot water doesn’t bother us at all. Actually, chemistry changes in spas even quicker than in a swimming pool. It’s even more important to have a Sutro for your hot tub or spa. We work with all major brands and different types of chemicals. Bromine? Chlorine? We got both of them covered.
DE, sand, glass, cartridge, or grid. We can work with all types of filtration systems. Sutro’s goal is to make sure your water is safe to swim in.
We also work with ozone and mineral systems. So if you need to keep your chlorine content lower for your Nature2 or copper-silver systems, we got you covered
Sutro works with ALL chemicals currently that are on the market, so we don’t fix you to a particular brand. We take it a step further, and you can SCAN your chemicals into our system, and we work with the chemicals what you like.
Sutro allows the sharing of data with your pool store, and we may already work with them. With the added information from your Sutro, yourthe pool store will be able to give you even more curated, and personalized recommendations when you step in there to get your full 21-point check up.

We understand that not everyone lives in Los Angeles, Austin, or Orlando. You only pay for how many months you use your pool. 3 months in Boston or 12 months in San Diego - your choice! You only pay for subscriptions when you’re actively using your pool, and you can start and pause your subscription any time.

No more wondering or worrying about how much of chemicals to put in my pool! Loving it!
It saves me time and I never play catch up on my chemicals.
Saves me trips to get water checked and also let’s me tell my daughter who lives near by what needs to be done when I’m away, so the pool doesn’t get out of wack when I’m not there.
Every time I need ANYTHING, tech support is there. They always solve the issue quickly and sometimes before I even notice I have an issue.
It works. It keeps me on top of my pool, which I think results in less chemicals. It's easy!
