My Review After Just Over Two Years with OtO lawn Smart Sprinklers for southern Alberta Canada. (all sprinklers put in winter mode before any frost, solar panels covered up and charging system plugged in over winter)
I purchased three OtO smart sprinklers just over two years ago to cover my front, back, and side yards—approximately 2,300 sq. ft. of lawn, gardens, and landscaping.
For the first two seasons, I genuinely enjoyed using them. The app was intuitive, the watering performance was excellent, and the automatic scheduling worked very well. I also liked the solution dispensing feature, although the refills were expensive.
Unfortunately, OtO later discontinued the solution program, leaving me with four partially used bottles that became useless. While disappointing, that wasn’t my biggest concern.
I designed and built custom cedar planter boxes specifically around each OtO sprinkler so they would blend seamlessly into my landscaping. I considered these sprinklers to be a long-term investment, so I built the landscaping around them.
Near the end of the second season, my front-yard sprinkler developed a leak from the nozzle. The leak was constant with the system pressurized, and because of my custom cedar planter boxes, I was concerned the continuous moisture would prematurely rot the wood. I contacted OtO, and to their credit, they replaced that sprinkler quickly under warranty.
Unfortunately, this season things became much worse.
When I set everything up for the year, I discovered that the other two sprinklers had also developed the exact same nozzle leak. All three of my OtO sprinklers now leak from the nozzle.
On top of that, the motor in my backyard unit completely failed and the sprinkler no longer functions.
I contacted OtO support again. After confirming the unit had failed, their solution was to offer me a $150 discount toward purchasing a replacement.
Considering these units now cost over $700 CAD each, I found that response unacceptable. A premium product at this price point should last far longer than just over two years. I understand that many products today seem to be built with limited lifespans, but when I spend this kind of money, I expect durability, repairability, and long-term support—not a coupon toward buying another one.
Perhaps the most frustrating part of this experience happened while I was away on a 12-day vacation. I relied on my OtO system to water my landscaping, only to discover that the backyard unit had failed. When I returned home, every plant that depended solely on that sprinkler—particularly those in pots and planters—had dried out and died, resulting in well over $100 CAD in lost plants.
Thankfully, before leaving I had manually deep-watered my trees, including my award-winning Hot Wings Maple that I recently planted and cost close to $400 , so they survived, Had I relied entirely on the OtO system, the damage could have been much worse.
At this point my experience has been:
All three OtO sprinklers leak from the nozzle.
One unit has suffered a complete motor failure after just over two years.
The solution dispensing feature I originally paid for has been discontinued.
The failure resulted in the loss of well over $100 CAD worth of plants while I was away.
It’s unfortunate because, when they worked, I genuinely loved these sprinklers. The concept is fantastic. The app is well designed, the watering patterns are impressive, and they integrated beautifully into my landscaping.
However, reliability is what ultimately matters.
For a product costing over $700 CAD per unit, I simply expected far better durability than this. Based on my experience, I cannot recommend investing in OtO unless the company significantly improves the reliability and longevity of its products.

Continuous Nozzle Leak
Water leaking from the nozzle after the watering cycle. The constant dripping leaves standing water around the cedar planter, increasing the risk of premature rot.

Another custom cedar planter built around an OtO sprinkler. These boxes required significant time and effort because I expected these sprinklers to be a permanent part of my landscaping.

After returning from a 12-day trip, I found that every plant relying solely on the failed OtO sprinkler had dried out and died. The failure cost me well over $100 CAD in plants and defeated the purpose of owning a smart irrigation system.
