Oto Smart Sprinkler Review: Solar-Powered Standalone Irrigation

The Oto Smart Sprinkler eliminates the need for a power cord by using a top-mounted 2.2-watt solar panel to charge its internal 5,400-mAh battery, requiring at least three hours of direct sunlight daily. Measuring 16 x 12 x 4 inches and weighing 6 pounds, it can be placed on the ground, mounted to a hardscape or fence with an included metal bracket, or used without the bracket. The device throws water up to 40 feet in a 360-degree radius, covering up to 5,000 square feet. It connects to a standard garden hose via a side connector and requires a 2.4-GHz Wi-Fi connection for app-based control. The app allows users to define zones (spot, line, or area) and set schedules with options for watering days, start times, and weekly limits in inches. Weather intelligence can skip watering based on rainfall or high winds. The sprinkler covers the lawn by moving in circular arcs, increasing range with each swipe, followed by clean-up runs. A manual switch on top can speed up a pending run. The Oto costs $499, competing with Aiper's IrriSense 2. The reviewer found no dry patches during testing and never needed to recharge via cable.
