To make use of Space mode, you first should outline the boundaries of the world. That is accomplished within the app by way of a course of much like what I’ve encountered on some competing {hardware} units. You fireplace up the mapping mode, and the sprinkler engages. Then, utilizing a easy remote-control system, you dial the water stress to the suitable stage, aiming on the fringe of your yard however not the fence; as soon as the water is the place you need it, you drop a pin to mark the boundary of the watering space. You then rotate the nozzle on high of the sprinkler a number of levels and repeat, setting the power of the stream to cowl the specified space. Repeat many times till you’ve gone by way of 360 levels and have dropped pins to visually characterize everything of your yard. The corporate says the utmost supported space is an unlimited 4,800 sq. toes, with spray reaching as much as 39 toes.

Within the app, you possibly can watch this space map being created in actual time. The method is sort of intuitive aside from the ultimate couple of factors, the place Aiper’s system makes it tough to finish the 360-degree circuit. Should you have a look at the finished map within the screenshot beneath, you’ll see a tiny sliver of yard that no quantity of finagling may get Aiper to shut up.
Watering runs might be initiated on demand or on a schedule, and also you intriguingly outline not an period of time to run however a “water consumption restrict,” measured in inches of water you need utilized to the soil. Whereas it’s almost unattainable to measure how correct that is, qualitatively, these estimates felt about proper in my testing.
In Space mode, the IrriSense 2 delivers water by spraying a jet in a single course, rotating clockwise by way of its 360 levels till it’s gone all the way in which across the map you’ve set earlier than turning again and doing it once more in a counter-clockwise course, repeating this cycle till the specified irrigation depth has been reached.
Whereas the IrriSense 2’s spray system is formally described as a mild “mist,” it’s actually extra of a jet, notably when it has to succeed in the far-away components of the yard close to the terminus of its vary. That ends in much more water being delivered to the sides of the yard than to the central portion of the mapped space, however that’s a standard problem I’ve seen with rotary sprinklers like this. To account for this, the IrriSense 2 doesn’t simply blast at full velocity for everything of its run. As a substitute, repeated rotations scale back the stress delivered little by little, till the ultimate rotations are little greater than a trickle of water hitting only a few inches away from the unit. (Notice that canceling a run early signifies that solely the outermost parts of the world will obtain water.)
