Honestly, I’ve tried a few window cleaners and this one was the easiest by far. It showed up with every piece in the box—no missing bits—and took me under two minutes to set up. You just snap on the machine-washable pads, plug it in, and it handles the spray and scrub for you. My windows came out totally streak-free on the first pass, and the long cord plus safety tether meant I didn’t have to keep moving a ladder. I’ve spent more on other brands that still left me wiping corners by hand, so this is worth every penny. I’m already planning to grab another one as a gift.
Not the fanciest, but gets the job done. We have second story south facing windows, and I found the best way to get rid of streaks is to run the robot once with the sprayer going, and then run it with clean, dry pads to buff away any streaks. I did need to squirt a tiny bit of water on the dry pads to help it grip the windows. Worked like a charm and got rid of the nasty buildup from running our propane fireplace every day.
