HOBOT-298 Window Cleaning Automatic Robot with Ultrasonic Water Spray, Intelligent Cleaning, AI Smart Route Plan, Replaceable Water Tank, and Control via Smartphone or Remote

The media could not be loaded. Great machine. Works as expected. I live in a condo near Biscayne Bay with a lot of glass and this makes it very easy to keep the windows and glass terrace panels clean. I have 7 4’x10’ glass sliders and 30’ of glass terrace wall. That’s about 900 sq ft of glass counting both sides. I (or rather it) can clean all of that with very little input from me in a few hours. It’s ALMOST as simple as plug it in, stick it to the window and press go.Value: if I had someone come clean all that glass it would be over $100. If I use this device once a month, it’s paid for in six months. (I live in a bay, windows get dirty fast and often).I would eagerly recommend this to anyone who has large rectangular windows to clean. I’m sure it would work on traditional windows with mullions, too, but it would require more attention. Also would be great for store-fronts.Cons: when it does “get stuck” i don’t think it can resume from where it left off. Not a significant con. Doesn’t get stuck often.

UPDATE!! After several months, the manufacturer contacted me and offered me a $20 gift card to remove my original review below. Hmmm...You don't know how bad I wanted this product to work. Two large homes, both 3-stories, 130 panes of glass each. I've been spending $780 for each home twice a year for a pro to clean the windows.I had high hopes for this nifty product, but it just doesn't work. The technology is cool, it's simple to turn on, it stays stuck to the window and the robotics magically detect the window size and shape and direct the machine over every inch of the window. But it doesn't clean. If the window has anything other than a very light coat of dust, it just doesn't clean it, even after two passes. I used it as directed, used their cleaner product, and it's a non-starter.This cool gadget sprays a very fine micro mist ahead of its path, then sweeps the area with what is basically a micro-fiber pad. No heavy mist, no scrubbing back and forth to get the crud off. The vacuum feature suctions the machine on to your window, but doesn't "vacuum" off the dirt. If you had a foot square micro-fiber cloth mounted on a flat piece of cardboard and gently slid it over your window after an extremely light mist of Windex, you would simulate the cleaning action of this product. Try it. It just doesn't work on the inside or outside. Won't remove a light finger print on the inside or even light waterspots on the outside. Dang, I wished this worked! In ten years, we'll all be washing our house windows with a robotic product, but the technology isn't there yet.Gotta love Amazon's return policy.

The Hobot -298 works extremely well. The micro cloth really does a fine job and the unit seems well built. Its auto dispenser emits a fine spray as it works its way over the window surface. It works best on large windows. Small windows seem to confuse the sensors. Our small non opening windows are recessed into the wall significantly as that is the design the builder went with. It looks great but it seems to cramp the Hobots style a bit. On the large picture windows and on tall vertical windows such as storm doors, it works excellently. Also, for oversized bathroom mirrors it does a fine job too.I have heard the argument that a person can do a window cleaning faster than the robot, and this is true. But with the robot doing the window, you can ca doing other things at the same time. It increases productivity.Example; While the robot was cleaning the very large living room window, I was doing laundry and watching dinner on the stove. A beep alerts you to when the Robot is done or needs attention.It has not fallen off a window yet. It has battery backup should power be lost. A safety tether is included but using it is not convenient because what are you going to hook it onto? Unless you have a curtain rod above the window, there is nowhere to fasten the rope to. I took it off.I will get another unit for outside, but probably not this model. This one is pricey so a less expensive model can get dirty outside and live in the garage when not being used.

It did take me a while to figure out the process and it is important to purchase extra cleaning pads, however we have tall windows that are a pain to clean and this worked great. We do think dusting the windows first with a swiffer dry dust is the best as it keeps the pads clean longer, but this unit got the corners easier than my husband and I have been able to using a 20 foot ladder and a squeegee and towels. we used the tether but have so far not had a problem. The cleaning pads do get dirty quickly but that is because our windows on the inside were much dirtier than I realized. The windows are clean and polished. The system does give you an alert if the pads are dirty and you need to make sure you give it some room away from the side of the window to get started. The more I have used it the better it is. Yes, I'm looking at other AI items to buy, I've over 50 and I deserve to have someone or something else do the dirty work:)
