This does a great job. Is it perfect? No. It misses corners a bit and can leave a couple circles where it terminates. It’s not quiet. But it really does clean and it is a work horse. Couple of tips: works well with windex in the reservoir. Don’t use a soapy window solution or the robot will slide off the window. Really dirty/dusty window? Use the remote and run it multiple times A few times it seemed to stop working, tried it again the next day and it was fine. Doesn’t work well with tiny or very narrow windows. Works great on mirrors (including sliding mirrored closet doors) Doesn’t work on car windshields I think the angle is a challenge. (I’m trying it on everything!) Compared to the cost of having a service come out to do the windows this is a no brainer. If this breaks down I’ll get another and still consider it a win.

I have a second story office window with the best view in the whole building, and literally 2 months after all the windows were cleaned, a bird somehow managed to poop on my window, which is pretty impressive since it's under an overhang. Did a search and found this product and thought I'd give it shot (the office manager was on board too). Thankfully had a lower transom type window I could open and was able to get the unit placed with a little effort. It did the first pass of the whole window, and did a great job, but the poop spot needed some extra work, so it was easy to drive the unit to the spot and use the spot-clean mode about 5 times to really get it clean. Amazing technology! Great job to the engineers that put this thing together! Highly recommend! One note...I couldn't find in the manual what type of cleaning solution to use, so I just mixed 1/4 of the included bottle with window cleaner and water and it seemed to work well.

I was so excited to learn about the new generation of window washing robots. I couldn't wait to buy one. I did extensive research, comparisons, and how-to video watching. I settled on this Tosima W3. I wanted it to work so badly. But perhaps I expected too much. This device definitely requires a learning curve. I have now used it five times, in three different areas of my home, inside and out. And I have a little higher opinion of it, than I did at first. The first attempt barely completed the task, but the last assignment was flawless. Hence the learning curve. PROS: The machine is good quality, the suction is adequate, there are sufficient cleaning pads, and it does a good job of cleaning. It works best on large, unobstructed, straight windows with no window treatments. If this is all you have, it will work well for you. Because the windows look nice, once it's done. CONS: And, there are many! 1. The machine is kind of heavy, when it falls...it falls hard. And it does fall! Never leave it alone on high up windows. 2. The cleaning pads are difficult to put on and take off, especially for old arthritic fingers. 3. It is loud. I live next to a golf course, and I thought the players and/or the neighbors were going to complain about the noise, but they didn't. 4, When it falls, or gets stuck in a small space, the rotator wheels get dislodged (causing it to fall). There are no instructions on how to put them back on, or fix one that has only partially come off. 5. The remote is not easy to figure out on its face. The book is helpful tho'. 6. The spray takes a LONG TIME to work. 7. The safety rope sounds good on the surface, but realistically, its not of much use. Most of the time, there is nothing to attach it to, unless you want to put hooks in your ceiling. If you make the rope too short, it won't reach all the window. And in the event of a high up fall, I think the device could likely break any window below it, in it's first bounce or swing. But, I think this is probably an issue with just about any window robot. And two things I did not hear in any of the reviews or videos: 1. Inside mount shades or blinds may affect its ability. It will depend on how much clearance there is between the fully raised blinds or shades and the device. It is several inches think. I had one set of shades that worked, and one set of plantation shutters that did not, causing it to fall. 2. Finally, the minimum dimension of a window is twice as large as I expected. I ordered a "slim" model, because I have small windows that slide to open. It doesn't work on these windows, because it can only travel by circular motion. It can't travel straight in any direction. All in all...tho' I am still learning...I think it will work for me, in the long run. It does not actually save any time, as it's not speedy. But it does keep me off ladders, and save my arm and shoulders. Not my neck...because I still have to look up! But, pushing buttons is much easier than climbing ladders and cleaning windows, for this old lady!

This review is not so much on the product as it is on Amazon and Asurion we have had the product for 4 months and it has worked relatively well I have suggested this product be bought by dozens of people and after 4 months the product has stopped working I posted a video to show where it gets stuck in one location and does no longer move I have reset the product check the fluids check the cleaning wheels made sure it had a good connection and when contacting Amazon because it has a one-year manufacturer's warranty they refused to replace it so I contacted the insurance plan that I purchased but because it has not been a year the insurance plan also will not cover the product

This product is worth the money. It has cleaned the windows well and I haven't had any issues so far. I was considering getting a window cleaning robot that is over double the price. I'm glad I went with this one instead! My only negative is that it leaves a small circle on the window when it finishes cleaning. It's easy enough to wipe that one spot with a towel, so not a big deal to me.
