WINBOT MINI2 Window Cleaning Robot, Robot Window Cleaner with 5 Smart Cleaning Modes, Win-SLAM 4.0 Navigation, Automatic Glass Cleaner for Windows, Mirrors & Glass Doors

At first, I was skeptical that this robot can do a good job, but it proved me wrong. It's very easy to use and comes with everything you will need to get started, even there cleaning solution. It sticks to the window using air suction, which is strong. First, it checks the edges of the window and after that starts cleaning. I used in ok my rectangular windows and even large arch window above main entry door without any issues. It cleaned the glass well and covered everything, including edges. Bluetooth works just fine and robot announces it's actions in loud enough messages. It did get stuck in one spot where I have stopper attached to the glass, buy it continued cleaning in it's own. Love this robot, especially for large hard to reach glass.

I bought this to clean the outsides of second story windows--but it's so easy and efficient I use it on all my windows. There's no spray bottles, no squeegee, no drip or mess to clean up. TIP: Keep 1 paper towel on hand to polish the area under the robot when it finishes. That's it. TIP: Occasionally the robot gets confused and finishes and stops in the wrong place--out of reach. But I simply unplug the electric cord, and the robot slowly releases suction, allowing me to use the tether to pull it gently toward me. The tether system works well to keep you and the robot safe. TIP: The robot sometimes gets hung up on my side sliding latches. I played around and found that if I left them open, the bot correctly detected them and cleaned around them.

The Mini 2 did a good job on my very dirty windows, especially the edges. It coped with a couple of irregularly shaped and narrow windows. But my Android app doesn't keep me in touch with the Mini 2. I expected that anything with an app would let you leave the room and beep you when it needs attention. But this app is mostly just a remote control, for several reasons. It disconnects when you're out of the limited 5 meter Bluetooth range (sorry, no wifi like some expensive models have), and sometimes when the phone is off or viewing another app. It doesn't automatically reconnect when you get back in range. And it only gives notifications for serious errors, but not for "Cleaning completed" or "Out of liquid." It does flash messages on the screen, if you happen to be watching. And the bot's voice speaks up, but it's hard to hear over the suction sound, especially if you're on the other side of the window. (On my Android, notifications just don't work; it only displays messages silently in the app. I'm awaiting a resolution from customer support.) The Mini manual says it won't work on irregular shaped windows, but it worked on several of mine, none of which are curved. See my video of an irregular window with one end too narrow for the bot. Note the edge cleaning. The sprayers stopped working after a couple of sliding doors. If this happens, under Settings / Auto Spray in the app there's a handy list of things to try. I had to go through all of them to get it working again. After that one time, they only needed a Q-Tip cleaning when they stopped. But they do stop spraying fairly often, when fluid pools in the socket. And it can't detect that - you won't know unless you're watching. Stay vigilant and keep Q-Tips handy. And when the cleaning fluid tank is empty, it doesn't pause, just keeps on cleaning with a pad that's drying out. I've also seen it complain about an empty tank when it wasn't. Ecovacs advises that the Mini manual works for the Mini 2. I didn't find a Mini 2 manual online (except in Icelandic). If you find the Mini 2 too chatty, turn on Simplified Mode in the Voice Report settings in the app. The toggle flips the mode but confusingly shows off the next time the app is opened, even though the setting stays. The app should notify the user when a firmware update is available. I only found out by poking Upgrade in Settings. And the setting should be called Firmware Update. "Upgrade" sounds like an ad. When the Winbot is on an outside sliding door or window, you may need to move the door or window after sticking the bot on, but before it starts cleaning. The bot doesn't wait for you - it announces and off it goes. So you've got to push the button to pause it - and you've got to time it right. It says "The Winbot is firmly attached," Pushing the button at this point does nothing. Then it says "Starting deep cleaning," and off it goes. So when you hear it begin to say that, push fast. The safety cord and its instructions are mystifying. My ten year old Winbot W730 has a sturdy elastic bungee cord that can be tied to the power cord when needed, which is only when the bot is high above the ground or floor, usually outdoors. That's the right way. Nevertheless, the Mini 2's voice instructions repeatedly demand the cord be used all the time, and the manual illustration shows it tied uselessly to an indoor table leg. The cord is thin and has very little give, so if it does fall whatever it's tied to will get the full force of the drop all at once. And it's permanently attached, so when it's not needed it can catch on things or get in the way. I keep it rolled up and attached to the power cord close to the unit. My Mini 2 got hung up on a couple of windows with a mini-blind mount that kept it from getting completely into one corner. It could just have kept going, but it decided it was stuck and stopped. I've seen it handle a couple of other obstacles, and I documented this one for Ecovacs, so I hope they'll fix it in a later update. So, in summary: A good window cleaner, although not good about communicating with its owner.

This window cleaning robot makes keeping glass spotless incredibly easy and hands-free. Its compact design allows it to reach tight corners and smaller windows with no problem. The cleaning performance is impressive, leaving windows clear and streak-free. It feels safe and reliable with strong suction and built-in protection features. Setup is simple, and once it’s running, it saves a ton of time and effort. Overall, it’s a smart and convenient solution for maintaining clean windows without the hassle.

At 71 years of age, I'm not as comfortable as I used to be standing on a 25 foot extension ladder and juggling cleaning supplies. We live in the mountains and so dirt, dust, and pine tree pollen accumulate on our windows in a very short time. After reading some online reviews, we decided to try the Winbot Mini2. Wow! I am impressed! The robot isn't perfect - it doesn't quite reach the window corners and, occasionally, it leaves a very faint smear - BUT it does a better job than the professional and expensive window cleaning crew that we tried one time! This tool is easy to use, I can clean our upper story windows from inside instead if using a ladder, and it is convenient enough to use that our windows will be washed more often. The additional features that the free app enables is a good bonus. We are very pleased with this tool and the price seems very much worth it.

See my original review below...the product worked great, until it didn't...failed (sprayer) after just 2 days. I may have just purchased a lemon, so I'm still giving it a 3 star-rating, instead of my original 5-star. One of my least favorite home maintenance tasks is cleaning the windows. This robot takes care of 95% of the job with, literally, the push of ONE button. The robot is compact enough to handle nearly all the windows in my home. After pairing it to your phone, you simply press the cleaning algorithm you want to use (e.g. "quick clean", "Deep Clean", etc.). The setting is retained in the robot's memory, and you never need to use the phone again unless you want to change the cleaning setting. To start the cleaning process, you press ONE button, the robot adheres to the glass and then does its job. For Deep-Cleaning it takes about 3 minutes for a larger window. One nice feature is that if you have very long and high windows, if you start the robot at the bottom, the robot will conclude the cleaning cycle in exactly the same spot it started eliminating the need for a lot of ladder work. The suction is strong. The robot comes with two cleaning mops, which I was able to rotate once one got dirty (the more frequently you change a soiled mop, the less streaking you will have). I had virtually ZERO streaking and would replace the mop after cleaning about 6 lightly soiled interior windows and 2-3 heavily soiled exterior windows. Simply rinse the mop out and it is ready to reuse. For large windows I'd would have to spend about 10 seconds wiping the corners to make the window finish flawless. Also, if the windows were particularly dirty, I would recommend a quick spray-and-wipe with Windex prior to using the robot in order to get a flawless finish.

Wasn’t sure how this would work but it’s been pretty impressive. Sticks to the window and moves around by itself and is a lot cleaner than when I would do it by hand. Setup was pretty simple and the app gives you enough information on how to monitor and control it. The suction was firm the entire time and never felt like it was gonna drop. It’s definitely on the noisier side but that’s expected for something suctioning to a vertical surface. Worth the price for sure if you like keep windows clean!

It didn’t clean the windows. It didn’t cover the whole window. I tried it three times, then sent it back. I would not recommend this product.
