X5 Robot

I have 1,200 sq ft (111 sq ms) of dual-pane glass with the inside surface covered with 3M SunPro PR-40. Of this, 800sq ft reaches 18' above floor level. This makes cleaning the window glass very problematic inside, much less outside, which I've never attempted and this is done only every 2-4 years by the home owners' association. I was skeptical that a robot could clean glass effectively without streaking, much less cling to a vertical surface while doing the job. This robot looks like an electric floor polisher (two rotating pads) without the long handle. It has a powerful motor that creates enough vacuum that it clings securely to the glass from one pad which rotates letting the 2nd spinning pad do the cleaning. The role of each pad gets reversed so any dirt is evenly collected by both pads.. Surprisingly, I really like the fact that it operates off line voltage and must be plugged in with an electric cord in order to function. No more waiting for recharging to be finished! You can use this device continuously all day and it continues to do a thorough job without a break. The only "cons" are: 1. The instruction manual is badly organized which makes it incoherent even if the English were intelligible (which much of it is not!). 2. The robot is fairly noisy but this is a small price to pay for the excellent job that it does.

This is an amazing product! I could never reach some of my 2-story windows to clean them before until now. The only reason I didn't give 5 stars is because it doesn't clean 100% of the window like you could by hand, but it's pretty close!! Also, one of the plastic rings broke immediately but I just duct taped it back together and it still works.

I initially bought the X5. Has an iphone app. I prefer it for indoors. Light and long cord. Then I bought an HCR-09 which is bulkier, but has an auto spray function which was better on outdoor buggy windows. No iphone app for the HCR (though the pads are interchangeable. Easy to use outdoors with a portible 110 supply as it draws only 50 watts.) Buy extra pads. You will go through a lot on initial cleaning. Amazing how much grime is on 'clean' windows. It is slow, especially when you do 2 or three passes with clean pads each time for the first cleaning. At this price, I ended up buying 2 X5 and 2 HCR-09. The systems are slow, and do require some monitoring. They will sometimes get confused and lock in place, and need a slight move command from the remote to get back on track. I ended up removing the safety lanyards. Extra weight, and they just dont fall. In fact, on large glass doors like a shower, they are smart enough to detect they are at the edge, and reverse course. We have 15 foot window walls and 10 foot sliding glass doors. Getting 4 was worth it. I can do an entire room inside and out in an hour or 2. With one unit, and the multiple passes with clean pads it takes to get a window really polished clean, takes a good part of a day. That would be fine if it was 100% autonomous, but as I mentioned, it will stop (still happily stuck to the glass) every 15-20 minutes, and needs you to use the remote to move it away from an edge that confused it. One other little discovery we made. Glass is actually somewhat 'porous' enough for the suction system to work. We have a shower with a 12 foot long by 10 foot high window wall. We had used rainX on it to stop water stains, even with softened water. RainX makes the glass too slippery for the device to climb, and needs to be removed for the 'window worm' to do its thing. One thing that would be neet was if there were some kind of pole system or such where I could attach the critter up high, and then get it back down. We have windows whose bottoms are 12 feet up, and I need to use a ladder to climb up to stick it on to do those windows. Not sure how they might do that, but it would be slick. Also a bit baffled why these otherwise clever chinese companies cannot hire a native english speaker to proof the documentation. Its adequate, but you got to wonder 'Please place the sine on the area beneathed your device so in the evented fall, no one transitting the earth be injurred.' I am paraphrasing.... Great product. Will easily pay for itself in saved third party cleaning fees. And with the 4 units, I can do the whole house monthly, instead of the quarterly I pay a window cleaning service. Stunning how clear a polished window is, versus guys with soap and a squeegee

Bought this robot with lots of hesitation because of the reviews. Here to say I’m so happy to choose to try it. it’s awesome. Ignore the negative comments. I recently installed a new window that I can’t reach to clean. This works perfect. Few tricks 1) wash window with wet pads (just one to two sprays of cleaner 2) wash a second time with dry pads you may have to run it twice on dry to remove swirl marks from the pad. I did not but I could see how that may happen. It takes a bit to get it perfect but when I do the windows with a squeegee it takes me one to two passes. At least with this you can walk away and do something else. One review said best Amazon purchase I might have to agree. I bought the not spray version based on customer feedback and also agree the built in spray is not needed I would skip and save a bit of money.

This did not work AT ALL. My windows were dirty (water spots) after having the house power washed. This just served to smears the water spots around some. Maybe the version with the sprayer would work, but this version doesn't even come close to getting the windows clean. I don't know if you can tell in the picture, but the water spots are just smeared around after 2 passes with the robot. It is also quite loud, so not very pleasant to use for that reason.

So this cleaner does have spinning pads that go across your window. It comes with a remote, but also connects to your phone with an app. The robot itself doesn't have any way to apply cleaner. An empty spray bottle comes in the box, and it says liquids can't be shipped back from China. OK but they could at least give you a cleaner formula to make. Instructions tell you to spray one or two squirts of "cleaner" on the bottom pad. I can tell you for a big window, one or two squirts does nothing. Wet it too much and the robot doesn't move. So you basically have to keep the pads dry, but wet the window. Works OK, not great. It can smear a-lot, and your windows need to be pretty clean before starting, but if they are, why use this robot to clean them? I'd call it better than nothing, but not great.

El robot funciona correctamente conforme a sus indicaciones, lo probé en un tercer piso en ventanas internas y externas con la seguridad mencionada, los cristales quedaron muy bien. Adicionalmente utilicé un poco de limpiador para cristales con amoniaco incluido.

And the seller won’t respond.

I don't know what the problem is, but after the third wash, the window cleaner has no power to hold onto the glass and not enough power to go up.

Me encantó este producto! Es muy bueno.

Kept falling off because the power cable is too short. And why are u shipping this with a type C wall connector? The moment it loses power its a Hazard.
