Shiny!

[This review was collected as part of a promotion.] Easy way to get sparkling clean windows. Comes with a concentrated solution and spray bottle/cleaning pad combo. The vacuum squeegee is cordless, which makes it nice and portable! This window cleaning kit left my windows shiny.

Easy to use!

[This review was collected as part of a promotion.] Directions were easy to follow! Product worked so well!! The vacuum portion was a lot quieter than i expected, so I was happy with that!! I found it worked better when you spray some of the solution, loosen it up with the microfiber and then spray more of the solution and use the squeegee vacuum bit! It’s lightweight and easy to manipulate! It’s easy to clean and pull apart and put back together! I’m happy with this!!

So useful!

[This review was collected as part of a promotion.] This window vac is wonderful. My back window in my car gets so dirty and a car wash can only do so much. This window vac removed all the gunk and filth and left my back window sparkling! It’s so easy to use and holds a good charge. It’s durable and I love that it can be used on your car, shower, windows, etc. easy to store and clean too!

Impressive window helper!

[This review was collected as part of a promotion.] This is quite a useful little device and system! After I watched a quick video on how to start, I was soon cleaning my first windows. You do a quick swipe of the spray bottle filled with solution and attached cleaning cloth, followed by the squeegee vacuum. I was super impressed with how the finished windows came out dry and beautifully clear! I actually am looking forward to cleaning more!

Great little system!

[This review was collected as part of a promotion.] Overall this is a great little cleaning system. It makes a task no one likes to do and makes it a breeze. It’s easy to take from room to room doing windows and mirrors and is quiet enough to use any time of day, such as early mornings when the rest of the household is sleeping. The instructions for use are clear and within the first window or two, you have the usage down to a science. I’d love to see a system that is all in one, which is why I would rate this 4/5 stars - this would allow for ultimate convenience and portability.

It's ok

[This review was collected as part of a promotion.] I wasn't super impressed with this setup. It is 2 separate pieces. It has a spray bottle with cloth attachment and the other piece is a squegee with a vacuum. The squegee is loud and leaves behind streaks. Id rather use a cleaner and paper towel for the windows and doors.

Window cleaner

[This review was collected as part of a promotion.] Honestly so much more complicated than it needed to be. I diluted the concentrate and added it to the spray bottle. Sprayed down the shower door. Than had to go back with the squeegee vacuum and suck up the spray. It did not get all the soap scum but did make it slightly better. I will have to go back over with a second bathroom cleaner. I would say this is really only good for windows.

Not The Best

[This review was collected as part of a promotion.] This product was a miss for me for a few reasons. To start, the microfiber pad for the spray contraption was missing so I tested the product with just a regular microfiber towel. Mixing the concentrate into the spray bottle is just a messy process. You have the concentrate dripping down the sides of that bottle and then while filling the spray bottle bubbles foam up and spill down the sides of that. The rechargeable feature on the squeegee is nice but the cord fits very loosely into the charging port. The ergonomics of the product is nice. It does clean windows effectively. It is just a lot of work and mess for cleaning a window.

It works but takes more time

[This review was collected as part of a promotion.] I received this window vacuum complimentary in exchange for my honest review. I was genuinely torn about this one. It had worked pretty well, but I feel like it doesn’t accomplish anything that I wasn’t able to do without it before. Neither it feels like it makes the cleaning easier or faster compared to using a normal squeegee. I enjoyed using it (it’s easy to hold and use) but it made me equally frustrated. The main point of frustration was that before I made it to the right side of the window or glass door, the water with the cleaning solution all dried up, so then I had to make the other side of the window wet again to be able to vacuum that part. But because of that interruption, it seemed to cause smudged lines in the middle part. So then I had to make the middle wet again a bit to fix that and a 5 minute task turned into a 20 minute task. Also when cleaning windows with a windowsill, I wasn’t able to use the vacuum all the way to the bottom of the window because per instructions the vacuum needs to be used at a certain angle to avoid streaks and the window sill prevented me from either keeping the angle or going all the way down, causing more streaks or smudges at the bottom. So then I had to make the bottom wet again, and you get the idea now.. On a positive note, it’s pretty quiet, it was easy to assemble and easy to use overall if you’re okay with having some smudges on the glass and then getting them out with a glass cloth. After cleaning is done, it needs to be disassembled to be cleaned, and I don’t know why, but to get the squeegee off the vacuum you need to press this button with a screwdriver. I don’t understand why they didn’t make it a regular button? It seems like too much hassle. Unfortunately, I wouldn’t recommend this product.
