It only uses Water!!! I know right !?! I really had to put it to the test.… so I used Vaseline to create those hand prints😅 yup! So good right? It’s also on Sale! 🎉 This is THE best window cleaner I’ve used!😆… trust me, I love my window sprays but nothing beats an automatic window cleaner 😆… plus, no more climbing ladders to clean your windows…. And you only need water! 🫢 I cleaned the outside of my home and it cleans just as well! It is both automatic & remote controlled so you target specific areas you’d like to clean. It can connect to your phone as well! 🤍❤️ Plus It has intelligent detect to prevent falls. 🎉
