I’ve liked to clean the room since I got Dyson Digital Slim cleaner for two years. It’s light and easy but powerful stick cleaner for everywhere. But I claimed one thing for the windowsills such as narrow rails of the windows.
I finally found a good tool for the narrow slideroads to clean. It’s ” flexible nozzle “. I bought it online and used it. I’m totally satisfied with it and get to love clean the sashes!
