多、高层建筑擦窗困难,不论居民或单位都有这个现实问题。揩擦高层建筑窗玻璃室外一面有危险性;有些大楼房间的窗户,还装有固定玻璃窗,擦起来更困难。人们希望科技工作者重视研制这种家用小工具。 Many and high-rise buildings have difficulties in cleaning windows, regardless of whether residents or organizations have this real problem. There is a danger of rubbing the outdoor side of a high-rise building window glass; the windows of some building rooms are also equipped with fixed glass windows, making it more difficult to wipe them. People hope that science and technology workers will pay attention to the development of such home gadgets.
