the window gets dirty way too fast, it's really annoying to deal with so frequently and it should be tweaked to gain dirt much slower, maybe even not gain dirt at all after you clean it
maybe it could sometimes get dirt on it when it rains? though it wouldn't make sense to happen on the inner side of the window, it would happen on the outside
also the mop should have a lot more range than it currently has, cleaning the window is especially more annoying when you can't easily reach the upper part of it despite the fact that the mop should have enough range to easily reach it
