The Winbot 950 Is Like Roomba for Your Windows

You learn a lot of things—few of them pleasant—when selling a house. When I put my brownstone on the market a few years ago, I hired a team of professional window cleaners to come and give my windows a good going over. Burly guys with the precision of figure skaters ran soapy squeegees and T-bars encased in fluffy sleeves over the glass, doing more to improve the look of my home than all the dusting, mopping, and HGTV-inspired staging I could muster.

The lesson was twofold: Clean windows make a huge difference, and keeping them that way is harder than it looks, especially if you’re doing it yourself. That’s why cleaning the windows of my apartment has earned a perpetual place at the top of my to-do list, above even the more necessary tasks of repainting and regrouting.
