Unlike many window-cleaning robots, the Hobot-298 is mains-powered, with a 16.4 ft total reach on the cord. The robot weighs just over two pounds and holds onto the surface being cleaned by suction.

Perfect for cleaning huge windows or glass doors, not so great for the top panes in most home windows, as it needs to be used on surfaces larger than 16 inches square. Okay, so window-cleaning robots come in all sorts of shapes and sizes, but this time around it’s a square that’s just under 10 inches on each side. So, what’s it all about?

Yes, now I’ve got a robot to clean my windows, and I couldn’t be happier. I’ve got robot vacuums, automated lights, and now, a replacement for my second-most-hated task, washing the windows. Now, there’s no home robot for doing the dishes or even for filling the dishwasher (yet – but I live in hope), but many other household tasks can be handed off to robots.

When I look for smart home devices, I’ve got a few hard-and-fast rules, one of which is: Do I hate doing this chore? If yes, it’s a prime option to replace it with some automation, whether that’s with a robot or with some AI.
