Still think robots aren’t useful? Check this one out. It’s called the iRobot Looj, and it cleans your gutter so you don’t have to spend half a day shinning up and down a ladder doing the job yourself.

It stands 2.25-inches high, and sweeps out dirt, leaves and other debris while you settle down for a nice cup of tea. Or, if you’re like us, gather all your neighbours round to boast about your new gutter-cleaning robot.
