Your Roomba is filthier than you think. Here's how to get it completely clean

There's a lot more to keeping your Roomba clean than simply emptying its bin now and then. Take a closer look at your Roomba's brushes, for example, and you'll probably see they're tangled in hair. A Roomba's cliff sensors, which help to keep it from tumbling down the stairs, can likewise become blocked by a layer of grime, while its dust filter will gradually become clogged with debris. If you give your Roomba the occasional deep clean, you'll not only extend its life, you'll also boost the quality of its cleanings. Our Roomba cleaning guide will take you through four primary areas when it comes to keeping a Roomba spic-and-span: cleaning its brushes, cleaning its wheels, scrubbing its sensors and charging contacts, and cleaning its dust filter.
