Roomba, the popular robotic vacuums, have a new trick up their sleeve. After learning how to map the physical space of a home a few years ago, the little robo vacs are now learning how to map the Wi-Fi coverage of a house, according to a report from TechCrunch.

As the robot roams around your house cleaning, it will now periodically log the Wi-Fi signal strength throughout the house. The data will be saved in a new Wi-Fi coverage map, which will live inside the Roomba app alongside the cleaning coverage map. Wi-Fi mapping will launch later this month as part of an app update and will mark the launch of a new beta program for the Roomba app.

Roomba won't do upload and download speeds for the house, but it will log the signal strength in decibels, giving you a nice gradient map at the end of a cleaning cycle. The app will even point out which areas have "poor" Wi-Fi coverage, giving you a good idea of how to tweak your cool new mesh networking setup.
