This week on the Gadget Lab Podcast, the gang talks about wellness tech, funky robotic vacuums, and a stylish smart thermostat.

Reviews editor Michael Calore and Gadget Lab editor Jon Phillips start out the podcast demonstrating the Jawbone Up, a wristband that monitors its wearer’s various health stats. It records all sorts of health-related data, such as the number of steps you take during the day, and how long — and well — you slept during the night. This $100 high-tech bracelet pairs with a free iPhone app for checking out and analyzing your healthy (or unhealthy) habits.

Next, Gadget Lab intern Alexander George pits four robotic floor cleaners head to head: the iRobot Roomba, the Neato Robotics Home Vacuum Cleaner, the LG Homebot and the Mint Automatic Floor Cleaner. The winner of this epic battle? Hard to say, as it mostly depends on your needs. Still, it’s pretty entertaining to watch these robots duke it out.

To close up the show, Michael and Jon talk about the Nest Thermostat, which is kind of like the Prius of thermostats. It’s an energy-saving, “smart” thermostat that learns your behaviors via artificial intelligence. It’s not all brains though: It’s a looker too, and designed by the guy behind the iPod, Tony Fadell.
