New technologies are optimizing modern offices for better collaboration, productivity, energy efficiency, employee health, and, believe it or not, cleanliness. And robot vacuums are a great example. They can keep your work floors immaculate so you're able to focus on tasks that really matter, like preparing for next week's big meeting or finishing up those expense reports. Neato's Botvac D5, for instance, is currently on sale through Amazon and Jet for $419, and it scans, maps and cleans your entire office area. It supports up to three floor plans and can be easily programmed to go around places you may want it to avoid.
