Having a robotic vacuum scoot around your home sucking up filth isn't all that novel. But if your current rolling dust buster just isn't cutting it, Neato just updated its D-series line. The Botvac D75, D80 and D85 all sport the new spiral blade brush that Neato says offers the same cleaning power but much quieter than previous models. The vacuums still use a laser-guided system to clean floors without wandering around in a circle and squared edge helps it get into corners. Thanks to a new design, the guidance system disk no longer looks like a a Play-Doh lid. The Botvac D75 starts $499 while the D80 and D85 with quieter brushes and high performance filters will set you back $549 and $599 respectively.
