Don't get too excited ... yet That's not to say iRobot will make robotic lawn mowers ubiquitous overnight. On one hand, for example, revenue from robotic vacuums currently comprises only 15% of global vacuum sales. On the other hand, according to iRobot co-founder and CEO Colin Angle earlier this year, that's roughly the same market share held by other now-common household appliances around the same stage in their respective release cycles (10 to 15 years following introduction), including the microwave and dishwasher. It will almost certainly be a matter of years, then, before robotic lawnmowers can make a similar claim. But in the meantime, investors can look as an early example to Europe, where robotic lawn mowers already represented a roughly $200 million market last year. Keeping in mind iRobot's current guidance calls for total 2015 revenue of$625 million to $635 million, even securing a small slice of this growing global market could represent a significant opportunity for incremental revenue.
