After a six-month delay to hone the robot to Japanese homes, and a year after the original launch announcement, the Dyson 360 Eye robotic vacuum cleaner went on sale in stores all over Japan and in Dyson's new flagship retail store in Tokyo.

A recent TechNavio analysis of the residential robotic vacuum cleaner market forecasts a CAGR of 6.43% over the period 2015-2019. Another research firm predicts a 15% growth rate over the same period. Robovacs (as robotic vacuum cleaners for carpets and floors are called) still form a small percentage of the global vacuum cleaner market (18% according to Colin Angle, CEO of iRobot, maker of the Roomba line of robotic vacuum cleaners), but their acceptance is growing at a steady pace, whether it be 9% or 15% or somewhere inbetween.

The Dyson 360 Eye system is novel in that it creates a panoramic 360º view of the room it's working on and then navigates by triangulating fixed visible points in that room. The video below is quite informative on the navigational process:

Dyson plans to launch the 360 Eye robot vacuum in the US, China and Europe during 2016.

Today, vacuums represent just half of Dyson's $2.1 billion in sales. Dyson's technology pipeline for the next few years includes hiring 3,000 new people, launching 100 new machines, and launching four brand new product categories — all by 2020.

Advanced robotics will change the world of engineering for good. At Dyson, we’ve been developing robot technology for over 15 years – 200 engineers, 420 patents and £28m has already gone into our first robot vacuum. But our Dyson 360 Eye™ robot is just the start. The team is advancing the systems that make our robots more intelligent – able to understand environments and navigate with complex sensors and algorithms. The future is robotic.

Robotics Trends compared the 360 Eye to iRobot's Roomba 980 in a side by side chart that seems to show very similar functionality and pretty high selling prices, particularly Dyson's which sells for $250 more than the Roomba). Dyson claims it's vacuum generates the highest suction of any robot vacuum; both have comparable software apps but iRobot claims that the Roomba's low height enables cleaning in places where the Dyson can't go. Also, the vision systems are different particularly in how they map the area, plan their work and localize where they are.

Only sales figures from the marketplace will tell the real story of how consumers perceive any differences.
