Robots are a knotty problem for humans. Some people fear and loathe them while others place them on pedestals. We've become dependent on them in some arenas -- military, medical, and industrial, for instance -- yet we blame them for upcoming societal ills. They've infiltrated our books, movies, television, and Interweb. We tout their potential while building more of them despite their dangers. It might be possible that robots will collectively outlast us, yet we still insist on having them in our homes.
This fascination with anything mechanical is natural, as was the incarnation of iRobot, founded in 1990 by three MIT graduates who specialized in warbots. The company has recently announced their sale of their defense and security department so as to focus on connected-home products. Since they already commandeer the majority of the floorbot industry, it's highly likely that one day they will own all of it, especially if they keep rolling out housebots like the Roomba 760. The 760 is a later version of the iRobot Roomba 440, iRobot Roomba 595, and iRobot Roomba 645, and has much in common with them.
The 760 utilizes a 3-stage cleaning system whereby the side brush gets wall edges, the counter-rotating brushes sweep and scoop, and the AeroVac Series 2 sucks up debris and pet hair. Dual HEPA filters ensure that the robot leaves behind only fresh air, thus saving your lungs additional hardship. Acoustic sensors lead the Roomba to the filthiest areas, over which the Persistent Pass cleaning pattern -- a back and forth motion -- is then applied. iAdapt Technology enables multiple cleaning, and includes stair and obstacle avoidance. The 760, like the earlier models, recognizes carpet fringe and can self-adjust to carpet, linoleum, and hardwood.
The 760 can be scheduled for up to seven cleaning sessions per week if you're not home, and is provided with a remote control so you don't have to get up even if you are. Its software results in a 50% longer battery life than prior Roombas, which means it's good for hundreds of cleaning cycles. Included are an extra set of HEPA-type filters, a side, bristle, and beater brush, self-charging home base with power supply, 2 virtual walls, and 2 cleaning tools.
I have carpet and hardwood floors and this thing really makes the floors look good. Quite operation too.
While I used the robot I loved it. It picked up most of the visible dirt and cleaned a large portion of the ground floor (4 rooms).
I love the two HEPA filters, which are easily blown out with a can of air or compressor after a vacuuming session.
The vacuum strength could be better. I recommend vacuuming the HEPA filters after each use to extend their life and improve on-going performance.
