I saw this review.
Dyson vs. iRobot Roomba: The Home Robot Revolution Starts on Your Floor
More, including robot vacuum review below.
The author reviews two robot vacuums the Dyson, which is the company's first attempt at a robotic vacuum, and the iRobot Roomba, the company's first attempt at a non-random but linear path, or as the author says, "While past Roombas swept at random, bumping around walls and furniture like drunken sailors, both the new Roomba and the Dyson are basically pint-size autonomous vehicles. They use cameras and other sensors to map your house, keeping track of where to clean and how to recharge when necessary."
Why he did not test the superior Neato Robotics vacuum, I have no idea. Both of the robots tested are Gen 1 robots based on what they do. Neato Robotics has been making these robots for a very long time. I have owned a Neato XV-11 since at least 2010.
Here is the current Neato line-up:
Compare Robot Vacuums - Neato
I chose the XV-11 back when it was the only vacuum which, as the wiki says, ". . . travels in straight line patterns partially overlapped, with the help of a laser range finder that scans around in a full 360° circle, and the SLAM algorithm that allows it to map the room being vacuumed while it is completing its task. The Neato XV robot is able to return to its home base and charge itself when running out of energy, and has sensors that prevent it from falling off stairs. In case the robot is used in a floorpan larger than it can cover with one battery charge, the robot is able to continue cleaning at the exact spot where it left off the previous session, after recharging its batteries."
Neato Robotics - Wikipedia, the free encyclopedia
I was an early adopter, and so expected some problems. I was not disappointed. The Gen 1 had a problem where it would eventually permanently get lost in it computer map. The solution was for Neato to send me a new robot, with an enclosed shipping label, and I would then remove the new, replace with the defective, and return. I believe I had two Gen 1 robots which needed replacement. After that, the problem only would happen rarely, and was solved by shutting down the robot, and then restarting. I did have one later Gen robot that had to be sent back to the factory for the same problem. I believe that was in 2012. That was the last R&R problem.
The Neato vacuum's just as a person would in linear, overlapping lines. I have never had a problem with the vacuum not having enough power. In fact, when I first bought the vacuum, it required a few days to throughly clean the carpets because they were so full of dirt. The vacuum would fill up with dirt very quickly back then, and need to be emptied. This resolved after a week. We had a house cleaning service, and we would vacuum as needed. Humans are terrible at vacuuming, they move the vacuum too quickly and focus on surface dirt, not the deeper dirt. The robot moves at a predetermined speed, and picks up more deep dirt. The amount of dirt we had missed in our vacuuming surprised me.
The carpets look great, and I am comfortable they are cleaner than if human vacuumed.
Using a robot does require some changes. When humans vacuum we either avoid problems by vacuuming around them, or pick them off the carpet, so things like hairbands, rubber bands, paper clips, etc. we remove while vacuuming. With a robot you will need to do this first for the entire area to be vacuumed. It also pays to determine what furniture will cause problems and arrange it appropriately. Chairs/stools slow, or sometimes trap the vacuum so I tend to place them on the table, or I will use the magnetic strips to keep Robbie from going where I do not want him to go.
It takes me only a minute or two to look over the room, remove power cords, and other robot traps, set a few chairs on the table, and fire up Robbie. Because we all know that all work, and no play makes Maddog a dull boy.
This is a good review of the XV series machine being sold now:
Neato XV Signature Pro punches above its weight
Amazon has a number of different models available for prices varying from $299 up.
I like and use the Neato vacuum many times each week, it keeps the floors clean, and the house neat-o. While a bit expensive, I have not vacuumed the floor more than a few times per year since 2010, and then only because of some catastrophe. For everyday cleaning, I simply let Robbie the robot do the work.
