Woot had a Roomba robot vacuum cleaner available at a very good price last week, so I ordered one. I received it on Saturday and on Sunday I gave it a try-out while I watched football.
It’s really an amazing device, and yes, it actually works! I set it to cleaning my fairly cluttered living room, my dining room, kitchen, and the hallway leading to my upstairs bedrooms. I live in a fairly large house and these rooms are all quite sizeable. It took a total of about 2 hours for it to get them all clean.
It’s really fascinating to watch in action. It uses a variety of touch and infrared sensors to navigate about the house. It seems to use some simple algorithms to determine where to go along with some pseudo-randomization to make sure it covers the entire room. Leave it alone and it will eventually manage to traverse every square inch of a room. It vacuums quite well, whether on rugs or hardwood or kitchen floors. It actually did an outstanding job, even along the baseboards where it used its wall-following algorithm. It even manages to navigate well underneath tables and any other furniture it can fit under. When it encounters what it considers a dirty area, a bright blue light goes on and it spirals around in that area until the area meets the robot’s cleanliness standards, and then it continues on its way. Overall, it did a much more thorough job than I would do with my Hoover vacuum cleaner. It took longer than I would have taken, but I was able to watch football from my couch while it did all the work. Not a bad deal!
The picture shows Robbie (what other name could I give him?!?!) sitting in his charging unit. He finds it himself when you tell him he’s done, and rolls up to it, turns himself off, and starts recharging. Also in the picture are the two Virtual Wall units that came with him. They allow you to wall off areas that you don’t want Robbie to go into. They will project an infrared beam up to 8 feet in length that Robbie treats just the same as a wall. Robbie is also smart enough not to fall down stairs. I purposely left the downstairs stairway door open in the kitchen and watched him approach the stairway a couple of times and then gingerly back-off and reverse course.
So far, I’m one very happy robot owner. Robbie has taken over one chore I find somewhat tedious to do, and he does it better than I do. My house is now going to be cleaner than ever!
