The Roomba 675 cleans using an algorithm to ensure thorough coverage. It does not clean in parallel rows so will appear random, but is not.
Sorry, there was a problem. Please try again later.Somewhat random but she does a great job. For the sale price of 100 off she could do somersaults in the middle of the floor and I would not complain. She is awesome. Well worth the price. She goes over areas more than once and thoroughly cleans. I had read reviews of some that map the cleaning in straight lines and the miss lines of dirt and dust. This one misses nothing
Sorry, there was a problem. Please try again later.This one is random, it doesn’t follow a pattern. The most expensive ones have a camera and those have a fixed cleaning pattern that supposedly it is better
