iRobot Roomba Discovery SE Robotic Cleaner

We just use it in our large kitchen area, hallway and main entry way...all wood flooring. If used and cleaned each day, it picks up all of the visible dog hair and keeps those areas looking great and dog-hair free. One has to be really lazy and expect a robot to pick up each and every particle in each and every room...especially those rooms with high-end carpets. I would rather do that myself to keep a nice house looking nice. We are about 5 years away from a product that will have enough capacity and strength to thoroughly vacuum an entire main floor...and the 5 years I predict, will include the cost of the product being reasonable enough for the ordinary home owner to purchase.
