I researched and debated buying this product for a couple of months before purchasing. I AM NOT DISAPPOINTED IN ANYWAY. I run it every day sometimes twice a day and the dirt chamber is always full of dirt, cat hair, bird feathers, bird dander, bird pellets and even my hair. My floors are so clean == I am so happy! I have one wall to wall carpet left in my home which I am planning to replace with laminate flooring. It is thick pile and pine green (dark carpets show everthing, lint, cat hair) its a nightmare. Well I never expected this little robot to clean it as well as a full size vacuum but IT DID!! I bought the warranty so no worries for at least 3 years. I am getting rid of my full size vacuums and keeping only this. I might even buy the Scooba to mop the floors. Waiting on that one for now. BUY THIS - YOU WONT BE SORRY. My floor cleaning days are over! I hope someday there really will be a Rosie the Robot for sale. Counting the days.
Regular one and Roomba each have their unique advantage, I personal think they can not replace each other. Roomba is great when you only want to vacuum once a month, and it cleans your under-sofa, under-bed area like magic, the only thing it does not so well in is the corner cleaning
We have dogs and no carpet. That's great, but requires daily broom and vacuuming. However, now that we have a roomba the house is always spotless. We have it set to run at 3am while we're sleeping. It is loud, so the bedroom is done one a week while we're away. Our house is 2100 sq feet. The roomba does the whole thing and then returns to the base station. The only maintenance is routing emptying of the tons of dust and hair it picks up. No regrets.
