I have crippling artheritis..this little bot is a godsend. I also have a robot vac, and between both of them I can keep my pet hair strewn home clean and fresh...this does an excellant job on my large underground home's wood floors. it gets in corners and under most furniture. the reusable pad are machine washable. the map feature is really good and the ap is easy to understand and use. I feel this is the best on the market. well worth the money.
