I always said I would never be that lazy. Well I am now, I have my Bissell Robot set for 3 times a week to clean up my wood floors. I no longer look up the hall and think where on earth has all that dust come from. It is amazing as the dirt container is almost full reach time it gets used. I would no be with out it now. Thank you Bissell you products are always above the rest. Keep up the good work.
