Let me tell you, I have a cleaning service with over 40 houses. I buy these Bissell Zings buy the truck loads!! 5 years ago was using the blue ones and when these green ones came out I decided to try them.. I bought 5 at a time and passed them out to my cleaners.. The sand and hair stands no chance with these little green "MEAN" machines!!! I've now been recommending these "Lil Wonders" to my owners for their rental and personal homes!
