I liked it in the beginning, but then, slowly, the battery began to stop holding a charge. I know that's normal, but it seemed to happen within 4-5 months. I just didn't want to keep buying Swiffer Vacs every few months, so I decided to invest in a Dyson dc35. It has a lithium ion battery. I've had it for almost a year, and it's still going strong.
I have 2 dogs, and I use it just about every day in my kitchen/foyer to clean up the dirt and dog hair. I have laminate floors there, but I've used it on ceramic tile and berber carpet in other rooms. It is great for quick vacuuming jobs. I also like to use it in the cars.
