Powerful, lightweight and versatile. The duo brush heads do an amazing job whether it's on carpet or hard floors. The mini brush head works great on couches for pet hair and also on carpeted stairs. It completely embarrassed me after I used it on a carpet I thought was clean with how much dirt it picked up. Now I know my carpet is clean.
