I researched for some time looking for a vacuumed that was powerful & versatile for floor & carpets.  I am a senior so I also wanted lightweight.  I mentioned it to the doctor that I Nanny for in their 3 story mansion.  He said our cleaning lady asked me to get rid of the fancy dyson we had & buy the Shark rocket corded stick!    That was good enough for me!  I am very happy with my purchase
