I’ve had my Dyson corded vacuum for 11 years, and it’s weight, the hassle of the cord, loud noise, etc. has been frustrating me. I bought the Shark Rocket to ditch the cord, make quick clean-ups way easier, and for the awesome under-furniture flexibility. So far, I’m very pleased with the exception of run-time. The unit boasts “up to 40 min of run time,” but I can even vacuum my whole first floor with one charge. Other than that, it has been awesome!
