I was waiting for up to a year for shark to release a new model upright and out of the blue I decided to check sharks website and there it was the new stratos! I bought my new shark stratos a month ago and vacuumed with my old kenmore first and then vacuumed again with my shark and I was amazed at how much my shark sucked up after my old kenmore.
I will definitely purchase a shark vacuum again plus I told my family and friends to buy one
