I bought the Shark Cordless Stratos w/ clean sense IQ about days ago, November 11, 2022.  I was pumped to try it out, and deliberately didn't vacuum for a couple of days.  I was quite disappointed that I needed to bring my older shark vacuum out to finish the job.  So I tried it again a couple days later on full power mode.  It seemed to get more dirt, but the battery went from 100% to 0% in roughly 10 minutes.  This is far from ideal, especially since the battery takes 3.5 hours to fully charge.  While this vacuum did well  on my hardwood and tiled areas, it seemed to have difficulty thoroughly cleaning medium pile carpet,  seemingly needing extra suction power / more than the clean sense IQ was putting out.  Sadly, I will be returning this.  Maybe I just had a lemon, as all my other Shark / Ninja products are amazing, but if this wasn't a lemon then it is definitely not worth the price.
