We were thrilled to upgrade to the Stylus from my old $50 upright Dust Devil that I got back in college (nearly a decade ago), and it really helped us enjoy regular cleaning - of both our house and our car. But after about 4 or 5 months, we found that it will only run for about 20 seconds then shut off, even at full charge. We suspected it was because we somehow managed to lose a couple of the pieces that go inside the dust bin. But then my mother-in-law, who bought the exact same model a month later after hearing us raving about it, retorted having the exact same issue with her vacuum about a month after our issues started. Seems like there's something wrong with the battery or motor itself, which is incredibly disappointing since, again, we really found the Stylus to be a great tool.
