I'm am very disappointed with this vacuum for which I had high hopes for. This vacuum is only a week old. This vacuum was not cheap. It does not work on our "very very" short pile carpet. On hard floors it works fine. I've run it over the same place three times. A few pieces of lint and 1/2 piece of thread were left behind. I inspected the lint and the thread just sitting there on top of the carpet. Dust bin is empty, filter clean, carpet mode enabled, vacuum set to max, latest firmware. Please advise. I have till the end of the month to return it. Thank you in advance.
