We received our 2-in-1 just over a week ago so can only give first impressions.  We like what we've seen so far.  The internet set-up was relatively easy as was the mapping.  Performance has been excellent.  Very impressed with the final results.  No problems with missed areas or dirt being scattered by the machine.  We were very surprised by the low noise level.  Much quieter than our regular shark vacuum.  So long as the unit holds up, we are very satisfied with our purchase.
