I have run this HUVI Robot vacuum R1 in my house about 6 times now.  The vacuum works well and seems to pick up a lot of dust.  Unfortunately, it gets stuck a lot.  It seems to have trouble with the transition between hard floors and rugs (I did switch from the 6 leg rotating brushes to the 3 leg ones) and it also has an issue with the pedestal base of my swivel recliners and it gets stuck in various other places.  It is certainly easier than vacuuming myself however, I can't simply start the R1 and leave the house.  I need to be around while it is running to get it unstuck.
