When the Hye family was here for the wedding and staying at the Palace, which they totally loved btw, my sister-in-law Sandy was using the small red carpet sweeper to cleanup. She said she loved it. We discussed it and googled it. Turns out it is a Fuller Brush Electrostatic. Anyone know from where it came? Also turns out they are still available. Back in the 50s and 60s Fuller Brushes were sold door to door.
