I learned so much about new technology in the vacuum cleaner field. My guest, Toufic Khayrallah (he said we could just call him T.K.) represented Sirena Water Vacuum - the most advanced vacuum in the world. Sirena does not use bags, it eliminates allergens, pet hair & odors from the home, harnesses the power of water to effectively clean carpets and furniture, provides indoor air quality - and much more. It comes with lots of attachments and takes the places of multiple other cleaning aids. The "wow" factor came when he demonstrated using the vacuum and then opened the water bowl to see what all was in there!
