They leave the bag good-smelling, ugh, unlike wet dog hair which has been sitting there for a good month... like my aunt's Dirt Devil... I still have nightmares from that...
I love cleaning the garage with my central vacuum plugged into the inlet in the furnace room and hearing everything go through the 50 feet of hose I use down there and then through the roughly 40 feet of pipe to the Vacumaid cyclonic and hearing it then be whirled around and finally fall into the dirt bucket! Any excuse to vacuum is almost enough! LOL
