Id have to say most favorite is my Kirby Heritage 2 Legend, with the G series Hepa bags,,and my Tristar CXL. The Central Vac comes in at 3d place. Central Vac is fun to use, but is a pain in the you know what,,wrestling that 30 ft. of hose around doorways,ect. is a pain. Is handy tho for above the floor cleaning,,,vacuuming the garage, and doing the inside of the car. I can see that if you had a very large home, with alot of stair,,the Central Vac would be really handy.
