Unissued-unused vacuums NIB-I JUST CAN'T resist--have to use it!!!I purchased the Riccar Radiance many years ago too,when they first came out.I like the machines but like the Kirbys better.Now,if the airpath in the tandem air machies was simpler-the performance would be even BETTER-and I would like to see a bell nozzle instead of the square base.The bell nozzles just get into corners,around furniture and closer to walls,and you can use EITHER side of the nozzle!No being blocked by a belt housing or the "weak" side where the suction intake isn't.
