Premium shares the same core technology and capacity as Comfort but adds a sleeker design and several convenience upgrades: a soft-close lid, a Teflon-coated bowl so liners slide smoothly into the incineration chamber, and an advanced digital menu with an incineration-cycle counter/timer, a steam-cleaning filter program, and a front hatch that locks and opens only from the display menu.
