The ZU561 packs three useful ideas into a mid-priced upright. A self-cleaning brushroll strips pet hair as it works, so you avoid the scissors chore that plagues cheaper rolls. A lift-away pod gives you a lighter unit for stairs and furniture, and the maker says an anti-allergen complete seal with a HEPA filter traps over 99.9 percent of dust and allergens.
Next to the Navigator NV352 it adds the self-cleaning roll and the seal, and next to the Kenmore Intuition it uses a cup rather than a bag. That makes it cheaper to run, though emptying the cup releases some dust.
The seal depends on rubber gaskets, so inspect them every few months for cracks and keep the cup seat clean. Wash the foam and felt filters monthly and let them dry for a full day, check the roll ends for the odd strand and wipe the pod joint with a dry cloth. Seat the pod until it clicks, because a half-seated pod leaks air and the machine seems weak. Empty the cup outdoors into a bag held tight to the opening, since a sealed machine still releases a puff of fine dust when the cup opens, and rinse the cup now and then, letting it dry completely so no damp film builds on the walls. If you have a long-haired pet, expect to glance at the roll ends every month, because even a self-cleaning roll lets a few strands reach the bearing, and a roll that no longer turns freely loads the belt and shortens its life.
