BISSELL CleanView/CleanView Swivel Pet Rewind vs Shark Navigator Lift-Away Pet

In most ways, the Shark Navigator Lift-Away Pet ZD201 has the edge in performance over the BISSELL CleanView/CleanView Swivel Pet Rewind. The Shark feels better built, is easier to maintain, incurs lower recurring costs, and has a HEPA filter. However, its biggest selling point over the BISSELL is its 'Lift-Away' configuration, which makes it much easier to clean tight spots. That said, the BISSELL is the marginally better option for cleaning super-thick carpeting, thanks to its height-adjustable floorhead, which is something the Shark lacks.
