Avoid the twin tank Panasonic. Awful, awful, awful. The uprights were slightly better than the cylinders but still awful when I think of the amount of times i had to clean mine out!
I have the non-HEPA version of that Panasonic twin-bin and can concur with Sebo_Fan that, although very powerful when empty with clean filters, they clog up easily and activate the suction relief valve frequently.
I must admit though not particularly quiet, Vax's paper pleated cone filters were far easier to clean and seemed to last longer than the Panasonic triple filter system in between cleans. I loved the Twin Bin design on the upright though as they were beautifully light to push and pull across carpets but they were far from deep cleaning.
