Before leaving the North American market, Panasonic had some of the most highly rated bagless canisters on the market - also sold as Kenmores.
They seem to be continuing to innovate and improve their bagless canisters in Japan. The clip below shows a new cleaner with lots of great innovations: stainless steel cyclone parts, completely washable dirt bin assembly, dirt-compacting cyclone design, headlight on floor nozzle AND wand end, quick draw dusting brush on wand end.
The only innovation I question is that new, very long, hose handle. Probably makes it very comfortable when cleaning floors, but I wonder if it is removable so you can clean in cramped spaces like car interiors and furniture drawers.
