I spoke to John Van Leuven a few weeks ago who's the CEO of SEBO USA, and there aren't any new models coming out anytime soon at least not here in the US. He mentioned that some of the models like the Felix could use a facelift, but the only thing new we've already gotten from SEBO just recently are the limited edition pastel colors that'll be available for at least a couple years.
It'll be interesting to see the new Miele L1, I'm already concerned about what's underneath. If there's alot of circuitry, it'll be a pass for me just like their bagless models. I loved the C1 Classic models when I worked at a Miele dealer, they're just so simple. If I wanted the most powerful canister on the market today, it'd be the C1 Classic Homecare Powerline. But if I could choose any canister on the market today, it'd be the SEBO E3 Premium because in my opinion it's the best of the best.
I wouldn't recommend a Eureka Mighty Mite if the floors are wood cause they'd scratch them, a Bissell BGC3000 would be a better choice. I don't care much about any canister that has a shoulder strap, they're so uncomfortable for myself where I'd rather take a backpack instead as long as it's bagged. I'd also take a Simplicity Jill over a Bissell Zing cause they have better filtration. Kenmore is likely history by now. My recommendation for a bagged straight suction canister today would be either Miele or Numatic.
