- Two small toy poodles, they do not shed much
- Hardwood floors and large high pile rugs

I want EVERY bit of dust removed possible as I have bad allergies.

I'm confused by the M1, L1, S1, C3, C1, and then sub models of each. I just want the best one for allergies for hardwood floor and carpet. Lets assume they are high pile rugs to be sure it all gets vacuumed well.

I heard there are new models and new models may not have the same 3 tier filter system.
