Miele Complete C3 Cat & Dog

The C3 Cat & Dog is what you buy when pet hair comes with allergies, odor, or the intention of owning one vacuum for the next fifteen years. The Electro Plus powerhead agitates carpet deeply enough to pull out fur that bagless uprights leave behind, and the sealed bag system is the machine's real argument: a 4.76-quart self-sealing bag means you never see, smell, or breathe the hair you collected, and the active charcoal filter measurably tames litter-box and wet-dog odors. Build quality is the other argument — Miele designs these for a 20-year service life, and the used market treats them accordingly. The costs are equally clear. At roughly $1,100 to $1,300 it is the most expensive non-robot in its class, replacement bags and filters run a real if modest annual cost, and a canister on wheels is simply less convenient to drag around than an upright is to push. The 12-pound canister is light, but the hose-and-wand workflow has a learning curve. For allergy households and homes with serious odor problems, nothing bagless competes; for everyone else, the Shark Stratos gets close enough for a third of the money.
