The miele S8 are the flagship deluxe canister vacuum. All models have standard HEPA filter, electronic speed controls either on the base of vacuum or fingertip on hose.they take the larger capacity G/N bagsand all have tool storage inside. the S8 also have full wrap around bumper and a single touch 26' long cord rewind system. These models are extremely quiet and boast the nicest colors. The best designed vacuum in the world in my opinion.
