The AIRBELT E2 model is straight-suction vacuum.
Turbo Head and Parquet Brush, or Kombi Nozzle, but No Power Head - The E2 model has a telescopic tube and suction hose without integrated power cord, so it does accommodate electric power heads. Instead, the E1 Kombi comes with only a combination nozzle, with retractable bristles, to clean hard floors and rugs. The E2 Turbo comes with an air-driven turbo head for rugs, and a parquet brush for hard floors.
Suction Adjustment Switch on Canister Body - Because the E1 and E2 models have hoses and telescopic tubes without power cords, their suction adjustment switches are located on the canister body, not the handle.
