This head replaced my 25 year old SEB 217 (no suffix, original design). Although it costs the same as a brand new vacuum cleaner, 25 years of quality speaks volumes. The original required a motor and brush, the cost exceeding the price of a new complete assembly. Thanks to the perfect coordination with the Power Wand, Miele has retained this design. The original vacuum tank is also original, just a new plug after so many years. At Miele you get what you pay for. No flashy disposable blocks worth their money. For comparison, a 10-year-old Bissell carpet cleaner had several motors, pumps, heaters and valves replaced.
