The electric brush of this model is larger (wider) than that of VCH-8831, however, it can only be used if the hand vacuum cleaner is connected to the long Saugstil, has made him a normal vacuum cleaner. By contrast widerum not work the motorless attachments for upholstery and joints with the great combination, but only with the taken-out Handstaubsauger alone. So when "large" vacuum cleaner he always works with the electric brush, as always without small (but with one of the alternative essays).
By comparison, the VCH-8831 is a pure hand vacuum cleaner, fit the but both the motorless essays (with extension elements, of which 3 are doing), and the electric brush (no extension possible), but only about half as wide fails here ,
Unfortunately all work Grundig models with NiMH batteries without overcharge protection. Either one cherishes and cares for the built-in battery, or it is weak and fast breaks - served principle. It's time that here lithium-ion / polymer battery technology is used.
