Number 1: DREGO-Waschautomat by Wilhelm Dreusicke & Co. KG. Dreusicke was the major German tool- and spare parts maker for typewriters for decades. There is actually a German utility patent on "REINIGUNGSAPPARAT MIT SPRUEHSTRAHLSYSTEM UND SICHERHEITSSCHALTER" from 17 August 1978 (see pdf here). I am not sure whether it's the same model, but the machine shown here was produced in 1980 so this would fit. It could also be "REINIGUNGSAPPARAT MIT MOTORPUMPEN UND SPRUEHSTRAHLSYSTEM UND 2 GETRENNTEN FLUESSIGKEITSBEHAELTERN" granted 17 November 1977 (see pdf here).
