Regarding Thomasheisig post.
The cleaning machine from AP is based on the Keith Monks. Made from the former Importer of Keith Monks.
The KM is absolutely the best machine ever made and this one is Version based on it. Different name.
I agree, the problem with Keith Monks and the Loricraft is the arm is left to gravity follow the LP (groove). If you have liquid near the label it gets caught in the run out groove and does not get picked up. Plus, the string that serves as protective boundary between the high suction and the LP's surface must be moved by hand with both Keith Monks and Loricraft.
The German RCM uses a tiny servo motor to feed the correct amount of thread each time the arm traverses the LP in "reverse" (from run out groove to front of LP). This process insures clean thread during vacuuming, even when excessively applied during cleaning and subsequently flung across the LP by centrifugal force.
The retail of the German RCM is $6500.00. When Keith Monks was alive and working on a much more favorable exchange rate between Pounds, Euro's and US dollar, the Monks was about $4000.00 US dollars plus shipping from the UK.
The Monks has no motor for the string, no motor for the arm and no motor to deliver the cleaning fluid. The German machine has push buttons to accurately distribute fluid and may be ordered with twin pumps and brushes so you can use two fluids or fluid and distilled water.
So far it's no contest, I'm getting resolution I never thought possible. It does a superior job and the added cost is due to superior construction and additional features and parts not found on other record cleaning machines.
