This is the description of a record cleaning machine I built. It uses an industrial wet vacuum cleaner with 1000W to suck the cleaning fluid from the record. The fluid is applied by swinging a tube over the record and pumping with a manual pump. The platter is rotated manually and a normal paint brush can be used to get the dirt out of the grooves. I use a professional brush from a Moth record cleaning machine. After that the sucking tube is swinged onto the record (please don't forget to glue the velvet onto the tube, or the first record you cleaned is cleaned to death) and the vacuum cleaner is switched on. One or two spins should be enough to suck all the fluid with the dirt away.
Above is a top view of the record cleaning machine. The plinth is a box which is about 10cm high. I used MDF because it is good if the whole thing is rather heavy, so that the machine does not move while vacuuming. The vacuum is rather high as the air slit is very small compared to a cleaning tube of a vacuum cleaner.
