1. A cleaning device for cleaning a sample cell of a turbidimeter, comprising:
a sample cell cleaning assembly comprising a cleaning component and a tube extending from a bottom tip of the cleaning assembly to a location outside the sample cell, wherein at least a portion of the cleaning component contacts an inner diameter along a longitudinal length of the sample cell;
a movement device;
a processor operatively coupled to the sample cell cleaning assembly and the movement device; and
a memory storing instructions executable by the processor to:
move, using the movement device, the assembly into the sample cell, wherein upon introduction of the assembly into the sample cell the tube is opened on the assembly, thereby providing a secondary flow path from within the sample cell to a location outside the sample cell;
engage, by moving the cleaning component using the movement device to move the assembly, a cleaning functionality of the assembly, once introduced into the sample cell and the cleaning component contacting the inner diameter of the sample cell, to clean the sample cell; and
remove, using the tube, a plurality of particles from the sample cell via the secondary flow path, wherein the plurality of particles comprises residual particulate of a prior sample.
