The RumBot starts up in purge/prime mode to fill the hoses and flush the RumBot at the end of the party.

The stage and motor are overkill for this project.  Using a belt stage and a smaller ClearPath motor would have reduced the size of the Rumbot and would have even been faster, less expensive and safer.  Anyone who is trying to attempt a similar build should look at the CPM-MCPV-2310P-RLN
