[0169] As shown schematically in FIG. 14, a closed air duct or conduit 552 is connected between the fan housing exit port 518 and the air jet port 554 of the first cleaning zone A and delivers high pressure air to the air jet port 554. At the opposite end of the first cleaning zone A, a closed air duct or conduit 558 connects the air intake port 556 with the integrated liquid storage container module 800 at a container intake aperture 557. Integral with the integrated storage container or tank 800, a conduit 832, detailed below, connects the container intake aperture 557 with a plenum 562. The plenum 562 comprises a union for receiving a plurality of air ducts connected thereto. The plenum 562 is disposed above a waste storage container portion of the integrated liquid storage container or tank module 800. The plenum 562 and waste container portion are configured to deposit loose particulates suctioned up from the cleaning surface by the air intake port 556 into the waste container. The plenum 652 is in fluid communication with the fan intake port 516 via a closed air duct or conduit comprising a conduit 564, not shown, connected between the fan assembly and a container air exit aperture 566. The container air exit aperture 566 is fluidly connected with the plenum 562 by an air conduit 830 that is incorporated within the integrated liquid storage tank module 800. Rotation of the fan impeller 512 generates a negative air pressure or vacuum inside the plenum 560. The negative air pressure generated within the plenum 560 draws air and loose particulates in from the air intake port 556.
