A mopping assembly includes a mop handle having a first telescoping piece, a second telescoping piece, and a rotating mechanism extending between the first and second telescoping pieces. A choke plate is supported in the mixing passage for pivotal motion about a parallel choke plate axis between an open position and a closed position, such that airflow through the mixing passage tends to rotate the choke plate toward the open position. The wireless device communicates with the RF addressable sensor to obtain sensor data for transmission over the communications network.
