  The HAWC observatory is an air-shower detector, which is designed to study
both astrophysical gamma-rays in the TeV region and galactic cosmic rays in the
energy interval from 1 TeV to 1 PeV. This energy regime is quite interesting
for cosmic ray research, since indirect observations overlap with direct
measurements, which offers the opportunity for cross calibration and studies of
experimental systematic errors in both techniques. One quantity that could help
for this purpose is the all-particle energy spectrum of cosmic rays. In this
work, we present an update of HAWC measurements on the total cosmic-ray energy
spectrum between 10 TeV and 1 PeV. The spectrum was obtained from an unfolding
analysis of almost two years of HAWC's data, which was collected from January,
2018 to December, 2019. For the energy estimation, we employed the high-energy
hadronic interaction model QGSJET-II-04. As in a previous work of HAWC,
published in 2017, we observed the presence of a knee-like feature in the
region of tens of TeV.
