At Harry Reid International Airport 
(LAS) in Las Vegas, autonomous 
floor scrubbers begin their 
overnight work with very little assistance. 
Each machine fills itself with water and 
cleaning solution, leaves its station and 
follows a predetermined route through 
the terminal. When it needs more water, 
additional battery power or a place to empty 
its tank, the unit automatically returns to its 
station before heading back out.
The machines also report what they 
accomplish. 
Scott Kley, 
managing director 
of Aviation, Terminal 
Operations for 
the Clark County 
Department of 
Aviation, shares data 
from a recent shift for 
one unit as an example. The machine had 
a total runtime of 5 hours and 17 minutes, 
including 4 hours and 16 minutes of 
active cleaning, and it used 48.5 gallons 
of water and 15 ounces of detergent.
“We can take all this data and see 
how much we are actually accomplishing 
every single day,” Kley remarks.
Naturally, the autonomous units do 
not make strategic decisions about 
scheduling. Airport operations change 
too quickly for that.
“The flights are never standard,” 
Kley says. “You get delays, mechanical 
issues, ground stops, anything that can 
kind of manipulate the way the robot 
works.”
The combination of automation, 
information and human judgment being 
leveraged at LAS illustrates where 
autonomous airport cleaning is headed. 
The first phase put robots to work. The 
second added sensors to reveal what 
is happening throughout the terminal. 
The third phase, which is still emerging, 
connects those technologies with real-
time flight, gate, weather and facility data 
to help determine what needs cleaning 
next and where human employees can 
have the greatest impact.
