OPERATION
HOW THE MACHINE WORKS
The scrub components of the machine are a
solution tank, scrub brushes or pads, a squeegee,
a vacuum fan, and a recovery tank.
The buttons on the control panel control the
machine scrubbing functions. The
1-Step button
turns the preset scrub functions on and off.
The
ec-H2O
button
(option) enables the
ec-
H2O
NanoClean
(electrically converted water)
system. The
vacuum fan/squeegee button
turns
the vacuum fan on/off and raises and lowers the
squeegee. The brush pressure buttons control the
scrub brush pressure, and the solution buttons
control the solution flow.
The steering wheel controls the path of the
machine travel. The
directional switch
controls the
forward or reverse direction of the machine. The
propel pedal controls the speed of the machine.
The brake pedal slows and stops the machine.
NOTE: The amount and type of soilage play an
important role in determining the type of brushes
or pads to use. For specific recommendations, see
the BRUSH INFORMATION section of this manual
or contact a Tennant representative.
The machine is equipped with BrainOS software
that is accessible via the
User Interface (UI)
touchscreen
, also known as the
UI touchscreen
.
BrainOS technology offers a robotic mode
feature that provides the ability for the machine
to perform floor cleaning by following one of the
saved navigation routes without direct, real-time
operator control. The machine can only operate
in robotic mode in areas where cleaning routes
have been taught and saved. The machine can
be taught standard cleaning routes or, if enabled,
an Area Fill route, where the operator teaches the
perimeter of an area and the machine determines
the best route to complete cleaning the area. The
UI touchscreen
allows an operator to teach a new
cleaning route, run an existing cleaning route
robotically, access triggered alert messages, and
more. It also provides constant visibility to current
battery life and ROC connection status.
Home markers must be permanently installed
before the machine can be used in robotic mode.
A home marker is a unique code identifier that the
machine scans to determine its current location,
as well as any routes that have been saved to that
specific home marker. The machine is designed
to work with up to 10 home markers. Each home
marker can store up to 6 routes for a total of 60
routes.
CONVENTIONAL SCRUBBING
Water and detergent from the solution tank flow
to the floor through a solution valve. The brushes
use the detergent and water solution to scrub
the floor clean. As the machine propels forward,
the squeegee wipes the dirty solution from the
floor. The suction created by the vacuum fan then
draws the dirty solution from the squeegee into the
recovery tank.
ec-H2O
SCRUBBING SYSTEM (OPTION)
When using the
ec-H2O NanoClean
technology,
normal water passes through a module where it
is electrically converted into a cleaning solution.
The electrically converted water attacks the dirt,
allowing the machine to easily scrub away the
suspended soil. The converted water then returns
to normal water in the recovery tank.
The
ec-H2O
system can be used with all double
scrubbing applications.
NOTE: Do not enable the ec-H2O system with
conventional cleaning detergents in the solution
tank. Drain, raise and refill the solution tank with
only clear cool water before operating the
ec-H2O system. Conventional cleaning detergents/
restorers may cause failure to the ec-H2O solution
system.
