COMPONENTS OVERVIEW

l

o

There are a number of physical components that play a vital role in fl oor scrubbing, as well as robotic operation.
Familiarize yourself with all components and controls before using the RoboScrub 20.

SOLUTION FILL PORT AND FILTER

The solution fi ll port is where you pour a premixed solution of an approved
cleaning chemical and clean water. The solution tank can hold up to 18 gallons
(68 liters). Use appropriate personal protective equipment and pour the
premixed solution into the solution fi ll port. Use the solution tank site gauge to
guide you as you pour. Do not overfi ll.

SOLUTION TANK SITE GAUGE/DRAIN HOSE

The solution tank site gauge/drain hose serves two purposes: as a visual
indicator of the solution tank volume and is used to drain the solution tank.
Using appropriate personal protective equipment, drain the solution tank by
removing the hose from the clip, removing the cap at the top of the hose, and
lowering the hose to drain.

WARNING LIGHT

The warning light fl ashes when the RoboScrub 20 is operating in
robotic mode. This serves as an indicator to passersby that the RoboScrub 20 is
currently in operation.

14 988767UM REV A • Content Subject to Change

EMERGENCY STOP

h

an

START/PAUSE

The RoboScrub 20 is equipped with two emergency stop buttons, one on the rear

T

and one on the control console. The emergency stop buttons should only be used
in emergency situations, as this potentially releases all fl uids onto the fl oor causing
a slipping hazard. When one of the emergency stop buttons is pressed, all scrubber
functions are immediately stopped and the in-process robotic route is terminated.

The RoboScrub 20 is equipped with a blue start/pause button on the back that is
used to begin running a saved route in robotic mode, or to pause an in-process
robotic route. When pressed, the scrub brush raises. The squeegee stays down and
the vacuum remains on for approximately 20 seconds, after which the vacuum turns
off and the squeegee raises. Always use the start/pause button to pause a robotic
route for standard, non-emergency situations.

BATTERY COMPARTMENT

The batter y compartment houses the batteries, batter y connections, and the onboard
charger. See UNPACK ROBOSCRUB 20 and BATTERY CHARGING for details.

15Content Subject to Cha nge • 988767UM RE V A

RECOVERY TANK DRAIN HOSE

The recovery tank drain hose is used to drain the recovery tank. Use appropriate personal
protective equipment to drain the recovery tank by removing the hose from the clip, removing
the cap at the top of the hose, and lowering the hose to drain.

RECOVERY TANK SCREENED FLOAT

Inside the recovery tank is a screened fl oat. When the recovery tank is overfi lled or a large
amount of foaming is present, the screened fl oat blocks the vacuum intake inside the tank
protecting the vacuum motor and internal electronics from water damage. It is essential to
keep the screened fl oat clean and functioning properly.

OPERATOR SEAT/TANK LID

The operator seat is equipped with two sensors: a pressure switch under the seat cushion to prevent joyriding during
robotic operation, and two contact switches located on the back of the seat and the body of the RoboScrub 20. It also
serves as the recovery tank lid.

CONTROL CONSOLE OVERVIEW

The Minuteman® RoboScrub 20, powered by BrainOS, was designed with total operator ease of use in mind. All controls
and components have been designed as a total system to effi ciently clean dirty fl oors. The control console consists of
the User Interface (UI) Touch Screen, also referred to as the UI or touch screen, and a number of manual controls.

Before using the RoboScrub 20, familiarize yourself with all components and controls.

USER INTERFACE (UI) TOUCH SCREEN

The RoboScrub 20 is equipped with BrainOS software that is accessible via the User Interface
(UI) Touch Screen, located on the left side of the control console. BrainOS technology offers a
robotic mode feature that provides the ability for the RoboScrub 20 to perform fl oor cleaning by
following one of the saved navigation routes without direct, real-time operator control. When the
Minuteman® RoboScrub 20 is turned on, the BrainOS software will automatically initialize (as
shown to the right).

Once the BrainOS software has initialized, it is ready for use. The top of the touch screen
displays the current time, battery life, and ROC connection status. In addition, the touch
screen allows an operator to run an existing cleaning route robotically, teach a new cleaning
route, and access to a variety of settings. See ROBOTIC OPERATION for details.

ROBOTIC MODE OPERATION

The RoboScrub 20 is equipped with BrainOS technology that offers a robotic mode feature. Robotic mode 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. BrainOS software is accessible via the UI touchscreen, and provides access to teach a new cleaning
route, run an existing route robotically, access triggered alert messages, and more. The UI touchscreen also provides
constant visibility to current battery life, the number of hours the machine has operated, and ROC connection status.

ESTABLISH HOME MARKERS

Home Markers must be permanently installed before you can begin using the machine in robotic
mode. A Home Marker is a unique scan code identifier that the machine scans to determine its
current physical 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 Marker. Each Home Marker can store up to 6
routes for a total of 60 routes.

Home Markers are used to establish the start and end point of a cleaning route. The number of Home
Markers needed may vary, depending on the size of the space where the machine will be operating
in robotic mode.

• Multiple Home Markers may be necessary for large or unusually mapped areas where more than 6 cleaning routes
are needed.

• Establish a unique Home Marker for each floor of a multi-level building.

• Install Home Markers in a permanent location on an open wall or column near commonly cleaned areas that do
not change from day-to-day. If the Home Marker is moved even slightly, the route may not be performed correctly.

• Install Home Markers at a height of 40 in (100 cm) from the ground.

• Install Home Markers so that the machine can easily scan with its right side camera at a distance of no less than
24 in (61 cm).

• Affix the Home Marker securely to the wall.

• The entire Home Marker must be clearly visible, not hidden behind furniture or shelving.

• Do not install Home Markers near stairways, fire exits, or fire, first aid, or emergency equipment.

• Do not photocopy, laminate, or place Home Markers in a glossy sleeve or cover, as this may prevent the machine
from being able to scan.

• If a Home Marker is lost or damaged, contact customer service for a replacement.

ROC: ROBOT OPERATIONS CENTER

BrainOS software provides access to Brain Corp’s Robot Operations Center, also known as the ROC. The ROC is a cloud­based robot operations center, managed by Brain Corp technicians, that enhances the machine’s abilities by providing
monitoring and analytics. The ROC is connected via a 4G LTE modem and does not require user interaction to connect.
New versions of BrainOS software are automatically uploaded to the machine without disrupting service or operator
interaction.

There is a ROC indicator on the UI touchscreen’s status bar. When the indicator is orange, the machine is successfully
connected to the ROC. If the indicator is gray, the ROC is not connected and cannot be paired with a cell phone.

PAIR A PHONE TO THE ROC

Before running a cleaning route in robotic mode, it is recommended that the operator pair their cell phone to the ROC.
When a cell phone is paired to the ROC, the ROC will send SMS or MMS messages to the phone whenever the machine
encounters an alert and/or when the route is complete.

To ensure only the onsite operator receives alerts from the ROC, only one phone number at a time can be paired to the
ROC to receive status alerts. A paired phone number is automatically discarded when the machine is turned off or a new
phone is paired.

Perform the following steps to pair a cell phone to the ROC:

1. Insert the ignition key and turn to the right
(clockwise) to turn on the machine. Wait
for the UI touchscreen to initialize.

2. Enter the 4-digit PIN via the UI touchscreen.

BEST PRACTICES WHEN TEACHING A ROUTE

• Drive in a straight path as much as possible.

• Don’t teach a route with an incline or decline.

• Don’t teach routes that include driving into an elevator or automatic doors.

• Avoid sudden turns and/or turning the steering wheel too sharply when driving.

• Maintain a safe distance of approximately 1½ ft (18 in) from the edge of ramps, platforms, cliffs, and glass.

• Avoid U-turns. The RoboScrub 20 requires a width of at least 8½ feet to perform a U-turn. Avoid making U-turns as
much as possible.

• Avoid tight spaces. The RoboScrub 20 requires a width of at least 3½ feet when driving a straight line and 4½ feet to
make turns around a corner or when turning into an aisle.

• Teach routes when the area is mostly clear of obstacles and people that may block the RoboScrub 20’s path.

• If a route is taught in an area with obstructions that are later removed, the RoboScrub 20 will not clean any areas
previously occupied by those obstructions.

• Once a route is taught, test it to ensure the RoboScrub 20 can perform the route in robotic mode successfully. If many
assists are triggered during the test run, the route may include maneuvers that are diffi cult to perform robotically.

• Avoid teaching routes over 45 minutes long. The RoboScrub 20 runs at approximately half speed when operating in
robotic mode; therefore, it can take up to 1½ hours to robotically clean a route that only took 45 minutes to run manually.

FOR SAFETY

• The steering wheel may rapidly and
unexpectedly move while operating in robotic
mode, which could cause physical injuries. Do not
sit on the operator seat, hold the steering wheel,
or put your hand or arm through the holes of the
steering wheel while the machine is operating in
robotic mode.

• The operator seat and steering wheel have
joy-ride sensors. If a person attempts to sit on the
seat or hold the steering wheel when operating in
robotic mode, the machine will automatically stop
and trigger an alert.

If the machine repeatedly triggers an alert in the same place on a cleaning route, even when there are no
obstructions, there could be an environmental factor such as a refl ection causing the machine to sense
an obstruction in the cleaning path. For help resolving the issue, contact customer service and provide
the Home Location Code number, route letter, area of concern, and pictures of what the machine sees (if
possible). Customer service may be able to remotely adjust the route to improve performance.

37Content Subject to Cha nge • 988767UM RE V A

BEST PRACTICES WHEN RUNNING A ROUTE

• Remove any rugs, fallen items, or large debris from the fl oor.

• Sweep the fl oor.

• Pair your phone to the ROC to receive text messages whenever the RoboScrub 20 encounters an alert and/or when the

ROBOSCRUB 20 FAQs

FREQUENTLY ASKED QUESTIONS AND ANSWERS

Q: HOW LONG OF A ROUTE CAN I TEACH?

A: As a general rule, it’s recommended to teach 45 minute routes due to the water tank capacity, environment, and

difference in run-time when running in robotic mode. A route that takes 45 minutes to teach can take the RoboScrub
20 about 1½ hours to run in robotic mode.

Q: HOW MANY ROUTES CAN I TEACH?

A: You can teach up to 6 routes per home location code. 10 home location codes are provided, so you can teach up to

60 routes total.

Q: WHAT SHOULD I KEEP IN MIND WHEN TEACHING A ROUTE?

A: When teaching a new route, try to make wide graceful turns versus sharp turns or U-turns. Avoid U-turns as much

as possible by circling around an aisle or alternating aisles.

Q: WHEN THE RoboScrub 20 REACHES A POINT WHERE IT IS SUPPOSED TO TURN (OR TURN AROUND), IT STOPS

AND ASKS FOR HELP. IS THERE A MINIMUM SPACE NEEDED TO OPERATE OR TURN AROUND?

A: Think of “3½ - 4½ - 8½”. When your RoboScrub 20 is on a straight path, it can go through spaces as narrow as 3½

feet wide (between two displays for example). When making a turn or going around a corner, it requires a minimum
width of 4½ feet. To make a U-turn, it requires a width of at least 8½ feet.

Q: MY RoboScrub 20 GETS STUCK IN THE SAME PLACE EVERY DAY. THERE IS NOTHING THERE, BUT IT ALWAYS

STOPS AND ASKS FOR HELP. WHAT’S GOING ON?

A: There could be an environmental factor such as a refl ection causing the RoboScrub 20 to think something is

blocking its path. For safety reasons, it errs on the side of caution. If this is a recurrent issue, contact customer
service and provide the home location code number, route letter, area of concern, and pictures of what the RoboScrub
20 sees. In some cases, customer service may be able to remotely adjust the route to improve performance.

Q: HOW DO I PAIR MY PHONE?

A: On the touch screen, select SETTINGS and then NOTIFICATIONS. Use your phone to text the code to the phone

number, as the screen instructs. When successfully paired, you will receive a text message stating that you have been
successfully registered.

Q: I PAIRED MY PHONE YESTERDAY, BUT TODAY I’M NOT RECEIVING ANY ALERTS. WHY?

A: When the RoboScrub 20 is turned off or a different phone is paired, your phone number

will no longer receive alerts. You must pair your phone each day to receive alerts from the
RoboScrub 20. This is to ensure that only an on-site operator will receive alerts.
