How Mint Cleans
Mint intelligently cleans your oor by mapping the room as it cleans.
Mint’s Cleaning Cycle
Mint starts by cleaning open areas, cleaning rst to the right and returning later
to clean the area to the left, covering the oor section by section.
When open areas are complete, Mint cleans along edges of furniture and walls
with the side of the cleaning cloth.
When nished, Mint returns to where it started and parks itself.
NorthStar® Navigation
The NorthStar Navigation Cube acts as a beacon, emitting a signal that guides
Mint’s cleaning.
When Mint detects the signal, it tries to establish a connection to the NorthStar
Navigation Cube, indicated by one ashing blue light on the Navigation System
Indicator. Once Mint has locked onto the Cube, the light turns solid blue.
The Navigation System Indicator also indicates Mint’s range. As Mint gets to the edge
of its range (such as going out of the room or far from the NorthStar Navigation Cube)
the number of lights will go down.
Mint may occasionally drive back toward the NorthStar Navigation Cube to conrm
its position before continuing on its cleaning path.
Mint builds a new map each time it starts a new cleaning cycle. Please note that
if you stop or move Mint mid-cycle it will clear its map and create a new one when
you restart it.
Note: Because the Cube is just one part of the NorthStar Navigation System, Mint can still
clean without the Cube present, however the cleaning area will be smaller and Mint will not
be able to perform edge cleaning at the end of the cleaning cycle.
Tip: The rst time you clean, start Mint in an open area to get a sense
of how it maneuvers.
Tip: Use Mint without the NorthStar Cube for a quick clean in small
areas like bathrooms.

PAGE 10
How Mint Cleans Cont’d
Mint’s Moves
In open areas, Mint methodically cleans
back and forth across your oor.
Mint starts where you place it and works
its way out from there, cleaning as far
as it can reliably go and automatically
adjusting to new areas it discovers.
As Mint encounters chair legs, furniture
and other obstacles it cleans around
them and then continues its cleaning
pattern. Mint will periodically return to
areas it skipped before continuing on.
Mint detects stairs and will maneuver
away from drop offs and back to the
cleaning area.
Mint also detects area rugs and raised
transitions to carpet so it can avoid
driving onto them.
Note: If your carpet is flush with your hard surface floor, you may need to add a temporary
barrier to provide Mint a boundary it can detect.
Mint follows along walls and edges as
it encounters them and at the end of its
cleaning cycle.

PAGE 11
Sweep and Mop Modes
Mint sweeps and mops hard surface oors using readily available dry
and wet cleaning cloths or the included reusable microber cloths.
See page 12 for additional information about cleaning cloths.
Sweep Mode
Sweep mode is intended for cleaning with a dry cloth.
In sweep mode, Mint moves ahead in a
straight line when it begins cleaning, then
cleans back and forth in parallel lines.
It is ideal for picking up dust, dirt and
hair to maintain clean, grit-free oors
every day.
Mop Mode
Mop mode is intended for cleaning with a wet cloth.
In mop mode, Mint drives forward a
short distance to one side, backs up
slightly then moves forward to the other
side, alternating to the left and right as
it progresses.
This mopping action helps dissolve
and pick up the deeper dirt and grime
on your oors.
Mint automatically adjusts to a smaller
cleaning area in mop mode to optimize
cleaning while the cloth is wet.
Tip: Start with dry sweep mode to pick up surface grit and then follow
with a wet cloth in mopping mode to get a deeper clean.

Sweep and Mop Modes Cont’d
Cleaning Cloths
Mint is compatible with most disposable dry and pre-moistened wet cleaning cloths
such as Swiffer® brand and store brands like Target®.
Please note that Mint is not compatible with Swiffer® WetJet® Refills.
Microber cloths that are designed to work with Mint can also be used. These cloths
can be rewashed and reused. Different cloths are available for different types of
cleaning. To learn more visit www.mintcleaner.com.
Floor Types
Mint is designed to clean hard surface oors including wood, tile, vinyl,
linoleum and laminate.
Mint cleans best on smooth hard surfaces and may not perform on uneven
tiles, heavily waxed oors or rough surfaces like slate or brick which can snag
the cleaning cloth.
Mint is intended for indoor, household use only.
Mint is not a vacuum and is not intended for use on carpets.
Notice: Mint is not a vacuum and is not intended to pick up large
debris. Pick up large debris before cleaning with Mint and check
for gravel or sharp objects that could scratch the oor if captured
under the cleaning pad.
Notice: Wet cloths may not be suitable for cleaning unsealed
oors. Refer to the instructions included with wet cloths and
solutions to determine if they are safe for your oor.
Tip: Always follow the use and care instructions included with any dry or
wet cleaning cloths to care for your oors.

PAGE 13
Operating Mint
Put On a Cleaning Cloth
Set Mint on its end and remove the
cleaning pad.
Attach a dry or wet cleaning cloth to the
cleaning pad:
Lay the removable pad on an open
cleaning cloth.
Attach cloth by tucking it into the
gripping strips on both sides.
Re-attach the removable cleaning pad.
Magnets will help it snap back into place.
Caution: Make sure the cleaning
cloth does not drape into the middle channel
between the gripping strips as this could
impede sensor functions and safe operation.

Operating Mint Cont’d
Place the NorthStar® Cube
Press the button on the back corner of
the NorthStar Navigation Cube to turn it
on. A blue light will flash on the opposite
corner when turned on, and then go solid
when Mint locks onto it.
If you forget to turn the Cube on, Mint will
send a signal to try to turn it on. If Mint is
successful, the blue flashing light will appear
on the Cube.
Note: You can set up additional Cubes (sold separately) to cover different areas in
your home. If two Cubes are in range, Mint will lock onto the one with the strongest
signal and clean that area. The other Cube will automatically shut off.
Place the NorthStar Navigation Cube on a
table or counter top, pointing the blue light
away from walls and toward the middle of
the room.
For Best Results
Place the NorthStar Navigation Cube where it has a clear view of the ceiling
(for example, no cabinet or shelf directly above it).
Do not move the NorthStar Navigation Cube once Mint has started cleaning
as it may impair Mint’s cleaning performance.
Do not put the NorthStar Navigation Cube on the oor as the cleaner may run
into it and move it.

PAGE 15
Start Cleaning
Place Mint on the oor near the NorthStar Navigation Cube.
Turn Mint on using the power button.
The button will light up blue when the
cleaner is on.
To start cleaning with a DRY CLOTH
just press the Sweep button.
To start cleaning with a WET CLOTH
just press the Mop button.
One blue light will start blinking on the Navigation System Indicator if Mint detects
a signal from the Cube. The light will turn solid blue once it locks onto the Cube.
If no lights appear, Mint does not detect a NorthStar signal.
When Mint nishes cleaning, it plays a short song, returns to where it started
and parks itself. Mint will also do this if the battery runs low while cleaning.
To turn Mint off, press the power button for two seconds. A tune will play and
the light will turn off.
To turn off the NorthStar Navigation Cube, press the button on the back corner.
The light on the opposite corner will turn off.
