How Mint Cleans
Mint intelligently cleans your floor by mapping the room as it cleans.
Mint’s Cleaning Cycle
Mint starts by cleaning open areas, cleaning first to the right and returning later
to clean the area to the left, covering the floor section by section.
When open areas are complete, Mint cleans along edges of furniture and walls
with the side of the cleaning cloth.
When finished, 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 flashing 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 confirm
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 first 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.
