NorthStar

Navigation
The NorthStar Navigation Cube acts as a beacon, emitting a signal that
guides Mint Plus’s cleaning.
Connecting to the NorthStar Navigation Cube
Once Mint Plus starts cleaning, it tries to establish a connection to the NorthStar
Navigation Cube, indicated by one flashing blue light on the Navigation System
Indicator. Once Mint Plus has locked onto the Cube, Mint Plus’s lights turn solid
blue.
The Navigation System Indicator also indicates Mint Plus’s range. As Mint Plus 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 Plus may occasionally drive back toward the NorthStar Navigation Cube to
confirm its position before continuing on its cleaning path.
Mint Plus builds a new map each time it starts a new cleaning cycle, but retains its
map if paused during the cleaning cycle.
Cleaning without a NorthStar Navigation Cube:
Because the Cube is just one part of the Navigation System, Mint Plus can still clean
without a NorthStar signal present, however the cleaning area will be much smaller and
Mint Plus will not be able to perform edge cleaning in each section.
Cleaning with multiple NorthStar Navigation Cubes:
Mint Plus can use multiple NorthStar Cubes to extend cleaning coverage up to 2,000
square feet when dry sweeping. Mint Plus will move from one Cube to the next, extending
the cleaning area with each Cube it encounters.
Multiple cubes can be used in Mop mode, too, but Mint Plus limits its wet cleaning area
to 350 square feet to optimize for cloth wetness.
