THE PROBLEM
On some Roombas, if the main power switch is turned on while the unit is not resting on the ground
and a room size button (S/M/L) is selected, the unit will not begin cleaning, but will instead flash
the Battery Life Indicator Light and S/M/L room size buttons, while emitting a series of six low
buzzes.
Roomba will not operate until the main power switch is turned off and on again with the unit
resting on the ground.
All units will begin cleaning if their main power switch is turned on while they are on the ground.
DIAGNOSIS
Since this non-documented feature may be intermittent, it may not be possible to
duplicate it with any particular unit.
THE SOLUTION
Reassure customer that this is just an undocumented feature, their unit works as intended, and that
they need to remember to turn Roomba's main power switch on only when the unit is on the floor.
