medium pile carpet) to about 90 minutes (on hard floor surfaces, where Roomba
doesn't have to work quite as hard).
How many rooms can Roomba clean on a single battery charge?
It depends on the floor surface to be cleaned. For typical operation, Roomba
cleans three 14' x 16' medium-size rooms before the Battery Pack needs to be
recharged.
How long does it take to recharge the Battery Pack?
The Battery Charger that comes with Roomba takes up to 12 hours to recharge
the Battery Pack.
Is there any way to charge the Battery Pack faster than 12 hours?
The Rapid Charger for Roomba can charge a Battery Pack separately in about 2
and a half hours. The Rapid Charger will be available for purchase as of
February 2003. Check back www.roombavac.com for more purchasing details.
How long is the life span of the Battery Pack?
Roomba's Battery Pack should last the life of the machine.
The meaning of the changing colors of the Battery Life Indicator Light
The color of Roomba's Battery Indicator Light tells the amount of charge left in
the Battery Pack, with the following criteria:
GREEN = FULLY CHARGED
AMBER = PARTIALLY CHARGED
RED = ALMOST FULLY DISCHARGED
FLASHING RED = FULLY DISCHARGED
Note: No lights will illuminate on Roomba when it is charging.
General Information about Charging
Roomba's Battery Pack takes about 12 hours to fully charge using the Standard
Charger included with Roomba. Since the Battery Pack is NiMH (nickel-metal-
hydride), there are no issues with battery memory. Thus, you can charge the
Battery Pack either with or without a charge still left in it, and the Battery Pack will
be fine -- It will not lose its "memory" (as can be the case with NiCAD (Nickel
Cadmium) batteries). It is also perfectly okay to leave the Charger plugged into
Roomba indefinitely. The NiMH Battery Pack is also fully disposable in your
regular garbage.
Please note that no lights will illuminate on Roomba when it is charging -- the
only light that is illuminated during charging is the green one on the Charger box
itself. Also, Roomba cannot be activated for use while it is connected to the
Charger.
