1. A system comprising:
a vacuum cleaner having a main body;
a motor-battery assembly configured to removably couple to the main body of the vacuum cleaner, the motor-battery assembly comprising:
a motor-battery housing defining one or more cavities;
a motor-battery assembly suction motor configured to be fluidly coupled to a debris compartment of the vacuum cleaner for generating air flow through the vacuum cleaner for entraining debris, the motor-battery assembly suction motor at least partially disposed within at least one of the one or more cavities;
one or more batteries at least partially disposed within at least one of the one or more cavities; and
a motor/battery controller at least partially disposed within at least one of the one or more cavities, the motor/battery controller configured to control power provided to the motor-battery assembly suction motor and to regulate charging and/or discharging of the one or more batteries;
an alternating current (AC) powered suction motor assembly configured to removably couple to the main body of the vacuum cleaner, the AC powered suction motor assembly comprising:
one or more AC powered suction motors at least partially disposed within an AC motor housing; and
an electrical cord with an electrical plug configured to be electrically coupled to an electrical outlet;
wherein only one of the AC powered suction motor assembly or the motor-battery assembly is coupled to the main body at a time; and
one or more interlocks configured to prevent the motor-battery assembly suction motor from being powered unless the motor-battery assembly is coupled to the main body.
