Machine without any friction is an ideal machine so an ideal machine cannot have friction.
In ideal machine input is equal to output . The efficiency of ideal machine is 100% . In real machine input is not equal to output .The efficiency of ideal machine in not 100% . In ideal machine there is no lose of energy . In real machine there is lose of energy . In real machine there is no friction . While in real machine there is friction .
A real machine is like an ideal machine in that there are no massless chains or frictionless bearings. The parts of an ideal machine are rigid and weightless.
No, there is not such thing as an ideal machine; it's just an idea.
An ideal machine can reach 100% efficiency as there is no friction or other restraints involved, whereas a real machine can never reach 100% efficiency.

No physical machine is ideal. Friction is always a loss of energy.
In an ideal frictionless system, the work input equals the output and force. Your Welcome!!!

Ideal Mechanical Advantage (IMA)
If you have a large washing machine, they do just fine in one. Usually a commercial one works better than a home one.
No heat loss = maximum output. There would be no loss of energy, which is an ideal condition.
