I have used both fully as well as semi-automatic washing machine.
Well, first of all, I would say that if u r short of time and cannot attend machine then simply go for fully automatic one.It will cost u more than triple amount but its worth.
Of course , that semi automatic washing machine needs to be attended...that is .
.on the water tap...
fill the drum upto required level... close the tap ...etc
I mean to say u have to manually attend to each of its function...wash , rinse..wash, rinse, and
finally remooooove all the clothes from one drum and put them in spin tub for drying.
Now the plus point in semi-automatic is that u can complete a wash in short time also, as it is operated manually .actually it is ideal for a family where varied kind of washing is needed...that is for eg. few white clothes, , and one delicate frilly frock or a sari and aheavy towel and one jeans..etc.
Naturally u cannot dump delicate clothes with jeans in a fully automatic machine....
also it is not economical plus such along time to run two cycles of fully automatic machine....
therefore before buying which type ...consider your personal requirement.. type of cothes that go in one load, cost factor, time factor, etc
