Filtered or non-filtered soymilk maker?

In the process of making soymilk for drinking it, using it as diary replacement in vegan cooking or preparing tofu, one have to strain the mixture to remove the okara. There are lot of soymilk makers available. Some (like the Soyabella) include a filter so that every steps of the process are automatized. Yet, the most recent makers like the Soyapower PLUS are filter-less, which means one have to filter the milk at hand with a strainer.

Why do they removed the filter in the recent soymakers ? Is it to make the cleaning easier, or does it improve the quality to boil the milk together with the okara ?
