It will hold almost double as many clothes as a normal washing machine. It will however take more water to fill up the tub so it is not as efficient in that respect. This washer is heavier built to handle the weight of larger loads of clothes but operates in the same manner.
I have a Whirlpool Duet, it will hold up to 14 pairs of jeans and 8 bath towels at a wash. I believe it is 4 cubic feet capicity and I feel it depends on what size you get as to how much one of them will hold as far as loads.
