We cannot find the HLP21E model on Haier official website at this moment. There are only 2 models: HLP21N and HLP23E listed there if you choose the category “washer” and use the filter “compact washers”.
However, according to the info we get, the only difference between Haier HLP21N and HLP21E is: the HLP21N equipped with casters that allows you to move it around easier while the HLP21E does not include. Otherwise, they are the same.
If you know any difference between these Haier portable washing machine, please share below.
