The waste bin is very small. Do not accumulate waste of carrots for 4 glass of juice. However the product specification says it can remove 2 liters of juice. It may be possible for other fruits which has less waste like oranges, sweet lime etc.
The earlier model HR1855 was very good which had an option to remove the waste bin from behind if its full. This model has disadvantage that whole fitting needs to be opened to remove the waste. I am disappointed with this model as I love carrot juice only. However I m big fan of its old model.
