We had one of these when the children were babies.This new one works just as well as we remember. Turning the handle clockwise mashes and sieves. When the residue in the bowl gets compressed turning the handle anti-clockwise allows it to be re-sieved. Easy peasy. The instuctions advise that the product should be cleaned in warm soapy water, but it doesn't state that it can't be cleaned in a dishwaher. I'll have to ask the supplier.
