DIY Wet Vac

A common problem with cold plate refrigeration is frost buildup. There are few options for removing the frost. One is to shutdown the system until it melts, not practical for a live aboard. Another is to scrape it into the bottom of the freezer, this just changes the problem. To solve this new one you need a way to get the frost(snow) out of the bottom so it does not form a glacier. One could use a shop-vac but those are big and do not store well.

Our solution was US$2.40 of bilge hose attached to a gallon water jug and our rechargeable vacuum the Dyson DC35. It work perfectly removing about a 1/2 gallon of frost.
