A credit sweep is a term used to describe a process typically called credit repair.
A credit sweep is a combination of words designed to make you think difficult things are easier than they are. For example, do you want to fix your credit or have it fixed? One of those implies you do it one of those apply someone else does it. Do you want to go through a credit repair process or do you want your credit sweep? One of those sounds like a lot of work and time and energy and money and the other sounds like a click of a button.
A credit sweep doesn’t exist. It simply a marketing gimmick designed by someone who wants to imply credit repair is easier than it is. I should clarify that credit sweeps do not exist legally. There are people who would gain access to the ability to do rapid resource and EOSCAR transactions and will illegally delete items from your credit report. But, this is not only fraudulent but shortsighted. Suppose I can click a button and delete a collection account from your credit report. Well, that creditor will report that item next month anyway; it will pop right back on. The credit sweep, therefore, was useless.
So the answer to your question is that credit sweep is nothing and you should pay no attention. If you’re looking for credit repair, the market is saturated and filled with everything from scammers to people who dedicated their lives to the industry. During your search for credit repair companies, use your brain and user got. If they offer credit sweeps, do not hire them.
