Sweep Account to paydown mortgage

[George Smith]

Has anyone here utilized a sweep account to pay down their mortgage quicker? Ive seen only a few articles on the topic, including one's who say there is no difference than paying extra each month or others who offer to sell you software which im not interested in. 

I searched on here and Im surprised that I couldnt find anything on the topic considering that many in the UK use these types of accounts to pay down there mortgage.

Thanks in advance,

George
