There are two ways you can go back with the renovator and agitate the carpet and pick up the excess suds.
1. Wait until the tank runs empty then go back, or don't fill the tank so full, so you will have less area to cover before refills.
2. Take the cap off the tank which will stop the suds (you will want the tank below half full for this. Or you can take the tank off, and put the bag back on. (this causes you more steps but works)
In any case you will want to go back over the suds and work them in and pick up the excess. This is where the majority of your cleaning is.
