Pretty Good Shorty,
It also keeps the seam flat and will pull adhesive into the backing causing a better bonding.
It will also help if you have a wet seam to put together, such as opening a carpet after a water damage job. Sometimes one needs to open the carpet and there is no seam, so you cut the face and open the carpet. Maybe you want to spot weld the carpet to keep it together until you are ready to put in new pad or whatever is needed. With the Kool
Glide and SDN you can make a seam with the damp carpet.
The SDN is also good to use for some spotting work. If you have a 'spot' of some sort and you use your spotter and you are concerned with wicking or just want to pull up as much as possible, you can put a towel over the spot and put the SDN over the spot and let it pull the last little residue into the towel by just leaving the SDN on the area while you do something else, (this is to replace the times when you would put a towel over a wicking spot and weight it down). You can also use it to dry out a small area spot by just putting it over the spot and allowing it to dry it out. I have used it this way on several urine spots on sisal, kept it laying flat and dried it out.
It is rather unique in you can put it onto a very wet carpet and it will vacuum the water but not hurt the unit since the vacuums are protected from getting wet.
Pretty neat tool. Yes I know we have water claws and I do also and use them as the principle tool for such work but at times it is nice to had the SDN if I do not have other tools with me and a spot needs to be cared for and I want to have the wicking pulled up into a towel. Just sharing another interesting use for the tool.
Primarily, it is used to cool a seam, keep it flat and pull the adhesive into the backing of the carpet. Great little tool to have and use.
