Can you explain this a little further? I've got a shark steamer that I believe has a couple different attachments that could make it useful. Do I just brush then vac the carpet. Then lightly spray cleaner, agitate, steam, and extract? I don't think my extractor is that powerful so am i correct in assuming that also plays big role in the proces.
I also have one specific noob question. When extracting do you pull the trigger to release the liquid as you extract to get better results or does that possibly just end up with you putting too much liquid into the carpets and end up being counter-productive?
You always want to use hot water if possible. Steam is really hot out of a good Italian Steamer, and can burn you with even 3rd degree burns.
Yes, brush in different directions, while vacuuming, looking at what you are doing closely, to determine how much dirt is down at the bottom, and if you are pulling it out.
Spray your cleaner on lightly, but enough to be able to get the carpet damp, not soaked, but damp, so you can then brush it into the fibers of the carpet
Utilize your machine to first vacuum over the area cleaned, then come back over it spraying your hot water into the carpets (pullling the trigger) while it vacuums it out.
Think about this for a second - the faster or slower you run the machine over the area trigger "on", will determine how much water is injected into the carpets. So, you have to decide at that moment, looking at your work there, what is needed next. It is like this with every carpet piece you will ever do.
After awhile it will get easier and faster, but no matter what size of machine, etc., everyone doing this has to make the calculation as they do it.
Looking at your work, do you need to go over it again with more hot water? If so, do it and then no more water. Just vacuum and observe the carpets.
I believe those smaller units have clear plastic nozzles, right? Are you seeing the water coming up into the nozzle? Then you are removing it and need to keep doing that until you are satisfied with the result. Is the carpet cleaner and the spots, dirt, etc., is all gone?
When you run your hand over the extracted carpets, how do they feel to you?
Very damp to wet, you may need to just vacuum more to help remove the soap/water mixture. The more you remove the cleaner, softer, and quicker the entire section will dry.
When in doubt, vacuum more. You want as much of whatever is in the carpets removed from them.
The result will always be cleaner, soft, brighter colored carpet. As it dries the color will also lighten on lighter colored carpets.
Good luck !
