Forgot some carpet cleaner tips. Th3Batman86 stated, use the hottest water you can. I agree 100%. Not only very hot but use it right away so it doesn't cool down in the machine.
Fro starters; the initial flow of water will be cold to mildly warm so I try and flush it out onto a tray or start cleaning an area that isn't as dirty as the machine won't clean as well with cooler solution. For the
hand wand, I do the same.
When done I rinse the reservoirs, and flush the suction sections by vacuuming up water. There will be water remaining in the lines so simply operate the trigger with no water in the reservoir to flush or it out.
As soap is corrosive, not doing this will generate problems. Make sure everything is dry before storing the unit.
The machine doesn't do a large ares at all. I can't give you an exact figure other than it may do one very small room.
With all said and done, with your time, proper machine care, the money invested and limited carpet cleaning knowledge, it may be less aggravating and produce better results to hire a pro that has top notch
equipment and a good reputation.
