There is nothing wrong with cleaning your own carpet with readily available machines you can rent or buy. Bissell and other manufacturers of off the shelf carpet cleaning equipment sell great products that often get the job done between professional carpet cleanings.
A primary tactic is to be sure to not leave any residue in the carpet when your cleaning is completed. Professionals are careful to use neutralizers when rinsing your carpet or simply using very hot water to remove all the alkaline heavy detergents from the fibers.
Another rule of thumb to follow is typically a homeowner would want to cut the recommended soap in half of what is recommended by the manufacturer. Sure, the initial cleaning will look great when introducing that much soap, but my raising the pH so high, it can be difficult to neutralize without proper training.
Furthermore it is always important to run a clean rinse over your carpet after following the manufacturers guidelines. This is help remove any last bit of soap that remained in the carpet. If soap is left in the carpet, then you will notice that it quickly re-soils, requiring you to use the machine over an over just to keep up the appearances of your carpet.
