For professional carpet cleaning results, as a minimum we recommend a pump with at least 100psi water pressure. Coupled with a professional vacuum system (to suck the water back out) you can achieve top class professional results with a 100psi pump. Pumps in the 100psi to 150psi range tend to be diaphragm pumps.

A psi setting of 500-100 psi will provide enough pressure to dislodge any particles that may have seeped inside the carpet fibers. Tough stains require a high psi setting, especially if the stain occurs on a light-coloured carpet.

Baking soda helps absorb odors and can be sprinkled on the carpet before vacuuming. White vinegar mixed with water can be used for spot cleaning and removing stains. Additionally, a mixture of dish soap and warm water can work well for general cleaning.

Deep cleaning with a carpet cleaner is by far the easiest and best way to deep clean carpet. A carpet cleaner is a machine that looks like a vacuum but uses water and cleaning solution to do all the hard scrubbing work for you. If you have one, great, if not you can always rent a carpet cleaner or buy one.
