There is now more choice than ever before when you come to choose a carpet cleaning machine, but it can make the decision difficult.
2 of the most popular types of machine are the box/spray-extract machines and the brush/self-contained machines. They are both great choices for different senarios, but one of the first decisions you need to make is the type of machine you are after.
How they Work
Spray-extract or box extractor carpet cleaning machines have a solution tank and a dirty water tank. The water is pumped from the solution tank to the upholstery tool, or carpet wand then extracted through the wand and vacuum hose to the recovery tank. The size varies from tub vacuum sized machines up to 50L capacity machines.
Brush/self-contained carpet cleaning machines have a solution tank and dirty water tank. The water is pumped from the solution tank to the brushes. The brush agitates the pile of the carpet and the vacuum bar vacuums the dirty water into the recovery tank. The size varies from Rug Doctor size, to large walk behind machines.
The best machine for you entirely depends on the application.
Generally if you are doing a lot of larger commercial jobs, then the brush machine is the obvoius choice because it can clean large areas much quicker. The added benefit with a brush machine is that the brush agitates the pile of the carpet and makes the clean more effective, and will clean in a single pass. The pile of the carpet looks great after cleaning it too!
Brush machines are also known as 'self-contained' machines. Because everything is self-contained there are no hoses etc to trip over. That said, most machine will have the option to attach a hose to, for upholstery and getting into the edges and awkward areas.
Box-extractors are very versatile, and if you get a good enough size machine you can join 2 sets of hoses up together and leave the machine downstairs whilst you clean upstairs (look out for a machine with 150psi pump and at least 2 vacuums to be able to do this - read more about PSI here). These machines get into much smaller spaces, so ideal if you are doing a lot of domestic or mixed application jobs.
