Max Advanced Deep Carpet Cleaner vs Pet TruDeep Cleaner: which is safer?

Where these two actually differ

• We flag Surfactant skin and eye irritation and Residue buildup on carpet fibers on the Rug Doctor and not on the Rug Doctor.
• We flag Bacterial and mold growth in water systems, Motor emissions and particulate inhalation and Plasticizer migration from hose or seal degradation on the Rug Doctor and not on the Rug Doctor.
• The Rug Doctor is Aqueous cleaning solution, surfactants, water where the Rug Doctor is Carpet cleaning machine, plastic/metal/motor components, which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
• We are less certain about the Rug Doctor grade, at 45% confidence against 72%, because it discloses less.
