What matters on a carpet job is that the HydroSteam 3618 combines hot water and steam with suction in the same pass. Its SteamWash mode is aimed at tough, oily messes, and the plain Wash mode lets you drop back to cold solution when a rug is delicate. That ability to choose is the most useful safety feature in the group.
It is a portable, so it handles spots, stairs and small rugs, not a whole room. It is also among the pricier handhelds here, since you pay for the maker's support and the mode logic. If your carpet is mostly clean and the problem is a single greasy spill, the cheaper steam units do much the same job.
Test the steam mode in a hidden corner first, because heat can pull dye from some rugs. Nozzle movement should be steady, and follow each steam pass with a dry pass of suction only. Use distilled water in hard water areas to protect the heater from scale. On a greasy spill, blot the excess first, work the SteamWash pass in a small area and extract until the nozzle stops pulling dark water. Many owners keep this model for kitchen and entryway traffic lanes, where oil and dirt bond, and use a cold wash elsewhere.
