Both upright deep-cleaning machines and compact portable (spot-cleaning) units are commonly used for stairs and other small areas.
Most models use removable clean and dirty-water tanks (separate clean/dirty designs). Capacities in the sample set range from about 23–32 ounces up to 0.5 gallon and 1 gallon, depending on the model.
Cleaning paths range from about 3 inches up to 12 inches. Common widths in the results include 3, 7, 10, 11, and 12 inches.
Power cords commonly range from about 15 to 25 feet, and many machines include a separate cleaning hose roughly 8 feet long for attachments and spot work.
Typical attachments include pet/upholstery tools, small (3-inch) tough-stain or spot tools, crevice/tight-spot tools, detail brushes, and extension or accessory hoses for hard-to-reach areas.
Product descriptions and reviewer summaries report strong stain- and odor-removal performance for pet accidents. Many reviewers praise deep-cleaning effectiveness, and several models highlight enzyme formulas or pet-specific tools for odor elimination.
