Most reviewers report strong results on common set-in stains (mud, wine, tea, pet urine/vomit, and older upholstery marks), especially when using the handheld tools for focused agitation and extraction. One controlled test found upright performance lagged on thicker, greasy food soils like peanut butter, leaving some staining after many passes.

Stain removal is a major strength in the review set, including reports of old pet stains and large colored spills being removed after several passes. Lab-style and hands-on testers generally rate it above average for tough stains, especially when steam pre-treat is used.
