Most homeowners vacuum every week and assume that's enough. Vacuuming is essential — but it only removes what's sitting on top of the fibers. It doesn't touch the dirt, allergens, and residue that settle deeper into the carpet pile over time, which is why carpet manufacturers and cleaning professionals generally recommend a full deep clean on top of regular vacuuming, not instead of it.
A reasonable baseline
As a general guideline, most carpet manufacturers recommend a professional deep clean every 12 to 18 months for an average household. That interval keeps warranties valid on many carpets, too — it's worth checking your carpet's paperwork, since some manufacturers require documented professional cleaning to keep a warranty active.
What shortens the interval
That 12–18 month baseline assumes a fairly average household. A few common factors that mean you'll likely want to clean more often:
Pets. Dander, hair, and the occasional accident all work their way into the pile faster than everyday foot traffic. Homes with dogs or cats often do well on a 6–9 month schedule.
Kids and high foot traffic. Hallways, living rooms, and stairs see more dirt, spills, and wear than a guest bedroom. If your home has a lot of daily movement through carpeted areas, lean toward the shorter end of the range.
Allergies. Carpet fibers trap dust, pollen, and other allergens between cleanings. If anyone in the home deals with allergies or asthma, more frequent deep cleaning can noticeably help indoor air quality.
The St. George factor
Living in the desert adds its own wrinkle. Fine dust gets tracked in from outside more easily here than in a lot of other climates, and it settles into carpet fibers the same way pollen or dander does. If you notice carpets looking dull or your home feels dusty even right after vacuuming, that's usually a sign the fibers need more than a surface pass.
Signs it's time, regardless of the calendar
Timelines are a helpful starting point, but your carpet will usually tell you what it needs. Watch for matting or flattened traffic lanes that vacuuming doesn't lift, lingering odors (especially after a spill or pet accident), visible staining, or a general dullness compared to when the carpet was new.
