Ask five people how often carpets need a professional clean and you’ll get five answers. The honest one: for most homes, every 6 to 12 months — but the right number for your home depends on who lives on that carpet.
Move toward every 6 months if…
- You have pets. Hair is the visible part; dander, tracked-in soil and the occasional accident settle deep in the pile where the vacuum can’t reach.
- You have young children. Crawling hands and faces spend more time in contact with carpet than anyone else in the house.
- Anyone has asthma or allergies. Carpet acts like a filter — great at trapping allergens, but like any filter it needs emptying.
- High-traffic areas look darker. Those grey walking lanes are abrasive soil grinding against the fibre with every step. The longer it stays, the more it wears the carpet out.
Once a year is usually fine if…
Adults-only household, shoes off at the door, regular vacuuming, no allergies. An annual deep clean keeps the fibre healthy and the colour true without overdoing it.
Why not just wait until it looks dirty?
Because by the time carpet looks dirty, soil has been cutting away at the fibre for months. Gritty particles act like sandpaper under foot traffic — the wear is permanent even after the dirt is removed. Cleaning on a schedule protects the carpet itself, not just its appearance. It’s also worth checking your carpet’s warranty: many manufacturers require periodic professional cleaning to keep coverage valid.
What about renters?
Your lease may set the schedule for you — many WA tenancy agreements require professional carpet cleaning at the end of the lease, especially where pets have been kept. If a vacate is coming up, see our guide to end of lease cleaning.
The bottom line
Pick the interval that matches your household, put it in the calendar, and the carpet stays genuinely clean instead of cycling between “new” and “needs help”. If you’re in Bunbury or the South West and can’t remember your last professional clean — that usually is the answer.
