Professional vs DIY carpet cleaning: which do you need?
An honest comparison of cleaning a carpet yourself and hiring a professional, including when DIY is plenty and when it can cause problems.
We clean carpets for a living, so you can take our opinion with a pinch of salt. But plenty of jobs genuinely don't need us, and it's useful to know which ones.
When DIY is fine
- Routine upkeep. Nothing replaces regular vacuuming.
- Fresh, small spills. Prompt blotting and a little mild detergent usually sort these out.
- Cheap, washable rugs. Small cotton rugs can often go through a washing machine if the label allows it.
- A light refresh on a robust synthetic carpet, so long as you can dry it well.
Our guide on how to clean a carpet at home walks you through it.
When it's worth hiring someone
- Carpet that hasn't been cleaned in years. The soil is deep, and home equipment won't reach much of it.
- Wool, silk and hand-knotted rugs. Mistakes can be permanent and expensive.
- Pet urine and strong odours. These often need to be dealt with below the surface.
- Old or stubborn stains, especially if you've already tried several products.
- Large areas. A whole office or a few bedrooms is hard work for a small machine.
- Move-out cleaning, when your lease requires it or you'd like a receipt.
The main differences
| DIY | Professional | |
|---|---|---|
| Cost | Low. Products and possibly a machine rental | Higher, but varies a lot by job |
| Suction | Limited, so more water stays in the carpet | Stronger, which means better soil removal and faster drying |
| Depth | Mostly upper pile | Reaches further into the pile |
| Knowledge of fibres | Up to you | Should check fibre and dyes first |
| Risk | Over-wetting, residue, colour damage | Lower, but depends on who you hire |
| Your time | A few hours or more | Mostly just preparing the room |
Why drying tips the balance in Hong Kong
In a dry climate, a damp carpet might dry by itself by evening. Here, it may not. With limited suction, a home machine can leave a carpet damp for a long time, particularly in spring, when humidity is at its highest. That's the point at which DIY can actually cause a problem, with musty smells and conditions that favour mould.
If you're going to do it yourself, choose a dry day, use less water than you think you need, and plan for fans or a dehumidifier.
Five questions to ask a professional
- Which method will you use, and why is it right for this carpet?
- Will you vacuum before washing, and rinse after?
- What's included in the price?
- What are the chances this stain will come out?
- How long will it take to dry?
A cleaner who knows the trade should be happy to answer all of them. You can also see what affects the price in our cost guide.
