Quick Answer: Yes, You Must Vacuum
YES. Removes 79% of insoluble dry soil before water touches the fibers. If you wet un-vacuumed carpet, you essentially create mud at the base of your carpet, leading to poor results and wick-back staining.
Did You Know?
Professional Hot Water Extraction (Steam Cleaning) is designed to remove oils and sticky soils that vacuums can't. It is NOT designed to act as a vacuum cleaner. Asking a wet cleaner to do dry soil removal is inefficient and ineffective.
The Science: 79% is Dry Soil
According to the NCCA (National Carpet Cleaners Association), up to 79% of the soil in your carpet is dry particulate matter. This includes:
Skin Cells
Microscopic flakes shed by humans and pets daily.
Grit & Sand
Sharp particles that cut fibers like glass when walked on.
Insoluble
Does not dissolve in water; naturally falls to the base.
Because this soil is insoluble, water won't dissolve it. It just turns it into a wet paste. Vacuuming removes it mechanically when it is dry and loose, which is far easier than trying to wash it out.
The "Mud Principle"
Imagine throwing a bucket of water on a dusty driveway. Does it clean it? No, it creates mud. The exact same thing happens in your carpet.
Dust + Water = MudWhen professional cleaners inject water at 400-800 PSI, if that dry soil hasn't been removed, the pressure forces it down into the backing of the carpet. As the carpet dries, this "mud" wicks back up to the tips of the fibers, creating brown patches or a grey, dull appearance.
Beyond Vacuuming: Pile Lifting
At Blowup Cleaners, we don't just vacuum. We use industrial pile lifters (like the CRB - Counter Rotating Brush machine).
Why Pile Lifting Matches Premium Results
- Opens the Fibers: Matted carpet prevents water from reaching deep. Lifting fibers opens pathways for cleaning solution.
- Digs Deep: Standard vacuums clean the top 1/3rd. Pile lifters dig out hair and grit from the base.
- Pre-Agitation: It helps work the pre-spray into the carpet for better chemical action.

Budget Cleaners (£25/room)
- Rely on YOU to vacuum
- Rush the job (in and out)
- Skip pile lifting completely
- Risk making mud/sludge
Premium Cleaners (Blowup)
- Industrial HEPA Vacuum included
- Use CRB Pile Lifters
- Edge detail vacuuming
- Guarantee dry soil removal
How to Vacuum for a Deep Clean
If you are preparing for a cleaner who doesn't vacuum, or just maintaining your carpets, follow these steps:
Move Small Items
Get toys, shoes, and small tables off the floor. Give yourself clear lanes.
Check the Bag/Filter
A vacuum loses 50% suction if the bag is 2/3 full. Start empty.
Slow Down
The backward stroke cleans; the forward stroke positions. Move at half your normal speed.
Cross Pattern
Vacuum North-South, then East-West. This lifts fibers from all angles.
What Our Customers Say
Sarah Jenkins
Altrincham, Manchester
"I didn't realize how much dust was in my carpet until they used their industrial vacuum. The difference before they even started washing was incredible!"
Deep Clean & Stain Removal
Mike Thompson
Stockport
"Other cleaners I've used just sprayed water instantly. These guys spent 20 minutes just vacuuming and lifting the pile first. The result speaks for itself."
