CCT Cleaning Methods & Equipment Usage 4

Question 1

Absorbent compound cleaning uses a moist, absorbent carrier material. After working it into the carpet, how is the compound and soil removed?

Accepted Answer

Vacuuming with a commercial upright or canister vacuum

Answer

Once the absorbent compound dries with the soil absorbed into it, thorough vacuuming removes the compound along with the trapped soil.

Question 2

Which equipment component on a truck-mount converts engine power into vacuum and water pressure?

Accepted Answer

Blower (vacuum producer) and pump assembly

Answer

The blower generates vacuum lift while the high-pressure pump drives water through the system; both are typically powered directly by the vehicle engine or a separate power unit.

Question 3

When cleaning stairs with a portable unit, which practice minimizes the risk of overwetting?

Accepted Answer

Make multiple wet passes followed by a single dry extraction pass

Answer

Multiple wet passes followed by dedicated dry extraction strokes ensures maximum moisture removal from the thinner stair tread, reducing drying time and overwetting risk.

Question 4

What is the function of a water softener installed on a truck-mount system?

Accepted Answer

It removes minerals that reduce chemical effectiveness and cause scale buildup

Answer

Hard water minerals (calcium, magnesium) interfere with detergent performance and deposit scale in hoses and heat exchangers; a water softener removes these minerals.

Question 5

A rotary extractor (RX-20 style) should NOT be used on which carpet type?

Accepted Answer

High-pile shag or frieze carpet

Answer

The spinning heads of a rotary extractor can tangle and mat high-pile shag or frieze fibers, causing severe damage that is difficult or impossible to reverse.
