Polisher & Extractor Equipment Flashcards

What is the primary purpose of using a 'carpet brush agitator' attachment with an extractor?

Answer: To loosen embedded soil before extraction for better results

Agitating carpet fibers before extraction breaks up compacted dirt and lifts it to the surface for more effective vacuuming.

A forced-rotation dual-action (GEX) polisher differs from a free-spinning DA polisher in what key way?

Answer: Its backing plate continues to rotate even under pressure, providing more cutting power

Forced-rotation DAs maintain orbital movement under load, offering more consistent cutting power than free-spinning models that stop under pressure.

Which measurement unit is used to rate an extractor's vacuum motor strength and what does a higher value indicate?

Answer: Inches of water lift — higher value means stronger suction capability

Water lift (inches of Hg) measures how high the vacuum can lift water against gravity, directly indicating suction strength.

When detailing around emblems and trim with a polisher, which technique best prevents product from getting lodged in crevices?

Answer: Apply masking tape over emblems and trim edges before polishing

Masking tape protects trim and emblems from product buildup that is difficult to remove and can cause staining.

What is 'pad seasoning' or 'pad loading,' and how does it affect polishing performance?

Answer: The buildup of dried compound in a pad that reduces its cutting effectiveness

Pad loading occurs when dried compound clogs foam cells, reducing product transfer and cutting efficiency.

For extractor use on leather seats, which water temperature setting is most appropriate?

Answer: Warm water at 100–120°F to loosen soil without drying out leather

Warm water (100–120°F) cleans leather effectively without the heat damage or drying that higher temperatures can cause.

Which type of polisher backing plate material is most commonly used due to its balance of flexibility and durability?

Answer: Velcro-faced flexible foam-core plate

Foam-core Velcro backing plates provide the flexibility to conform to curved panels while securely holding hook-and-loop pads.
