Question 1

What is the primary reason vacuum cleaner brushrolls should be periodically cleared of hair and fiber?

Accepted Answer

To prevent motor overheating caused by restricted brushroll rotation

Answer

Tangled hair restricts brushroll rotation, which creates motor strain and can cause overheating or belt failure.

Question 2

How should extension cords used with cleaning equipment be stored to prevent damage?

Accepted Answer

Loosely coiled to avoid kinking and stress on wires

Answer

Tight bends and kinks damage the internal wiring insulation, creating fire and shock hazards over time.

Question 3

Which item on a cleaning cart should always have its label visible and legible?

Accepted Answer

All chemical bottles, to ensure correct identification

Answer

Legible labels prevent accidental misuse of chemicals, which could cause surface damage or dangerous chemical reactions.

Question 4

A technician notices a steam cleaner is producing less steam than usual. The most likely cause is:

Mineral deposits from tap water accumulate in the boiler and reduce steam production over time.
