Backpack Vacuums

Overview

Backpack vacuums are regularly used by custodial and housekeeping staff. They are highly mobile units and ideal for use on stairs, walls, ceilings, and smaller areas like elevators and cubicles.

When comparing backpack vacuums, it is important to consider the air watt or airwatt rating - a ratio of the airflow and water lift. The airflow and water lift are measured in cubic feet per minute (CFM) and inches of water (inH2O) respectively. Manufacturers use CFM to convey the strength of a vacuum, a higher CFM will move more air through the unit at a faster rate than a lower CFM unit. Water lift, also known as static pressure refers to the suction force. Airwatts can be expressed in the following formula:

(CFM x inH2O)/8.5 = Airwatt Rating

A backpack vacuum should have about 1600 airwatts in order to achieve a desirable cleaning outcome.

Decision-makers should review the following considerations and are advised to standardize on a single unit.

Space: Area(s) where it will be used. Is the unit appropriate for the size of the space? Will there be tight spaces, obstacles, or furniture to navigate?
Surfaces: Type of flooring/wall/area the unit will be used on. What type of attachments are needed?
Users: The physical characteristics of the end-users. How adaptable is the harness? Is it adaptable to be used by different height/sized users? Harness Fit Guide How heavy is the unit?
Storage: The units will need to be stored somewhere. Is there storage space in an existing custodial closet? Does the unit have a wall mount option?
Portability: Ease by which a user can get the equipment to the job site. Is the unit stored nearby? Does it need to be carried a long-distance?
Maintenance: Ease of changing filters bags/brushes. Is a special tool needed for regular field and daily maintenance?
Power: Access to power. Units can be corded or battery-powered. Are there outlets available? Is the cord long enough? Is the battery capable of lasting the entire shift on a single charge?
Noise and Vibration: Are noise or vibration an issue where the unit will be used? Are equipment operators exposed to hand-arm or whole body vibration?
Testing and Feedback: Demo the product. What was the users’ feedback on the unit after trying in the work environment?

NOTE: Selection of a lower airwatt rated vacuum such as the ProTeam GoFree Flex Pro ll may be appropriate for use in specific work environments or to augment a standard.
