When choosing the appropriate vacuum across a wide array of available products, it is essential to consider operational features, such as amount of particle removal, ease of filter replacement, and battery life. However, usability and effort required must also be factored in. There are at least three vacuum design features that have ergonomics implications:

1. Weight Distribution – A vacuum design that concentrates its weight (from the battery, dust cup, etc.) closer to the handle will most likely make the vacuum feel lighter and be less fatiguing to use.

2. Handle Angle – Handles that are oriented so that the hand/wrist is mostly in a natural (or “neutral”) posture during vacuum use will also be more comfortable and result in less fatigue while vacuuming.

3. Handle Design – Users intuitively know that their hands are more protected with a “closed” vacuum handle (i.e., one that surrounds the knuckles), so there is less need to hold it tighter than is necessary. This design can also assist in vacuum maneuverability. Compare this with an “open handle” design; here, the user must continually grip it to maintain control of the vacuum and may also grip it more tightly to prevent slippage. This increased effort can also be more fatiguing.
