What You Need To Know About Suction Power of A Vacuum Cleaner

Suction power is one of the most important aspects of a vacuum cleaner, playing the biggest role in how much debris it can remove from the floor. But there is more to know about suction, which we’re going to talk about right below.

1. How manufacturers measure suction power

When a manufacturer describes the suction of their vacuums, it may use one of the different measurements.

For example, Shark doesn’t explicitly talk about the suction measurements but instead uses the amperage and wattage ratings for its products, such as the Shark Navigator Lift series. On the other hand, Dyson always puts the attention into the Air Watts specifications. None of those vacuum cleaner ratings, however, are the true indicator of the suction power.

The best way to determine the real suction power of a vacuum is using the Water-Lift test. In this test, the vacuum is connected to an upright tube. Its suction power, measured in inches, is the height of water that it has pulled up.

A stronger vacuum cleaner will make more water travel along the tube, resulting in a higher water column. This means the real unit of suction power should be inches, not Air Watts or amperage ratings.

Besides the Water-Lift test, there are also other ways to test the airflow created by a vacuum cleaner. Other measurements can also provide some valuable information about how powerful a vacuum can be.

For example, you can measure the difference in pressure between the airflow and the atmosphere. The bigger this difference, the more powerful that vacuum cleaner. In this test, the unit indicating the suction is now kPa. Top 10 vacuum cleaners  on the market can deliver a suction of up to 20kPa.

2. How to improve the suction power of your vacuum

You can change the design of your vacuum cleaner, but there are some things you can do to help it reach the maximum suction. This is especially important for old machines. You can start seeing drops in the suction power, and as a result, how much debris and dirt the machine can suck up.

If your vacuum loses its suction power, following this routine to fix the problem.

• Check the dirtbag: see if the dirtbag is full. Even a nearly full bag can reduce the suction power of a vacuum drastically.
• Check the filters: there is often a filter sitting right before the motor to capture dust and dirt, preventing it from going into the motor. Over time there can be a huge buildup of dirt on it, causing the machine to lose suction.
• Check the hose: see if there are any blockages, such as a toy or a pencil inside the hose of your vacuum cleaner. They can get lodged and obstruct the airflow of the vacuum.
• Check for air leakage: this can happen if some of the attachments aren’t fitted properly.

Conclusion

Suction power is what lifts up debris and dirt from the floor into a vacuum cleaner. There are many ways to measure it, depending on the brand you’re using. When your machine gets older, you may notice a drop in suction power. This is true even for  The Best Vacuum Cleaner, but also something you can fix quickly by checking some components of the machine.
