Does Hose Length Affect Vacuum Performance? Real Case Study!

Hose length in vacuum cleaners is one of the most important aspects in determining how much efficiency one will get. If the hose is too long, it will restrict airflow and decrease power. If the hose is too short, it can allow dust to get into the machine, decreasing quality.

There is a lot of debate over how hose length affects vacuum. Some say that as the length of your hose increases, the sucking power decreases; others claim that this is not true. The truth might be found in what type of power source you’re using. Figuring out how to use your vacuum cleaner to its maximum efficiency can be difficult and time-consuming. So, the question remain, does hose length affect vacuum? Let’s find out.

Does Length Of Vacuum Hose Matter?

When it comes to the hose, length matters. After adding 1.5″ crush-proof wide 12.5″ of hose, the CFM decreases by about 7%. This means that after adding three of those hoses, you will lose 21% of suction. The length of the hose above 36″ will impact the suction.

As the hose of a dust extractor gets longer, friction increases. If you compare a 20′ hose to a 10′ hose, you won’t experience too much performance reduction. 

Many people worry that they will lose suction with a longer hose. However, this is not the case. In fact, you may actually gain some suction if you add more length to your vacuum hose. This occurs because there are more paths for the suction hose to take. More paths equal more air that you can vacuum up, increasing the suction of your vacuum cleaner and the amount of dust it is able to pick up!

Will I Lose Suction With A Longer Hose?

Some manufacturers design the hose to be lengthened while retaining function and suction. When a vacuum’s hose is longer, the suction will decrease slightly. 

  • For portable vacuums, length is crucial since they have lower power motors.
  • In contrast, central vacuums have a much more powerful motor. Their size determines how they perform. Changing the hose length does not affect performance. It is important to select the right power unit for your home to ensure maximum suction.

Find the appropriate hose length to go with the vacuum according to the square footage you’ll be working with. A major factor to consider is the water lift. In a home with 2,500 square feet, a rating of 100 to 120 inches is sufficient. In general, higher ratings cover more areas.

How Does Hose Length Affect Vacuum Cleaner Performance?

1. Hose diameter and vacuum efficiency?

Does Hose Diameter Affect Vacuum? Dust extractors tend to use hoses with a diameter of 1-1/2 inches. The smaller diameter hose is easier to coil and handle and more effective. In addition, as your opening diameter decreases, your CFM (air volume) drops, and your water lift (suction power) increases simultaneously.

  • In that case, a smaller diameter hose makes sense if you don’t mind sacrificing some suction area. 
  • Alternatively, a larger hose that draws air in from a larger area makes sense if you’re collecting airborne particles like concrete dust. A bigger motor will increase both.

2. Rigidity and jobsite

No matter where you are, a dust extractor’s performance depends on more than just the length and diameter of its hose. It is also important to how rigid the hose is. 

For example: When you’re working it into tight corners, you drag a hose around. As a result, if you bend the hose over a corner, the airflow will be reduced. On the other hand, rigid hoses are less likely to kink.

3. Vacuum hose connection type and quality

However, even if your hose length, diameter, and rigidity are perfect, the performance may still be poor. This is because any vacuum system will only work correctly if the nozzle is tightly sealed to the motor and vice versa.

The hose connection points from the nozzle and canister to the dust extractor are always imperfect, which causes the air to be drawn in and reduce performance. Sealing these points well will increase the efficiency of your dust extractor.

When Adding Hose Can Be Beneficial?

A longer length of hose is beneficial in several cases.

  1. The first example is in hazardous environments. Despite vacuums exhausting clean air, dust will still settle in your environment. Longer hoses would allow you to place your vacuum in a separate room or area and take less into the workspace.
  2. Second, when it’s not practical to bring your vacuum around. For example, a hose is easier to run in tight spaces, such as attics or crawl spaces, than lifting a vacuum.
  3. Lastly, when you are visiting several locations at once. For example, say you are cleaning up drill slurry from different drilling sites. Again, having more length will be helpful here, as you won’t need to take the vacuum to each location.


The best central vacuum hose is vital to the function of a vacuum cleaner. Without it, there is no way to clean with a vacuum, and our homes would be left dirty and residue-filled. Not only that, but if the hose has a lot of twists and turns in it, the suction is cut-off and less debris will be pulled up into the vacuum. So next time you go shopping for a new vacuum, make sure to check out what kind of hose they have!

Basically, these two points sum up everything. Does hose length affect vacuum efficiency?

  • It is important to remember that shorter hoses are a good option for a more conventional vacuum. If you’re looking for a way to make your life easier, then look no further than a short, convenient hose!
  • While it is true that if you use a powerful motor and maintain a solid connection, the sucking power remains unaffected (little amount of suction power loss). In addition, some areas require long hoses and provide us with a convenient place to work.

Hose Length And Vacuum Performance (FAQs)

What is the difference between a long and short hose?

A long hose is usually covering more area, while a short hose is easier to handle and can be moved around quickly.

What is the length of hose needed for a vacuum cleaner?

The hose length required by your vacuum depends on what you are vacuuming. If you need to reach an area that needs cleaning, then it will make sense to get a long hose. However, if this is not necessary because there are no areas that require cleaning in between rooms or floors (such as vacuuming up dust from the screen door), then short hoses will be sufficient.

What vacuum hose length is suitable for a long hose?

If you want to vacuuming the dust in your closets and stairs, then it would make sense to get longer hoses so that the suction can reach further than normal. Also bear in mind that if there are no areas of cleaning between rooms or floors, then a short hose will suffice (think of vacuuming up any dust from computer equipment or vacuum up any dust and lint from the air vents).

What vacuum hose length is suitable for a short hose?

Here are some of the situations in which it may make sense to get shorter hoses:

1. vacuuming the dust in an area that is limited in size, such as a computer room or bedroom
2. vacuum cleaning on staircases and up from the ground floor to the upper floors
3. vacuum cleaning between rooms without having to go through doorways or pass other walls
4. vacuum cleaning the inside of a small closet or work area

Are there any downsides to using long hoses?

Some disadvantages of longer vacuum hoses include: limited maneuverability (the hose will not easily follow curvy pathways or paths that require twisting), and reduced accessibility when vacuuming in small spaces such as under cabinets or beds.

These drawbacks are offset by the increased suction power of the hose. The length of vacuum hoses is also a factor in versatility and cost, so it’s important to choose the hose size that fits your needs while considering other factors such as suction power requirements.

Does a smaller hose increase suction?

There is no definitive answer to this question as it depends on the specific make and model of hose. In the vacuum hose world, there are two types of suction hose: straight and curved.

Straight suction hoses offer less suction power than curved ones that provide a more flexible path for air to flow through (for example in vacuuming tight spaces such as under beds or behind furniture).

On the other hand, larger diameter design will require longer length of vacuum hose thus they take up more room while being able to produce greater air pressure.

Vacuum hose diameter Vs. its strength?

It depends on the specific application for which the vacuum hose is being used. However, generally speaking, the larger the diameter of a vacuum hose, the greater its strength and capacity.

For the vacuum hose diameter to be greater than one inch, the suction power is inversely proportional with its length. Therefore, if a vacuum hose diameter of 1 inch is long enough for your application (a longer hose makes it easier and more convenient to use in tight spaces) then a 2-1/2-inch diameter will have less suction power by comparison which may not sufficiently meet all of your cleaning needs.
