We compare the advantages and disadvantages of different types of industrial vacuum cleaner and answer your most important questions regarding general information and purchase.




Summary

  • Industrial vacuum cleaner are multi-functional cleaning devices that are mainly used in large-scale industry, as they are far more powerful than conventional domestic hoovers.
  • A rough distinction is made between wet-dry vacuum cleaners with dust bags and without dust bags, which are to be preferred depending on the intended use.
  • Before buying a professional device, it is important to pay attention to weight and size, suction capacity, cable and hose length, capacity and the legally specified filter classes.

The Best Industrial Vacuum Cleaner: Our Choices

Industrial vacuum cleaner: buying and evaluation criteria

Before you start buying an industrial vacuum cleaner, you need to know exactly what requirements you or your industry have for your machine. Based on these criteria, you can compare industrial vacuum cleaner with each other:

In the following, we will take a closer look at the criteria and explain exactly what you need to look out for.

Filter classes

In order to prevent injuries and guarantee hygiene, there are very strict requirements regarding the filters of hoovers in the trade. These are based on the respective dust classes that the devices meet.

  1. Dust class L: Class L covers slightly hazardous dust. This includes normal house dust, lime, gypsum, sand and the like. There are no special requirements for disposal.
  2. Dust class M: Class M hoovers are used for medium hazardous dust. This includes wood and metal dusts as well as particles of paint. You should dispose of the filters with as little dust as possible.
  3. Dust class H: Only class H hoovers are suitable for highly hazardous dust materials. These are usually very hazardous to health! They include fine dusts such as lead dust, mineral fibres, asbestos, mould spores and also highly explosive liquids. Make sure that you dispose of them absolutely dust-free.

Check the TRGS 504 (Technical Rules for Hazardous Substances) to find out which class your dust product belongs to! At this point, the ATEX directives (legal basis for explosion protection) must also be taken into account.

Absorption capacity

Find out about the vacuum power of the model. The vacuum is specified in Pascal (Pa) or in millimetres of water column (10 Pascal ≈ 1 millimetre of water column). The powerful models can reach up to 3,000 millimetres of water column.

Especially if you need an H-class hoover, you must control the speed of the air flow in the suction hose. In this class it must not be less than 20 metres per second!

The suction power is influenced by the quality and condition of the filters, the filling level of the dust bag and the motor power (Watt). The energy consumption of most industrial vacuum cleaner is between 1,000 and 4,000 watts.

Bear in mind that a higher power rating also means a higher noise level (decibels). For orientation: 50 decibels is below normal speech volume; 85 decibels is in the range that can cause permanent hearing damage! In this case, units with double soundproofing are recommended.

Cable and hose length

Depending on the radius of action you want to ensure, you should pay attention to the length of the cable and the hose.

Long cables are particularly useful when working on large areas. At this point you can also use extension cables and cable reels.

If you have to clean very angled surfaces, you should choose a model with a long hose. Make sure that the hose does not exceed a length of 10 metres, otherwise the suction power will be impaired!

Container volume

Depending on the intended use, you will need industrial vacuum cleaner with different volumes. The more volume your tank vacuum cleaner has, the less often you will have to empty it.

If you work in a small workshop, a container with a capacity of 15 litres is often sufficient. Most models used in industry have a capacity of 20 to 30 litres. If you need a larger volume, it is best to talk to your supplier individually.

In general: With a larger collection container, you can use your appliance even more flexibly and need to empty it less often.

Connection for other electrical appliances

Such devices are particularly useful in craft workshops. With some models, additional electronic devices can be connected to the machine's own socket.

This saves you the mess of extension cords!

Tip: With some industrial vacuum cleaner, you can use the hose as a perfect link to grinders. The falling chips are then sucked up without any problems and the workplace remains clean!

Size and weight

Before buying the tool, it is useful to know how much mobility is needed. Does it have to be light enough to be lifted into a car and small enough to be stowed in the cargo area?

Choose the hoover according to its working environment.

Standard industrial vacuum cleaner range in weight from 8 to 12 kilograms and have wheels on their base so they are easy to transport. Some even have a handle, making them more comfortable to carry.

However, there are also special models for large-scale industry that can be classified in much higher weight classes. These can be ride-on units with a tare weight of around 500 to 600 kilograms.

Industrial vacuum cleaner: frequently asked questions and answers

So that you are familiar with the essential facts about industrial vacuum cleaner, we have selected the most important questions and will answer them briefly.

What is an industrial vacuum cleaner?

An industrial vacuum cleaner, also known as a kettle hoover, is basically very similar to a normal house hoover. They both have the basic function of removing dirt from surfaces. But the differences become apparent in their scope of application.

If the home is only to be freed from annoying dust, the conventional hoovers are absolutely sufficient.

But if it's about business, you'll encounter conditions of a tougher calibre and you'll need one thing above all else. More. More power. More robustness. More efficiency. More features.

Industrial vacuum cleaners are true all-rounders when it comes to removing dirt. The multi-purpose vacuums easily take on dirt, metal and wood chips as well as liquids. Many can even be converted into pumps and (leaf) blowers.

This means they outperform their domestic counterparts in terms of versatility by quite a bit, even though the basic design and mode of operation are not that different.

In addition to the greater variety of functions, however, the industrial vacuum cleaner are larger, much more robust, have a stronger suction capacity and larger container volumes. The professional devices are also bound by strict specifications, especially with regard to the filters.

How does an industrial vacuum cleaner work?

Vessel vacuums basically have the same technology in the background. Inside the cylindrical housing there is a motor or a battery that generates a vacuum.

The resulting draught ensures that dust, liquids and the like are sucked in and pass through the hose into the interior.

The suction power can be regulated there by a so-called triac regulator in which the current flow angle can be adjusted with a variable resistor.

Unlike industrial vacuum cleaner with bags, bagless ones are usually odourless. However, the collection container must be cleaned thoroughly after each use! Otherwise, dirt will remain in this model too long and spread odours.

There are special water filters for wet vacuuming, which must also be emptied regularly, otherwise mould will form.

What are the possible uses for industrial vacuum cleaner?

The multi-purpose vacuum cleaners are also versatile according to their versatile functions. The use of an industrial vacuum cleaner is suitable:

  • at home
  • in the workshop and on the building site
  • as well as in large-scale industry.

At home

Of course, the all-rounder hoovers are not limited to commercial use. In addition to normal vacuuming, they can also prove to be a helpful tool in your own four walls.

A glass on the table falls over, the beautiful vase of flowers is knocked over or rainwater including mud is carried into the house. Now a burst pipe and a flooded cellar. Will a normal hoover be able to clean that up? Hardly.

Workshop and building site

For master craftsmen, industrial vacuum cleaner are extremely useful in the workshop. With many models, you can connect the hose to a grinder, for example, so that the falling chips are immediately sucked up.

Metal chips can be produced when working with metals. To avoid injuries and damage to the product, the chips should be removed properly with an industrial vacuum cleaner. (Image source: Patrick Grüterich / Pixabay)

In addition, you will often find a separate socket on the machine to which other electronic tools can be connected.

Industrial operation

In industry, quality and safety are among the top priorities. When you work with metal, there will be chips that can cause damage to the workpiece and other machines.

To ensure that the product and the machine retain their value, many companies use compressed air guns or even hand brooms.

Professional cleaning has a positive impact on the workplace and the bottom line.

Why? It is cheap. The consequence? The chips are spread instead of removed and the problem is exacerbated. Because the dirt is also harmful to the health of the employees when chips get into the eyes or respiratory tract, for example, and lead to injuries.

The keyword hygiene must be observed especially in the food industry. The equipment used must always be disinfected and free of disturbing particles.

Fine dusts must be removed immediately so that an explosion risk can be avoided.

The solution is to use industrial vacuum cleaner, which are guaranteed to remove particles more efficiently, cleanly and conveniently.

What types of industrial vacuum cleaner are there?

Industrial vacuum cleaner are roughly divided into two different types:

type advantages disadvantages
Industrial vacuum cleaner with dust bag Easy and hygienic cleaning as well as separation of dust and liquids Wet vacuuming is not possible with the bag. Sharp-edged stones etc. can damage the bag. Procurement of bags can be cost-intensive.
Industrial vacuum cleaner without dust bag No bag that can tear. No costs due to repurchase of bags. Wet vacuuming is possible without problems More effort as the container has to be cleaned again after each use. Less hygiene during cleaning.

Wet vacuuming is only possible with a model with a bag if the bag is removed manually before vacuuming. Before reinserting the bag, you must thoroughly clean and dry the container after wet use.

How much does an industrial vacuum cleaner cost?

Be aware here: private or commercial use? Prices can vary greatly depending on the intended use and filter class.

Use Price
Office and private use Approx. 50 to 450 €
Industrial use Approximately €500 to six figures

Since the price range is very wide, you should seek extensive advice on the respective models if you are planning to make a major investment.

What are the alternatives to an industrial vacuum cleaner?

Depending on the intended use, there may be different alternatives to industrial vacuum cleaner:

Alternative Description
Normal hoover Depending on the size of the surfaces to be cleaned in the household or office, a conventional hoover may be perfectly adequate. The extra functions of an industrial vacuum cleaner are rarely needed here.
Water pump If, for example, a pond needs to be pumped out or the entire cellar is full of water, it is better to use a water pump. The amount of water would exceed the capacity of an industrial vacuum cleaner and you would mainly be busy emptying the water tank.
Leaf blower The industrial vacuum cleaner is very suitable for blowing away dry leaves. However, the blowing power should not be overestimated. If the leaves are wet, stuck together or lying in mud, it is better to use a leaf blower.

In the commercial sector, however, there is no alternative to a professional industrial vacuum cleaner. Only these devices are legally approved and comply with hygiene and safety regulations.

How do I clean an industrial vacuum cleaner?

To benefit from the best possible suction power of the devices, you should follow these 5 care instructions:

  1. Observe manufacturer's instructions: Familiarise yourself with the operating instructions before operating your industrial vacuum cleaner and adhere to the specifications.
  2. Regular maintenance: Regularly check the general functions of your machine. This includes routine bag and filter checks. Make sure that the bags and containers used are not damaged and are correctly inserted. Also check the filters and remove any excess fibres that may be clogging the filters.
    Change the bags and filters regularly. For the filters, this is usually every two years at the latest and the bags before they are completely full.
  3. Avoiding chemicals: Make sure that you do not suck up any chemicals with the hoover and that you do not use any for cleaning! Regardless of the material the vacuum cleaner is made of, these substances will attack the high-quality appliance and make it porous. This not only reduces performance, but also service life.
  4. Regular cleaning: If the hoover is exposed to external dirt, you should wipe it down with a damp cloth from time to time. Mild detergents and warm water are sufficient for cleaning. At this point, also consider the nozzles and the pipes of the vacuum cleaner. The nozzles can be cleaned with your hands or a brush. The pipes should be soaked for an hour in a warm water bath with a little washing-up liquid for optimal care. Rinse them well afterwards and let them dry.
  5. Dry storage: When the unit is not in use, place it in a dry place and cover it with a tarpaulin if necessary.

Conclusion

Industrial vacuum cleaner offer you more. More than a conventional hoover can do. They are made for the tougher challenges of cleaning surfaces and are therefore far more powerful.

In this article, we have introduced you to the best industrial vacuum cleaner currently available. Of course, which one is perfect for you depends on where and what you want to use it for. We have therefore shown you the basic types of industrial vacuum cleaner.

It is important that you go through the criteria before you buy and check whether the model meets them. If it does, you'll have a highly efficient cleaner that can handle even the toughest conditions.
