What is a wet and dry vacuum cleaner?

Wet and dry vacuum cleaners are machines for trade and industry, as well as the hotel and restaurant trade. They eliminate both dry and damp dirt, including liquids. Commercial wet and dry vacuum cleaners are indispensable for removing coarse and fine dust, particularly for diverse work on building sites or in workshops.

Whether it's for liquids or large amounts of fine dust, they are a cut above normal dry vacuum cleaners for private or commercial use, primarily with regard to the type and amount of contamination that they can eliminate. What's more, the housing, rollers, power cables, etc. meet the demands of daily use in challenging conditions.

Fine dust vacuum cleaners with filter cleaning

Top quality does not happen by accident – it's hard work. Especially on construction sites and in workshops, large quantities of dry dust accumulate, sawdust is generated, material residues fall onto the floor and get stuck in machines. Our fine dust vacuum cleaners are tailored to suit precisely these challenges. The patented Tact filter cleaning technology makes it possible to vacuum large amounts of fine dust without the need for a filter bag. This allows the whole size of the suction container to be used, plus there are no costs for filter bags. Suction power remains consistently high so that you can work at the height of efficiency without interruptions – for both vacuuming directly on the power tool, as well as removing dust deposits.

Our Ap class vacuum cleaners have been designed with semi-automatic filter cleaning for small to medium quantities of fine dust. Of course, they are also brilliant at handling coarse dirt and liquids – a true all-rounder.

Wet vacuum cleaners

Large fluid volumes are difficult to remove without a wet vacuum cleaner. Moisture damages the floor and may cause accidents due to the slipping hazard. These challenges are fun to tackle with our wet vacuum cleaners. Whether you're using them to deep clean floors or remove spilled liquids, it doesn't matter – all of our wet and dry vacuum cleaners eliminate small to large fluid volumes quickly and reliably. If you need a machine primarily for wet vacuum cleaning, our standard class vacuum cleaners are the right choice for you.

Safety vacuum cleaners: easily vacuum harmful substances

Safety vacuum cleaners give you peace of mind. Use them to vacuum hazardous dirt easily – and in the correct way. If you work in an environment with respirable dusts, have anything to do with carcinogenic materials or have even been exposed to asbestos, Kärcher safety vacuum cleaners are your saving grace, allowing you to work in a sustainable and healthy way. Certified flat pleated filters of dust class H keep the vacuumed substances where they should be – inside the vacuum cleaner. Our patented Tact filter cleaning system allows you to vacuum for long periods with powerful suction. When you can easily and safely vacuum up harmful substances, you can concentrate on the important stuff, your work.

How does a Kärcher wet and dry vacuum cleaner work?

In order to cope with the challenging demands required by users on construction sites, in workshops or industry, the Kärcher wet and dry vacuum cleaners offer different functional principles depending on the type of dirt.

A distinction is made between dry and wet contamination, where the specific composition of the dirt plays an important role. Is it coarse-grained or dusty dirt? Does the contamination have a low or high viscosity? There's a Kärcher wet and dry vacuum cleaner to suit dirt of any state, from solid to liquid. 

How it works for wet dirt

The liquid is transported into the container via a suction hose thanks to the bypass blower vacuum generated in the container. To prevent liquids reaching the fan in the event of overfilling, a mechanical float system interrupts the air stream, whereby a float blocks the suction channel or an electronic automatic cutoff switches off the vacuum cleaner.

Mechanical float systems for wet dirt

Mechanical float systems

When the liquid in the container increases, the system pushes the float upwards until it blocks the suction channel, preventing overfilling that would lead to the suction blower being flooded.

Detailed view of electronic float systems

Electronic float systems

If the liquid in the container joins the electrically conductive contacts, the machine switches off to prevent overfilling.


How it works for dry dirt

A vacuum is generated in the container by a bypass blower, which transports dusts inside the container through a hose. As a result, the dirt is separated or filtered through a flat filter or cartridge filter. Over time, dust will clog into the filter, reducing the suction power. To prevent this, there are models with the option of cleaning the filter semi-automatically or fully automatically. For a short period, an air flow is generated that flows through the filter from the clean side, which cleans the filter. Thanks to the design of the suction hose port on the container, the dirt is made to rotate and heavy, coarse particles settle directly on the container floor, like a cyclone.

 

What are the benefits of semi-automatic or fully automatic filter cleaning?

When vacuuming dust without using a filter bag, the filter has to be cleaned regularly to minimise loss of suction power. Many vacuum cleaners have integrated filter cleaning to do this conveniently.

 

Advantages of automatic filter cleaning

  • Consistently high suction power
  • No need to remove the filter
  • No contact with dirt
  • No breathing in dust during filter cleaning
  • No mechanical strain, e.g. from knocking out dirt
  • Work time savings
  • Reduction of incorrect use
  • Cost savings since no filter bags need to be used
  • Making full use of the whole container volume (in contrast to use with a filter bag)
  • This means that the container does not need to be emptied as often

Tact dust class L

Triggered air cleaning technology

On machines in dust class L, the filter cleaning interval for automatic filter cleaning can be set in two stages. At the MIN setting (3), cleaning happens every 60 seconds. At the MAX setting (2), cleaning happens every 15 seconds. When vacuuming liquids or working with filter bags, the Tact function remains switched off (1).

Tact dust class M/H

Triggered air cleaning technology

With automatic filter cleaning, the machine selects the perfect filter cleaning interval itself on machines in dust classes M and H. An electronic differential pressure measurement decides whether cleaning takes places every 7, 15, or 60 seconds, or not at all.

Safety is a matter of Tact

We want to do our bit to protect workers in the construction industry from the dangers of fine dust. So, we've developed a range of vacuum cleaners for removing wet and dry dirt and dust – with the option of vacuuming directly at the dust source thanks to chip and dust suction. We've gone one step further with our latest generation of wet and dry vacuum cleaners in the Tact H and M class.

What does "Tact" stand for? Triggered air cleaning technology

Thanks to a range of functions such as our new, sensor-controlled automatic filter cleaning system (Tact), Kärcher Professional vacuum cleaners and dry vacuum cleaners detect when the flat pleated filter needs cleaning – then they briefly reverse the air flow and blow air through the filter. As a result, users can work without losing any suction power and without any interruptions. This revolutionary system leads to never-seen-before quantities of dust that can be vacuumed without manual filter cleaning, as well as significantly reduced noise if only small amounts of dust are present.

Thanks to this highly efficient filter cleaning, the powerful Tact vacuum cleaners are perfect for both typical and hazardous dusts. The filters have an unparalleled service life – they only need changing after vacuuming 180 kilograms of fine dust (category A mineral dust). As a result, you can enjoy longer periods of uninterrupted work with consistent suction power, as well as better protection against fine dust.

Professional wet and dry vacuum cleaners: dust classes

What do the L, M and H classes stand for?

Dust is a complex mixture of air and solid particles of different shapes and sizes. The chemical composition and physical characteristics may also vary significantly. Dust is categorised into the L, M or H classes using these variables depending on the hazard levels. Fibres, such as the particularly dangerous asbestos and mineral fibres (when < 5 µm), can also penetrate deep into the respiratory tract. The exact identification of the individual dust classes is therefore important in order to be able to select the right vacuum cleaner when the danger has been assessed.

 


L class

Class L vacuum cleaners are particularly suited to vacuuming soft wood, chalk and plaster dust. Dusts in the L class represent a moderate risk. There are no particular precautionary measures for disposing of them.

M class

The L class, upgraded. Suitable for vacuuming dust and dirt generated by the following materials: hardwood, panel materials, paint dust particles, ceramics, concrete and brick. The M class is the lowest legally required class for use on construction sites.

Fine dust on construction sites

Construction dust is a general term to describe the types of dust that typically occur when working in the construction sector. If not properly controlled, the dust types may have serious negative impacts on your breathing and health. The new Kärcher wet and dry vacuum cleaners stand out from the crowd thanks to improved filter technology, which helps to control the dust in your environment, as well as protect you and others from it.

What is construction dust?

Construction dust is a general term to describe the types of dust that typically occur when working in the construction sector. These dusts are more than simply annoying – if not properly controlled, these dust types may seriously harm your breathing and health. Long periods of exposure to some types of dust may cause life-threatening lung illnesses, even leading to death.

We're on familiar ground with fine dust particles that circulate in the atmosphere day to day, such as human skin cells, textile fibres and even particles of burned-up meteorite. However, workers in the construction industry face significantly more hazardous types of dust.

There are three main categories for dust generated during cutting, filing, sanding or any other way of breaking up materials:

Silica dust

Silica dust

Concrete, bricks, tiles, mortar and sandstone (also known as "respirable crystalline silica")

Wood dust

Wood dust

Softwood, hardwood and wood products, such as MDF and plywood

Dusts with low toxicity

Dusts with low toxicity

Plaster (e.g. in plasterboard), limestone, marble and dolomite

Vacuuming up instead of coughing up

Our lungs simply aren't built to deal with fine dust. Let alone large volumes of it. And it's those large volumes that can be extremely dangerous. Chronic lung diseases are therefore number 3 in illness statistics. Treatment costs several billion euros. How much is your health worth to you?

What kind of dust am I breathing in?

  • Silica and asbestos dust are particularly hazardous and may cause cancer.

  • Poisonous or carcinogenic dust from lead, cadmium, vanadium or manganese not only damages your lungs, it also affects other organs like your liver and spleen. This kind of dust is created during welding work among other tasks.

  • Wood dust (such as oak and beech dust) can cause nasal cancer in the long term.

  • Allergenic dust has a plant or animal origin and occurs during cleaning work in or on buildings that are contaminated by bird droppings, for example. Mould spores or microorganisms can also cause allergic reactions.

  • Fibrinogenic dust causes scar tissue to form and progressively changes the composition of your lung tissue after frequent exposure over longer periods. Pneumoconiosis, also know as black lung, caused by quartz and asbestos is one of the most prevalent recognised occupational diseases.

Prevention is always better than a cure

Dust that isn't created in the first place cannot endanger anyone. There are many different ways to prevent dust forming. And if we cannot prevent dust, we can still bind it, vacuum it or block it from entering our lungs with protective clothing and dust masks.

Preventing dust on construction sites using Kärcher wet and dry vacuum cleaners

What can I do to prevent dust?

  • Vacuum dust as soon as it is formed. Many power tools have a port for connecting a vacuum cleaner. Vacuum cleaners with connector sockets turn on automatically when the connected power tool starts up. Always use a suitable filter.

  • Choose low-dust working methods, e.g. wet or damp operation.

  • Bind dust with water, e.g. during demolition work and grinding work outdoors.

  • Use low-dust products, e.g. mortar pellets, ready-mixed concrete and plaster.

  • Avoid stirring up dust unnecessarily. Instead of dry sweeping and using blowers, employ vacuum cleaners and vacuum sweepers.

  • Arrange and take advantage of occupational health screenings.

  • Regularly clean workstations, ventilate work rooms sufficiently, keep work clothes clean.

  • Remove waste immediately and without creating dust.

  • Check the vacuum cleaner's suction performance regularly. Clean or replace the filter as needed. Use vacuum cleaners with automatic filter cleaning for consistently high suction power.

  • Wear protective clothing and dust masks. While used as a matter of course for particularly dusty tasks, you should always wear a suitable dust mask at the very least, even when the dust impact is less severe.
