More and more people in Poland are buying pressure washers for their homes. With their help, it is much easier and faster to remove dirt from various surfaces: cars, facades, roofs or paving stones. It is a very effective method, provided the appropriate nozzle is used. Choosing the high-pressure washer itself is also not easy. This is mainly due to the wealth of models on the market. So how do you choose the model best suited to your needs? Find out how a pressure washer is built and how it works!
How does a pressure washer work?
The operation of a high-pressure washer resembles the work of a compressor. The main element is the drive in the form of an electric motor or (in some professional models) an internal combustion engine. This drives a pump that forces water into the high-pressure hose. Every pressure washer also has a lance connected to the end of that hose. It allows you to properly direct the high-pressure water jet, which is released when the trigger is pressed. The appropriate nozzle for a pressure washer makes it easier to wash different surfaces. It is a replaceable element, so with one washer you can clean paving stones, as well as a car or a roof.As a rule, a pressure washer for home use is slightly smaller. It also provides lower pressure. However, the main difference between professional models and those for household use is operating time. The former can run continuously for several hours without the risk of components overheating.
Construction of a pressure washer
When choosing the model best suited to your needs, it is worth paying attention to the detailed construction of the pressure washer:
Type of drive. For household applications, electric motor washers are mainly used. They are quieter and lighter. Combustion engine models, on the other hand, do not require access to the power grid. They also have higher power. For this reason they are often part of company equipment.
A key parameter of pressure washers is the generated pressure. It can reach values from 110 bar for household devices to even 300 bar in models intended for firms.
The high-pressure hose is usually about five metres long. Thanks to this you do not have to drag the whole unit with you. Such a length of high-pressure hose does not affect the water pressure. Some models are equipped with an additional detergent feeder, which makes it easier to clean heavily dried-on dirt.
It is worth paying extra attention to the pressure washer gun. Sometimes you can find pressure switches and controls for changing other operating parameters on them. In this way you can adjust the water stream to your needs at any time, without the need to return to the pressure washer.
Additional equipment. Nozzles in the lance can be replaced with other tips that facilitate performing certain specific tasks. A good example is the pressure washer brush, designed for cleaning paving stones. It has several nozzles directed downward that also rotate around a common axis. In this way, removing even the most stubborn dirt becomes much easier.
The construction of individual pressure washer models can differ in many details. Therefore it is always worth carefully analysing the available solutions: many of them may prove to be created with our needs in mind.
How to use a pressure washer?
One of the key elements of a pressure washer is the nozzle. Depending on its shape and functionality, the direction of the water stream can be different. That is why different nozzles for a pressure washer are used for certain jobs.
A rotary nozzle is set in rotational motion by the pressure of the flowing water. It is useful for washing large surfaces, such as a driveway paved with paving stones.
A sandblasting nozzle has an additional sand feeder. This way metal elements are cleaned of rust and other deep contaminants.
A pipe-cleaning nozzle will work in the case of a clogged sewer. It is mounted on a flexible high-pressure hose.
An adjustable-angle nozzle allows better adaptation of the angle (width) of the water stream. Thanks to the ability to adjust the angle of the water stream, this nozzle is ideal for cleaning various surfaces, such as sidewalks, terraces, building facades, vehicles and garden furniture.
Two-stage or three-stage nozzles allow changing the water pressure depending on needs.
Additionally, a hot-water pressure washer has a built-in heater to remove the most stubborn dirt using temperature.
Accessories for pressure washers
To make use of all the possibilities a pressure washer offers, it is worth equipping yourself with additional accessories. This will make it easier to clean various surfaces even from heavily dried dirt and dust. The lance of a pressure washer is constructed so that at any moment it is possible to change the tip to a different type. For example, a pressure washer for paving stones is equipped with a special brush with rotating nozzles.Various types of attachments for a pressure washer are not the only accessories worth having. An additional feature of many models is also a detergent tank. This makes it possible to create active foam and better clean the washed surface, for example a vehicle body. Larger pressure washers also have a reel for winding the garden hose and a special quick coupler ½’’.
Which pressure washer to buy for the home, garden and beyond
Looking for the best solution, you are certainly wondering, which pressure washer for the home will be optimal? Be sure to pay attention to details such as the material from which individual components are made. A plastic pump for a pressure washer can quickly become damaged and require repair. A much better solution is an aluminium pump. However, components made of brass demonstrate the highest durability. The same applies to the motor that a pressure washer has. How to choose the best one? Avoid cheaper and weak materials such as plastics, and opt for the most durable: aluminium, steel and brass.Will a smallpressure washer 120 bar work at home? It is a handy device, equipped with additional wheels and a long, five-metre high-pressure hose. Thanks to this, the comfort of working with this washer is at the highest level. Such a pressure level is sufficient for most household tasks. An advantage of the mentioned model is a small terrace-cleaning brush that was included in the set.
Applications of a pressure washer: how can it be used?
The applications of pressure washers are much broader than washing a terrace or a facade. Appropriate pressure washer brushes make it easier to remove even the toughest dirt, for example on vehicles used in companies. If you run your own business or have even a small fleet of trucks or construction vehicles, you should opt for a stronger solution. An ideal choice is thepressure washer 180 bar. It comes with additional tips in the set and a large brush for cleaning paving stones (for example from oil stains or other dirt left by vehicles).With intensive use of such devices, it is worth remembering to service them properly. The pressure washer filter should be regularly replaced or cleaned to protect all the washer's components. This way you can extend the period of trouble-free operation and thus reduce operating costs.
Which parameters should you pay attention to when choosing a pressure washer?
When wondering which pressure washer will be the best, you cannot omit the most important parameters of these devices. One of the key values for washers is, of course, the height of the pressure that can be achieved in the high-pressure hose. However, this is not the only important value on the product sheet that deserves careful attention.When buying a washer, you should check the engine parameters, such as its power. The power supply is also important: 230 V or 400 V (the common industrial supply). So which pressure washer to buy? Preferably one with as powerful an engine as possible. Models for home use are designed in the range from 1200 to 1600 W. Suchpressure washers can be found in our online store. With such power, all pressure washer parts will work well with the purchased model. In the case of professional washers, there are also internal combustion engines powered by petrol or diesel. These usually achieve much higher power ranges.Another group of important parameters is the water flow. The nominal flow, given in litres per minute, specifies the water usage when the lance is operating. The overall flow, given in litres per hour, indicates what the water consumption will be during operation. The more water is pumped, the stronger the water jet we obtain – cleaning will be even easier. For household pressure washers it most often ranges from 400 to 1000 litres per hour.
Car warning vest should be in every vehicle – in case of a breakdown it will allow the driver standing next to the vehicle to remain visible even after dark. However high-visibility vests are also an essential piece of equipment for construction workers, road workers and many other jobs. Check what to consider when buying a warning vest!
Is a warning vest mandatory?
A warning vest is an inexpensive item of clothing that everyone should have. It is useful not only in the car, but also when cycling after dark or even as protection for a pedestrian walking on the roadside.
Do you have to have a warning vest in the car? Polish regulations do not impose such a requirement on drivers. They indicate, among other things, the need to have a reflective triangle and a fire extinguisher. Although you won't get a fine for not having a warning vest, it is definitely worth having one. If you often travel with passengers, it's best to equip yourself with reflective vests in quantities sufficient to provide visibility to passengers if needed.
Reflective warning vest – a requirement in many professions
While a high-visibility vest for a motorcycle, bicycle or car is not required by regulations, in some professions it is. Professional high-visibility clothing is a necessary part of the wardrobe for airport workers, heavy equipment operators, construction workers, and people performing official duties on roads or in railway areas.
As for warning vests, regulations in 2023 require them to be one of three colors: yellow, orange or red. In addition to fluorescent colors, they must also have reflective elements.
High-visibility clothing is divided into class one, two and three. In the case of warning vests only classes one and two are possible, because class three requires reflectors on the sleeves or trouser legs. Such a standard is met, for example, by warning jackets.
A class one high-visibility vest must have 0.14 m2 of fluorescent background, while the total area of reflective elements must be 0.10 m2. For class two these values are 0.50 m2 and 0.13 m2 respectively. A professional class 2 vest is ORLA Warning Vest. Available in two colors – orange and yellow, it meets EU standards EN ISO 20471 and EN ISO 13688. Two reflective strips 5 cm wide provide visibility, and the anatomical fit guarantees comfort of use of the reflective warning vest both during work duties and while traveling by bike, motorcycle or on foot.
Summer and winter warning vest to suit your needs
When choosing a reflective warning vest for pedestrians, cyclists or motorcyclists, pay particular attention to its size and the quality of the material. Contrary to appearances, fit is very important – especially if you will be wearing the vest for a long time. This type of body-protecting clothing is available in standard sizes – from S to 3XL. Importantly, these products are not divided into men's and women's high-visibility vests – they are universal garments with a simple cut.
In cold months, an insulated work warning vest will provide protection against cold, wind and precipitation. The REMS insulated warning vest model has a warm inner layer. An additional convenience is a zipper closure instead of traditional Velcro. This solution allows better protection against low temperatures and weather conditions. The REMS warning vest also has two inner pockets that allow for storing accessories useful at work.
How much does a reflective warning vest cost?
Purchasing a reflective PPE vest will not usually ruin the household budget of someone who wants to be visible while cycling or to have such important protection in the car.
You can also find much cheaper products in stores and at online auctions. Do yellow and orange reflective vests for 4–5 PLN differ from those from a trusted manufacturer costing a dozen or so zlotys? Although they may look the same at first glance, you will notice the difference in how long the product lasts. The reflective warning material on high-quality vests is much more durable – it retains its shape after many wash cycles. Meanwhile, cheap reflective vests often lose their properties after just 2–3 washes.
So if you don't want to spend two years wearing a vest that has never been washed, choose a higher-class product. Quality matters especially when you buy reflective warning PPE vests for your employees.
Of course you'll pay more for an insulated warning vest with pockets. For the aforementioned REMS model you'll pay 166 PLN. In this case, however, you should particularly take quality into account. A vest of poor quality, made of non-breathable material, will cause significant discomfort during work. It is definitely better to opt for products from a trusted warning vest manufacturer.Author: Paweł Sokołowski
WHAT IS THE CE MARK?
The CE marking (Conformité Européenne) is the European conformity mark. Its use on a product's packaging indicates that the manufacturer has applied and fulfilled the relevant requirements contained in European directives/regulations, as well as in the European standards covering the product. A product that meets safety requirements will be marked with the CE mark, thereby informing the user that it is safe and has been properly placed on the market.WHY WAS IT INTRODUCED?
After the European Union removed trade barriers between Member States and established a common policy toward partner countries outside the EU, an area of free movement of goods was created within the Community. However, the main barrier to trade remained national requirements concerning, for example, the quality and safety of products. The national systems of regulations and standards used by countries often differed significantly from one another. This caused a range of problems for manufacturers who, in order to sell their product in different countries, had to meet separate requirements each time.
Because consumer safety could not be compromised by eliminating standards, the only solution was to harmonize national systems so that goods would be subject to the same requirements throughout the Community.
In 1993, European legal acts called NEW APPROACH DIRECTIVES were created at EU level. They defined essential safety requirements for different groups of products that must be met before they can be placed on the market or put into service on the Single European Market.
IS CE MARKING MANDATORY OR VOLUNTARY?
if a product falls under one of the New Approach Directives, CE marking is mandatory.
applying CE marking to products that are not subject to the New Approach Directives is prohibited.
WHO CAN AFFIX THE CE MARK?
CE marking may be affixed by the manufacturer or their authorized representative. Most products fall under Module A, i.e., the manufacturer's self-assessment module. If another module applies (B or D), an EU type-examination certificate must be obtained in cooperation with a notified body (a certifying institute).
WHAT IS A CE CERTIFICATE?
The term "CE certificate" does not exist in the nomenclature of the New Approach directives. If someone talks about a CE certificate, they most likely mean the EU declaration of conformity or the EU type-examination certificate confirming the product's conformity with the relevant EN standard.
Currently, the process of marking and certification is regulated by Regulation (EU) 2016/425 of the European Parliament and of the Council of 9 March 2016 on personal protective equipment and repealing Council Directive 89/686/EEC.

In 2022 as many as 66,606 occupational accidents were reported in Poland. 365 of the injured suffered very serious injuries, and the number of fatal accidents amounted to 180. In almost 80% the lower or upper limbs were injured. Among the most common causes was contact with a stationary or moving object. These data clearly indicate how important it is to provide employees with appropriate protective clothing.
Differences between protective clothing and workwear
To begin with, it is worth dispelling an important mistake. The term „occupational protective clothing (PPE)” and “workwear” are often used interchangeably. However, they do not mean the same thing. To fully answer this question, it is useful to know the exact definitions of both concepts.
Definition of workwear and protective clothing
Workwear is clothing used in the workplace when there is a high risk of soiling or damaging outer garments. In other words, workwear replaces the employee’s clothing in situations where it may become dirty or ruined while performing duties. The use of uniform work outfits may also be related to building brand recognition (e.g., bank or insurance company employees).
And what is protective clothing? The definition states that it is clothing used in the workplace that is intended to cover or replace personal clothing. In addition, it is designed to provide protection against hazards. Both conditions must be met, so workwear that does not protect against specific dangerous substances or events is not protective clothing.
Applications of workwear and protective clothing
When is protective clothing used? Examples of such situations can be found in every industry. It is most often used by employees on production floors and those working in the field, and its purpose is to protect against impacts and cuts (such as protective boots with a steel toe cap). There is also protective clothing for welding and heavy aprons for laboratory technicians who come into contact with hazardous substances.
Work clothes are used even more frequently. They can be found in organizations that care about brand recognition linked to employee attire. Work uniforms are also widely used in the catering industry.
Types of protective and work clothing
Any clothing can be divided according to the part of the wardrobe it represents: protective or work gloves, trousers, jackets, boots or vests. It is worth paying more attention to the classification of protective clothing depending on the hazard it is meant to protect against. In this context, one can list:
Protective clothing for welders, protecting against electric arc, burns and splatter.
Harnesses related to working at heights.
Insulating protective clothing, used by electricians.
High-visibility clothing, protecting road workers, as well as emergency services operating at the scene of a road accident.
Chemical protective clothing, resistant to short-term exposure to hazardous corrosive substances.
Protective earmuffs that protect against excessively loud equipment noise.
Flame-resistant protective clothing for firefighters and people working near open flames.
Additionally, categories of protective clothing may also concern seasons, such as winter and summer protective clothing.
Protective clothing markings
Types of protective clothing can also be characterized by the areas of the body they are meant to protect.
Protective clothing (symbol U).
Lower limb protection (symbol N).
Upper limb protection (symbol R).
Head protection (symbol G).
Face and eye protection (symbol T).
Hearing protection (symbol S).
Respiratory protection (symbol D).
Protection against falls from height (symbol W).
Full body insulating protection (symbol I).
So how to choose the appropriate protective and work clothing for your workplace? That is always the employer’s responsibility!
Employer's obligations regarding protective and work clothing
Under current labor regulations, the employer is obliged to provide the employee free of charge with workwear, protective clothing and personal protective equipment (PPE) if required by the working conditions. Importantly, the decisive factor is the conditions prevailing in a given work environment, not, for example, the job title. For this reason, employees in similar positions at different companies may receive a different set of clothing.
Protective clothing is the employer's obligation
The employer must determine what professional workwear and protective clothing are needed for each employee. This usually takes place during a dialogue with employees or their representative. These arrangements are then entered into the work regulations, which define the conditions for being in the workplace, as well as equipping employees with tools, materials, protective and work clothing and personal and hygiene protective equipment. Typically the details are presented as a protective clothing allocation table for each position.
Work clothing and footwear provided by the employer
Work and protective clothing are provided free of charge. At the same time, they remain the property of the employer. This means that upon termination of employment, all personal protective equipment and allocated clothing must be returned to the supervisor. Also, in the event of clothing being destroyed due to the employee’s fault, reimbursement of the purchase costs is required (after accounting for depreciation).
Employer's duties regarding employee safety
The employer’s duties related to protective clothing and workwear also include cleaning, maintenance, repair, dust removal and disinfection. However, employees often wash their work clothes themselves. In such cases they are entitled to reimbursement of the costs they incur.
Standards and certifications of workwear and protective clothing
Workwear does not require certification, because its primary task is to protect personal clothing from dirt or damage. However, specialist protective clothing for workers must meet specific standards and criteria in order to effectively protect against hazards in the workplace.
Clothing materials: what determines their protective properties?
Protective garments are made from natural materials (cotton), regenerated (cellulose-based) and synthetic materials (polyester or polyamide). From these, several dozen popular materials with specific properties have been developed. Among them you can find:
Ortalion made from polyester. It is characterized by very low weight and high resistance to damage.
Fleece, a soft and warm polyester knit.
Stretch, i.e. stretch fabrics with added Lycra or PBT.
Corduroy, a warm cotton fabric resistant to cuts and tears, but prone to abrasion.
Ballistic nylon, also used in the production of bulletproof vests. It is very resistant to damage and abrasion.
Kevlar, an elastic material that is also extremely durable.
The choice of the appropriate material depends on the work environment and the conducted occupational risk analysis.
Certification by EN ISO standards: what does it mean for protective clothing?
In Poland, EU Regulation No. 2016/425 of 16 March currently applies. It specifies a number of standards for particular types of protective and specialized clothing. It is there that the exact parameters that protective clothing for firefighters, welders and other positions must meet are defined.
All protective garments must also have certificates confirming compliance with the above standards. To obtain them, clothing undergoes rigorous laboratory tests, which must then be repeated at regular intervals.
Summary: protective and work clothing
There are still many workplace accidents in Poland. To provide employees with the best possible protection, protective clothing and personal protective equipment are used in accordance with the protective clothing allocation table. Each such garment must meet protective clothing standards, confirming protection against hazards in the working environment.
In many positions, an employee also receives workwear that protects personal clothing from damage or soiling. In this case, there is no need to obtain certifications.
Both workwear and protective clothing belong to the employer, who should care for them: clean, repair and maintain them.Author: Grzegorz Nowak
