Comparison AL-KO Easy Flex PW2040 vs Tekhmann PWC-2025

The maximum outlet water pressure provided by the miniwash; for models in which the pressure is not regulated, this paragraph indicates the standard operating value.

The higher the water pressure at the outlet, the more efficiently the unit handles with chronic and stubborn contaminants. On the other hand, strong pressure requires high engine power, which affects the dimensions, weight and price of the device — despite the fact that not every dirt requires such pressure, and excessively intensive washing can damage the surface to be treated. Thus, the pressure is chosen by manufacturers in accordance with the general class of the miniwash. Thus, values up to 100 bar are found in the most compact and low-power domestic models (see "Type"). A pressure of 100 – 125 bar is considered relatively low for household sinks, and most of these models are in the range of 125 – 150 bar — this is most often quite enough, taking into account the characteristics of the application. For professional units, the average is considered to be 150 – 175 barhowever, there are many models that give out more than 175 bar.

The highest inlet water temperature allowed by the design of the mini-sink.

For some tasks, warm or even hot water is the best option. And devices that allow the connection of warm water may have different restrictions on its temperature. So if the ability to work with hot water is important to you, you should pay special attention to the maximum allowable temperature: it should be at least 60 °C. And ideally, the limit should be at least 80 °C.

Note that many mini-sinks have their own built-in heaters (see "Water heating"); while some of these models also allow external connection of hot water, others work only with cold water.

The length of the high pressure hose that connects the gun to the washer body.

The larger this length, the more freedom of movement the user has. On the other hand, a hose that is too long can be inconvenient when working at short distances. Therefore, when choosing, you should not chase the maximum length of the hose, but take into account the real conditions in which you plan to work. The best method for choosing a hose length is to estimate the maximum distance to be removed from the sink body, and add a margin of at least 2 to 3 metres to it in case of unforeseen circumstances (for example, obstacles that prevent the hose from being pulled directly).

The shortest HP hoses in modern mini-sinks are up to 4 m long, in the longest this figure can exceed 10 m. However, the most popular are the average values — 4 – 6 m and 6 – 10 m.

— Pressure adjustment. Possibility of adjusting the output pressure - the intensity of the water jet. Choosing the optimal pressure force allows you to effectively use the sink to clean various types of surfaces. So, for more delicate surfaces such as car body or painted walls, you can set the pressure level to a low level in order to avoid damage to sensitive surfaces. And for durable materials such as concrete paths or stone walls, it is preferable to use higher pressure - thereby effectively removing stubborn contaminants.

- Vacuum cleaner. The sink can be used as a traditional vacuum cleaner to collect dust and small debris. Moreover, many models with this function also have a blower mode, which allows you to use a stream of air not to draw in, but to sweep away contaminants; this can be important, for example, when clearing a lawn or garden path of fallen leaves. In any case, a vacuum cleaner makes it possible to first remove excess dirt from the surface that it would be undesirable to wash away with a powerful stream of water. On the other hand, such equipment significantly affects the price, weight and dimensions of the entire sink - despite the fact that it is not required so often (and even in cases where it is required, it can be easier and more reasonable to use a traditional vacuum cleaner). Therefore, very few sinks with this function are produced.

...- Drum. The presence of a drum (reel) for a high-pressure hose in a mini-washer provides additional convenience not only in storage/transportation, but also during operation: the hose can be easily unwound before starting work and reeled in at the end, and the actual length of the hose can be adjusted by simply unwinding the required amount from the drum.

— Wheels for transportation. Such wheels are especially useful given the fact that modern mini-washes (especially powerful and productive ones) can be quite heavy and bulky. Most often, the design provides for one pair of wheels - thus, in a vertical position, the support on the opposite side of the body acts as a parking brake, and to move the unit you need to tilt it slightly.

— Taking water from the tank. A function that allows the mini-wash to use water from open containers - a bucket, barrel, tank, or even a natural body of water such as a pond or river. Taking water from a container can be a real lifesaver if there is no running water nearby or it is impossible to connect to it.

- Container for water. The sink has its own water tank. As a result, the unit does not depend on the water supply or external water containers; its mobility is limited only by the power cord (and battery-powered models are generally completely autonomous). On the other hand, your own tank significantly affects the dimensions and weight, and the need for it arises relatively rarely - even in the absence of running water, it is more convenient to use an external container.

— Water heating. Hot water is better at removing many contaminants than cold water; In addition, in winter it is also useful for melting ice. But not all sinks can boast a connection to hot water, which is why built-in heating systems are provided. Most often, a furnace running on liquid fuel is responsible for heating, even if the sink itself runs on electricity.

— Container for chemicals (foam). This function should not be confused with a foam generator attachment (see “Attachments”): the foam container is a separate tank for collecting detergent and can be used in combination with any attachment - for example, a brush or dirt cutter. On the other hand, the quality of the foam is somewhat lower than when using a separate foam generator.

— Collection of chemicals from the container. The presence of a foam generator in the design of the sink, which allows you to make foam with any nozzle (as in the paragraph “Container for chemicals” described above). The key difference is the absence of a tank, and a tube for collecting chemicals is removed from the device.

— Water filter. The presence of a water filter in the design of the mini-wash. In some models, the filtration system may be multi-stage. Specific details for each model must be clarified separately. However, in any case, it is worth keeping in mind that the filtration system affects the cost of the unit and requires regular maintenance: filters need to be cleaned from time to time, and sometimes replaced.

— Built-in pressure gauge. This function is found mainly in powerful professional solutions. The pressure gauge allows you to carefully control the pressure, selecting it depending on the current tasks; This is especially true when processing delicate surfaces that can be damaged by excessively high pressure.

- Overheat protection. A safety system that protects the mini washer motor from heat that can lead to damage. When the critical temperature is reached, the engine automatically turns off; You can start the device again only after it has cooled down sufficiently and the overheating protection has not tripped.

— Water cooling of the engine. Units with such a cooling system use water to remove heat from the electric motor. It is pumped directly around the hot components of the power unit, thereby ensuring effective heat absorption. Washers with an engine water cooling system can be used in long-term and continuous operation without the risk of motor overheating.

The name of the battery platform supported by the implement.

A battery platform is a battery standard used to ensure that different appliances of the same brand (power tools, pressure washers, flashlights ...) can use the same power sources and chargers for them. This eliminates the need to use a different battery and “charger” for each individual device, and also makes it easier to find compatible power sources: instead of checking a list of compatible batteries, you just need to make sure that the battery you select is from a supported platform. (However, models of compatible batteries can also be specified in the specifications — see below for more details).

Batteries of the same platform mainly differ from each other in terms of capacity — and, accordingly, cost.

Nominal voltage of the battery used in the washer with the corresponding type of power supply (see "Power supply"). For models not originally equipped with batteries (see "Complete battery"), this paragraph indicates the voltage for which the device is designed.

Theoretically, a higher voltage allows you to achieve more power, but there is no strict dependence here, and models of similar power can differ markedly in this parameter. And when looking for a spare or replacement battery for a unit with a removable battery, you should focus not on voltage, but first of all on compatible batteries directly stated in the specifications (see below) or a battery platform (see above). So, in general, this characteristic is more of a reference than practically significant, and when choosing it, you can not pay much attention to it.

Model of the battery supplied with the unit.

This information is specified mainly for models supplied with one removable battery (see "Complete battery"). Knowing the model of this battery, if desired, you can find detailed information on it and evaluate its suitability for certain tasks. This feature can be especially useful in cases where there is not quite a standard use — for example, numerous charge-discharge cycles in a row, or operation at low temperatures. In addition, we recall that sinks with removable batteries usually use standard batteries that are also suitable for some other equipment of the same brand (primarily power tools). Accordingly, the data on the model of this battery makes it possible to evaluate which devices it will still fit. And if the characteristics of the unit do not specify models of compatible batteries (see below), then information about the complete battery will also be useful when looking for replacement / spare power sources.

Battery models that the washer of the corresponding type is compatible with. This information will be useful in cases where the battery(ies) must be purchased separately, for example, if the tool does not come with a battery at all, if you need to supplement the original package, or if the existing battery has failed.

Note that in addition to this information, the characteristics may also specify the name of the battery platform — the general standard of power sources that the unit complies with (for more details, see above). However, if possible, you should still focus on a specific list of compatible batteries — this will give the maximum guarantee that there will be no problems with the energy source.
