Comparison MIOL 82-989 vs Bosch Easy Aquatak 120

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.

Power of the pressure washer motor expressed in watts. Such a designation nowadays is generally accepted for all types of engines; it is quite possible to compare electric and gasoline / diesel units with each other. At the same time, for sinks with internal combustion engines, power in horsepower can also be specified (see above), but most often it is indicated as an addition to watts.

The higher the engine power, the greater the performance and pressure can be achieved at the outlet of the miniwash. On the other hand, this parameter directly affects the cost, as well as fuel / electricity consumption. In addition, in some situations, high power is unnecessary — for example, a delicate surface can be damaged by strong pressure. So when choosing, it is worth considering specific tasks, and not chasing the maximum possible power.

Detailed recommendations on this matter for different cases can be found in special sources. Also note here that most household models (see "Type") have a power of up to 2 kW ( battery units — most often up to 100 W, although there are exceptions). 2 – 3 kW are considered a fairly solid indicator for household sinks, and values \u200b\u200bmore than 3 kW are already found mainly among professional models. Professional equipment, however, is also low-power ( up to 2 kW), but there are few such dev...ices — in general, the power of such units is quite high, in a fairly large number of models it exceeds 4 kW.

Water consumption characterizes productivity, that is, the amount of water that the unit can supply to the nozzle per hour. In most models, performance can be adjusted; for such cases, the characteristics indicate the flow rate at maximum power.

Higher performance allows you to better handle large volumes of work and stubborn dirt, but requires adequate power — and this, in turn, affects the size, price and electricity / fuel consumption. So it is worth choosing according to this parameter, taking into account the features of the planned application. If we talk about specific numbers, then low-capacity washes include models with a rate of up to 350 L / h, which are designed for simple tasks like cleaning windows in a private house, a small car or smaller equipment like bicycles. The unit with a flow rate of 350 – 500 L / h is perfect for washing cars and other similar tasks; if you have to deal with a large car like an SUV, you should pay attention to more performant options — up to 600 L / h. A capacity of 600 L/h or more makes it possible to classify the sink as a professional level, and values of 1000 L/h or more are typical for the most powerful and advanced models that can handle almost any task.

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.

— 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 highest level of noise emitted by the minisink when operating in normal mode. The lower this indicator, the more comfortable the device is to use, the easier it is to use it without special hearing protection; and from certain noise levels the use of protection is mandatory (more on this below). All this is especially true in light of the fact that mini-sinks are quite noisy equipment — even the quietest of these units give out about 60 dB, which is comparable to talking in raised tones at a distance of about 1 m. In the noisiest models, this figure reaches 108 dB — this is comparable to a tractor engine at a distance of the same 1 m.

Recall that the decibel is a non-linear quantity, and it is best to evaluate specific values using comparative tables. Such tables can be found in special sources. Here we note that according to European sanitary standards, noise of 85 dB is allowed to be heard without protective equipment for 8 hours, 91 dB — 2 hours, 97 dB — half an hour, and 103 dB — only 7 minutes. So when choosing a unit, you should take into account the duration of work with it — with high noise, you may need protective headphones.

The length of the power cord provided in the mini washer with an electric motor (see "Motor type"). The longer the cord, the more manoeuvrable the device is, the farther it can be installed from the outlet and the less you will depend on outlets. On the other hand, a long cable can create inconvenience by getting under your feet; however, many mini-washers with this feature provide a winding system (see "Functions and Capabilities") that eliminates this drawback.
