Max. inlet water temperature

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.

Features

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.

Brushless motor

The presence of an induction (brushless) motor in an electrically powered sink (see "Power Source").

Such a motor differs from more popular collector electric motors primarily in that its design does not have a collector with brushes — a set of moving contacts responsible for switching the current on the windings when the rotor rotates. Instead, such switching is carried out by built-in electronic circuits. This design provides a number of advantages. One of the main ones is high efficiency, due to which, with the same power consumption, such an engine provides greater productivity and pressure at the outlet of the sink. In addition, the absence of unnecessary moving and rubbing parts reduces wear and heat, thus positively affecting reliability and durability; and the absence of sparks (which often occur in the collector) makes such engines also as fireproof as possible. The downside of all these advantages is a rather high price and difficulty in repair. Thus, brushless motors are mainly equipped with professional-grade units designed for long-term use at high loads.
