Power consumption
Rated power consumed by the device during operation. Usually, it is indicated by the maximum power consumption when used in normal mode, without abnormal situations.
In general, this parameter is secondary when choosing: manufacturers select power in such a way as to provide the necessary indicators of performance, pressure, etc. However, some practical points are also associated with power. So, with the same performance (see "Steam intensity"), a more powerful device will spend less time heating water and generating steam; it can also be provided with a more capacious boiler (see "Water boiler volume"), which is useful for long-term continuous operation. On the other hand, such devices turn out to be more expensive, and often also heavier and larger than relatively “weak” steamers, and besides, they load the mains more.
The second point related to power is just the calculations of the load on the wiring and various electrical equipment (protective automation, AVRs, generators, etc.).
Water tank volume
The volume of the tank for the water supply provided in the device.
We emphasize that this indicator should not be confused with the volume of the boiler (see above): in this case, we are talking about a reservoir with a supply of cold water, from which such water enters the boiler for heating. Not every steam cleaner is equipped with such a reservoir.
Detachable water tank
Device has a water tank with a
detachable design.
The detachable design makes refueling much easier. In particular, it allows to fill the tank under the tap, while with a non-detachable tank, this option is often not available. And some models with this feature can be refueled during operation, without turning off the heating and without relieving pressure in the boiler (although it still will be necessary to clarify this possibility separately). In addition, a detachable tank is much easier to clean or wash than a non-detachable one.
Steam power adjustment
A controller that changes the power of the steam coming from the device, in other words, the overall speed and flow rate at the outlet. Do not confuse this feature with humidity adjustment: the change in power is carried out mainly by changing the operating pressure, while the humidity may remain unchanged (and vice versa).
Steamers with power adjustment can be easily adjusted to the specifics of the situation, choosing the optimal mode depending on the tasks and materials.
Steam flow
Steam flow provided by the device. For models with power and/or humidity adjustment, this item indicates the maximum possible value.
When choosing according to this indicator, it should be borne in mind that the steam flow characterizes only the amount of water vapor produced by the device per minute. The intensity of the impact of this steam on the treated surface/product can be different, first of all, it depends on the working pressure. Therefore, only devices with similar pressure indicators can be directly compared by this indicator. When making these comparisons, it's worth assuming that higher steam flow allows to handle a large amount of work faster, but requires more powerful heaters and larger tanks – which, in turn, affects the dimensions, weight and price of the entire steamer.
Heating time
Heating time until steam is generated. The duration of the heating process directly depends on the power of the device and the volume of the water tank.
We also note that in some situations the actual heating time may be less than the declared one. For example, if the main tank (boiler) is not completely filled, and the design does not provide an additional tank for cold water. For a full guarantee, you should still focus on the value directly stated in the specifications.
Power cord rewind
The possibility of
power cord rewind on a special object installed directly on (in) the body of the steamer. This ensures at least additional convenience in storage/transportation — the power cord does not interfere during operation.
Note that for winding, a special coil is most often used — like those that are installed, for example, in vacuum cleaners. To unwind the wire from such a coil, you need to pull it, and the winding occurs automatically at the touch of a button. At the same time, the power cord does not have to be pulled out completely — you can choose the length so that it is guaranteed to reach the socket and at the same time does not create inconvenience. This provides additional comfort during work.
Steam hose length
The length of the steam supply hose included with the steamer.
The longer the hose, the farther you can reach without moving the device itself. On the other hand, a large length can create inconvenience during storage and transportation, as well as when working at short distances.
Power cord length
The length of the cable with which the device is connected to the mains. The longer the power cord — the farther from the socket the device can operate, the more freedom of movement the user has. On the other hand, an unnecessarily long cord can create difficulties both during operation and in storage/transportation; and when working away from the socket, you can use an extension cord.
