Glossary
Power
Rated power consumed by the steam cleaner 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 productivity, 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” steam cleaners, and besides, they load the mains more.
The second point related to power is the calculations of the load on the wiring and various electrical equipment (protective automation, AVRs, generators, etc.).

Steam flow
The steam flow provided by the steam cleaner. For models with power and/or humidity controls, this item indicates the maximum possible value.
When choosing according to this indicator, note that the performance characterizes only the amount of water steam 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. In such comparisons, it is worth assuming that high performance allows to cope with larger volumes of work faster, but requires more powerful heaters and capacious tanks – which, in turn, affects the dimensions, weight and price of the entire steam cleaner.

Boiler tank volume
The volume of the water boiler used in the steam cleaner.
First of all, we emphasize that you should not confuse the boiler and the water tank (see below). A boiler is a tank in which water is heated to form steam; in some models, such a tank is supplemented by a cold water tank, in others, the entire supply of water is located directly in the boiler. Accordingly, the meaning of this parameter depends on whether the unit has an additional tank or not.
If there is a separate tank in the design, then the volume of the boiler is rather a secondary indicator: it is selected in such a way as to provide the claimed performance characteristics, primarily productivity (and it is worth focus on these characteristics when choosing). If there is no tank, then the volume of the boiler directly depends on how much water will fit in the unit and how long it can work on one such “charge”. At the same time, an increase in volume allows you to work longer without refueling, but it affects the dimensions, weight, price, and often also the power consumption of the device (a more capacious boiler requires a more powerful heater).

Continuous operation time
Approximate time that the unit is able to operate without interruption. This parameter is determined primarily by the performance and capacity of the boiler/tank (see above): when the water supply is exhausted, the work will have to pause to replenish the stock. At the same time, for models with humidity and/or power control (also see above), both the average time of continuous operation (at a certain standard mode), and the longest (at minimum intensity) or the shortest (at maximum) can be indicated; these details should be clarified separately.
It is worth saying that some models allow refueling with water right in the process of operation, but it also will be useful to clarify this possibility separately.

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.
Note that the actual heating time may be less than the claimed one. For example, if the main tank is not filled full, 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 characteristics.
