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 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.
Continuous operation time
Approximate time that the device is able to operate without breaks. This parameter is determined primarily by the performance and capacity of the boiler/tank: 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 adjustment, 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 does not hurt 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.
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 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.
