Comparison Tefal Smart Protect Plus FV 6870 vs Tefal Ultragliss Anti-Calc Plus FV 6840

Iron soleplate cover. This surface is in direct contact with the fabric, and therefore the type of coating is one of the most important characteristics.

— Aluminium. Aluminium, being a simple and cost-effective choice, offers advantages such as low weight and rapid heating. However, it is prone to quick scratching, diminishing ironing quality and potentially damaging processed fabrics. Overheating may cause aluminium to stick to fabric, posing cleaning challenges. As a result, "pure" aluminium is often found in the most budget-friendly or compact irons. Some manufacturers employ special technologies in aluminium soleplates to mitigate these drawbacks to some extent.

— Stainless steel. Inexpensive and at the same time very practical material, the most common version of the metal soleplate in modern irons. True to its name, "stainless steel" is highly resistant to corrosion, yet it is durable, free of scratches and burrs, glides well and is easy to clean. Of the significant shortcomings of this material, one can only note a rather large weight.

— Ceramic. The main advantage of ceramics is that it glides much better than steel or aluminium. In addition, this material is easy to clean and practically does not scratch. On the other hand, ceramic soleplates are quite fragile and can break or chip from a strong impact.

— Metal-ceramic. Material generally similar to the ceramics described above; may be somewhat stronger due to the addition of metals, but in fact it all depends on the specific composition.

— Tourmaline. Another type of ceramic material containing tourmaline is a natural semi-precious stone. A feature of tourmaline soleplates is a natural antistatic effect, which is especially useful when ironing light fabrics: such fabrics will not stick to the soleplate due to static charge.

— Titanium/ceramics. Metal-ceramic (see above), which includes titanium. This metal is characterized by high strength and wear resistance, which has a positive effect on the overall reliability of the soleplate.

— Teflon. Teflon (polytetrafluoroethylene) enables smooth gliding of the iron over fabric and offers non-stick properties. This coating is easily cleaned, resists sticking to clothes, and remains relatively clean even in situations like overheating and burning through materials. However, a notable drawback of Teflon is its high sensitivity to scratches, necessitating caution when ironing items with metal buttons, fasteners, or decorative elements.

— Non- stick. This category includes all types of non-teflon non-stick coatings (see above). The specific composition and properties of such a coating may be different. For example, in some models it is the same PTFE, just not called Teflon (the word "Teflon" is a registered trademark and may not be used without permission). In addition, there are other materials. A common feature of all such coatings is that almost no dirt sticks to them, which greatly simplifies the cleaning of the soleplate.

— Titanium. One of the most advanced options. Titanium is extremely durable and virtually unaffected by chips and scratches, even from falls and other serious "accidents". On the other hand, it does not heat up very quickly, but is very expensive. Therefore, such a coating is rare, mainly in premium irons.

— Enamelled. Typically, these soleplates feature a stainless steel base with a specialized enamel coating. The enamel composition is chosen for both smooth gliding and durability. The primary advantage lies in the reliability of this coating, which is highly resistant to scratches—many enameled soleplates can withstand cleaning with metal brushes. However, it's worth noting that irons with such coatings come with a corresponding higher cost.

The steam supply power provided by an iron is essentially the amount of steam supplied by the device per minute. In most modern irons, the intensity of steaming can be adjusted, so this item usually indicates the maximum power value.

The more steam the iron supplies, the more intense the effect on the fabric, the more dense and rigid materials can be effectively smoothed out without resorting to a steam boost (see below). On the other hand, high performance significantly affects the price, dimensions and weight of the iron. Accordingly, it is worth choosing according to this indicator taking into account the planned method of application — especially since the full power of steam is far from always required, and in special cases the same steam boost can be used.

In travel and simple household irons, the productivity is about 15 – 30 g/min. More than 30 g/min corresponds to enhanced steaming, and the most advanced devices, mainly for professional use, are capable of producing 60 g/min or more (the so-called “turbo mode”).

— Steam supply. The possibility of supplying steam to the place of ironing, directly through the soleplate. Steam is effective in smoothing wrinkles, serves various purposes, and offers a bactericidal effect. Contemporary irons commonly offer two steam supply methods: automatic, delivered at a consistent rate, and manual, activated through the "steam boost" mode—providing a brief and potent burst of steam at the touch of a button.

— Vertical steaming. The ability to provide steam in a vertical position of the iron enables a convenient way to "refresh" and smooth clothes directly on the hanger. This proves especially practical for quickly eliminating wrinkles just before dressing and heading out, often surpassing the need for traditional ironing on the board.

— Anti-drip system. An anti-drip feature is essential for preventing water droplets from escaping through the steam holes in the soleplate. Drops can result from iron malfunctions or insufficient temperature during steaming, where water fails to convert to steam in time. These droplets are undesirable as they may cause stains on fabric. Hence, for consistent steaming during regular ironing, the inclusion of an anti-drip system is highly recommended.

— Automatic temperature control. The iron is equipped with an automatic temperature adjustment function tai...lored to the fabric type, be it delicate items or jeans. This feature eliminates the need for manual adjustments on the iron itself, enabling the convenience of ironing everything in a single mode.

— Automatic shutdown. The iron features an automatic power-off function when left stationary for a period. In the horizontal position, where the sole is in contact with fabric or a board, the shutdown time is brief (around 20–30 seconds), minimizing the risk of fabric damage and fires. In the vertical position, the shutdown time can extend to several minutes, allowing users to leave confidently without worrying about the iron turning off.

— Wireless operation. Wireless irons operate independently without a wired connection, facilitated by a specialized stand with contacts and a latch. When heated, the iron rests on the stand, and once the desired temperature is attained, it can be detached. The advantage of wireless models lies in their ability to function in locations where reaching an outlet with a wire is impractical. While periodic placement on the stand is needed to maintain temperature, this is not a significant drawback. Moreover, the stands can be designed to allow the iron to be used conventionally with a cord.

— Eco mode. An energy-saving mode is incorporated, primarily aimed at conserving energy by reducing steam formation intensity. This mode maintains ironing quality through innovative design solutions. However, it's essential to note that the eco mode may not be suitable for all materials; for instance, some irons may restrict its use to wool ironing. Refer to the instructions for specific details.

— Self-cleaning from scale. The automatic descaling function of the iron addresses the issue of limescale, an insoluble deposit that can obstruct pipes and valves in the steam system, reducing efficiency and causing leaks. Furthermore, these deposits may transfer onto treated fabrics. The self-cleaning process typically involves filling the iron with water, heating it to the maximum temperature, and activating the cleaning mode over a sink or container. During this process, hot steam dislodges and expels the scale through the holes in the soleplate of the iron, preventing potential issues.
Automatic cleaning proves particularly beneficial when using hard water, as the hardness salts in the water contribute to scale formation. In addition to self-cleaning, irons may offer alternative methods to combat scale, such as a replaceable cartridge, container, or anti-lime rod, all of which are detailed below.

— Replaceable cartridge. A special cartridge designed to soften the water used and protect the iron from scale. Operating on ion exchange, the cartridge substitutes calcium and magnesium salts (hardness salts) in the water with sodium salts, preventing the formation of insoluble deposits and significantly reducing scale. Despite their efficacy, replaceable cartridges have limitations, requiring periodic replacement due to a finite lifespan. Additionally, they do not offer complete protection against scale; hence, certain models integrate this function with the self-cleaning method described earlier.

— Collector (container) for collecting scale. An alternative scale management method involves a dedicated container that traps insoluble lime deposits. This approach is simple, incurring no extra costs for consumables; periodic removal and rinsing of the container suffice. However, its effectiveness is moderate, as the container only captures scale particles expelled from the iron, offering limited impact on the plaque forming in the steam generation system. Consequently, this function is frequently integrated with other anti-scale solutions like self-cleaning (mentioned earlier) or an anti-lime rod.

— Anti-lime rod. A device designed to prevent limescale formation in the steam supply system takes the form of a specially crafted rod. Composed of a material that selectively attracts calcium salts, the rod ensures that a significant portion of the scale settles on it rather than on the iron's valves, tubes, and other functional components. The rod itself is reusable, requiring periodic removal for sediment cleaning. However, this method only addresses a portion of the scale, typically a substantial one, and is often complemented by a self-cleaning system, as mentioned earlier.

— Cleaning indicator. The presence in the design of the iron of a descaling indicator – against insoluble lime deposits that reduce the efficiency of the steam supply system. The design of such an indication may vary depending on the iron model and manufacturer, but often it is an LED light or some kind of symbol on the control panel - the indicator turns on when the iron needs to be descaled.

— Sound alarm. The presence in the design of the iron of a system that gives sound signals. The specific set of such signals and their application may be different: for example, some models sound the heating up to the operating temperature, others — about auto-shutdown (see above), etc. Anyway, sound notifications allow you to receive signals from the iron even when it is out of sight.

— Display. Own LCD display provides additional information, various notifications about the operation of the iron can be displayed on it: current temperature, steaming mode, warnings about problems, etc. Compared to classic indicator lights, the display is more versatile, but also more expensive.

— Smartphone control. The presence in the iron of the ability to connect to the Internet, as a result of which you can remotely monitor its condition. And the thought of whether I turned off the iron or not will not bother, because at any time this can be done remotely. However, the ability to turn the iron on/off at a distance is the main purpose of this function.

The total weight of the iron. Usually, this parameter is indicated "dry", without water; and for steam generators and ironing systems (see "Type"), the weight of the iron is given, without additional equipment.

Initially, it was believed that the heavier the iron, the more efficiently it performs its task. However, modern models use various technical tricks to achieve good ironing quality with low weight. At the same time, a lighter iron is more “manoeuvrable” and easier to use, you can work with it for a long time without getting tired. Therefore, it makes sense to specifically look for a massive model only in cases where you plan to often work with difficult-to-iron, “unruly” fabrics — for example, natural linen: more weight will give additional processing efficiency.
