The Microsteam 400 Laser soleplate has been designed for optimal steam distribution over it's whole surface, thanks to its 400 micro holes. All Rowenta's soleplates use a high quality stainless steel and have been treated with lasers to compress and harden the surface. The precision shot concentrated at the tip of the soleplate allows you to reach the most difficult areas such as narrow edges, seams and collars for excellent detailed ironing. Thanks to the chromed tip ironing in between buttons and into pockets is made easier. Calc Away System - As the water across much of the UK is very hard, scale can build up and affect the performance of appliances. To combat the problem, Rowenta has developed a patented Technology, the Calc Away system, which attracts scale inside the boiler unit to the anti-calc spoon so it can be collected at the side of the generator for easy disposal. This provides an easy way to deal with hard water and extend the life of your Silence Steam. With the Calc Away system, the frequent maintenance your steam generator is as easy as 1, 2, 3 - 1. Remove the collector; 2. Rinse it under the tap, and 3. Place it back into the appliance. 1.4-litre Water tank capacity. Detachable water tank. Variable steam. Vertical steam. Dry tank alert.
