Choose a steam generator if you regularly iron large piles of laundry, particularly linen, heavyweight cotton or difficult fabrics, and have room to store its base. A good steam iron is often the better choice for shorter sessions. For longer ironing sessions, focus on comparing the exact model’s runtime, filling process and descaling procedure.
If you regularly iron a substantial pile of clothes, household linen or shirts and can set aside space for the base, a steam generator could be a worthwhile choice. Make sure its runtime and maintenance requirements suit your routine. According to Que Choisir, a steam generator is particularly well suited to ironing large quantities.
Linen, heavyweight cotton, denim and some mixed fabrics may require several passes with an iron. According to Que Choisir, the benefits of a steam generator are more noticeable on these fabrics than on everyday laundry.
If cupboard space is limited or you only iron a few items at a time, a compact steam iron may be easier to take out, set up and put away. A steam generator has a bulkier base, even if its iron feels lighter in your hand.
| Priority | What to check | Your needs |
|---|---|---|
| Crease removal | Compare the steam output and test results on several fabrics. Treat the steam boost as an extra feature for stubborn creases, rather than confusing it with continuous steam output. | I want to avoid making multiple passes over linen, heavyweight cotton or denim. Que Choisir distinguishes between measuring steam output and assessing crease removal on different fabrics. |
| Size and manoeuvrability | Measure the space for the base in your cupboard and on your ironing board. Check the weight of the iron on its own, the locking mechanism and how the cords are stored. | I need to be able to set up and put away my steam generator without turning every ironing session into a chore. A separate water tank can make the iron lighter, but the base remains bulkier. |
| Heat-up time and runtime | Check the exact model’s heat-up time, tank capacity and how easy it is to refill. Compare the stated runtimes with the conditions under which they were measured. | For a few shirts, I prioritise quick start-up. For a large pile, I am more interested in a tank suited to my usual ironing time and minimal refilling. |
| Descaling and limescale maintenance | Read the instructions before buying: check the collector, alerts, rinsing process and required steps. Also check the availability of parts and after-sales service for the model you choose. | I want a procedure I will genuinely follow over time. In its testing protocol, Que Choisir identifies limescale build-up as a leading cause of breakdowns. |
These figures alone do not tell you how well the appliance will perform on different fabrics or how long it will last. Que Choisir assesses steam output, crease removal on several fabrics and resistance to limescale separately.
Start by comparing tests that clearly explain their methodology, then check the specifications of the exact model rather than those of an entire product range.
The iron on a steam generator may be lighter thanks to its separate water tank, but the complete appliance needs more storage space and takes up more room on the ironing board. An appliance that is awkward to set up may be used less often.
Measure your cupboard, setup area and route to the nearest water supply before choosing. A locking mechanism for the iron and cord storage can also make it easier to move around.
According to Que Choisir, start-up times range from a few seconds to more than ten minutes, depending on the steam generator. A large tank does not necessarily make up for slow start-up during shorter sessions.
For short-term use, prioritise quick preheating and simplicity. For large piles, look for a removable tank and runtime suited to your routine.
Limescale build-up can lead to reduced performance or a breakdown. Procedures vary between models, and some systems require specific accessories or steps.
Choose a system you are prepared to maintain regularly, keep the instructions to hand and check access to parts and after-sales service for the exact model.
Calor regularly features in French comparisons, with Express and Pro Express models covering different levels of power, capacity and features.
The PerfectCare range includes compact steam generators and models with large tanks, with integrated descaling systems available on selected models.
The CareStyle range includes steam generators with different tank sizes, descaling options and, depending on the series, vertical ironing.
These Joybuy options are intended for frequent ironing of large piles of laundry on an ironing board, with particular attention to runtime, crease removal and maintenance.

For large piles of laundry, its 1.8 L removable tank is stated to provide more than 1.5 hours of continuous ironing.
The specifications state 150 g/min of continuous steam, OptimalTEMP with no temperature setting required for ironable fabrics, and Smart Calc-Clean with a collection container. Check the heat-up time if you alternate this with very short sessions.

This steam generator could suit substantial ironing sessions if you want a removable tank stated to provide more than an hour of ironing.
The specifications state a 2-minute heat-up time, 120 g/min of continuous steam, a 360 g/min boost, vertical use and Smart Calc-Clean with a container. Check the detailed descaling procedure in the instructions and compare the dimensions with your storage space.

Its 2 L tank is worth considering if you want to minimise refilling during a long ironing session.
The specifications state a Steam Boost function and vertical ironing. Before buying, check the descaling system, actual dimensions and exact heat-up time if storage space or quick availability matters to you.
No. It is mainly worthwhile for large quantities of laundry or fabrics such as linen, heavyweight cotton and some mixed fabrics. For shorter sessions, a good iron is generally more compact and quicker to start; Que Choisir points out that the difference in results is not always significant compared with a good iron.
It can be convenient for carrying out a long session with fewer interruptions, but check the capacity, whether the tank is removable and how much space the appliance requires. Operating times stated by brands depend on the steam setting, so they cannot be used to compare every model directly.
Read the instructions for the exact model before choosing: identify the system provided, any alerts, the required steps and whether it has a collector or container. Que Choisir identifies limescale build-up as a leading cause of breakdowns, and procedures vary between models.
Often yes, but always follow the instructions for the model you buy. Que Choisir states that most steam generators can operate with tap water; however, specific guidance may apply depending on the appliance or the hardness of your local water.
Do not put it in your household rubbish. ecosystem lists steam generators among the electrical and electronic equipment that must be decontaminated before recycling; find a collection point and check the take-back arrangements offered when replacing the appliance.
