Buying guide: how to choose a steam cleaner

A steam cleaner is judged on how quickly it produces steam, how forcefully it projects it to lift dirt, and how long it can run before needing a refill. Power, steam pressure and tank capacity are the three criteria that truly set appliances apart.

What to check

Power, for a fast steam build-up Power measures the appliance’s electrical consumption, in watts. It determines how quickly water turns into steam and how well the appliance sustains its steam output during use. Market readings place the lower end around 600 W, the median close to 1,500 W, and the higher end near 1,900 W. On the product page, a longer bar signals an appliance that heats up faster and stays effective on stubborn dirt, without long waits between uses. Market median: 1,500 W

Pressure, for steam that penetrates Pressure measures the force at which steam leaves the appliance, in bar. Higher pressure lets steam penetrate more deeply into surfaces and lift dirt more easily without excessive scrubbing. Market readings range from about 3.5 bar for the weakest models to 4.5 bar at the median, up to 5 bar for the best performers. On the product page, a longer bar indicates steam that penetrates more effectively, useful on grout, greasy surfaces or stubborn fabrics. Market median: 4.5 bar

Tank capacity, for autonomy Capacity measures the volume of water the tank can hold, in litres. The larger it is, the longer a cleaning session can run without needing a refill. Readings show wide variation: around 0.3 L for the smallest tanks, 0.36 L at the median, up to 1.7 L for the largest. On the product page, a longer bar means more comfortable autonomy, particularly useful for large surfaces or extended cleaning sessions. Market median: 0.4 L

Everyday use and maintenance A steam cleaner needs regular upkeep to maintain its performance: the tank and heating circuit build up limescale over time, especially with hard water, which can slow steam build-up. Periodic descaling and using suitable water help extend the appliance’s lifespan. On the usage side, factor in the heat-up time before first use and check that the appliance suits the surfaces being treated, as some materials do not tolerate intense moist heat well.

What you get for each budget

Less than €40

At this price level, appliances generally offer more modest power and pressure, with a smaller tank, suited to occasional use on small surfaces.

€40 to €100

This tier brings more balanced appliances, with power and pressure closer to the market’s median values, for regular household use.

More than €100

Above this threshold are the most capable models, with higher pressure and larger tank capacity, built for longer or more intensive cleaning sessions.

Frequent mistakes

Choosing based on power alone without checking pressure, when pressure is what determines how well dirt gets lifted.

Underestimating tank capacity and having to stop mid-session to refill.

Overlooking maintenance of the heating circuit, which scales up over time and gradually reduces performance.

Comparing prices without considering actual specifications, since two similarly priced appliances can score very differently on power or pressure.
