13 Best Cordless Steam Cleaners in 2025 – Reviewed & Rated

Before explaining how to choose an excellent cordless steam cleaner, we prefer to clear the field of two common misconceptions. By analyzing the requests for clarification that come to our editorial staff and the questions published by potential buyers on the various e-commerce sites.

It is possible to understand how there are two false beliefs. The first is that the steam cleaners suck the dust before or simultaneously with the steam supply; the second is that they also run on battery power.

Both, unless you consider more expensive models and for professional use, are wrong. Strictly speaking, steam cleaners, whether they are steam guns, electric steam brooms, or steam generators, do not integrate a suction motor and need electricity, therefore an outlet to connect the plug to in order to work.

Here we had listed out some of the best cordless steam cleaners that are present below.

Things to Consider Before Buying Cordless Steam Cleaners

Maximum Hygiene without Detergents or Chemical Solutions

The title of this paragraph summarizes the success of this particular type of household appliance. Steam cleaners use the high temperature of the water vapor (always above 100 ° C) to thoroughly clean and sanitize objects and surfaces, removing more than 99.9% of the bacteria that accumulate on them.

What pleases consumers of steam cleaners is, therefore, the possibility of cleaning without using powder or spray detergents, chemicals, or anything else that may be harmful to the health of adults and children.

All tests conducted in the laboratory show that the cleaning power of water vapor exceeds that of regular supermarket detergents. So if you had doubts about the ability of steam to remove dirt and bacteria, you can easily dispel them and decide on the purchase.

For many, relying on steam has become not a convenient solution, but a way of life. A bit like choosing to eat organic. The offers that flock online have also contributed to the spread of steam cleaners by definitively solving the dilemma of where to buy at the lowest price.

You can buy the best brand cleaner online without investing large amounts. Let’s see now how many types of steam cleaners exist.

Steam Gun, 2-In-1 Electric Broom, or Towed Steam Generators?

When talking about steam cleaners, it is good practice to specify their type. In fact, there are steam guns, two-in-one devices, and towed steam generators on the market.

In this service – you have already guessed it – we will not deal with electric steam brooms with an integrated vacuum cleaner, with the aim of offering you an overview of products at an affordable price and easy to use.

Steam guns are practical, light, handy, and comfortable to store almost anywhere thanks to their petite size. In addition, they are often offered at low prices.

According to reviews published online, steam guns are unsurpassed when it comes to quickly clean hobs, sinks, washbasins, sanitary ware, sofas, mattresses, curtains, and any other object that is at least half a meter high from the floor.

With a good steam gun, you can sanitize the whole house, including windows, and even, if equipped with the appropriate accessory, iron and refresh clothes vertically by exploiting the ability of water vapor to eliminate creases from fabrics without damaging them.

The only use for which steam guns are not indicated at all – and this is the main disadvantage of this category of product – is washing the floor. In this case, you may be interested in a good mop.

Tank Capacity and Heating Time

Who among you would like to interrupt cleaning continuously to top up the tank and have new steam available? The question arises when steam cleaners consider the capacity of the tank to be filled with water and the guaranteed average autonomy (not to be confused, as already mentioned in the introduction, with the energy autonomy of battery devices).

Fortunately, the models that this buying guide takes into consideration have enough autonomy to perform most of the ordinary cleaning operations. The fact that the steam is delivered only if the button that allows it to come out is pressed guarantees the total absence of waste.

This particularity, which distinguishes almost all steam cleaners, is in honor of their true cross and delight. If, on the one hand, as just pointed out, it prevents steam from being unnecessarily dispersed in the air, on the other hand, it forces you to keep your finger always under tension.

For some users, especially women, this is a bit tiring (from this point of view, online opinions are clear).

As for the heating time, i.e., the time it takes for the steam cleaner for the water contained in the tank to heat up to the point of being emitted in the form of steam, not all cleaners are the same. Some take longer than others.

Steam Pressure and Accessories

The technical data sheet of most steam cleaners includes the item “steam pressure.” This is the pressure exerted by the steam at the exact exit point and is measured in the bar ( CGS System unit of measurement – centimeter-gram-second system).

A bar is roughly equal to the pressure that the Earth’s atmosphere exerts on every square centimeter of our body, at sea level, at a latitude of 45 ° and at a temperature of 0 ° C.

The higher the outlet steam pressure, the greater the cleaning capacity of our new appliance. However, consider that it is sufficient to connect a rigid or flexible extension tube to the vaporizer, if provided by the accessory fleet, to obtain a lower pressure steam jet.

Also, do not confuse pressure with steam temperature, clearly distinct physical characteristics. To better understand the effectiveness of higher pressure, think of the water that comes out of a standard irrigation hose and that emitted by an ordinary high-pressure gun designed for washing cars.

The high-pressure steam cleans better, especially in hard-to-reach places, in confined spaces and along the joints of the tiles. In some cases, it also saves you the trouble of wiping the rag, after dissolving the dirt, to remove all its traces.

The pressure of the steam emitted by the cleaners on the market is, on average, between 3 and 5 bar. To make it easier to search for the best steam cleaners of 2020 and read their technical datasheets, we explain how to obtain the pressure value in the bar if this is reported in another of the most common units of measurement, namely Pascal ( Pa).

Equally crucial in giving the steam cleaner, greater efficiency is the accessories. Whether it’s a “two-in-one,” a “pistol” or “tow” cleaner, accessories can make the difference, up to compensating for a record pressure of steam delivery.

Extensions, flat nozzles, nozzles equipped with bristles and washable microfibre heads can transform our new steam cleaner into an all-round household appliance that you can no longer do without.

The cleaning heads to which the microfibre cloths are applied are, for example, comfortable for the sanitation of sofas, cushions, mattresses, and upholstery in general.

Range and Weight

There are two other aspects to consider before comparing the prices of the various models or buying the cheapest steam cleaner. The radius of action is closely related to the length of the electric cable.

It may seem strange to you, yet companies try to reduce production costs in every way, also saving on electrical cables. A short thread forces a continuous change of grip, a longer one, on the contrary, allows you to wash different surfaces without having to interrupt the work.

The length of the electric cable, therefore, the range of action takes on particular importance, especially with the steam cleaners of the “two-in-one” type and with the towing ones.

No less important is the weight, especially if the choice of your new steam cleaner falls into the category of laptops. With these, in fact, the weight of the appliance will be entirely borne by the arm.

Consider well because over two kilograms, the arms of thin-bodied subjects or elderly women may be affected already after a few minutes of work.

Weight is less important if you are interested in a 2-in-1 electric steam mop or a tow model. In both cases, the floor will absorb too many grams even if you will give it the movement in various directions.

Do Steam Cleaners Heat the Room?

The answer is yes. By dispensing steam at a temperature of over 100 ° C, which, due to the difference in density compared to the surrounding air, rises upwards, the steam cleaners tend to heat and make the environment in which you are operating more humid.

And this side effect, if it goes completely unnoticed in winter, autumn and spring, can instead be felt during the summer.

From this point of view, steam guns, in particular, emitting relatively thin jets of steam, are more “painless.” You may instead experience some effects of heating if you pass the electric steam mop or if you use the towed one.

Nothing unbearable or harmful, it is clear, but it is good also to describe this aspect in a market guide that claims to offer you complete and exhaustive information.
