Cordless or Corded Steam Mops

best steam mop 1Steam mops use mains power for operation since water heaters require plenty of power. When turned on, the water heater requires 20-30 seconds to heat up the water and to start to produce the steam. Most steam mops have heaters in the 1500 – 1600 W range.

The length of the power cord determines the area that can be covered using a single power outlet and if one must change the power outlet, the water heater requires additional 20-30 seconds to heat up the steam again.

The common length of the steam mop’s power cords is around 25 feet (~7.6 m).

Cordless steam mops use both mains power and onboard batteries. When plugged in, their water heaters are operational, but when working in cordless mode, they are not producing steam. Instead, batteries are used to power water pumps to spray water and perhaps the cleaning agent on the cleaned area, to power the scrubbing system (if one is present), and to power electronics required for normal operation.

Using a battery for powering a water heater would significantly reduce operating time, or it would require a large, bulky, and very expensive lithium battery.

How Steam Mops Clean

There are several mechanisms used by steam mops to clean the floors, but the most important ones are hot steam and cleaning pads.

One of the benefits of using steam mops is the fact that hot steam kills at least 99.9% of bacteria and germs on the floors, at least in lab conditions. In real life, this percentage can be even greater, if the steaming time is prolonged. This is very important for people with pets and kids.

Cleaning pads come in different versions, optimized for different floors and amounts of dirt. When they get dirty, they are easily replaced with a clean one and after cleaning the floors, they are washed and reused.

One must be very careful when replacing a dirty pad with a clean one since the dirty one is probably very hot due to the use of steam for cleaning.

best steam mop 2Some steam mops have edge bristles to help remove the dirt from the edges and corners, while others can have triangular cleaning heads to ease access to hard-to-reach surfaces.

To improve cleaning even further, some steam mops feature scrubbing systems that scrub the floor with cleaning pads up to 800-1000 times per minute, greatly enhancing the cleaning effect.

Note that scrubbing system and hot steam should be used only on surfaces that tolerate such cleaning like tiles, marble, stone and other, very resistant surfaces. The use of hot steam with a scrubbing pad system can damage surfaces like a hardwood floor, laminate, or even carpets. If there is a crack in the wood finish, steam can penetrate the wood and make it change shape and start to rot.

Rough cleaning pads can make scratches on sensitive surfaces of wooden floors and laminate, too. Also, if the cleaning pad picks a small stone or pebble or even sand, such dirt can cause scratches on sensitive surfaces. In order to prevent such damage and to speed up the cleaning, vacuuming before cleaning with a steam mop is recommended.

Before using steam mops on wooden floors, check if your flooring is certified for such cleaning and even if it is, test on a small area first. Better safe than sorry.

Most steam mops are not suitable for cleaning carpets – cleaning pads don’t glide over carpets easily. For such floors, many steam mops come with ‘carpet glider’, which enables the steam mops to be used for ‘refreshing’ the carpets - they clean and refresh the surface of the carpets, but most of the dirt embedded among the carpet fibers stays there.

Note: sensitive carpets should not be cleaned using steam mops - hot steam can damage the fibers and even cause discoloration of the cleaned surface.

Cleaning head width determines the area that a device can cover in a single pass. The wider the cleaning head, the larger the area cleaned in a single pass. However, a wider cleaning head requires more steam and hence a stronger water heater and thicker power cord. Also, the wider cleaning head has issues when cleaning around the edges and corners, around the furniture, stairs, and similar surfaces.

Tap Water or Distilled Water

The onboard tank capacity of most common steam mops is usually around 400 – 500 ml. Tank is filled with distilled, demineralized, or tap water or with a special cleaning solution based on distilled/demineralized water, with cleaning agents and fragrance for an increased feeling of freshness.

Tap water is much cheaper than distilled or demineralized water, but the use of tap water can lead to limescale buildup inside the cleaner. Also, tap water can leave marks on the floor. To increase the useful operating life of a steam mop, the use of distilled and/or demineralized water is highly recommended, and if one likes additional fragrances, they are available in the form of fragrance disks and liquids.

Special cleaning solutions are commonly used diluted with distilled water. They enhance the effect of cleaning and leave a pleasant scent that gives an additional feeling of cleanness and freshness. However, note that some steam mops prohibit the use of cleaning agents added to the water – for such units, the use of scent discs is recommended practice.

Steam Mop and Vacuum Combos

A special type of steam mop is a steam mop and vacuum combination. Such devices operate like small steam vacuums – they vacuum the area first and then clean and sanitize it using hot steam in a single pass. This way, cleaning is much faster, since the device is doing two jobs at the same time and the cleaning pad can cover a larger area before it must be replaced with a clean one.

Also, as said before, any large dirt like stone or pebble that gets picked by a cleaning pad can cause scratches on sensitive floors and if the steam mop has a scrubbing system, it can almost act as a sander and really damage the hardwood floor finish.

On the other hand, steam mops/vacuums combos cost slightly more than regular steam mops, but have in mind that a very dirty area should be vacuumed first, and only then cleaned with a steam mop. Otherwise, cleaning pads should be changed very often.

Steam Mops Recommendations

Thus, here is the list of 5 very popular and IMHO the best steam mops currently on the market, which are an excellent choice for most of the people.
