How do steam mops work?

Steam mops have an internal mechanism that creates steam, which is pumped out of a cleaning head. In theory, this steam loosens grime, and the cloth cleaning head wipes it away. Steam mops claim to make it easy to clean grimy floors without the use of chemicals; some manufacturers even claim that the hot steam helps kill bacteria and mites.

Can steam mops clean up spills and stains?

We think steam mops are far more convenient than a mop and bucket but will only work well in certain circumstances. 


Like vacuum cleaners, steam mops come in stick and canister forms, but they don't have suction power. If you need to clean up large amounts of spilled liquids, you'll need a conventional mop or a wet and dry vacuum cleaner instead. We also recommend sweeping up or wiping excess dirt or stains from the floor before using a steam mop because you'll probably still be spreading the muck around.

Stain removal

Steam mops aren't great at stain removal but keep in mind that this is dependent on the flooring you have, as some stains soak more easily into certain types of floors over others. While not perfect, they probably do remove stains better than a mop and bucket. And while they can be good at removing new stains, don't expect them to instantly lift years of longstanding dirt.


If you clean infrequently or have in-ground stains, particularly in the grout, then a steam mop may not be the best choice. We tested how well steam mops cleaned cola and tea stains from grout, and they all did a poor job. Steam mop pads aren't designed to get into recessed grout, and steam is, well, just hot water, and that's often not enough to remove in-ground dirt. For these jobs a steam cleaner with jet nozzle tools and a brush may help, but they're only useful on small areas.

Carpet and upholstery

Most models claim to rejuvenate carpet and upholstery, and while we've found they do refresh the carpet's appearance, they don't actually clean it.

Can I use a steam mop on floorboards?

Steam mops can damage the surfaces of cork tiles and unsealed or waxed timber. However, they should be suitable for most hard floors, including vinyl, ceramic tiles, linoleum, marble, stone and sealed timber – with some caveats.

Some manufacturers of timber flooring express concerns that the steam is forced between the boards and cracks in the surface, causing them to expand. Over time this could cause problems such as delamination, buckling and cupping (raised board edges), or it may shorten the life of some coatings. Read your flooring manufacturer's warranty to see if it specifically states that steam mops are not to be used.

Similarly, steam could seep into the joins of vinyl tiles and weaken the adhesive. Sealed ceramic or stone tiles are fine with steam, but it still pays to check if your particular tile is suitable.

Does a steam mop get rid of bacteria and viruses?

Most of the tested steam mops have claims of some description around killing or eliminating bacteria, but of course these come with caveats. 

Some even mention coronavirus in their marketing, with the inevitable footnote claiming that spot cleaning for 30 seconds at maximum steam level would remove a majority of enveloped viruses such as coronavirus or influenza when removing from common smooth household hard surfaces, however most people are unlikely to spot clean their entire bathroom, or even the heavily trafficked areas with 30 second bursts.

Killing bacteria or viruses relies on a high temperature. All steam mops have a 'mop' part, which is a pad that attaches to the steam generator – when the steam exits the device, this pad will absorb a lot of that heat and it'll end up exiting onto the surface you are cleaning at a lower temperature than straight steam onto a surface (such as with a steam cleaner).

Of course, most steam mops will remove bacteria and viruses from hard smooth surfaces, just as a normal mop with soap and warm water would and a sponge with the same. However, that means you put the bacteria or virus onto the steam pads attached to the steam mop. The steam generated by the machinery of the steam mop might be enough to destroy the bacteria or virus collected on the pad, but the steam generator and pads will differ in effectiveness, so it's important to throw the pads in the washing machine afterwards with laundry detergent.

Laundry detergents will be the ingredient that breaks down the virus as it disrupts the fatty envelope of its cell walls and the friction of the washing machine will tear the weakened walls of the virus apart.

Best steam mops? We review the pros and cons

Our quick guide to steam mops - as seen on TV!

Key features to look for

Water tank

Look for a water tank that can be refilled while cleaning without having to first turn off the mop and let it cool down.

Cleaning pads

These are usually microfibre to trap and carry away the shifted dirt. Some come with more than one pad, sometimes of different types, which is handy for swapping over during a long cleaning job, or if one is in the wash when you want to do some steam cleaning.

Carpet glider

An attachment for using the mop on carpet. This is handy for refreshing carpet and removing light soiling, but for heavy soiling or stains you'll probably need a heavy-duty steam cleaner (and/or carpet shampoo).

Pad rest

You might want one of these for sitting the mop on during a cleaning job (if you take a quick break to answer the phone, for example), so it can sit in one place for a while without damaging the floor.

A telescopic wand

When you can adjust the wand to suit your height, you don't have to bend your back too much.

Power cord

This should be long enough that you have good reach from the power point. Know where your power points are before you shop for a steam mop.

Accessory tools

Tools such as a jet nozzle or brush can be useful for cleaning grout, shower cubicles and other areas.

Window cleaning attachment

Some models also comes with a handy window cleaning attachment. 

Steam-ready indicator

It's handy to have a feature that tells you when the steam generator has heated up and is ready to run.

Steam-on lock switch

An on-lock activates continuous steam flow, so you don't have to hold down a trigger or button to keep the steam coming.

Steam-off lock switch

An off-lock is a safety feature – like a safety catch – to help prevent accidentally turning on the steam flow.

Heat-up time

If you want to quickly get your steam mop out, you'll want it to heat up quickly! Heat-up times can range from 20 seconds to several minutes.

Time in use

Ideally, you shouldn't need to keep refilling the water tank in the middle of your cleaning – particularly if refilling is tricky or can't be done on the go.

How much does a steam mop cost?

Steam mops range in costs from $49 up to $599.
