Portable steam cleaners, also referred to hand held steam cleaners come in many different types and are designed for a large range of cleaning applications. Many of these cleaners are much smaller than the commercial steam cleaners and are marketed as house hold or domestic use in areas of cleaning such as in the kitchen, bathroom and outside for use in the garage, car or boat. There are several different types and brands of portable cleaners available each with their own features, advantages and disadvantages.
One of the most popular types of portable steam cleaner is the jug type cleaner as they are a comparatively small unit which has multiple attachments and can access small places that need to be cleaned. These cleaners are an all in one unit where the user holds the whole cleaner in their hand as they would a jug of water. The main advantages of these jug shaped portable cleaners is they are the cheapest on the market costing between $40 to $70 an the unit is small, light weight and easy to use. These steam cleaners also feature attachments such as different cleaning heads and extension hoses to increase the versatility of the steam cleaner. The jug type steam cleaners do however have some disadvantages such as low steam pressure and a small reservoir for the water. The low steam pressure means that the cleaning effectiveness is not as good as other household and commercial steam cleaners so tougher grit and dirt may not be moved very easily. The other disadvantage of the jug portable steam cleaners is that the reservoir that contains the water is quite small and only provides 5 to 10 minutes of steam before it needs to be filled up with more water.
Another model of steam cleaner that is also portable is the canister style steam cleaner which is similar in appearance to a vacuum cleaner. These portable steam cleaners are larger than the jug shaped cleaners but have attachments to allow them to clean in tight spaces. These cleaners also have advantages and disadvantages. They usually have a higher steam pressure and larger reservoir for the water which means that the steam can give a much better clean and the unit can keep producing steam for longer cleaning times of between 40 and 60 minutes. These styles of steam cleaners are also very versatile as they include attachments for the cleaning of things such as BBQs, cars, boats and hard to reach spaces of the kitchen and bathroom. Some of the disadvantages of the canister portable steam cleaner is the initial cost of the unit which can be up to $400 and these units can be a hassle to use with the main part of the steam cleaner needing to be pulled around like a canister vacuum cleaner.

Commercial steam cleaners have been used for around 150 years for cleaning machinery especially around the railways and power stations where keeping machinery clean is important for efficiency and safety. The commercial application of steam for cleaning involves much higher temperatures than domestic steam cleaners can produce. These cleaners are used for various applications such dissolving fats, oils and grease and for sanitising or killing bacteria.
