Canister steam cleaners typically have a water reservoir and an attached hose and nozzle that dispense the steam. Many of these types of steam cleaners come with an array of attachments, like brushes and scrubbers, to make cleaning more effective. However, if the unit's water pressure is not strong enough, attachments may wear out quickly from the excessive scrubbing required to compensate for the weak flow. Since canister steam cleaners are bulkier than smaller handheld models, they are best suited to large jobs or outdoor projects.
Upright steam cleaners resemble a mop, with a long handle attached to the steamer. These types of steam cleaners have cleaning pads that attach to the bottom of the steamer. Since many upright steam cleaners are equipped with a telescoping handle, they are useful for cleaning floors as well as upholstery and mattresses. They are also easy to store along with other brooms and mops because of their compact shape. Depending on the size of an upright steam cleaner's water reservoir, it may need to be refilled several times during larger cleaning tasks.
Handheld steam cleaners feature a water reservoir and nozzle all in one. Some come with attachments for cleaning grout, blinds, windows and fragile items. Some also feature highly concentrated pressure to attack caked-on grime in hard-to-reach places. These types of steam cleaners are ideal for cleaning small spaces or for detail work. They will not be able to clean large surfaces like a kitchen floor.
Anyone can forgo a high-tech appliance and make her own steam to use for cleaning. Fill a tea kettle with water, and heat it on the stove until it whistles. Wear thick rubber gloves for hand protection, and pour the hot water onto a clean rag or a micofiber mophead. Wring out the excess water, and begin cleaning. This method requires a bit more effort and imagination, but it is very cost efficient and can be tailored to any cleaning job.
