The machine you choose for your home should work for its size and the tasks you want to do. Remember that the smaller the steam cleaner, the more often you will have to refill its reservoir.
Other features that can be important are ease of use, noise levels, and warranties. Larger machines, especially those powered by diesel, can be noisier. Check the warranty period and what it covers. Most well-known brands will cover the boiler, while some also provide coverage for the entire unit. Handle controls are also a nice touch as you don't have to bend down to adjust the steam flow. Finally, because steam vacuum cleaners use boiling water, check for safety features like child locks and safety valves to minimize the chance of injury.
