I can buy a handheld steam cleaner costing from $20 to hundreds of dollars. Why should I buy a more expensive machine?
The more expensive products generally have better safety features, the boilers are likely to be made of stainless steel, the wiring and switches may be heavier and of better quality, more and better quality attachments, for example. You can usually expect a more expensive machine to last longer and, in general though that’s not always the case, to do a better job.
