I'm not getting involved in pricing arguments, as it's very difficult to determine what an individuals bottom line actually is.
What I will comment on, is three hours to clean a suite and your thought that it can't be done in less. When I started I took even longer than three hours on some suites, but would take half as long today, through using better equipment, better products and effective use of these.
For instance, there's no point in beating yourself up with thoughts that " you must thoroughly vacuum every corner of every suite, every time, when in many cases they don't need vacuumed at all, need only vacced in certain areas, only need a quick brush.
Also, it's not CHEATING or FRAUDULENT or WORKING TO A LOW STANDARD to only lightly clean backs and sides of suites ( unless of course they are heavily soiled )
Effective use of good presprays, proper aggitation and rinse / extracting with the most appropriate tools will also speed up the process and avoid overwetting.
The price you charge and the standard you work to, should be weighed up against your clients' expectation which will vary from client to client, but your average job ticket will increase by at least 50%.
There were four posts added while I was typing which were interesting to read, but I will refrain from getting involved in the pricing comments, this time.
