Just imagine every week full, not one space or hour left working 6 days a week with working coming in all of the time but..... you only can do so much and as it averages out you only get the same wage another cleaner would be good but his wages would buy a TM.
Also look at it another way, when it's busy it's busy you have to turn work away, well you can fit more in with a TM and when it's quieter it's cheaper than having staff sat around, at Xmas it would pay itself with the extra work, and the average custy is so impressed without mentioning 'Marketing', it is done for you!
I had a Bane clene before my petrol, but with the pipes coming out of the van and the noise outside it created loads of 'street enquiries' that is when I really found out about referals, I was offering what was percieved to be different and also a better clean, so I got even more busy and it goes on and on.
