Just had a look at the reviews from No1 carpet cleaning , its just a laughing matter regarding how bad customers service were and looks like half of the technicians were blind folded while on the job.
Its a total con, £19 + vat for a room, its basically a go over the carpet with a wet wand.
They even had their own so called self employed technicians complaining and not recommending anyone to join.
Kenver_Clean is right, you're not your own boss when working with them
It also gives the Airflex Storm a bad name !
