The bottom line is the finished product! Whether it's bonneting or HWE, long as the custy is happy and you let them know beforehand how the carpets are going to be cleaned then as far as I'm concerned both parties are happy.
We don't bonnet every job as we all know each job is different. If someone has a 25K truck mounted system, or someone has a 4k or even £500 machine ,down to someone bonneting, each job is different, and I will not knock anyone for what method they choose to use. It's personal choice. Some jobs we price up, we know straight away HWE job, others bonneting.
