I live in a large country house I have a large yard where I can clean my own carpets and not only. I recently picked up a high pressure washer for myself https://cleanup.expert/best-pressure-washers/ it is too powerful for carpets, but you can regurilovat power. This way I save money and time.
I started cleaning carpets at age 21 while I was finishing my degree and after 7 months I said, why not start my own business. So I bought a small $25,000 a year carpet cleaning franchise. That was 18 years ago and I have been self employed ever since.
