Janiking is a great Franchise, many of the janikings here in Phx have pressure washing vans.
They actually pressure wash a very large account I wanted in Scottsdale. They got it because they needed janitor service and wanted to write one check. They have actually been doing a decent job.
I would personally by hydrotec or alladin if you cannot afford Landa. I would stay away from lower end manufactures do to down time experience with other machines.
Shop around your market, cheaper is not always better. You will however find machines costing 8,000 and some 4,000 having the specs. All machines look the same but actually are built very different. Often the cheaper ones fall apart after heavy use. Litterally fall apart, if your using them for residential they work fine. If you need idustrial stuff Mighty M is the way to go. Hydrotec builds great intermediate machines. There industrial lines are great also, I would say over all service and sales they are great.
I wont mention who to buy from or not to buy from. all the distributors online are good folks and take care of there customers.
If you have questions about real training and Issues theres guys here that are willing to help you. Good luck and maybe you should attend a Networking meeting look at actual contractors that are set up running successful business in the mobile cleaing industry.
