"Cleaner effect" is the technical effect achieved by your invention. How on earth did you achieve this technical effect? Is it through structural improvement (such as changing bristles or something) or improvement in usage (not involving structural changes of objects)?

Patents are divided into three categories: invention, utility model and appearance.
If you want to improve the structure, it is recommended to apply for a utility model patent (or invention patent). If the method is improved, you can only apply for an invention patent. You can ignore appearance. Appearance is only the improvement of color and appearance, and it does not protect any function of the product, just the appearance.

In addition, utility model patents and invention patents are more expensive. If you apply in your own name, you can apply for fee reduction (that is, the fee you gave to China National Intellectual Property Administration can be reduced. You can go to the bookstore to look it up.

You can understand all this yourself. You don't have to go to the intermediary to ask in the first place. When it comes to the steps of writing application documents, you can see whether you write them yourself or find an agent. Theoretically, the agent is professional, but if you are looking for that kind of scum agent, hehe, I can only say that you might as well write it yourself. There are many online tutorials in bookstores (well, your improvement is the kind of life, not a particularly difficult classification, so why not? If it is that kind of circuit, process or even more complicated classification, it is still recommended to find an agent. )

Finally, if you apply for a patent number, not for protection, you can apply for a utility model, which will save money, get a certificate quickly, and most importantly, it is easy to authorize.
