I'm sorry to hear that you had a problem. The Monarch bonnets are a combination of Microfiber and polyester. The blend gives it a nice combination of effective agitation and the benefits of Microfiber. It strikes a nice balance of cleaning efficiency and absorption.
Microfiber bonnets are going to be less aggressive to the fiber than other typical bonnet materials, such as cotton or synthetic fiber. So they are a good choice for more delicate carpets. However, you ALWAYS need to exercise caution using any bonnet, especially on a residential carpet with twisted yarn.
And although Microfiber is less stressful to the carpet than other bonnet materials; ALL bonnet or pad cleaning should be performed with the same degree of caution:
1) Spray the carpet with the detergent. You will need plenty of lubrication. The sprayed detergent provides the cleaning power. It also LUBRICATES the yarn. So don't skimp on the application of your detergent.
2) Wet the pad or bonnet before using it. Dunk it into a bucket of water. Pull it up. Wring it lightly. You want the pad or bonnet to be slightly wetter than "damp". Now that you have a wet bonnet, plop it onto the carpet.
3) If you are cleaning a cut pile carpet, always use a glider. Place a glider onto the carpet (velcro side up). Place your wet bonnet on top of the glider. Then place your machine over the top of the bonnet.
4) Always keep the machine moving. Avoid any tendency to stand in one one spot for more than a second or two. If it is a cut pile carpet, there is a tremendous potential for tip blooming, regardless of what kind of bonnet you are using. So exercise good judgment and be very careful running the machine!
5) Don't let things dry up. If your detergent is drying up before you clean a section, re-spray the carpet. If the bonnet is beginning to get dry, it's time for a fresh bonnet - or else dunk the used one back into your dunk bucket again. The bonnet has to be wet. You need good lubrication.
These guidelines must be followed very carefully, or you may experience problems, especially on cut pile carpet (critical on residential cut pile carpet). A lot of residential cut pile carpet is not built very well. A lot of it is cheaply manufactured with a light twist to the fiber. So extreme caution should always be maintained. Assume the worst. It's always better to err on the side of caution.
If you'll exercise due care whenever you're cleaning any cut pile carpet with a bonnet or pad, you will minimize the risk of tip blooming. Notice I used the word "minimize". That's because nothing can eliminate the risk of tip blooming entirely - there are too many variables. However applying the guidelines above will overcome most of the problems you may encounter with tip blooming.
