UWANT Portable Carpet & Spot Cleaner B300Pro

This is my first spot and carpet cleaner. Overall I am happy with the results it provides. It's easy to use and clean. The design is beautiful. I have used it on both carpets and upholstery with satisfactory results. I've found that the cleaning solution you use has a lot to do with the final results. If I could change anything, I would like to have the cleaning head be about 20% bigger, or a second, larger cleaning head should be either included with the machine or be at least available as an accessory.
