Review on 🧹 Large Happy Tree See-Through Wand Head for Upholstery/Carpet Cleaning – Convert Wet-Dry Vac into Efficient Extractor! Perfect Detailing Hand Tool for Portable Extractor & Truck Mount by Matthew Hall

This is the only clear nozzle I have been able to find that is not specifically designed for use with a vacuum cleaner. I hooked it up to my wet and dry vacuum (I had to use one of those universal step adapters to attach it to my hose) and vacuumed the carpet after a thorough sweep. The transparent nozzle helps to see the color of the liquid being sucked up and tells you whether the carpet is clean or not. In general, the nozzle makes a solid and well-made impression. I've dropped it a few times and so far it's holding up with no issues.
