When the product arrived, assembly was a breeze. The unit is lightweight and powerful. It’s also ergonomically correct, making it very comfortable to use. The powerful brush followed the grout lines effortlessly, which made the Grout Groovy easy to control. My wife, my daughter, her boyfriend and I all tried it and were amazed (and grateful) for the ease of use and overall effectiveness of this product
The Grout Groovy did exactly what it was designed to do. We accomplished in a few hours what would have taken a few days, and the results were amazing! I highly recommend this product to anyone who has a tile floor.
