Based on my experience using these cross bars, they are a must-have for anyone with hard floors in their home and kitchen. They make vacuuming so much easier and more efficient, and they prevent the vacuum from scratching or damaging the floors. The only downside is that they can be a bit tricky to install, but once they're on, they're fantastic. Overall, I highly recommend these cross bars for anyone looking to enhance their vacuuming experience.
