Replacing vacuum wheels becomes necessary when they are worn or damaged, affecting the vacuum’s mobility. Signs that it’s time for a replacement include poor movement, unusual noises, visible wear and tear, or wheels that get stuck despite cleaning. Vacuum wheels come in various types, such as standard plastic, rubber-coated, or swivel wheels, with some being brand-specific and others universal. To replace them, first unplug the vacuum, access the wheels, and remove the old ones using the appropriate tools. After installing the new wheels, ensure they move smoothly before use. Regular cleaning and avoiding rough surfaces can help extend their lifespan, ensuring your vacuum continues to glide efficiently across different floors.
