Tired of your Roomba getting stuck under furniture? These bumper extensions are the solution. By raising the front bumper height, your Roomba can navigate around your home smoothly without getting trapped under low-clearance furniture. The set includes two pieces, one for each side of the vacuum, ensuring a balanced elevation. They're easy to attach with glue or the included 3M stripe, and won't interfere with your Roomba's normal operation. We can customize the model according to what you're looking for. Want it in another size? A different color? No problem! Just send us a message! 3D printed objects aren't always perfect. Because they are made layer by layer, there might be visible lines and defects, but we'll try to make it as smooth as possible. Most of our products are made from high-quality recycled PLA, a material that is not only durable but also environmentally friendly. It's important to note that they are not dishwasher safe. The best way to clean them is to wipe them with a damp cloth. IMPORTANT: Please make sure your shipping address is accurate and track your package using the provided number.
