Testing by experts, give us confidence of durability, elasticity and high adhesion on all surfaces (terrazzo, parquet, parquet, smooth and rough floors). Easy to assemble, please follow the instructions mentioned in the description below. We are going to specify the 4 steps to follow to disassemble the wheels of your iRobot vacuum robot. STEP 1 Disassemble the vacuum robot wheel, unscrew the bottom cover of the iRobot then the wheel, once the two wheels removed, we move on to step 2. STEP 2 Remove the old tire from the wheel module. Then with a flathead screwdriver or similar object, insert it between the rubber to be removed and the plastic, then pull the tire and the points that join it to the wheel come unhooked. OPTIONAL: With a blow dryer or stripper, apply heat to the tire area (CAUTION AT START), this will expand the rubber and make it easier to remove. STEP 3 Place the tire on the diameter of the wheel and press down to properly seat the tire in place of the removed rubber. STEP 4 Put the wheels back on the robot. Once the tires have been changed, mount them by performing the reverse procedure of the step 1 and your Roomba is ready to roll again.
