Details: and high quality. Made of high quality material, durable and practical to use. The wheels are severely worn, unable to connect to the rough ground, and the pushing resistance is increased. The wheels cannot touch the ground, causing the shell to scratch the floor for a long time. Long-term friction of the shell will bring about a series of chain reactions such as burrs, abrasion of the bottom cover, and drop of the brush bar. It is recommended that the wheels be replaced every 6-12 months Replace part number: 967435-01 For DC35 / DC44 / DC45 / DC59 / DC62 All V6 SV03, SV05, SV06, SV07, SV09 Absolute, SV09 and more Material: Plastic colour: Black+Silver Package Contents: 10 x Axles 10 x Rollers Only the above package content, other products are not included.
