The video shows a person using a vacuum hose to clean up wood shavings from a wooden surface. The person is holding the hose with both hands and moving it back and forth over the area where the shavings are scattered. The vacuum appears to be effectively picking up the debris, leaving the surface cleaner as the person continues the task. The setting seems to be a workshop or a similar environment where woodworking is taking place.
A person holds a black, flexible hose and positions it over a small hole in a wooden surface, which appears to be part of a workbench or similar structure. The person inserts the hose into the hole, pushing it further in with both hands. The person continues to push the hose deeper into the hole, ensuring it is securely placed. The person adjusts the hose to make sure it is properly positioned and aligned with the hole. Finally, the person gives the hose a final push to confirm it is firmly in place.
