Why does my vacuum cleaner keep falling over when I stand it upright?

If an upright or stick vacuum will not stay steady, it may not be assembled correctly, may be resting on an uneven surface or may have a loose connection between parts. Switch it off and unplug it before you check the fit. Do not continue using it if any section is cracked, bent or unstable enough to fall and cause injury.

1. Check that the tube, handle and floor head are fitted together fully. Expected result: the unit should sit more securely when the joints are pushed home.
2. Inspect the stand, wall point or storage position you are using. A soft or sloping surface can make the cleaner topple. Expected result: a flatter location should hold it better.
3. Look for trapped debris or hair around the base that may stop it standing properly. Clear anything that affects balance. Expected result: the cleaner should rest more evenly.
4. Make sure the dust container is closed and latched, because a loose container can alter the balance. Expected result: the unit should feel more stable.
5. If it still falls over easily, or if any joint seems loose or damaged, stop using the product and contact the retailer or store where it was purchased.

Good storage helps protect both the cleaner and the user. If the machine cannot stand safely, treat that as a sign something is not fitted or balanced correctly. Generic troubleshooting.
