Vacuuming up Lego pieces with a home vacuum cleaner can potentially be safe for the vacuum and the Lego pieces, but there are some precautions you should take to avoid any issues:
Size of Lego pieces: Most standard home vacuum cleaners are designed to handle small debris like dust, hair, and crumbs. If the Lego pieces are relatively small and won't cause clogging or blockage in the vacuum's hose or filter, then it should be fine.
Check the vacuum's power: High-powered vacuums, such as industrial or shop vacuums, may have strong suction that could damage or break the Lego pieces. Using a regular home vacuum with a lower suction power is safer.
Nozzle or attachment: If possible, use a nozzle or attachment with a wider opening to vacuum up the Lego pieces. This can reduce the risk of small pieces getting stuck in the vacuum's hose or filter.
Inspect the Lego pieces: Before vacuuming, inspect the Lego pieces for any sharp edges or points that could potentially damage the vacuum's components or cause the vacuum bag or canister to tear.
Empty the vacuum afterwards: Once you've finished vacuuming the Lego pieces, make sure to check and empty the vacuum cleaner's bag or canister. This will prevent any potential damage to the vacuum from the weight of the Lego pieces or from debris getting stuck inside.
Alternative method: An alternative method for cleaning up Lego pieces is to use a handheld dustpan and brush. This allows you to manually pick up the Lego pieces without any risk to the vacuum.
If you are uncertain about the suitability of vacuuming Lego pieces with your specific vacuum cleaner, it's best to refer to the manufacturer's guidelines and recommendations. Additionally, if you have valuable or rare Lego pieces, you may want to consider other cleaning methods to avoid any accidental damage.
