To empty your Dyson, you should remove the canister from the vacuum. For that, press the ‘Bin Release’ button/lever or the catch on top of the carry handle. Depending on the type and model of vacuum cleaner you have, the lever/button may be in slightly different places. Some models will have it labeled, while others will have it in a distinctive color (typically red). After that, hold the canister over the bin and press the button/lever to open the base and dispose of the dirt – do this carefully over the bin or straight into a bag.
