Thank you for your question on the vacuum to picking up.Without the model number I can only give you so basic things to look for. The usual problem with vacuum cleaners not picking up is that the air flow is blocked by a restriction either in the hose or air path from the floor to the dust box on the vacuum.Depending on if it is a canister or an upright you can check the hose for a blockage or check the floor nozzle dirt build up that is causing a blockage.Please make sure the dirt bin is empty and that all the filters have been replaced. You may have to take the nozzle sole plate off to see if there is a blockage from Christmas trimmings in the base.Sometimes the blockage is only partial and then with time it will continue to build up until it is totally blocked. If you will give me the model number of your vacuum we can continue to troubleshoot with that information.Sam A.
