Could it be something Im doing wrong, cause im heating the old solder joints untill its liquid, and im bringing the sucker as close as possible and relasing trigger. There is always too much solder left over that dries again and keeps the components in place.
You will need to reload and release the sucker several times while you keep the iron on the joint. Most desolder operations should only take a few seconds, so be careful not to overheat the components and PCB traces. Afterwards, you can use the wick to soak up any excess solder that may be keeping the component leads attached to the pads. The solder will cling to any metallic surfaces inside the sucker, so you'll need to clean it regulary, removing solder with a small screwdriver and rag if necessary. You should lube the inside sleeve of the sucker with a drop or two of light machine oil. This will ensure that the O ring seals nicely but still moves quickly when the trigger is released and the oil also keeps solder from sticking to the metallic parts.
edit: the nozzle tip will melt and widen with time and you will either need to replace the tip (if possible) or the sucker. I have three suckers and they have lasted two years without the tips becoming useless.
