I just bought a new vacuum cleaner a few months ago for my home. Lately it seems to have lost it's suction power and I'm not sure why. Any opinions?

Since it is a newer vacuum cleaner you should first check to see if the bag is full and also change the filters if needed. Also make sure that your vacuum bag is put in correctly and tightly sealed. If all is good there then next you should make sure the hose is not plugged or cracked. If all else fails it could very well be that there is a problem with your motor and you should then take it in to have it looked at.
