First, check the hose, wands, and power nozzle. You can check the hose by dropping a coin in one end, then lifting the length of the hose until the coin drops at. If it doesn't, then there's an obstruction in the hose that needs cleared. Depending on where th blockage is, it can be difficult to remove. The best way is to connect the wrong end of the hose directly to the in port of the vacuum and turn on. This presents an opposing suction to the clog and should clear it. To check the powerhead, drop a coin in the wand end and allow it to drop through. If it gets stuck, there's a clog, probably in or near the elbow. Use a blunt object to gently push it through. You can visually check the wands. If the filter is dirty, it presents an obstruction to the airflow, and will result in a loss of suction. Rinse and dry thoroughly. I recommend keeping an extra filter on hand and alternate use. Check all outlets by plugging hose into them and turning machine on. Check for differences in airflow. If there's less suction in one than the other/s, then there's a blockage in that section of pipe, probably at one of the elbow. The obvious place would be the elbow at the outlet. Visually check for clogs. If all the outlets have a low airflow, my first guess would be the filter in the vacuum, but there could be a clog in the main piping. Another cause could be leaks in the hose, most likely at the ends where the hose connects to the connector or handle. The hose generally needs replaced if this is the case. The fan system may be bad, resulting in reduced suction. It will need to be replaced if this is the case. Depending on the age of the vacuum, the motor could simply be wearing out. The best diagnosis can be provided by a reputable vacuum repair shop. Take the entire vacuum in for trouble-shooting if none of the above helped.
