Why does my central vacuum has no suction?

Regarding this, why does Central Vacuum lose suction?

The hose has to be checked without it being plugged into a wall valve because the pipes may be clogged. Check the hose by inserting it directly into the main vacuum unit in the garage or basement. If there is no or low suction, then the clog is in the hose.

Why is my Dyson losing suction?

The brush bar can become blocked and cause a loss of suction. A severe blockage will trip the thermal fuse and shut down the vacuum cleaner altogether. Unplug the vacuum cleaner, carefully flip it over and examine the area of the brush bar. Clear any paper or other debris that may be caught here.
