Why is the suction decreasing on my Sovereign MWW806-20L-1400WA?

Several factors can cause decreased suction in your Sovereign Vacuum Cleaner. The flexible hose or extension tube might be blocked; gently remove any obstructions using a long stick. Also, the tank may be too full—empty it completely. The cloth or foam filter could be dirty or clogged. Clean the cloth filter by patting it carefully and cleaning it with a fine brush. Clean the foam filter with a little detergent under running water. If the suction continues to decrease after cleaning, replace the filter.
