The other day a couple brought in their Miele vacuum cleaner for repair. They stated that their Miele has no power. When we performed our estimate we confirmed that the Miele vacuum cleaner has low suction. We determined that this is caused by the Miele vacuum cleaners filter being clogged. We replaced the Miele vacuum cleaners HEPA filter and this resolved the problwem. Now their Miele vacuum is back in action.
