Dyson Vacuums: What Makes It So Practical?
Before Dyson came along, all vacuum cleaners used purses, but as the bag loaded up the vacuum cleaner lost suction power. Dyson vacuum cleaners don't have a bag and they don't lose suction energy. Instead use centrifugal power to generate suction energy. The trademarked patented Root Cyclone technology rotates the air at very high-speed, which generates powerful suction energy. The dust is gathered in the vacuum's clear nasty bin drum - no suction power is lost, even when the bin is almost full.
