Shark Infinity NV31 Upright vacuum cleaner
Sunday, October 26th, 2008
Other vacuums use filters or bags that clog and lose suction. Infinity uses 24 cyclones that never clog and never lose suction.
The problem is that after minimal usage, other vacuum cleaners can lose up to 50% of their suction power. Instead of a cyclonic dirt separation chamber, those vacuums use filter media that can become clogged over time and still need to be replaced. Consumers who have these vacuums eventually experience loss of suction over time. There has been no way to avoid this until now.
