With a high/low power switch, the new GoFree Flex Pro II brings greater versatility and options to professional cleaners. By cleaning at a rate 30% faster than a corded backpack and 5x faster than an upright vacuum the GoFree Flex Pro II will save time and money. High/low power settings conserve runtime by tackling routine cleaning on low then switch to high for deeper cleaning. Working without restrictions means going wherever you need to go to get the job done.
