don't come cheap, and the ones that do tend to be terrible. Enter the $299 Trifo Ironpie. Despite its affordable $299 price, its creators say it cleans floors quickly, efficiently and effectively.
According to Trifo, the Ironpie uses a combination of sophisticated visual sensors, processing power and software to achieve this. Additionally, the robot is designed to track its current position, plus remember where it has been previously.
As a result, the Ironpie should only vacuum areas it hasn't been, not spots it has already serviced. In fact, Trifo says the machine cleans "at least 10 percent more efficiently than competing robot vacuums". It's a bold claim, and one we'd love to put to the test.
