I use this as a barrier for the Shark IQ robot vacuum cleaner. The vacuum cleaner itself works just as well as my Roomba which cost 2 1/2 times the price but broke after 3 years. This magstripe shark barrier works well enough but looks crumbly and I really don't want to put it on and pick it up every time I vacuum. The infrared barriers (I think) that Roomba uses are superior to this method because they're out of sight, out of mind (by comparison) and the batteries last for many months. "So everything in life is a compromise," including the shark vs. shark game. roomba Functionally, I can't complain about these magnetic barrier strips, but aesthetically they leave a lot to be desired.
