I let it run and clean my house once a day and my allergy is almost gone. I have two cats and Neato collects all the hair form the carpet. I ordered extra filters and just throw them into the wahsing machine. The magnetic tape does not work very well, so I got foam pols for the pool and use them to block the areas where I don't have carpet and don't need cleaning. The vacuum is expensive but for me it's a great help.
