BISSELL SpinWave Wet, Dry Robotic Vacuum Cleaner 28599

[This review was collected as part of a promotion.] First off, I have 4 cats, and I am a clean freak. I purchased my first spin wave approximately 3 or 4 years ago and then decided I needed another one, I have a 2000 sq ft house all tile. But a month ago it seemed like the 1st one was only going about 15 mins on a charge, so I started looking around to see about getting another one, and on Bissel site they have this remanufactured spin wave, so I got that one also, but talked to one of Bissell help they told me that the old one just needed a battery and if that is not the problem I can always return the battery. I really love these spin waves I have all 3 going at one time, I love the mopping feature, it also vacuums at the same time, you would not believe all of the hair and keeps the dust off the floor. I have allergies, so I really need a clean house and when my husband asks me what I did today, well I mopped all the floors what more do you want me to do? I just pick up my phone and go to the app and just set all to go, they all find their way home, I am still figuring out how they know which bay is theirs, but they do, sort of scary on that one. I try to run these every day, might as well. Do I need 3, well no, but I like them that much. If anyone has any issues with these, they just have to read the manual or call Bissel help desk, they are great.
