I’ve been skeptical of these things and have waited years for all the companies to work out their technical issues and all I can say is wow!! The shark 2-n-1 AI vacuum and mop is incredible.  We’ve got 3 big indoor outdoor dogs and have had to sweep twice a day and mop every day for years and now the shark takes care of it all.  It actually does it better than we could with a broom and hand mop, no streaks and no missed dirt piles.  I chose to pay the 6 payments which worked great with my Firefighter salary.  It doesn’t get stuck, it works around objects, self cleans its vacuum canister, and is extremely quiet.  We can run it in the middle of the night and not get woken up.
