Hands down, this vacuum has been a life saver. Our house is 4 floors and 3000sq feet- all hardwood and many area rugs, which means I spend way too much time vacuuming...With a large family and 4 kids, I had to vacuum my kitchen after every meal. Crumbs and dirt would stick to the bottom of my feet( which I can’t stand!) and even though I’d clean the floors with our Shark vacuum- it still didn’t get everything!? I would spend another hour each night doing our area rugs and high traffic areas...Since purchasing the Roborock vacuum a month ago, I literally go on my phone and tell the vacuum to clean... that’s it!!! I run it 2-3x a day on our main floor and rotate use around the other floors whenever it’s needed. It goes under furniture. It easily gets under our table, and cabinets and it’s little sweeping arm gets the smallest crumbs. It can climb over thresholds to get in another room, and it even powers up to a higher suction when it is cleaning the area rugs! Best of all I’ve told my kids if they don’t clean up their toys, the robot vacuum will suck them up forever... which means they are cleaning their toys up too! Over all- Win win!I don’t know why I waited so long... I can’t imagine our crazy life without the Roborock Vacuum!
