We love this vacuum. We’ve had it for a few months and run it every night while we sleep. It navigates well. Occasionally it gets stuck on something but it is easy and straightforward to fix. We have mixed surfaces and stairwells to avoid, and it does it all very well. Love that it isn’t connected to the internet. Just keeps it simple. We empty it every morning and with 6 kids plus lots of extra people in our home, it always has plenty to clean!
