Review on SereneLife Robot Vacuum for Allergies and Stairs by Kristin Thomas

Actually this is my second robot vacuum; I have a big house so I made two vacuums to vacuum the house twice as fast. While my other has more bells and whistles than this one, I find it still gets the job done just as well. I liked another reviewer's suggestion of locking them in the bedroom so I did the same and it really worked! You might want an upgraded one with a longer battery that charges itself if you have more space, but I think it's great for a spare like me OR someone with an apartment or small house. Plus it's cheaper. I like sweeping the floors first and then running the vacuum, it amazes me how much excess dirt and hair this thing picks up. Love it!
