I absolutely love this Roomba vacuum mop

[This review was collected as part of a promotion.] This Roomba vacuum cleaner and mop is an absolute gamer changer. It has a home base that it automatically parks at to empty the dirty mop water when it needs to recharge. It spent about 20 minutes mapping out my entire house and I was able to easily block off a few areas with the intuitive mapping feature. It goes around and vacuums/mops everything and it's smart enough to detect carpet so it doesn't mop over your rugs or carpeted areas. It's much quieter than my old Roomba and it doesn't mop a great job moving around obstacles and edges. Overall this Roomba is going to save me so much time keeping my house clean from my kids and golden retriever!

Life and back saver

[This review was collected as part of a promotion.] I've been really impressed with this Roomba so far. The biggest standout feature is the dock that automatically empties the bin, washes and dries the mop pads. It takes so much work off of me to keep my floors clean. It does a great job of picking up everyday dirt and crumbs. Mapping feature was quick and accurate for my home. I love the easy scheduling feature which allows me to set it to clean while everyone is asleep. Overall it's a lifesaver!
