    Detailed Test Results

    The Samsung Powerbot R7040 was exceptional in our carpet, bare floor and edge cleaning tests. The robot was even able to suck fine grains of flour from the carpet, another feat that some of the other models were unable to accomplish. The brushroll is a combination of a rubber blade and bristles which helped it pick up a variety of debris on the first pass. The front of the machine is squared off in shape which makes it possible to impressively clean the corners of our bare floors and carpets, something with which the rounder models struggle. Instead of traditional side brushes that most models adorn, this model has a shutter that extends down to capture dirt when the vac approaches walls. It edges methodically up to walls and corners and gets extremely close which explains its high Edges score. The design of the edge cleaning device also prevents scattering which many side brushes tend to do. It was able to navigate over most of our lab floors but it would not travel over the black matte carpet in the lab which reduced its navigation score. It was fairly gentle with furniture but did move some of the lighter items in the lab. It picked up pet hair quickly but most of the pet hair was on the brushroll and not in the bin. One positive is that the brushroll is easily removable and the bristles are shallow enough to make the hair removal easy. It avoided getting caught on the tassels of our rug and was quick to maneuver over electrical cords in our tests. We found that this model was quieter than its sister model the Powerbot R7070 on the max mode possibly because its motor is not as powerful as the R7070's. A few caveats: Its profile height is a little higher than other models and it may not clear under some furniture. On occasion, it took a few tries for it to transition to different surfaces but ultimatesly was able to climb over thresholds up to .75 inches. Features: Cleaning Modes: Auto, Spot, Manual, Repeat, One Time or Daily Schedule. Power: Turbo and Medium (normal). Special Cleaning Functions: Intelligent Power Control - automatically operates with stronger suction on carpet. Edge Clean Master - When it detects an edge or corner in auto or spot clean, it extends it shutter to clean. App: SmartThings version 1.7.51.42 allows you to check the status of the robot as well as schedule and view cleaning history. Battery: Li-Ion (21.6V, 80 W, 38.8Wh) Includes: It comes with a docking station, remote control and power cord. 1-year warranty.

    About

    The Samsung POWERbot R7040 is part of the Vacuum Cleaners test program at Consumer Reports. In our lab tests, Robotic Vacuums models like the POWERbot R7040 are rated on multiple criteria, such as those listed below.

    Carpet: Shows how much surface litter (cereal, rice, and peas) and embedded dust the vacuum picked up from a medium-pile carpet.

    Bare floors: Indicates the vacuum's ability to remove surface debris from a bare laminate floor.

    Navigation: A composite score that includes combined coverage over multiple runs, clearance under furniture and obstacle and entrapment avoidance.
