Continuing with our series on low and mid-level robot vacuums, we are reviewing the Samsung Powerbot R7040.


We put it through a lot of tests, and this video will be the results and our review. Links above for current prices and reviews.


First, let's look at the pros.


The Samsung R7040 is a budget version of the wifi enabled powerbots from Samsung, but it has some hardware and some features that you typically only see on high-end robot vacuums. For example, it has a camera and a suite of front-mounted sensors that combine to make it really advanced when it comes to navigation. More than half of the of the robot vacuums we are testing in this price range are dumb navigation bots, meaning they randomly bounce around to clean your home, but the R7040 cleans in efficient straight lines, which saves a lot of time and battery life.


It was particularly methodical, and it did, indeed, cover the entire area (even in the obstacle course) with no major missed spots. Its full view sensors also did a good job of reducing the force with which it bumps into things, but there were instances where it couldn’t see things outside of its sensors' range, and it did bump them harder.


In general, I would have to say that so far the Samsung R7040 is the best budget robot we have tested with regard to navigation and its obstacle avoidance algorithm, but it might have competition with the next one up in the series. 


Another pro is its mechanics. It has a front-mounted super-wide brush roll which gives it a very large cleaning path width. It doesn’t have a side brush but instead uses its D shape and its very interesting so-called Edge Clean Master to clean edges. This is a rubber blade that extends to clean corners. I should mention that in our edge cleaning test it didn’t do that great, but this was probably due to our test floor having a quarter-round moulding instead of a 90-degree angle, so that’s something to keep in mind.


Another pro was that it, so far, is the only vacuum we have tested that had its exhaust on the top, meaning it didn’t blow around light debris (like pet hair) on hard floors like so may others do. This, combined with not having an edge-cleaning brush which tend to scatter debris, makes the powerbot one of the least messy robot vacuums in terms of cleaning. It doesn’t sound like a big deal, but it's more rare than you might think.


It also comes with a really handy remote control as well as the mobile app. I actually much prefer using the remote for basic tasks like starting and stopping, changing power modes, or selecting spot mode, which causes the bot to clean in a spiral pattern wherever you place it. You can also use either the remote or the app to control it much like a remote control car, which is pretty cool. The app is needed for scheduling cleanings or checking the history or the maps of where it cleaned that day.


The next few things are not really pros or cons; they are just kind of neutral.


The power was about average. As the budget version, it’s the only powerbot in the 7000 series to have 10w instead of 20w. We measured its airflow and found that it has 9 CFM on low power and 11 CFM on high power. So, it's not great but not bad either. For comparison, the budget Roomba, the 690, only had 7 CFM on its one power setting. So, if you look at it that way, the R7040 is more powerful than the equivalent Roomba even on its low power. Despite having just average power, it actually did much better than average on the crevice pickup test, which I chalk up to a well-designed seal on the brush surface.


Its pickup ability on carpet was about average. It picked up all the debris, from fine debris to pet hair and even extra large debris, with no issues. I did find that high power was better but not much of a difference as even in low power it picked up all the debris.


On hard floors, there are a few things to note. While it also picked up all the debris in its low power, I found that there were a tiny bits of debris left. On high power, it did a lot better, so, I would say that on hard floors, high power is the setting to use.


Another issue with hard floors is that because the Samsung Powerbots ride a little lower to the ground that most robots, it struggles with extra large debris like the Fruit Loops and large clumps of pet hair. It's not a deal breaker since its only rarely going to be an issue in the real world, but it was not as good as the others we have tested in this regard.


Its battery life is 60 minutes on low power, but we tested it at only 40 minutes on high power, which is the lowest amount I've seen so far. The silver lining is that because it is a smart navigation bot with a camera, it has recharge and resume so when its battery is low, it returns to the base to charge and then starts again where it left off. So, effectively, the battery life is irrelevant or, at least, much less important than with a random navigation bot where you need a lot more battery life to ensure it cleans the whole house.


Moving on to the cons.


The dust bin is pretty small at 0.3 liters, though we measured it a 2 cups which is actually not that bad - double the size of the Roomba 690, for example. But the real con here is that you have to basically take the entire mechanism apart to empty it. Its not a huge deal or anything, but it seems a like an unnecessary hassle.


It may be a little unfair to call out its carpet deep cleaning ability since robot vacuums are bad at this across the board, but in our embedded sand in the carpet test, it only scored 64%. Again, not as bad as the Roomba 690, but pretty close.


It's also probably not fair to point out that it can't clean black carpet because almost no robot vacuums can, as their cliff-detection sensors think it is a drop off, but there it is.


At 3.8”, it’s a little too tall to get under too many couches or other furniture, which is too bad as having a robot that can clean under things like couches is one of the great reasons to own one.


It also does not come with any barrier features on the app, nor does it include any physical barriers like magnetic tape or a virtual wall barriers in the box. Not a lot of people use them, but if you had an area that you didn’t want the robot to go that you couldn’t block off by other means, it could be an issue.


So, on the plus-side, the Samsung Powerbot R7040 is one of the cheapest camera-equipped smart navigation robots you can buy, and its navigation and sensors are one of the most high-tech I have seen. It has some really ground-breaking features. It has good cleaning mechanics and decent power, but it's not without its quirks.


All in all, I think the R7040 is a good deal at the price it's at, but I suspect the next vacuum in the series will have it beat in several ways, so be sure to subscribe to Vacuum Vars for that video.
