Budget robot vacuums can be hit or miss. It takes a balance of suction, navigation, cleaning ability, and functionality, which can be difficult to achieve. With the G40+, Eufy set out to match a budget price with one feature usually reserved for more expensive robot vacuums: a self-emptying charging dock. In this Eufy RoboVac G40+ review, we’ll go over all its features, pros, and cons.
UPDATE: The G40+ is currently out of stock on Amazon. In our opinion, the closest Eufy model is the G30 Hybrid Plus, which mops and features a self-empty dock. Links in this review will direct to that product until the G40+ is available.

Eufy RoboVac G40+
For those unfamiliar with the brand, Eufy is a leader in budget robot vacuums. With the RoboVac G40+, they have taken their tried-and-true slim robot vacuum design and added many performance upgrades, navigation enhancements, and features.
The plus in G40+ indicates that one of its features is an auto-empty dock, making it one of the few Eufy models to offer this.
Eufy currently offers two variations of the G40. The first, and the one in this review, is the Eufy G40+. We picked one up and have put it through a handful of evaluations to measure its performance. We’ll cover those findings in this review.

The second version also ships with the auto-empty dock and can both vacuum and mop floors. That model is sold as the Eufy G40 Hybrid+. Eufy priced both of the models affordably, not just the vacuum-only option.

Unboxing and setup
When the G40+ we bought arrived, we charged it up and connected it to our Wifi network. Once the battery was topped off, it was time for evaluation.

Performance and evaluation results
Eufy’s website states that the G40+ has 2500 Pa of suction, which falls within the range of most robot vacuums in its price range. For comparison, Roborock’s high-performing S7 robot also had 2500 Pa of suction. It has since been trumped by the S7 MaxV Ultra and S8 Pro Ultra.
Vacuuming carpets and hard floors
As far as its primary job of picking up debris from the surface of hard floors and carpets, the G40+ was excellent. It picked up everything from fine to extra-large debris on hard floors and carpets without issue.
It also put its suction and airflow to good use in our crevice pickup evaluation. It was better than average overall, and much better than other budget robot vacuums.
We’ve always been impressed with Eufy’s robot vacuum pickup mechanics, and the G40+ proved to be no exception.
Deep cleaning
One area where the G40+ performed below average when compared with over 70 other robot vacuums we evaluated is in our carpet deep cleaning evaluation. In this assessment, sand is embedded deep into a medium pile carpet. We then set a robot vacuum to clean the carpet, weighing its dust bin before and after to determine how much sand it was able to extract.
Top Robot Vacuums
The G40+ scored a 69 compared with the average score of 75. Of course, this evaluation wasn’t limited to robot vacuums in the same budget range. For comparison with other Eufy models, the RoboVac G40+ scored about the same as the Eufy 11S or 30C models.
However, before rushing out to buy the much cheaper 11S, consider that the 11S cleans randomly, unlike the precise, row-by-row method used by the G40+. It can’t empty itself, either.
At the end of the day, we don’t think it’s that big of a deal, and the G40+ does excel with surface debris, as we mentioned.
Battery life, recharging, and resume
The Eufy RoboVac G40+ has a manufacturer-quoted maximum battery life of 100 minutes. That’s less than 120 minutes, which is the average run time across 70 robots we’ve evaluated.
But the G40+ does have Recharge and Resume. Recharge and Resume is pretty much what it sounds like. When the battery becomes nearly depleted, the robot returns to the dock, recharges, and then resumes cleaning where it left off.
Those with a larger home or who prefer to run their robot vacuum on its highest setting most of the time should take note of this.
Features
There are many robot vacuums on the market today, and they generally share a good cross-section of features and capabilities. The Eufy RoboVac G40+ has a few features we want to call attention to if you’re considering it.
Auto-empty bin
The auto-empty bin that comes with the RoboVac G40+ was a high point in our evaluations. Auto-empty bins are becoming increasingly popular, and when they function properly, they are a great addition.
When our G40+ returned to its charging base after cleaning, it would automatically empty the robot’s dust bin into a disposable bag, which is inside the auto-empty bin. In our evaluations, the robot docked and emptied itself without any issues, and there were no clogs.
Eufy’s auto-empty dock is also a manageable size, making it much easier to find a place for in a home than larger docks, such as the one that ships with the Ecovacs Deebot X1 OMNI. We think the G40’s dock is reasonably sized — comparable to the docks for other vacuum-only robots.
The bags are 3.2L in size, and the G40+ comes with two of them. Eufy’s website states you can expect not to need replacements for 60 days. Of course, how often that will be is really determined by how often the robot is run and how much debris there is for it to clean up.
For homes with a large area to clean, or those with pets that shed, we recommend setting the G40+ to empty its bin after each cleaning run to prevent it from becoming overfull or clogging during emptying.
App
The Eufy Clean app is used to set up and then control the G40+. The main features are creating maps, setting the robot vacuum’s suction level, and creating cleaning schedules.
The App is also where you can turn on or off Boost Mode. When enabled, the robot vacuum automatically adjusts the suction for carpets. We highly recommend Boost Mode and were happy to see it included in the G40’s list of features.
Low profile design
At just 2.85 inches tall, the G40+ is much shorter than the average robot vacuum. How much shorter? The average height of the robot vacuums we’ve measured is approximately 3.36 inches tall. That’s just over a half-inch of extra clearance.
This means it can clean under a lot of furniture that other robots simply can’t.
Navigation
One significant advantage of the Eufy RoboVac G40+ was its ability to navigate around the house. Unlike less expensive Eufy robot vacuums (and cheaper robot vacuums in general), it creates a map of the home and then navigates in a systematic, row-by-row fashion when cleaning.
While more expensive robot vacuums have laser or LiDAR-based navigation, the G40+ uses a gyroscope and a floor tracking mechanism. This method of navigation is considered a middle-tier option for robot vacuums. Eufy is also using this on another budget robot, the Eufy RoboVac G30, which has slightly less suction power and lacks an auto-empty dock.
The gyroscope and floor tracking mechanism type navigation is much more efficient than cheaper robot vacuums that bounce around more or less randomly and don’t create maps. But while it is much better than those, it isn’t quite as accurate as robot vacuums that map with lasers or cameras.
We’ve always been impressed with Eufy robot vacuum pickup mechanics and the G40+ proved to be no exception.
However, if you had to place the Eufy G40+ somewhere between the two navigation methods, it would be far closer to the accurate mapping of those much more expensive robot vacuums with more sophisticated systems.
In our evaluations, we found it to be really good at navigation. Its coverage was nearly 100%, and it was very efficient. It was able to map out a 400 square foot floor plan on its first try. It then continued on to clean the entire space in about 60 minutes, which is about as good as vSLAM or LiDAR-based robot vacuums we’ve evaluated.
It made good decisions in tight spaces, though we still recommend picking up as much clutter as possible before running it to avoid issues.
Eufy RoboVac G40+ review: value and recommendation
The Eufy RoboVac G40+ offers considerable value. It’s one of the cheapest auto-empty robot vacuums in this price range. It performed well in our evaluations, and customer reviews have been very favorable so far.
In general, we were really impressed with the Eufy G40+. It’s a good budget auto-empty vacuum with a ton of power, excellent performance, and impressive pickup ability on both carpets and hard floors. Additionally, it offers surprisingly good navigation and features for the price.
