The RoboVac by eufy is their own take on the modern cleaning machine – the robotic vacuum cleaner. Previously, I had the opportunity to do a review on the 11S model, and I’m following that up with the most recent model, the 30C, and the RoboVac 12. The 35C has a lot of improvements over the 11S and many other previous RoboVac models, and it isn’t just in suction power. The 35C has new smart assistant features, app-based controls, and it even has boundary strips so that you can keep your RoboVac on task, which will help keep areas cleaner, and use less power/battery to get the job done. It only seems to be a bit of an incremental upgrade over the 30C, but it’s far and away the best option when compared to other less powerful and dynamic versions, like the 11S and the 12.


What is it? The EUFY RoboVac 35C is the latest and greatest – and most powerful – RoboVac ever made, and it’s really quiet for a vacuum cleaner. Not only does it have more suction power and more ways to control it, but they’ve also decided to include app support VIA the EufyHome app, which can be installed on Android or Apple devices, which allows you to control the RoboVac from your device, as well as setup cleaning schedules for the vacuum. Reigning in at 2.85” of clearance height, you can also fit this guy under just about any piece of furniture with legs on it. Additionally, Eufy decided to make an additional technological leap, adding Google Assistant and Alexa support so that you can control your RoboVac just be speaking a few words. Simply say “OK Google, tell RoboVac to start cleaning.”, and it will get to work! They also increased the battery power to support up to 100 minutes of continuous vacuuming!


What Comes in the Box:
- Of course, the RoboVac 35C
- An extra high-performance filter
- 2 sets of bristles that attach under the RoboVac and spin while it cleans
- The Remote control (complete with two (s) AAA batteries)
- The instruction manual
- The charging base and cord
- A bristle brush for cleaning the sweeper.
- (1) 6.5ft boundary strip
- (1) pkg of 3M double-sided tape strips to install the boundary strips


How does it work: The RoboVac 35C is controlled by handy dandy wireless remote, through the Eufyhome App on Android or Apple devices, or by using Google Assistant or Alexa voice commands. The primary modes are: spot cleaning, edge cleaning, single-room mode, and auto. Here is a brief description of the modes:

- Spot Cleaning: In this mode, the RoboVac starts at whatever point you start it at and goes around in a slow concentric circle, getting wider as it drives around thoroughly cleaning the designated area. This cycle last for two minutes, and then the RoboVac stops.

- Edge Cleaning: In this mode, the RoboVac drives until it finds the nearest wall-surface, and then it bumps and moves along the edges for 20 minutes, which is more than enough time to clean the corners and edges of pretty much any sized room. Once it’s done the RoboVac automatically heads back to the charging base to dock.

- Single-Room Mode: This is a combination of angles and edges, as the RoboVac drives around from corner to corner, or in various directions for a period of 30 minutes, which is ample for most sized rooms. Once it’s done the RoboVac automatically heads back to the charging base to dock.

- Auto Mode: In Auto Mode, the RoboVac optimizes its cleaning path by selecting different cleaning modes automatically until cleaning is complete.
Additional Control Options:

- Charge Mode: The RoboVac will head back to the base station to charge.

- Fan Speed: The fan speed button allows you to set the amount of suction power that the RoboVac uses. The mode will be indicated by the number of audible beeps when you hit the fan speed button.
o One Beep – Standard Suction
o Two Beeps – BoostIQ mode (automatically adjusts the suction power as needed)
o Three Beeps – Max Suction


What’s New: First and foremost, the RoboVac has voice support now. You can use your Google Assistant or Alexa enabled device to control the RoboVac. All you have to do is say “Ok Google” or “Hey Alexa” followed by “Ask RoboVac to start cleaning”, or “Ask RoboVac to stop cleaning.” – It’s really quite a novel feature that helps make cleaning even that much easier, and it’s really also kind of a pain in the rear end to set it up. However, it is pretty responsive and can even be told to return back to the charging dock by saying “Hey Google, ask RoboVac to return to charging base.” Second, the RoboVac has an app-based controlled now. You can download the EufyHome app on your Apple or Android device, so that you can use it to control the RoboVac. The App also allows you to setup cleaning schedules for your RoboVac. There is an option for each day of the week, where you can preset a time for the RoboVac to start cleaning. However, this is a bit limited because it only allows you to set one time per day, and you can’t preset a mode. It will automatically enter the last cleaning mode that it was used in. Last but not least, the 35C has a boundary strip. The RoboVac comes with one (1) magnetic boundary strip, along with some 3M double-sided tape, that you can install anywhere you want to keep your RoboVac from running off. You can cut it up or install them pretty much anywhere you want so that you can keep your RoboVac on task. It’s a nicety but it really is unfortunate that they don’t send more strips with it. If you need more then you’ll have to order them on the internet.


Does it work: Yes! And it works well. The 35C has tons of suction power and a wide variety of cleaning options to ensure that your home or office is nice and clean – granted you keep the floor tidy and free of objects and cords. The RoboVac can only clean as well as your house is actually cleaned. So, don’t expect to drop this thing in your kids’ room with toys everywhere and then be disappointed that it didn’t pick up all of the Legos. However, if you do your part and keep everything tidy and in order, the RoboVac will help save you time and leg work by doing the vacuuming for you! Not only is it good for routine cleaning and picking up dust and dirt, but it can also do some heavier lifting in the event that you drop small debris, trash, crumbs, etc… on the floor. The suction power and robust BoostIQ mode, has up to 1500Pa of suction power on demand, which works extremely well in conjunction with the side brushes, that help sweep objects into the suction area for pick-up. As long as you keep your floors relatively clean and use the RoboVac often, it‘s a great option for your home cleaning arsenal! I did recently find that it has some slight mobility options in thick/dense carpet though. On hard surfaces it maneuvers like a champ, but even with it’s raised wheel base and all of it’s power, it can have some difficulty turning around or maneuvering obstacles in heavily carpeted areas. It never got stuck, but it wasn’t as snappy as it was on the hard surface.


Hang-ups and Shortfalls: Probably the biggest shortfall of the RoboVac is that it doesn’t map the room as it cleans it. Sure, it’s not the end of the world, but it a) takes longer, and b) is less thorough than it’s more intelligent counterparts; however, you are saving a bunch of money with the RoboVac. Another source of irritation is the magnetic strip. It doesn’t work with carpet so well because you can’t tape it to the carpet fibers. I recently upgraded my living room to carpet from wood, and now I can’t use the magnetic strips that helped zone it off and clean the main area of my living room. Finally, It doesn’t get stuck too often, but it doesn’t like things with ramps like pedestal fans. It also doesn’t’ like cords – actually, I should probably say that it does like cords… it tries to suck them up. So… PSA, make sure your cords are wrapped up and tucked away neatly so the RoboVac doesn’t run over them. Another shortfall with the RoboVac is the setting up the daily schedules. You can set a schedule each day or the RoboVac, but you can’t set the mode, and you can’t set more than one time. You are limited to selecting a single time and the mode that the RoboVac uses will be the last mode the RoboVac was in prior to docking – kind of annoying. Hopefully the next model will allow you to set multiple schedules and specific modes. Last but not least, the Wi-Fi connection only supports up to 2.4Ghz connections, which is pretty common, but still unfortunate. Thankfully my router supports both 2.4Ghz and 5Ghz connections (my primary is 5Ghz), which means that if I want to control the RoboVac through the phone app, I have to leave my phone connected to the 2.4Ghz Wi-Fi connection. It’s not the end of the world, but it can be inconvenient if you like to life your life on 5Ghz when you’re at home.


Conclusion: The RoboVac 35C is a slight refresh of the 30C unit. It has the same amount of suction power and largely the same capabilities, but it does seem to be snappier and it looks sharp. The app and voice command functionality are the same, the boundary strips work the same and it has the same 2.85” of clearance height. If you can find the 30C on sale, I would likely recommend it over the 35C, but if you want to spend the few extra dollars, you’ll be getting the latest flagship model that has battery for days, great suction power and works well in most any situation. I would check the sales and see if you can find them on sale and weigh your options to figure out which works best for your home, and your wallet.

pretty much just the design and the voice prompt features - 30C doesn't have the voice enabled prompts,
but it does allow you to drive it with the app. Annoyingly, the 35C comes with 7ft less of boundary strips than the 30C.
