Eufy Robot Vacuum 3-in-1 E20 Review

The vacuum has high-performance filters and uses Lidar navigation with ultra-wide front scanning and smart obstacle avoidance. Easily control it using the companion app, which also maps your home room by room. Once it’s done, the robot vacuum dutifully returns to its charging dock, which also has an auto-empty function.

There’s no direct comparison to this unique machine, but it is a single, affordable unit that replaces the need to have a robot vacuum and a cordless vacuum. It performs best as a robot, while the stick is handy for hard-to-reach spots and quick cleans.

The Eufy 3-in-1 E20 is a robot vacuum and cordless stick vacuum-in-one that also functions as a handheld vacuum. It works with a variety of optional accessories and comes with a floor brush cleaning head, a 2-in-1 combination tool, and a crevice tool.

With powerful suction, including turbo modes, it can pick up all types of debris using the anti-tangle comb teeth. Thanks to Lidar navigation, the robot can intelligently map your home and conveniently avoid objects on the floor, including furniture, as well as items as small as 15mm, like a rogue piece of LEGO your child left under the couch.

Use the intuitive companion app to control it, manage maps, adjust settings, and more. Once has completed a cleaning cycle with the robot vacuum, it auto empties into its docking station, which can store up to 75 days’ worth of dust and debris. Remove the bag, clip in a new one, and you’re good to go.

How we tested

We tested this vacuum in a traditional home setting, letting it run on hardwood floors, tiles, and a living room carpet as well as carpet runners and front and back door mats. We used both the robot vacuum, letting it scoot about on its own, as well as the cordless stick for manual passes and quick clean-ups. We also used it as a handheld to clean corners, baseboards, and furniture. We tried all modes, including Eco, Standard, Turbo, and Max as well as x2. Using the app, we mapped the main living area of the home, naming the rooms and running both full cleans and room-specific cleans. To compensate for not having pets in the home, we used human hair pulled from a hairbrush, leaving it in clumps and broken apart into both medium and large sized pieces to mimic all types of pet hair.

The vacuum was used periodically for daily and weekly cleans over several weeks. Along with regular maintenance, we simulated common spills, including cereal bits, coffee grounds, and other small and large particles.

What we like

The design is incredibly versatile

How can you go wrong with a vacuum set-up that includes both a robot and a cordless stick? Dubbed as the “world’s first” of this type, it’s a design that makes total sense. We have always recommended having at least a cordless stick vacuum alongside a robot vacuum to handle those hard-to-reach places that a robot can’t get to on its patterned runs. This system combines both in a single package, affording fantastic value, especially for its price.

We love that you can set the robot vacuum to clean the floors of your entire home, lifting it from one floor to the next if you live in a multi-level home. Pop out the motor and dustbin, click it into the cordless stick with the floor brush cleaning head, and finish the job. It’s so convenient and both vacuum types work well on flooring and carpets.

While you might not get the same power—especially from the stick—that you’d get with other cordless stick vacuums, it does the trick for smaller homes and touch-up maintenance cleaning.

Mapping and the app are great

After just a few passes, the robot vacuum was able to map a small main living area that consists of a hallway, living room, dining room, and kitchen with plenty of obstructions in the way including objects, furniture, walls, and even a landing with a slight incline. It navigated everywhere with ease, intelligently turning away from rogue objects or furniture without bumping into them first, which is something we have seen other robot vacuums do from time to time.

The companion app is intuitive, showing an easy-to-read map of the home where you can rename rooms and select individual ones to clean, like just the kitchen after a spill or just the dining room after your dinner party. You can edit the map if you want to merge two rooms, for example, so it always cleans the kitchen and dining room together. Divide larger rooms, create no-go zones, and even indicate where there’s carpeting and the type of carpet to ensure optimized cleaning everywhere.

Check the charging status in the app, select modes, and even select zone cleaning, like under your toddler’s high chair after a meal. It’s also compatible with Amazon Alexa, Google Assistant, and Siri, so you can control it with simple voice commands.

It expertly avoids objects

While the robot vacuum did pick up a rogue cable from the floor that we had to unwind from its roller brush, that was user error. In fairness, the instruction manual does clearly state to pick up cables before running the machine. So, you’re best to clear the area of cords before running a pass.

With that said, the robot vacuum nicely avoided smaller objects on the floor, like shoes and socks. Even when people were standing in its way, it re-routed to avoid slamming into human feet. It never once knocked into a wall or piece of furniture and navigated the best, most logical route back to its dock every time.

With a slight incline from the dining room to the kitchen that some other robot cleaners haven’t been able to scale, it did so with ease. Dare I say it performs just as well as some high-end iRobot Roomba options, including models we named among the best robot vacuums.

The robot vacuum operates ultra-quietly

The first thing we noticed with this robot vacuum is that even in Turbo mode, it’s quieter than most others, something we have observed with other Eufy robot vacuums as well, like the Eufy Robovac 11S and the Robovac 11+. This means you can easily run it in the background while you’re taking Zoom calls or even while watching TV without worrying that it will be too distracting.

It should be noted that it does also provide audible guidance, indicating if it’s charging or has run over an object and is not touching the floor. It’s both futuristic and useful.

Keep in mind that the robot vacuum is louder when emptying, but this is only a few seconds after each clean. In terms of operating sound, including with the cordless stick vacuum, you’ll appreciate that it’s fairly quiet.

What we don’t like

There’s no place to store the stick

The robot vacuum sits neatly on a dock, its removeable motor tucked inside. The dock has a convenient storage compartment for the dust bag, and it recharges the robot vacuum when it automatically returns after cleaning. The crevice tool even neatly fits into the top of the robot vacuum for storage.

However, when it comes to the cordless stick portion of this unit, there’s nowhere to put it. Eufy does offer an optional wall mount bracket that we wish came in the package. Otherwise, you need to either prop the cordless stick up against the wall beside the robot vacuum and its dock or toss it in a closet or cupboard to pull out as needed. If you plan to use it daily, we’d suggest investing in the bracket for a neater set-up.

The robot vacuum sometimes needs a few passes to get all the debris

The robot vacuum portion of the unit works comparably well compared to other top models from competing brands, navigating the home around obstacles and getting into every nook and cranny. However, with very dirty areas, it may take a few passes to everything.

After a big cereal spill (as luck would have it, it was legitimately accidental), the robot vacuum did its thing, chomping on the pieces like Pac-Man devouring its next meal. It did end up missing several areas or just pushed around the larger (about one inch) cereal pieces. Switching to Turbo mode and running it again sufficiently finished the job.

If you have a larger home, expect to need to run a few passes, with charges in between. With the scheduling tool in the app, however, you can set this to run while you’re away to return to freshly cleaned floors.

It does a decent job picking up debris like hair, which we littered on kitchen tiles and a living room carpet. It picked it all up with ease, though larger pieces did wrap around the roller brush. It’s not the best robot vacuum you’ll find for pet hair, but does a good enough job and is worth considering if you have a pet that doesn’t shed too much.

One thing worth noting is that the robot vacuum occasionally folded up the edges of a thin carpet runner, so it’s best to fix the edges to prevent this.

Stick vacuum isn’t as powerful as others

As the saying goes, sometimes when a product (or person) can do more than one thing, it’s considered to be a jack of all trades but master of none. That’s sort of the case with this setup.

While the robot vacuum is wonderful, a tremendous value at half the price of some high-end competitive models, the cordless stick vacuum is sort of an afterthought. It doesn’t feel particularly durable and it isn’t as powerful as other dedicated cordless stick vacuums on the market. It’s perfect for quick clean-ups of moderately dirty surfaces, and we love that the handle is adjustable to accommodate differing heights.

It’s also easy to connect optional attachments for cleaning everything from carpets to baseboards, even take it out to the car. (We even used it with the crevice tool to clean crumbs from the top of a toaster.) But it doesn’t replace a more powerful stick vacuum, and won’t be powerful enough for households with pets that shed a lot.

With that said, if you can rely on the robot vacuum to do most of the heavy lifting, the cordless stick will suffice for touch-ups, daily passes through high-traffic areas like the hallway and kitchen, and tackling stairs, furniture, and blinds.

Just know that the cordless stick is a secondary feature to the primary robot vacuum set-up.

It uses replaceable bags

The one thing people dislike about traditional vacuums is the need to buy replacement bags. While the bag in the dock can hold up to about 75 days’ worth of dust and debris, it will need to be removed and replaced once it’s full, which means having a supply of bags on hand, at least three per year. This results in added costs for consumables. There are bundled purchase options, one of which includes three extra dust bags to get you through the first year.

Otherwise, you can find the bags in multi-packs to stock up and be set for a year or two at a time. But this recurring cost will be necessary for the span of time you own the vacuum. It’s wise to add at least one multi-pack to the initial purchase and keep track of inventory when you’re down to the last one so you can re-order through the life of the machine.

Warranty

The Eufy 3-in-1 E20 comes with a 12-month warranty when purchased from an authorized seller along with a 30-day money-back guarantee for any reason when you order it through Eufy.com or the Eufy Store on Amazon. If purchased from a local retailer, you can contact the retailer to learn about its refund policy. Typically, you will be asked to return the vacuum when submitting a warranty claim so that Eufy’s Quality Assurance team can analyze the defective product.

What owners are saying about the Eufy 3-in-1 E20

User comments about the Eufy 3-in-1 E20 generally express that shoppers are happy with its performance, including the versatility of the device, its effectiveness in picking up dust and debris, and intelligent mapping. We’re pulling these user reviews from the Eufy website, Amazon, and Best Buy.

• Eufy store: With an aggregate 4.84 stars from buyers, they love that it’s easy to use, lightweight, and a breeze to set up. They appreciate the intelligent mapping and how you can conveniently clean just a specific room when desired, even setting no-go zones for areas with plants or delicate furniture, for example. They also love how efficiently it unloads dirt and debris into the bag once docked.

• Amazon: With 4.2 stars, Amazon shoppers love this dual vacuum set-up. While some say it doesn’t work as well on carpets as hardwood floors and tiles, they love the mapping feature and how quiet it is, though they wish the emptying process was quieter. They appreciate the convenience of the cordless stick, which does a great job, but note that it doesn’t perform well for pet hair. Some feel the self-emptying doesn’t run long enough, resulting in not all the dirt and debris being picked up in every go. (There is, it should be noted, a deep dust collection option in the app that will suck up debris more powerfully, running both louder and longer).

• Best Buy: Shoppers find the vacuum powerful, fast charging, convenient, and space-saving since it is essentially two vacuums in one. However, they’re not as pleased with the replaceable bags, which require additional ongoing purchases. They would prefer a dustbin that could be emptied and washed instead.

Overall, most customers love this robot and cordless stick vacuum combination device, the ease of use of the companion app, accurate mapping, and thorough cleaning. Shoppers are divided on how well it works for households with pets. Many wish that the dustbin was washable versus requiring bags.

Should you buy the Eufy Robot Vacuum 3-in-1 E20

Yes, a good option for smaller homes and apartments

The Eufy 3-in-1 E20 (available at Amazon) , a CES 2025 Best of Innovations Awards recipient, is a good option for smaller homes. You can keep up with weekly maintenance using the robot vacuum while the cordless stick is sufficient for supplemental cleaning in hard-to-reach places or quick cleans of unexpected messes.

If you have a larger home or one with pets, you may want a more powerful cordless stick vacuum to go along with the robot vacuum. However, it’s so convenient to be able to accomplish both tasks in one package, and the design is heavy on the cool factor. With that said, we’d recommend buying the mounting bracket for the cordless stick along with an additional supply of dustbin bags, factoring in the cost of both for a more realistic total cost.

If you’re considering a robot vacuum, the robot vacuum itself rivals others on the market, even ones that are more expensive. The mapping is accurate and the robot follows a logical path to achive its goal. Features like customized cleans, no-go zones, scheduling, and object avoidance, are all appreciated. The cordless stick is a nice-to-have alongside the robot, even if you already own a more powerful cordless stick vacuum. For smaller homes and apartments, you might find the Eufy 3-in-1 E20 vacuum the perfect option at an affordable price considering you get three vacuums in one.
