eufy RoboVac 25C Robot Vacuum Review

Build quality is reasonably sturdy. The vacuum is mostly made from hard plastic. Unlike the eufy RoboVac G20, which has a glossy-finish top cover, the 25C has a matte-finish cover with a dimpled surface. It doesn't feel especially fragile overall, though it still has a somewhat cheap overall feel compared to pricier models in eufy's lineup, like the eufy RoboVac X8. It's most apparent after removing the dirt compartment under the vacuum.

The vacuum isn't too hard to set up, as its side brushes, brushroll, and brush guard fit into place quite easily. Its filter assembly is finicky to take apart and put back together, as it's made of three separate components.

There are quite a few parts that need periodic cleaning.

• Dustbin: You can remove the dustbin pretty easily by pressing the release button and pulling it free. You should empty it after each cleaning session. You can use the included cleaning tool to cut away any stuck-on dirt and debris.
• Brush guard: You can easily pull the brush guard from its housing. You should remove any stuck-on debris from the brushguard once a month.
• Brushroll: You can access this part by removing the brush guard and pulling the brushroll free of its housing. According to the manufacturer, you should clean it once a week. It's worth mentioning that long hair tends to get caught in the brushroll, so you should use a pair of scissors to cut it away when necessary.
• Filter assembly: The filter assembly is in the dustbin lid and comprises three parts: the foam filter, the high-performance filter, and the pre-filter. You should clean all three filters once a week with the included cleaning tool. Be aware that pulling off the pre-filter screen can release a plume of fine dust.
• Side brushes: You can simply pull the two side brushes out of their sockets. Long hair can get stuck in these components. You should clean them once a month by hand or with a damp cloth.
• Swivel wheel: You can remove the swivel wheel from its socket. You should clear it of stuck-on debris or tangled hair once a month.
• Motorized wheel: No specific maintenance interval is given for the motorized wheels, but you should still remove any tangled hair or stuck-on debris whenever necessary.
• Sensors/Charging Pins: You should clean the sensors and charging pins of any stuck-on dust or dirt with a clean cloth or cleaning brush.

Recurring costs are somewhat high.

• Filter assembly: According to the manufacturer, you should replace the filter assembly every two months. A six-pack of replacements can be purchased here.
• Side brushes: You should replace the side brushes every three to six months or whenever you notice visible wear and tear. A four-pack of replacements can be purchased here.
• Brushroll: You should replace the brushroll after six to 12 months of use or whenever you notice that it looks worn. A replacement can be purchased here.
• Brush guard: You should replace the brush guard when the rubber strip is visibly worn. A replacement can be purchased here.

A replacement parts kit, available on eufy's Amazon store page, contains:

• 3x Filter assemblies
• 4x Side brushes
• 1x Brushroll

This vacuum is very easy to store. Its overall dimensions are almost identical to those of other models in eufy's lineup, like the eufy RoboVac G30. Its charging dock is also very compact and you can easily set it up in small gaps between furniture.

The eufy 25C's dirt compartment is small. There's no built-in fill sensor to alert you when to empty it through its companion app, and since there's no max fill line, it's hard to tell how full it is at a glance.

Range is limited only by the room left in its dirt compartment and the remaining battery life. That said, this vacuum can't climb or descend stairs.

This vacuum is very portable. It weighs less than other similarly-designed robot vacuums like the eufy RoboVac G30, making it easier to carry from room to room.

Battery performance is excellent. The eufy can run for over 100 minutes in its default 'Standard' power mode and has a runtime of roughly one hour in its high-power 'Max' mode. It's very similar to the eufy RoboVac G30, but thankfully, the 25C charges much faster. While the battery indicator light on the vacuum doesn't give you a precise measure of the remaining charge, it does start to flash orange when it's low in power. The light flashes blue when the vacuum returns to its charging base, transitions to pulsing orange when it's charging, and turns solid blue once the battery is fully charged.

Make sure that the side brushes are out of the way when the vacuum is on its dock, as the brushes can cover the charging pins and cause the vacuum to report incorrect battery status info.

This vacuum has a couple of quality-of-life features. There are three distinct suction power modes, which you can choose on its companion app: the default 'Standard' mode, 'Turbo', intended for more stubborn debris, and 'Max', which is for vacuuming high-pile carpeting. Like many other eufy robot vacuums, it has a 'Boost IQ' function that lets it automatically increase its suction power when it's on carpets. However, this feature doesn't work as effectively on this vacuum as on similar models like the eufy RoboVac G20. There's a dedicated 'Spot Cleaning' mode that forces the vacuum to intensely clean a small, localized area. It comes with a remote control that allows you to make various commands without using its companion app.

There are few included attachments. The vacuum uses two side brushes to direct debris from its edges into the path of its main brushroll. Two spare side brushes are included. There's also a small hook blade cleaning tool to help remove stuck-on debris from inside the vacuum.

This vacuum performs superbly on bare floors. It easily deals with small debris like rice and bulkier material like cereal.

Debris pickup on low-pile carpet is disappointing. This vacuum doesn't suck up much in the way of larger debris like sand and has a very hard time dealing with finer material like baking soda, even with its 'BoostIQ' function enabled. Check out the eufy RoboVac 30C if you want a similarly-designed robot vacuum with a slightly more potent suction motor.

Debris pickup performance on high-pile carpet is okay. The eufy is decently effective in cleaning larger debris like sand but does a mediocre job of handling finer material like baking soda.

This vacuum does an alright job of handling pet hair on various floor types. It clears most pet hair on bare surfaces like vinyl or hardwood, but it might take an extra pass or two to get all of it on low and high-pile carpet. Like the eufy RoboVac G20, pet hair tends to get stuck in its brushroll rather than being sucked into its dirt compartment.

Real-world suction performance isn't very strong, especially compared to most conventional manually-operated vacuums. Its suction inlet is positioned too high above the contact surface to generate a tight seal on bare surfaces, resulting in low real-world suction power measurements. However, it still exerts a greater suction force than other robot vacuums in this price bracket. The standard variant has an advertised suction output of 1500Pa, though the top-trim 25C Max variant has an advertised 2000Pa of suction. However, this power difference isn't likely to be very noticeable in day-to-day use.

Although the Eufy RoboVac 25C has poor airflow performance relative to traditional vacuums, it performs decently for a robot vacuum. It's powerful enough to lift most debris but may struggle with larger or heavier debris.

The eufy 25C is very quiet. You'll hear nearby conversations even with the vacuum running in its 'Max' mode.

The eufy 25C does a mediocre job of maneuvering itself. Unlike the eufy RoboVac G20, it uses random pathing to navigate a space, meaning it moves in less organized diagonal sweeping patterns. That said, it's thorough when cleaning around chair and table legs. Unfortunately, it gets stuck on obstructions like rug tassels, power cords, and coat racks. It also has trouble climbing onto high-pile rugs.

This vacuum has bad air filtration performance. It isn't rated as allergen-sealed and doesn't have a HEPA filter, so fine particles can escape from its dustbin while cleaning.

Due to its low suction force, the eufy 25C does a poor job of sucking up debris from cracks and crevices compared to most manually-operated vacuums. It still outperforms alternatives like the Shark IQ Robot in this regard thanks in part to its twin side brushes, which can dig into crevices and drag debris toward the brushroll.

The eufy 25C doesn't have a mopping attachment and consequently has no impact on dried-on stains.

The eufy 25C has a reasonably wide range of physical automation features. The remote control that comes with the vacuum lets you use it without an internet connection. The remote's supported functions are listed below:

• "Charge": Return to its charging station
• "Suction Power": Change suction power level
• "Auto Clean": Start a random cleaning job
• "Edge Clean": Clean the outermost edges of a room
• "Spot Clean": Increase suction power to 'Max' and clean a small area in a spiraling sweep
• "Quick Clean": Clean for 30 mins and return to charging station
• Arrow buttons allow you to manually control the direction of the robot while it's cleaning
• Stop/Clean button

Unfortunately, unlike the eufy RoboVac 30C, it isn't compatible with physical boundary strips that you can use to prevent it from entering certain spaces.

The EufyHome companion app is decent. It lets you make the same range of commands as the physical remote controller but also schedule cleaning sessions. Since this vacuum doesn't map out its coverage area, there are no generated maps to set up virtual boundary lines or schedule room cleaning sessions. The vacuum responds to inputs made within the companion app with only minimal lag.
