Overview
The Eufy Omni E35 stands out as a highly effective robot vacuum cleaner and mop. Positioned within Eufy's product line, it offers an impressive 35,000 Pa suction power and features a clever system to prevent fine dust from clogging its filter, ensuring consistent performance.
Its charging dock provides truly hands-off cleaning by automatically emptying the dust bin, refilling the mopping water tank, and then washing and drying the mop with hot water and warm air. The navigation capabilities are robust, the Eufy app functions exceptionally well, and the overall cleaning performance of the E35 justifies its premium price.
While the E35 omits features like a fragrance diffuser, water ozonator, and the more advanced AI-powered navigation found in the pricier Omni S2, these omissions allow Eufy to focus on essential functionalities: effective floor cleaning and crucial self-maintenance.
The self-cleaning aspect is particularly impressive, with the mop remaining in pristine condition after weeks of use, the roller free from tangled hair, and the dust bin filter largely clear. This, combined with strong suction and a pivoting mop that reaches edges and scrubs stains while self-cleaning, makes the E35 a truly set-it-and-forget-it robot vacuum.
The Omni E35 serves as the new flagship model within Eufy’s E series of robotic vacuum cleaners, positioned above the E25 and E38, but below the company’s high-end S tier, which includes the Omni S2.
Notably, the E35 boasts slightly more suction power than the top-of-the-range S2 and incorporates much of the same self-cleaning and anti-tangle technology. The price difference is largely attributed to the E35's lack of the S2’s fragrance system, water electrolysis function, and more advanced vision system, which also contributes to the newer model’s more compact base station.
Design
The Omni E35 continues Eufy’s commitment to making its robotic vacuums more compact while simultaneously boosting performance. While the robot itself shares a similar form factor with other Omni family members, the docking station exhibits a significant reduction in bulk.
The E35 dock is designed to be shorter and sleeker, featuring a glossy plastic front, subtle silver trim, and integrated handles for easy removal of the clean and dirty water tanks. Measuring approximately 16 inches (around 40cm) tall and equally deep with the robot parked, the entire system is notably compact, which might lead one to mistakenly believe it's an entry-level device.
Within this compact dock, there is a charger, a dust bag, two tanks for clean and dirty water, and a system that washes the mop with 60C (140F) hot water before drying it with 55C (131F) warm air. A compartment is also available for Eufy’s floor detergent (one bottle included). Eufy states the system can operate entirely hands-free for up to 60 days, depending on home size and cleaning frequency.
The robot itself measures 4.6 inches (116mm) tall and 14.2 inches (360mm) in diameter, making it slightly larger than the Eufy S2 and marginally taller than the Dyson Spot+Scrub AI. Users should verify its dimensions against their furniture to ensure it fits underneath.
Eufy specifies a maximum threshold clearance of 1.2 inches (30.5mm). The source reviewer reported no issues with the robot transitioning from wooden floors to carpeting.
A smart design feature separates fine dust, directing it into the robot’s onboard bin before it reaches the filter. Eufy claims this helps the E35 maintain its 35,000 Pa suction power for longer by preventing rapid filter clogging. After testing, the source reviewer noted some dust accumulation in the filter, but it was easily cleaned and did not appear to impact performance. The device also includes an anti-tangle comb to keep hair from wrapping around the roller brush.
Performance
Eufy’s E series of robotic vacuums has consistently performed well, setting high expectations for the E35. The setup process is straightforward for anyone familiar with robot vacuum cleaners.
Assembly takes only a few minutes, followed by filling the clean water tank, installing the included detergent bottle, powering it on, and following the instructions in the Eufy app. The E35 then conducts a mapping expedition, quickly mapping rooms, walls, and doorways using its vision system.
Unlike the pricier Omni S2, furniture is not automatically added to the map. The source reviewer preferred this, as it leaves the floor plan unobscured.
As with many robotic vacuums, the source reviewer had to manually adjust the E35’s map, repositioning some walls and naming rooms. This is considered part of the setup process rather than a flaw in the vision system. However, the robot initially created a phantom room, which could not be deleted, necessitating a complete re-mapping. The second map was accurate and remained so throughout the testing period.
A key highlight of this robot is its maximum suction power of 35,000 Pa, which is 5,000 Pa more than the flagship Omni S2. This power delivers excellent results on both carpet and hard floors. For context, an older Eufy X10 Pro, which was highly rated two years prior, offered only 8,000 Pa.
The high suction power translates to impressive cleaning performance, particularly for vacuuming. Carpets were visibly cleaner after using Max mode. While this might be considered overkill for frequent light cleaning, the battery capacity allows for full carpet vacuuming in Max mode.
The source reviewer often used Max mode for the kitchen and living room, or switched to the middling Turbo mode for larger cleaning tasks to avoid mid-task charging. The robot also automatically increases suction when it detects carpets or rugs.
The Omni E35’s quietest mode, recorded at 60 decibels, was fast but left noticeable traces of fine debris. Turbo mode (64 decibels) with a more thorough clean also had similar results. However, using the ultra-powerful Max mode (67 decibels) with the Deep intensity option and two passes left carpets absolutely flawless, justifying the increased time and energy consumption.
The dust bin emptying process was recorded at 85 dB from approximately two feet away.
The robot performed surprisingly well in tests involving oats on hard floors, a task often challenging for robot vacuums due to side brushes flicking debris. Turbo mode, paired with Deep intensity and two passes, was sufficient to clear the debris completely, without needing Max power. Oats on carpet were handled even more successfully, with a single pass on the lowest power and least thorough setting proving effective.
The mopping function of the Omni E35 also impressed the source reviewer. It utilizes a system similar to Eufy’s flagship Omni S2, featuring a roller that self-cleans during operation and is washed and dried at the docking station. Eufy claims its HydroJet 2.0 system removes 99.99 percent of bacteria, certified by independent German testing organizations.
The 290 mm (11.4 inch) mop applies 1.6 kg (3.53 lb) of pressure, providing a thorough scrub rather than just a wipe. It is cleaned by a pair of scrapers eight times per second to prevent dirt accumulation. The roller can extend outwards by 32 mm (1.26 inches) to clean right up to walls, with dirty water collected in an onboard tank for later deposition at the charge station.
The effectiveness of the E35’s mop is evident from the visibly dirty water collected in the charge station tank. The source reviewer advises frequent emptying of this tank to avoid unpleasant odors.
Unlike the pricier S2, the E35 does not feature the ClearMind AI function, which intelligently recognizes floor types, stains, and messes to adjust cleaning. Instead, the E35 relies on user settings. The source reviewer found that a whole-room clean with middle or most powerful suction, about 75 percent water flow for mopping, the most intense cleaning pattern, and two passes generally yielded the best results.
While the S2’s AI system is sophisticated in adapting to messier areas, the cleaning outcomes on carpets and wooden floors were comparable between the two robots. The E35 also lacks the S2’s water ozonization feature, which is not considered a significant drawback.
The E35’s obstacle avoidance technology was tested by having it clean an area with a shoe, a sock, and a USB cable. The robot navigated perfectly, moving around each object without contact. Its ability to avoid the USB cable was particularly noted, as this can be a challenge even for high-end robot vacuums. Eufy states the robot can recognize over 280 common household objects and navigates effectively in both darkness and daylight.
However, the E35 is not entirely flawless in its navigation. It occasionally exhibited over-confident behavior, driving over obstacles that should have been avoided, such as a vinyl record stand that was about an inch off the ground, causing some records to be displaced.
App
The Omni E35 utilizes the standard Eufy app, which is also used for the company’s home security products. The app has matured significantly over recent years, offering a well-balanced amount of customization without being overwhelming.
Map creation and editing are effective, despite the initial phantom room issue encountered by the source reviewer. The app makes it easy to select specific parameters for each cleaning task. Users can also save custom cleaning routines (e.g., kitchen with intense mopping and two passes) as commonly used chores, which can then be added to the app’s home screen for one-tap activation.
A home screen widget can also be created to launch the E35 with a single tap.
Additional useful app settings include a child lock to prevent accidental activation and an off-peak charging feature, which can be programmed to align with cheaper overnight electricity rates.
One notable omission is a dedicated mop-only mode. The source reviewer found this frustrating, preferring the option for the robot to tackle dried-on hard floor stains with its mop first, ideally approaching in reverse to avoid transferring stains onto brushes before applying water and detergent.
Verdict
Eufy indicates this robot can operate hands-free for up to 60 days, after which users would primarily need to replenish water and potentially replace the dust bag, thanks to its effective self-cleaning system.
While Eufy’s Omni S2 is an excellent device, it is considerably more expensive than the E35. For users who do not require features like a fragrance diffuser or ozonated water, the E35 offers a significant cost saving without compromising core cleaning performance.
For homes with an even mix of hard floors and carpets, this robot is particularly well-suited, as it performs equally well on both surfaces.
Despite being more affordable than Eufy’s top-tier S2, the E35 remains a premium-priced robot vacuum. Budget-conscious consumers might consider more affordable models, though these would likely offer less powerful suction or a less comprehensive mopping and self-cleaning system.
Although the E35’s 1.2-inch threshold clearance is adequate, some models can navigate higher obstacles. Users with significant variations in floor height between rooms might need to explore other options.
