Cleaning Paths

An efficient cleaning path is the earmark of any great robotic vacuum, and the Roborock E35 has it nailed. When operating in vacuum mode, the robot moves in a Z-shaped pattern to cover the most floor in the least amount of time. When set to mop mode, the E35 stays in a straight line, suctioning as it mops to prevent dribbles.

Roborock E35 Robot Vacuum and Mop Review

Water Reservoir

On the undercarriage of the robot, there’s a 5.1-ounce removable reservoir. Ingeniously designed, the reservoir only releases water onto the mop pad when the robot is in motion, leaving no spots of water on the floor. If your home is plagued with hard water, don’t worry – The reservoir is equipped with two filters.

Dirt Bin

A door on the robot’s top panel reveals the easy-to-access dirt bin. With a capacity of 21.6 ounces, the bin can hold a lot of debris, reducing the frequency of garbage can trips. Inside the filter box, there’s an E11 high-efficiency filter, which does an excellent job of trapping dust and other allergens.

Roborock E35 Review

Brushes, Pads and Suction Speeds

Roborock thought of everything a robotic vacuum/mop would need to clean any kind of floor. The tangle-resistant V-shaped brushroll lifts stubborn dirt while the side brush sweeps wall edges.

The mop pads are reusable, and they stay secure on the plate at all times. There are five suction speeds and a spot-clean mode from which to choose. When vacuuming carpet, the robot increases the suction to 2,000 pascals.

“The Robotock E35 robot vacuum/mop offers a novel way to clean your home. Featuring one of the longest operation time for a single battery charge, the vacuum allows you to clean larger areas without interruption.”Vacuumsguide.com

An Amazing Two-in-One Robot

Overall, Roborock did an outstanding job when it engineered the E35. With the Roborock E35, you don’t need one robot to mop and another one to sweep.

It manages to do both without sacrificing mopping or vacuuming performance. We also love that it’s enabled with Wi-Fi and compatible with Alexa. Take a look at how the E35 compares to Roborock’s other robotic vacuum/mop combos.

Roborock E35 vs. S5 (S50 vs. S55 vs. S51)

While the Roborock E35 comes in a gray finish with black trim and the Roborock S5s are all white with varying trim colors, there are significant operational differences between the E35 and the S5 models. The E35’s dirt bin holds 21.6 ounces, making it 5.4 ounces bigger than the bin on the S50, S55 and S51. For you, this means a longer period between bin cleanings.

Roborock E35 vs. S50 vs. S55 vs. S51

Each one is equipped with a 5,200 mAh battery, which lets all the robots vacuum or mop and simultaneously suction for up to 150 minutes. When it’s time to recharge, they all drive to the dock and resume cleaning once their batteries are replenished. In addition to their six cleaning modes, these robots also raise their suction to 2,000 pascals when they detect carpet.

However, the Roborock S5 vacuum/bionic mop models boast a variable-speed side brush and a self-adjusting brushroll to clean wall edges and floors as thoroughly as possible. On the E35, the side sweeper and rolling brush are stationary.

The S5s also offer zoned cleaning, map saving and no-go zone customization on the Mi Home app; these features are absent on the E35. While both support Alexa, only the S5 robots are compatible with Google Assistant.

You’ll also notice differences in the way the E35 and the S5s navigate. The Roborock E35 uses inertial navigation, which consists of gyroscopes and motion sensors. On the other hand, the S5s rely on a laser-distance sensor and SLAM real-time mapping. Therefore, the Roborock S5 robot vacuums can cover over 200 square meters per charge, while the E35 can only clean 150 to 200 square meters.

Roborock E35 vs. Roborock E25

At first glance, you may think the E35 and the E25 are the same, but the Roborock E35 packs more power than the E25. With the E35, you get 2,000 pascals of strong suction when in max mode or automatic suction-boost mode. Although the Roborock E25 has the same carpet-detecting sensor that increases the suction, the E25’s suction tops out at 1,800 pascals.

Roborock E35 vs. Roborock E25

The other major difference between the two vacuum/mop models is the battery. For the E35, Roborock used a 5,200 mAh lithium-ion battery. Although the Roborock E25 also has a lithium-ion battery, its capacity is smaller at 2,600 mAh. Therefore, the E35 runs up to 50 minutes longer than the E25. Due to the stronger suction and larger battery, the E35 can clean an additional 50 square meters of floor per charge.

Despite a few tweaks, Roborock kept much of the same technology on the E35 that it used with the E25, including protective sensors and dual gyroscopes for logical route planning. Each robot is enabled with Wi-Fi, so you can set a schedule and monitor the robot’s status from the Mi Home app. You can even start, stop and dock the robots with Alexa. The E35 and E25 also automatically recharge and resume cleaning.

Since both suction while they mop and only release water when in motion, you don’t have to worry about water spots on the floor. Their large dirt bin loads from the top, and each one has a single side brush and angled brushroll. You also get a few convenient onboard controls, including spot mode. No matter the task at hand, one of the six cleaning modes can certainly handle it.

At the end of the day, the Roborock E35 is an affordable and powerful robot vacuum. It offers an excellent vacuuming system, which makes vacuuming on hard and soft floors very easy. Plus, it has a simple, yet effective, mopping system. By using this mopping system, you’re able to remove small stains and messes from your hard floors. For many people, though, the most convenient feature this robot vacuum offers is its 2.5-hour battery-life. With this battery-life, you can vacuum clean your entire home in just one vacuuming session.

Pros: Excellent vacuuming power, very useful mopping system, long battery-life

Cons: Mop isn’t useful for bigger stains, smart features aren’t particularly unique
