Roborock S7 vs Ecovacs N8 Pro Comparison Review

The Roborock S7 is a round-shaped robot vacuum with a low-profile design allowing it to go under most furniture and other households. It has a 14-inch diameter and stands at 4-inches.

As for the weight, it is 8 lbs. The Roborock S7 might not score highly in a low-profile test, but it’s appealing aesthetically.

It’s available in black or white, with a single power button and a raised turret at the top interface.

The Roborock S7 is a 2-in-1 robot vacuum. This means it can vacuum and mop simultaneously, so you won’t need to spend more on a separate robot mop. It offers wet mopping, courtesy of an onboard water tank. With ultrasonic sound, it detects the carpet, raises the mopping pad and increases the suction power for deep carpet cleaning.

You also can schedule only vacuuming routes. When it comes to specialization, the S7 is suitable for all types of bare floors, from hardwood and tile to linoleum and marble, among others. You can also rely on it to vacuum low, medium, and high pile carpets and area rugs.

Last, the S7 has been designed for homes with pets. It picks up all kinds of pet hair, from short to long dog hair and kitty litter. You can also trust it to wipe the wet paw marks and urine stains.

The Roborock S7 is an effective vacuum cleaner with a powerful brushless 4-speed motor that ensures 2,500 Pa (Max mode) HyperForce suction for deep carpet cleaning.

The other three modes are Quiet (600 Pa), Balanced (900 Pa), and Turbo (1500 Pa).

However, the S7 might not be the quietest model we have tested when it comes to operation noise. Quiet mode produces about 64 dB, while in Max+, the operation noise is around 72 dB.

The Roborock S7 is a robot vacuum with a mopping function. It features an S7’s VibraRise Technology for sonic mopping pad vibration at a rate of 3000 times per minute at a mop 600 g pressure. It has a 0.3 L electronic water tank, a peristaltic pump and intelligent mop lifting. The tank capacity is enough to clean up to 2150 sq ft of hard floor in one cleaning cycle.

There are three mopping intensities with different water flow: mild (150 min / 1650 times per minute), moderate (120 min runtime / 2300 times per minute), and intense (80 min runtime/ 3000 times per minute).

It also has a special fine mopping mode with double mopping and moving Z-shape pattern. To prevent the robot vacuum from wetting the carpets, Roborock designed the S7 with a carpet ultrasonic sensor located on the bottom.

The Robotock S7 might not have a real-time camera but navigates accurately courtesy of a laser-based LiDAR Navigation and Roborock’s updated Adaptive Route Algorithms that relies on sensors for obstacles and collision avoidance choosing the optimized routes for cleaning.

A retractable bumper in front also absorbs physical impact in the unlikely event the robot hits obstacles; the vertical bumper (a raised turret) in the middle protects the top. There are also 4 IR cliff sensors on the bottom to prevent falling.

In addition, the robot is equipped with a certified laser distance sensor (LDS) to reduce speed in front of obstacles.

The Roborock S7 is a state-of-the-art robot vacuum that creates and stores hyper-accurate digital maps of your home for up to four floors.

The S7 smartphone application also features digital boundaries (up to 10 no-go zones,10 no mop zones, and 10 virtual walls) that help you create custom boundaries where you don’t want the robot to reach.

With ultrasonic carpet recognition, carpets will be automatically marked on each floor map; also, the mopping pad automatically rises on carpets on 5 mm to prevent them from being wet.

In addition, the robot has adaptive route algorithms and automatic room recognition based on the type of surfaces; if required for each room, a customized cleaning can be set with a specific schedule.

The Roborock S7 comes with a washable E11 dust filter in a separate filter cover and a water filter in a water tank. The dust goes through the dust filter from the bottom to reduce its blockage and increase efficiency. It should be cleaned at least every 2 weeks and dried 24 hours before new use, and replaced at least after one year of usage.

The Roborock S7 comes with two brush systems. First is the main rubber brush with spiral fins to avoid better hair tangles and longer service life. Option of multi-directional floating provides better cleaning of uneven surfaces.

The brush is perfect for homes with pets and leaves no scratches on the floor. The main spiral brush is complemented by a side brush that reaches the deep corners and wall edge.

The Roborock S7 comes with a 0.47 L onboard dustbin that’s enough to hold quite a lot of dirt. Unfortunately, the S7 doesn’t include Roborock’s revolutionary Auto Empty Station with a 3L Dust Bag that can empty the robot vacuum for 60 days.

But the good news is that it’s compatible with the automated emptying technology, so you are all good if you upgrade it by purchasing the Auto Empty Station.

The S7 is a smart home-ready robot vacuum courtesy of 2.4GHz WiFi compatibility. The robot can be operated remotely using the Roborock App available, for both iOS and Android platforms.

Besides smartphone app operation, the S7 can sync with voice assistants, including Alexa and Google Assistant. Also worth mentioning is programmability. Homeowners can set their preferred vacuuming and mopping schedules, no-go zones, and digital walls, set section level, mopping pod vibration strength, and water flow.

The robot vacuum will leave its dock to clean your home when a scheduled time reaches. You can track via the application the cleaning progress and check the routes.

The Roborock S7 comes with a powerful 5,200mAh lithium-ion battery that can put up 180 minutes of runtime in Quiet mode.

However, on higher power modes, the runtime dips.

When it comes to power management, the S7 will dock to recharge when the power is low and resume cleaning afterward.

Lift the robot vacuum and check for tangles and signs of wearing on the bristles or fins. Remove the tangled hair and any other dirt. If there are signs of wear and tear, or the brush has served you for 8-12 months, buy a replacement.

At least twice a month, pop out the filter and tap it in a trash can to remove excess dirt. Then, rinse the filter using cold water, let it dry and return it. Replace filters after 6-12 months.

To prevent the buildup of bad odor, empty the S7’s onboard bin manually after each cleaning session. For the model with the Automatic Empty Station, remove the disposable bag when it’s full and insert a new one (about 60 days).

After a week of daily mopping, consider washing the mopping pads and leaving them to dry in readiness for subsequent use. The pads should be replaced when they show signs of wear and tear, probably after a month of daily mopping.
