Roborock S7 vs Deebot T8

Roborock S7 vs. Deebot T8 Face to Face Comparison Review

To help readers make the perfect decision, we have compared the two robot vacuums based on the critical aspects considered when buying a robot vacuum. Without further ado, here's how they square it out.
1. Design, Dimensions, and Weight
round-shaped

Roborock S7, just like its predecessors, is round-shaped and boasts a low-profile design that allows it to go under low-profile furniture and between tight spaces. It measures 13.9 × 353 × 3.8-inches and weighed 7.9lbs on our kitchen scale.

Available in two colors, black and white, the S7 is also similar to the previous models as it is glossy and comes with a raised turret at the top interface, alongside three control buttons.

round-shaped

The Deebot T8 is also a round-shaped robot vacuum with a small footprint to allow it to creep under low-profile house fittings and pass between tight spaces unrestricted. Its dimensions are 13.9 x 13.9 x 3.7 inches, while the weight is just 7.8 pounds.

The available colors are black and gray, with the former as the most popular variant in the US market. The T8 also has a raised turret and a control panel with a single button.

It's hard to call a winner here as both models are round-shaped and have a low profile design. The difference in dimensions and weight is negligible.

2. Cleaning Orientation
2-in-1

The Roborock S7 is a top-of-the-range robot vacuum that offers 2-in-1 cleaning. It can vacuum and mop simultaneously. When it comes to specialty, this robot vacuum is an all-rounder. You can rely on it to vacuum bare floors, including hardwood, tile, linoleum, marble, vinyl, and terrazzo.

The S7 is also ideal for homes with carpeted areas and area rugs. This robot vacuum will also come in handy for those with pets as it can pick up all kinds of pet messes, from pet hair and kitty litter to urine stains and wet paw marks.

2-in-1

Just like the S7, the Deebot T8 is also a versatile cleaner that can vacuum and mop simultaneously. You don’t need to buy a separate robot mop. Regarding its specialty, the T8 also offers exceptional cleaning on all bare floors, including tile, hardwood, marble, vinyl, ceramic, and the rest.

But the problem is with carpets. Its average suction power means it can only do well on low to medium pile carpets. As for high pile carpets and area argus, it gets overwhelmed. But when it comes to pet messes, the T8’s performance is satisfactory.

In this second round, Roborock takes an early lead. It is the best choice here as it can handle all types of carpets, something the T8 can’t.

3. Suction Power
2500pa

Roborock S7 comes with a next-gen variable speed motor that delivers a whopping 2500pa when in full power. For the record, there are four speeds – Quiet, Balanced, Turbo or Max.

As you may be aware, the higher the suction, the higher the operation noise. Luckily, the S7 has been tuned to offer quiet operation. Max mode is the loudest at 75dB, while in Quiet mode, the operation noise averages 65dB.

1500pa

Deebot T8, despite being one of the latest models from ECOVACS, puts up average suction. The robot vacuum has been engineered with a modern multi-speed motor that delivers 1500pa when firing on all cylinders.

There are three power modes – Standard, Max, and Max+. Regarding operation noise, the T8 is loudest when in Max+ at 72dB, while in Standard mode, it produces an average of 61dB.

Even though the Roborock S7 is louder, it's the winner here. This is because it has higher suction, and as you may be aware, raw power is critical in any vacuum.

4. Mopping
300ml water tank

The Roborock S7 takes mopping a notch higher courtesy of Sonic Mopping, a technology that scrubs floors up to 3000 times per minute, eliminating all stuck-on dirt, grime, and stains. The main components include a 300ml electric water tank optimized for efficient water usage. Water flow can be adjusted from the app. It’s also possible to customize water flow depending on the room you are mopping.

Another interesting feature is Ultrasonic Carpet Detection, which prevents the robot from wetting carpets. The system detects carpets and raises the mopping head courtesy of VibraRise. There is also No Mop Zones.

240ml water tank

The Deebot T8 is also a great robot vacuum with excellent mopping features. Mopping is based on ECOVACS’ revolutionary OZMO Mopping Technology. It constitutes a 240ml electric water tank with adjustable water flow and a microfiber for scrubbing.

This robot is also compatible with the OZMO Pro Oscillating Mop that offers better mopping performance. This is courtesy of the electronic mop that vibrates up to 480 times per minute, offering a deep clean. The T8 also tags along with Carpet Detection, enabling the robot to avoid carpets.

Here, The Roborock S7 is the winner, courtesy of the revolutionary Sonic Mopping Technology. But still, Deebot is a worthy choice if it is equipped with the OZMO Pro Oscillating Mop that offers the same level of mopping performance as Sonic Mopping. But considering this kit is bought separately, Roborock is the best value for money.

5. Navigation
LiDAR Navigation

The Roborock S7 is an intelligent robot vacuum that uses a SLAM-based algorithm for navigation. Dubbed PreciSense™ LiDAR Navigation, it uses sensors for localization.

There is also a set of obstacle detection and drop detection sensors that prevent accidents. If the robot hits an object, the retractable bumper absorbs the impact, thus preventing damage.

SLAM-based

Deebot T8, on the other hand, is also powered by a SLAM-based algorithm for navigation. Known as TrueDetect 3D Advanced Technology, the robot leverages sensors for obstacle avoidance.

There are also drop sensors that prevent falls.

As far as navigation is concerned, there is no clear winner between these two robot vacuums. None of them has a real-time camera. They avoid the common obstacles with high accuracy.

6. Mapping
Dubbed Precision Mapping

The Roborock S7 is an intelligent robot vacuum that relies on a 32-bit quad-core processor that complements LDS Laser Navigation in creating hyper-accurate maps of your home.

Dubbed Precision Mapping, the robot can create and store up to 4 maps, so the S7 is ideal for homes with multiple levels. Other features worth mentioning include No-Go Zones, No Mop Zones, Zone Cleanup, Selective Room Cleaning, Invisible Walls, and Real-Time Robot Location.

Multi-Floor Mapping

Deebot T8 is also an intelligent robot vacuum that knows your home the way you do. It relies on TrueMapping Technology, which leverages Advanced dToF Laser Navigation with Multi-Floor Mapping to create and store hyperaccurate maps of your home.

Here, you can create and store 2 fixed maps plus 1 new temporary map. TrueMapping offers 2X coverage and 4x accuracy than the previous technology, Smart Navigation 3.0. You can also send the robot to clean a specific spot and create boundaries right from the app.

Here, it's also hard to call a winner as both vacuums can create accurate maps and store them. However, the S7 sounds like the best deal now that it can store up to 4 maps and comes with several extras, for example, Real-Time Robot Location.

7. Filtration
true-HEPA filters

Roborock S7, despite being one of the latest models from this Chinese brand, doesn’t come with true-HEPA filters. Instead, it comes with washable E11 air filters that capture 95% of allergens that trigger allergies and bad odor.

3-layer dust filtration

The Deebot T8, just like Roborock S7, doesn’t include a true-HEPA filter. Instead, a 3-layer dust filtration that captures 99% of allergens, including pollen, dust, and dust mites as small as 0.6 microns.

While none of the two robot vacuums is ideal for homes with allergy sufferers, the Deebot T8 is the better choice. At least it can capture 99% of allergens. The S7 captures 95%.

8. Tools & Brushes
two brushes

The Roborock S7, just like all other Roborocks, comes with two brushes. There is the primary brushroll responsible for agitation and dirt pick up and the side sweeping brush for the wall edges and deep corners.

The Roborock all-rubber primary brushroll picks up all kinds of debris. However, it tends to get tangled when picking up the long dog hairs. All the same, it’s up for the task.

two brushes

The T8 also comes with two brush systems. There is a side sweeping brush for the wall edges, corners, and other spots where the primary brushroll can’t access.

The primary brushroll is a bristled spiral brush that picks up all debris. But just like the S7, this one too tends to get tangled quite often when picking up long dog hair., But for short pet hair, its performance is satisfactory.

It's hard to call a winner here as both models have the same brush features. But from our cleaning tests, Roborock's primary brush performed better.

9. Bin System
0.48L

The Roborock S7 comes with a 0.48L bin. It doesn’t come with the Auto-Empty Dock, so it can not empty itself automatically. But it is compatible with the technology, so if you buy the empty station, you are good to go.

On the other hand, the S7+ comes with the Auto-Empty Dock.

0.42L

The Deebot T8, on the other hand, comes with a 0.42L dustbin. It is also compatible with automatic self-emptying. But just like the Roborock S7, the T8 doesn’t include the emptying station, so you will have to purchase it separately or go for the Deebot T8+ as it comes with the emptying station.

Both the S7 and Deebot T8 are automatic self-emptying robot vacuums. But considering they don't come with the emptying station, you'd rather go for the Roborock S7 as it has a larger onboard bin.

10. Automation and Smart Features
2.4Ghz WiFi

Roborock S7 is an intelligent robot vacuum that can be scheduled to clean automatically for seven days straight. Interestingly, it can sync with smart home devices courtesy of 2.4Ghz WiFi compatibility. The most practical smart features include remote mobile app operation.

You can control the robot vacuum from the office on the Roborock Home App. What’s more? The S7 can sync with voice assistants such as Alexa and Google Assistant.

2.4Ghz WiFi

Just like the Roborock S7, the Deebot T8 can also be scheduled to clean for an entire week. So you can focus on other chores. This robot vacuum too features 2.4GHz WiFi for smartphone operation via the ECOVACS Home App.

On the app, users can remotely start cleaning sessions, set cleaning schedules, view reports, etc. Besides smartphone operation, the T8 can sync with Alexa and Google Assistant.

As far as automation and smart features are concerned, this is a draw. The two robot vacuums can be scheduled and are smart home ready.

11. Battery and Runtime
5200mAh/180 minutes

Like all other Roborock models, the S7 features a large 5200mAh lithium-ion battery that offers a cool 180 minutes runtime in Quiet mode.

The robot can also recharge and resume cleaning automatically and has a quick charge feature dubbed Top-Up Charging. It recharges just enough juice to complete the cleaning instead of waiting for the entire 3 hours recharge time.

5200mAh/180 minutes

Deebot T8 and Roborock S7 are akin in terms of battery performance. Here again, a 5200mAh battery that offers 180 minutes runtime has been used. The T8 also has auto-recharge and auto-resume capabilities.

The only difference is the slightly longer runtime and the fact that the T8 doesn’t have a quick charge function.

Both the S7 and T8 offer the same runtime and power management features. However, the S7 is the best choice as it comes with Top Up Charging, and the recharge time is slightly shorter.
