Roborock vs Ecovacs Reviews

Below are comparisons of popular models from Ecovacs and Roborock reviewed with quick and concise verdicts, and per your budget, lifestyle, needs, and home layout.

Deebot T9 vs. Roborock S7

ecovacs_deebot_t9_vacuuming_and_mopping_robot
Ecovacs Deebot T9
roborock_s7_smart_home_cleaner
Roborock S7

Feature-rich, advanced, and pricey. At more than $700, either of the Deebot t9 or Roborock s7 suffices if you’re big on convenience and efficiency. Also, if you plan to do a lot of mopping, have a large house, hard floors, and don’t mind the price.

Elsewhere, and while the Roborock s7 and Ecovacs t9 can avoid carpet in mopping mode, the s7 is the one to get if you have mixed floors (especially hardwoods or tiles on either side of a carpet) since its mopping plate lifts, as against the Deebot t9 that just avoid carpets altogether. Similarly, the Roborock s7 has better navigation (gentler and more precise) and app and receives regular software updates.

Get the Ecovacs t9 if you have mostly carpets giving its strong suction and airflow added to its ability to resist carpet fibers.

Also, consider the Deebot t9 if you have a cluttered setup with toddlers that can make a mess or pets prone to accidents, or if you have issues with odor. Additionally, Deebot is the quieter of the two although you can get a close experience by running the Roborock on low power.

Deebot T8 AIVI vs. Roborock S7

roborock_s7_smart_home_cleaner
Roborock S7
deebot_ozmo_t8_aivi_robot_vacuum_and-mop
Deebot Ozmo T8 AIVI

Advanced, pricey and feature-rich, the t8 aivi or s7 is ideal in a large, multi-level home with primarily hard flooring. Likewise if you plan on doing a lot of mopping.

The Deebot t8 aivi, assuming you’re wondering, is a cheaper Deebot t9 w/o the pro mop attachment (sold separately) and w/ an app and software that can use some improvements. Regardless, the Ozmo t8 AIVI robotic cleaner is the perfect choice in a multi-level house with extended carpeted areas and/or pets that shed or are prone to accidents.

Deebot N8
roborock_s7_smart_home_cleaner
Roborock S7

Advanced, pricey and feature-rich, the n8 or s7 is ideal in a large, multi-level home with primarily hard flooring.

The Deebot n8, just so you know, is a Deebot t8 AIVI with upgraded hardware and software. It, therefore, makes sense if you can’t find the t8 AIVI on sale or if you’d rather play safe with your money while potentially saving time on troubleshooting or going back and forth with support. Even better if you live in a busy house with pets and kids, have large carpeted areas, or if you plan on doing a lot of mopping.

Deebot Ozmo T8 AIVI
roborock_s6_maxv_hybrid-floor_cleaner
Roborock S6 MaxV

Advanced, feature-rich and at about the same price, either of the Roborock s6 MaxV or Ozmo t8 AIVI fits in a complex, busy, multi-level house with extended mopping areas. 

Per the t8 aivi’s increased suction and compatibility with the self-emptying tower, it’s the one to get if you have wall length carpets and pets that love to shed.

The Roborock s6 MaxV is a better choice in a multi-level house with mostly vinyl, tile or wood floors. You also can’t go wrong if navigation, reliability, and product and customer support are top priorities.

Deebot T8 AIVI vs Roborock S6

ecovacs_deebot_ozmo_t8_aivi_vacuuming_and_mopping_robot
Deebot Ozmo T8 AIVI
roborock_s6_vacuuming_and_mopping_robot
Roborock S6

Without the clean station and with basic mopping and carpet cleaning ability. Nonetheless, the Roborock s6 cleans intelligently, supports custom settings, and is more affordable. Add that to its laser vision and 55 decibels noise, the s6 is a better choice if noise and navigation are big factors.

The Ozmo t8 AIVI, on the other hand, has increased suction. The emptying tower and mop attachment are available as an add on. It’s therefore ideal if you have large carpeted areas, pets that shed or are prone to accidents, or if you’re planning on doing a lot of mopping. 

Deebot T8/AIVI vs Roborock S5 Max

Deebot Ozmo T8 AIVI
roborock_s5_max_vacuuming_and_mopping_robot
roborock s5 max

Starting with similarities, the t8/aivi and the Roborock S5 Max

  • Vacuums and mops;
  • Quickly and accurately maps and saves floor plans (two in the Deebot vs. four in the Roborock);
  • Automatically recharges and resumes;
  • Have carpet detection (in vacuuming mode) and avoidance (in mopping mode);
  • Have advanced settings and controls, including keep-out zones, room cleaning, zone cleaning, and room-specific scheduling; and 
  • Intelligently vacuum hard floors, carpets, animal litter, human hair, dust bunnies, etc. 

In addition to the laser vision which both models use for pathing and mapping, the t8 family of the Deebot has a front camera (AIVI version) and a 3D sensor (regular version) for real-time avoidance of common obstacles like socks, kids’ toys, stray cord, and slippers. Also, with the T8 there’s an option to add a self-emptying base and vibrating mopping module. 

As for the vibrating head of the T8, in a few tests I have seen, there isn’t much of a difference compared to the onboard mop attachment:

Talking about the consistency of operations and usability, there’s no arguing the Roborock s5 max’s ability and reliability. Where things get really interesting is the somewhat night and day difference in the performance of the t8 (regular version) and the t8 AIVI even though the two are essentially the same unit, with the only difference being the technology they use for object avoidance (3D sensor in the regular version vs. artificial intelligence in the AIVI version). 

The app of the t8 robovac, while it may occasionally lag or clunk still manages to give a solid, hands-free performance. The app of the t8 AIVI is no better either in this aspect except there’s more. 

Deebot Ozmo t8 AIVI smart vac has trouble with mapping, as such it keeps creating or forcing users to create new maps time after time after time. As a result of its mapping inadequacies, the T8 AIVI bot may struggle to dock correctly while ignoring settings and controls. 

Talking of the AIVI tech, most demonstration of this feature that I have seen–and that you’d likely see–used a fake poo. But then two reviewers on Amazon, supporting their claims with images, noted the object avoidance feature failed poo test in their homes.

Tl;dr: Get one of the Deebot T8 or Roborock S5 max if you have mostly hard floors and live in a large and/or multi-level home. 

The T8 smart automatic cleaner (note: the regular version with the grey appearance and NOT the AIVI one) makes perfect sense if you have mostly carpets in a complex environment with kids, pets, and lots of objects on the ground.

Deebot Ozmo T5 vs Roborock S5 Max

roborock_s5_max_vacuuming_and_mopping_robot
Roborock S5 Max
ecovacs_deebot_ozmo_t5_vacuuming_and_mopping_robot
Deebot Ozmo T5

So the Deebot Ozmo t5 is an advanced model with custom cleaning options, logical pathing, and the ability to recharge and resume cleaning missions while vacuuming and mopping. It has a huge range and battery life (can cover up to 3200 sqft on a single charge). Further, the bristle brush can be engaged for hard floors and rugs, or the brushless one for pet hair vacuuming. And of course, the Deebot t5 supports floor mapping, allowing up to three-floor maps for saving.

There’s a possibility the floor mapping function on the Deebot t5 might be unusable/ineffective, though, resulting in spontaneous behaviors with rooms getting skipped, the bot insisting on cleaning certain spots, or being unable to traverse over doorways that are even less than the 20mm height limit it’s advertised with. On top of that, the app offers limited instructions/help.

Thankfully the Roborock s5 max offers an improved package. Besides being multi-functional like the Deebot t5–plus offering advanced controls and settings (no-go zone, no-mop zone, selective room cleaning, room-specific mopping, etc.)– it has major upgrades in navigation and mapping.

Maps don’t disappear, for one. Roborock s5 Max can cross barriers up to 20mm in height and does this quite reliably. It paths in straight efficient lines which helps to reduce jamming problems while improving reach and coverage. Further, Roborock releases timely software updates, has a more responsive app, and helpful customer support.

Given its superior cleaning ability, navigation, mapping, and stable operation, clearly, the Roborock s5 Max is a better choice. It’s ideal if you: 

  • Live in a big and/or multi-level house
  • Have hard floors or carpets (low- through medium-pile) with fewer obstacles
  • Have pets or people with short hair
  • Want a robot that cleans in neat rows and is less hands-on. 

Deebot Ozmo 950 vs Roborock S6 MaxV

Deebot Ozmo 950
roborock_s6_maxv_vacuuming_and_mopping_robot
Roborock S6 MaxV

Talking about the Deebot Ozmo 950 vs. Roborock S6 MaxV both

  • Can vacuum and mop;
  • Have advanced settings and controls, including but not limited to keep out zones, room cleaning, and zone cleaning; 
  • Intelligently vacuum hard floors, carpets, animal litter, human hair, dust bunnies, etc.;
  • Map the house and save floor plans (three in the Deebot and four in the Roborock); and
  • Automatically recharge and resume cleaning missions.

The mopping result is about the same. The Roborock s6 MaxV has a bigger, electronically controlled water tank. It also supports selective room cleaning

S6 MaxV is precise and gentle in its movement. It tangles less (thanks to the advanced object recognition and avoidance technology), doesn’t knock off items on the floor, and is better at getting out of difficult situations. Further, the s6 MaxV maps quickly and accurately. Mapped floors are available when needed, stable, and are easy to manipulate. 

There have been durability issues associated with the Ozmo 950. Some users have mentioned their devices started acting up as early as five months into the purchase. The Roborock s6 MaxV is a new release (released mid-2020) so really no comparison there. Besides its carpet deep cleaning ability, the Ozmo 950 robot vacuum is also better priced.

The Roborock s6 MaxV on the other hand is more user-friendly, with impressive threshold climbing and hard floor cleaning abilities. 

Being the ultimate winner, get the Roborock s6 MaxV vacuuming and mopping robot if you:

  • Plan to do a lot of mopping
  • Live in a big and/or multi-level house
  • Have hard floors (tile, stone, marble, laminate, wood, etc.)
  • Have pets or people with short hair
  • Want a robot that cleans in neat rows and is less hands-on
  • Have a complex layout with kids and lots of objects on the ground.

Similar to the Deebot Ozmo 950 vs. S6 MaxV scenario–while smart, feature-rich, advanced in settings and controls, with impressive cleaning abilities–usability remains a drawback on the Deebot 950. The Roborock s6 robotic vacuum cleaner wins here in that it consistently clean in a back and forth pattern without aggressively bumping into objects or missing/skipping spots or rooms. Similarly, the s6 is better at negotiating obstacles and traversing thresholds.

Further, the S6 maps floor quickly and accurately without losing connection while also offering an overall better app experience. 

Watch this video from Vacuum Wars highlighting the similarities and differences between the Deebot 950, Roborock s6, and Roomba i7:

Being the obvious winner, get the Roborock S6 vacuuming and mopping robot if you:

  • Live in a big (~2000sqft) and/or multi-level house with fewer obstacles;
  • Have mostly hard floors (wood, tile, stone, laminate) or a mix of hard floors and carpets (low and medium pile);
  • Have pets or people with short hair;
  • Want a robot that cleans in neat rows and is less hands-on;
  • Want a very quiet machine that supports nondisruptive conversations or sleep;
  • Want to clean at night without having the lights on;
  • Are allergic or a clean freak.

With the mopping function being the major upgrade in the S5 max over the S6. Meaning much of the information that applies in the Ozmo 950 vs. Roborock S6 also applies here. Or, in other words, the Roborock S5 max robotic vacuum cleaner paths logically without aggressively bumping into objects or missing/skipping spots or rooms. Also, it’s better at negotiating obstacles and traversing thresholds. The Roborock S5 Max map floors quickly and accurately. It doesn’t lose connectivity, while also providing a seamless app experience.

roborock_s5_max_vacuuming_and_mopping_robot
Roborock S5 Max
deebot_ozmo_920_vacmop_floor_cleaner
Deebot Ozmo 920

Talking of the Deebot Ozmo 920 and the Roborock s5 max, both

  • Are smart–with speed-sensitive side brushes for proper cleaning along walls and to avoid scattering debris in open areas; plus, the ability to clean in a back and forth pattern while automatically recharging and resuming cleaning missions.
  • Are feature-rich–with the ability to map and save floor plans. Three in each case.
  • Are versatile–with the ability to reach difficult areas including under beds and sofas.
  • Have advanced controls and settings–with the ability to adjust water levels, select rooms for cleaning, or set keep-out zones.
  • Have a mop function.
  • Have Smart Home integration.

The Deebot 920 if it helps to mention actively detects carpets in mopping mode whereas the Roborock S5 Max requires creating no-mop zones in the app. Roborock runs longer though (at around 180 minutes on low power) compared to 110 minutes on the Deebot 920.

To put it simply, the Deebot 920 works quite well in all respects except reliability. Common issues include;

  • Ignoring scheduling and keep-out zone settings
  • Getting lost and not finding the home dock
  • Aggressively bumping into objects such as lamp cords and then getting stuck
  • The water tank refusing to drip water
  • Its tendency to the dreaded LDS sensor error which in most cases makes the robot unusable.

Thankfully the Roborock S5 max shines where the Deebot failed–consistent operations. For one, the Roborock S5 max keeps to scheduling routine (also supports room-level scheduling) and will not disregard commands by going into troubled zones/unwanted places. And because it’s intentional in its movement, the Roborock S5 max smart floor robot doesn’t get lost or confused nor mindlessly ram into objects leading to a decreased tendency of getting stuck and less babysitting. Not only that, the S5 Max vacuuming robot finds its dock every time.

What’s more, the mopping function of the S5 max is very well built allowing for intensive mopping. Not to mention its upgraded processor that minimizes errors while allowing for efficient and convenient cleaning

Being the ultimate winner, get the Roborock S5 Max vacuuming and mopping robot if you:

  • Plan to do a lot of mopping
  • Live in a big (~2000sqft) and/or multi-level house with fewer obstacles
  • Have mostly hard floors (wood, tile, stone, laminate) or a mix of hard floors and low and medium-pile carpets
  • Have pets or people with short hair

Deebot Ozmo 901
roborock_s4_robot_vacuum
Roborock S4

As far as the Deebot Ozmo 901 and the Roborock s4 is concerned, both

  • Are smart–with speed-sensitive side brushes for proper cleaning along walls and to avoid scattering debris in open areas; plus, the ability to clean in a back and forth pattern while automatically recharging and resuming cleaning missions.
  • Are feature-rich–with the ability to map and save floor plans. Three in each case.
  • Are versatile–with the ability to reach difficult areas including under beds and sofas.
  • Have advanced controls and settings with the ability to select rooms for cleaning or set keep-out zones.
  • Have Smart Home integration.

The Deebot 901 vacuums and mops whereas the Roborock s4 only vacuums. Roborock runs longer though (at around 180 minutes on low power) than 110 minutes working time on the Deebot 920.

To put it simply, the Deebot 920 works quite well in all respects except reliability. Top issues include 

  • Ignoring keep-out zone settings; 
  • Getting lost and not finding the home dock;
  • Aggressively bumping into objects such as lamp cords and then getting stuck; 
  • Losing floor maps; and
  • Its tendency to stop working after a couple of months.

Thankfully the Roborock s4 shines where the Deebot failed–consistent operations. For one, the Roborock s4 will not disregard commands by going into troubled zones/unwanted places. And because it’s intentional in its movement, the Roborock s4 smart floor robot doesn’t get lost, confused, or mindlessly ram into objects resulting in a decreased tendency of getting stuck and less babysitting. Not only that, the s4 vacuuming robot finds its dock every time.

What’s more, the Roborock s4 robot vacuum is very well built allowing for some years of meaningful useful life. Its upgraded processor and constantly updated software minimize errors while allowing for efficient and convenient cleaning

  • Want to clean at night without having the lights on
  • Are allergic or a clean freak

Conclusion

There goes a comparison of some of the best robot vacuums from Ecovacs and Roborock. Assuming you missed it, Deebots are solid performers on carpets whereas Roborock is the king of navigation.

Talking about the reviews, I went for brevity. In other words, only key highlights of the featured items were summarized. This is to allow for quick decision-making. When you choose a brand or product, you may then proceed into reading an in-depth version (links provided & videos attached) where benefits and limitations are discussed in greater detail. 

Ecovacs bots if it helps to mention have software issues that usually don’t get fixed instead a new model will launch. It was the case in the 900 series that got abandoned for the T5 series, and now the T5 has been abandoned for the T8 family which, like its predecessors, is also bedeviled with navigation, mapping, and app issues.

Roborock robot vacuums, it turns out, excel in hardware, software, performance, usability, pricing, product, and customer support. If you don’t have a lot of carpets or rugs, and while they aren’t perfect, they’re by far a better choice.
