Based on a review by Vacuum Wars (accessed 2026-06-19).
Based on this review alone: buy it if you care about powerful vacuum suction and airflow scores significantly above average — just accept below average navigation efficiency and floor coverage per minute due to embedded lidar.
The reviewer concludes that the T80S is an economical choice offering solid floor cleaning, great obstacle avoidance, and effective dock automations, with minimal trade-offs compared to more expensive models like the T90. It earned a spot on their top 20 robot vacuum list, especially for those prioritizing value.
This review provides an in-depth analysis of the Ecovacs Deebot T80S Omni robot vacuum, which the reviewers purchased for testing. It covers the robot's performance in vacuuming, mopping, obstacle avoidance, threshold climbing, base station functionality, battery efficiency, and app features. The review also highlights some cons, primarily related to navigation efficiency.
The Ecovacs Deebot T80S Omni is an excellent value robot vacuum, delivering premium features and strong cleaning performance at a mid-range price point. It achieved an impressive 91% sand removal in carpet deep clean tests and flawlessly removed 100% of pet hair without tangling its Zero Tangle 3.0 brush system. While its embedded LiDAR navigation resulted in below-average floor coverage per minute, its superior battery efficiency helped compensate for the slower routing. If you are seeking a powerful all-around floor cleaner with exceptional obstacle avoidance and comprehensive base station automations, this model is a great economical choice. However, if your home has particularly tall or complex thresholds, you might consider the T90 for its superior climbing limit.

measurement_testpositivet=0:47–0:58
In bench tests, the T80S had a strong suction score that was two and a half times the average and its airflow bench test was notably higher than the average.
measurement_testpositivet=0:58–1:15
In the carpet deep clean test, where sand is embedded into medium pile carpet, the T80S pulled out 91% of the sand, which is way above average and even surpassed the T90 score.
measurement_testpositivet=1:28–1:44
The T80S removed 100% of 2.5-inch flattened hair from carpet in pet hair pickup tests and showed zero hairs tangled around either brush in the tangle test with 7-inch hairs.
hands_on_demopositivet=2:20–2:35
The roller mop lifts 6 inches (15 mm) over carpets to prevent wetting the fibers, allowing the robot to clean both hard floors and carpets in a single run.
measurement_testpositivet=2:45–2:59
The T80S scored very well in the dried-on stain test, comfortably above average, and had a great water penalty score, leaving very little water behind.
measurement_testpositivet=3:20–3:35
The T80S achieved a much higher than average score in standard and torture tests for obstacle avoidance, avoiding 21 out of 24 possible objects.
measurement_testpositivet=3:39–3:58
The T80S had no problems crossing 19 mm thresholds in tests, although the premium T90 can handle higher thresholds (up to 32 mm in test).
hands_on_demopositivet=4:00–4:24
The multi-functional base station washes mops in hot water (75°C/167°F) and dries them with hot air (62°C/145°F) to prevent grime and odors.
hands_on_demopositivet=4:24–4:34
The base station empties debris into a sealed bag, refills the robot's freshwater tank, and empties its dirty water tank.
measurement_testpositivet=4:35–4:49
The T80S has a higher than average official battery life of 205 minutes and covered more square meters per 1% of battery life than the average robot in tests.
reviewer_claimpositivet=4:50–5:17
The Ecovacs app is full-featured, offering no-go and no-mop zones, room customization, scheduling, and fine-tuned cleaning settings like mopping along the floor direction to minimize streaks.
measurement_testnegativet=5:18–5:42
Navigation efficiency was below average, resulting in less floor coverage per minute and slightly below average estimated total coverage per charge, likely due to its embedded LiDAR.
The T80S demonstrated a strong suction score, two and a half times the average, and excelled in removing debris from various surfaces. In the carpet deep clean test, it removed 91% of embedded sand, surpassing the average and even the T90 model. It is described as a powerful vacuum cleaner, performing well at its main job.
The T80S performed outstandingly in pet hair pickup tests, removing 100% of flattened hair from carpet. Its Zero Tangle 3.0 brush system, featuring bristles and a comb, also prevented any hairs from tangling around both the main and side brushes in a dedicated tangle test.
The T80S uses the Osmo 2.0 mop, which cleans itself and picks up wet messes without spreading them. It scored very well in dried-on stain tests and left minimal water behind. Crucially, the mop roller lifts 6 inches (15 mm) over carpets, allowing the robot to vacuum and mop in one go without wetting carpeted areas.
Utilizing an RGB camera with LED light assist and 3D structured light sensors, the T80S achieved a much higher than average score in obstacle avoidance tests, successfully avoiding 21 out of 24 possible objects. This performance is considered very high for any robot vacuum, especially in its mid-range price tier.
The base station offers comprehensive automation, washing the mops with hot water (75°C/167°F) to remove grime and drying them with hot air (62°C/145°F) to prevent odors. It also automatically empties the robot's debris into a sealed bag, refills its freshwater tank, and empties the dirty water tank.
The robot's navigation efficiency was identified as a weak point, resulting in below-average floor coverage per minute. This inefficiency, attributed to its embedded LiDAR system, means it might take longer to route around a floor plan and has an increased chance of getting lost. Some early customer reviews also cited mapping issues and weird movements, aligning with this observation.
100/100 source quality
Vacuum Wars reviews the Ecovacs Deebot T80S Omni, comparing it to premium models. The T80S demonstrates strong vacuuming performance, achieving high scores in deep carpet cleaning and perfect pet hair removal, thanks to its Zero Tangle 3.0 brush system. Its mopping capabilities are also impressive, utilizing the Osmo 2.0 system to clean dried stains and lift over carpets. Obstacle avoidance is a standout feature, with the robot avoiding 21 out of 24 objects. While battery efficiency and the multi-functional base station are pros, navigation efficiency is a drawback due to its embedded LiDAR.
