Quick Answer: The Ecovacs Deebot T80S Omni currently ranks #8 overall (3.92) on Vacuum Wars’ live Top 20 as of October 2026, at $657.37 on Amazon. It posts a perfect 100% pet-hair pickup and 21/24 obstacle avoidance, both independently measured — but the same lab testing flags navigation efficiency as its clearest weakness, covering floor space slower than the category average. Its claimed 24,800 Pa suction measures at just 2.44 kPa on the bench, the same claimed-vs-measured gap seen across almost every model this site has reviewed. Verdict: a strong pet-hair pick that takes longer to finish the job.
The Deebot T80S Omni sits in an unusual spot: it outranks several pricier Ecovacs and Dreame models on Vacuum Wars’ live Top 20 leaderboard, yet it’s never had its own dedicated review on this site — despite being referenced in the lab’s own category-average comparisons used across our Deebot T90 Pro Omni coverage. This review covers what actually got measured: where it beats the category average, where it falls short, and why navigation speed is the number to watch before buying.
Ecovacs Deebot T80S Omni by the numbers
- 24,800 Pa — Ecovacs’ claimed suction figure (marketing/fan rating, not the lab’s sealed-suction bench measurement).
- 2.44 kPa / 19 CFM measured suction — Vacuum Wars’ bench test result, above the ~0.99 kPa / 17 CFM category average.
- 100% pet-hair pickup, 0% tangle — both perfect scores on the flattened pet-hair and 7-inch hair tests, matching the Deebot T90 Pro Omni.
- 91% deep-carpet cleaning — ahead of the ~78% category average.
- 21/24 obstacle avoidance — well above the 16/24 average, just short of the T90 Pro Omni’s 23/24.
- 0.62 sq m/min navigation efficiency — below the 0.71 average and the clearest weak point, per both Vacuum Wars and Cybershack’s independent reviews.
- $657.37 — current Amazon price (October 24, 2026); has ranged $509-$1,799 across regions and promo windows this year.
- #8 overall, 3.92 score — current rank on Vacuum Wars’ live Top 20 as of October 2026.

Pet hair and obstacle avoidance: genuine strengths
The clearest reason to consider the T80S Omni is pet-hair performance. Vacuum Wars’ bench testing recorded a perfect 100% pickup on the flattened pet-hair test and a perfect 0% tangle rate on the 7-inch hair test — matching the pricier Ecovacs Deebot T90 Pro Omni on both metrics, thanks to the same ZeroTangle brush philosophy (3.0 here, 4.0 on the T90). Obstacle avoidance is nearly as strong: 21 of 24 test objects successfully avoided using its RGB camera and structured-light sensor system, against a 16/24 category average.
Carpet cleaning holds up too, at 91% deep-carpet removal — ahead of the roughly 78% average — and its threshold crossing is a rare case where the claimed spec basically holds: Ecovacs rates it for 20mm and the lab measured it clearing 19mm, a far smaller gap than the claimed-vs-measured threshold stories common on this site’s other flagship reviews.
Where it falls short: navigation speed
The catch is cleaning speed. Vacuum Wars’ own bench test measured navigation efficiency at just 0.62 square meters per minute, below the 0.71 average and well behind the T90 Pro Omni’s 0.75 — meaning the T80S Omni takes noticeably longer to finish the same floor plan despite its strong per-pass numbers. Cybershack’s independent review flagged the same issue, also noting a noisy auto-empty cycle and some dust-retention complaints. Vacuum Wars attributes part of the slower routing to its embedded LiDAR design, which it says can make path-planning less efficient than rivals using a raised turret sensor.
Suction tells a similar “claim vs. reality” story seen across nearly every model this site has reviewed: Ecovacs’ own 24,800 Pa marketing figure refers to the fan/motor rating, not what the lab actually measures at the brush head. Vacuum Wars’ sealed-suction bench test recorded 2.44 kPa (2,440 Pa) and 19 CFM — still above the roughly 0.99 kPa / 17 CFM category average, just nowhere close to the headline number.

Ecovacs Deebot T80S Omni vs Deebot T90 Pro Omni
| T80S Omni | T90 Pro Omni | |
|---|---|---|
| Pet-hair pickup | 100% (perfect) | 100% (perfect) |
| Obstacle avoidance | 21/24 | 23/24 |
| Dried-on stain mopping | 126 points | 157 points |
| Navigation efficiency | 0.62 sq m/min | 0.75 sq m/min |
| Measured suction | 2.44 kPa | 1.23 kPa |
| Price (current) | $657.37 | $499-$899.99 |
Both share a perfect pet-hair score, but the T90 Pro Omni is the more complete machine — faster navigation, better mopping, and a wider price range that includes real sub-$500 sale windows. The T80S Omni’s edge is actually-measured suction, where it beats the T90 despite a lower claimed Pa figure. If pet hair is the only priority and the price is similar, either works; for mopping and overall speed, the T90 Pro Omni is the stronger buy.
Who should buy the Ecovacs Deebot T80S Omni
- Buy it if pet hair and tangle-free brushes are the top priority — its 100%/0% scores are as good as this site has seen.
- Buy it if obstacle avoidance matters more than raw speed — 21/24 is a strong, independently measured result.
- Skip it if you want the fastest possible clean — its below-average navigation efficiency means longer run times than several similarly priced rivals.
- Skip it if mopping dried-on stains is the priority — Ecovacs’ own T90 Pro Omni scores meaningfully higher on that metric for a comparable or lower price.
The bottom line
The Ecovacs Deebot T80S Omni earns its #8 overall ranking (3.92) on Vacuum Wars’ live Top 20 mainly through pet-hair performance and obstacle avoidance, both independently measured and both genuinely strong. Its real weakness is navigation speed — a below-average meters-per-minute result that both Vacuum Wars and Cybershack flagged independently, meaning it takes longer to finish a floor plan than its cleaning numbers alone would suggest. At $657.37, it’s a reasonable pick for pet owners prioritizing pickup power over speed; buyers who want a faster, more complete all-rounder should compare it against Ecovacs’ own T90 Pro Omni first.
