Where each one suits you.

The conditions each robot was assessed against, side by side. Rows marked in gold are where these machines genuinely differ.

Fit verdicts by condition for each robot
Condition Deebot T30S Combo Deebot T20 Omni
Home size
Under 1,500 sqft Good180-minute runtime exceeds typical small-home needs; docking footprint wastes space in compact layouts. GoodCapable but dock requires dedicated space; smaller water tanks mean frequent refills on compact layouts.
1,500 – 3,000 GoodRuntime and suction suit medium homes; scheduled runs handle 2000 sqft in one cycle with dock auto-empty. GoodRuntime and dock capacity align well; ideal for this size range with multi-floor mapping support.
Over 3,000 Depends180 minutes covers 3000+ sqft; multiple runs required. Dock space demands and mop-pad cost scale with larger homes. DependsCoverage achievable but requires large home divided into 2-3 runs; water-tank capacity is limiting.
Primary floors
Hard floors GoodHeated mop pads and 4000 Pa suction optimized for tile, laminate, and sealed hardwood. GoodHot-water wash and AIVI 3D excel on hard floors; mop lift prevents water pooling.
Low / medium pile GoodLiDAR mapping and dual-roller brush handle low-pile carpet systematically; owner reports show consistent performance. GoodLiDAR reads low-pile carpet well; 10.5mm mop lift enables autonomous crossing.
High pile / shagthey differ Depends4000 Pa suction is industry-standard; high-pile carpet requires more frequent brush maintenance and lower mop-pad reliability. PoorOwner reports document reduced effectiveness and brush tangles on high-pile and Berber carpet.

A robot being poor for a condition is a fact about fit, not a fault. “Depends” means the record names a limit worth reading, not that the answer is unknown.
