Up to three

All robot vacuums. Every figure below is placed against the whole class, so a gap can be read against how much the class itself varies.

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 Dreame L20 Ultra Deebot N30 Omni
Home size
Under 1,500 sqft Good120-min runtime covers spaces under 1500 sqft in one pass, but dock footprint occupies 2.5 sqft in compact homes. GoodUp to 320 minutes runtime in quiet mode (manufacturer) comfortably covers compact home layouts in a single cleaning run.
1,500 – 3,000they differ Good120-min runtime handles 1500-3000 sqft in one systematic pass; dock placement is practical in typical layouts. DependsNo published per-charge square-footage coverage exists; 320-minute quiet-mode runtime is the only documented battery figure for mid-size homes.
Over 3,000they differ Poor120-min runtime insufficient for full-home coverage in spaces over 3000 sqft; multiple docking cycles required. DependsAn independent review found the app's automatic room segmentation needed manual correction, a friction that compounds across larger, more complex layouts.
Primary floors
Hard floors Good4000 Pa suction and dual mop pads excel on hard flooring; owner reports confirm effective cleaning without mode switching. GoodAn independent review found it needs added detergent to fully remove tough, dried stains like ketchup or mud.
Low / medium pile Good4000 Pa handles low-pile and berber carpets well; mopping capability extends to threshold transitions between hard and carpet. GoodAn independent review measured very good initial carpet pickup performance on low-to-medium pile flooring.
High pile / shagthey differ Poor4000 Pa insufficient for high-pile or shag carpets; spinning mop pads tangle in long fibers, creating weekly maintenance burden. DependsThe mop pad lifts on carpet detection to avoid wetting rugs, but no independent test measured pickup on high-pile carpet specifically.
Mopping needs
Vacuum only GoodStrong vacuum; the mop lifts or detaches when not needed. GoodStrong vacuum; the mop lifts or detaches when not needed.

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.
