In homes over 2,000 sq ft, small cleaning inefficiencies compound quickly. A model that recharges twice mid-clean, or forgets its map on the third floor, is a much bigger problem than in a small apartment.
These picks are ranked specifically on battery life, multi-floor support, and mapping stability at scale.

Final verdict
Roborock Qrevo S5V suits buyers who prioritise most homes. Worth knowing: Suction and obstacle avoidance are a step below the Saros flagships.
Battery life and recharge-and-resume
In a 3,000 sq ft home, a robot vacuum will almost certainly need to recharge mid-clean. Every LiDAR model can now recharge-and-resume — the robot returns to the dock, charges to a set threshold, and picks up exactly where it left off.
Look for 150+ minute battery life and confirmed recharge-and-resume support.
Multi-floor mapping
Every current premium model supports at least 3-4 saved floor plans. You carry the robot upstairs, it recognizes the floor from its scan, and picks the right map automatically. Older models required manual map switching in the app.
Roborock, Dreame, and iRobot all handle multi-floor mapping well. Ecovacs is close behind. Shark's multi-floor support is more basic and less reliable at scale.
Suction and brush design
Suction is quoted in Pascals (Pa), and current models range from figures that are not published at all up to ratings above 20,000Pa. Treat these numbers with care: brands measure suction in different ways, so a higher rating does not automatically mean better cleaning. Brush design, edge coverage and carpet boost matter at least as much.
Brush design matters just as much. Dual rubber roller brushes (iRobot, Roborock premium) resist hair tangles far better than traditional bristle brushes. If you have long-haired pets, this feature alone is worth the upgrade.
Mopping capability
There are three tiers of mopping. Basic pass-through pads (Eufy 11S, Roomba Combo j5) dampen and wipe — fine for light dust. Vibrating sonic pads (Roborock, Dreame) apply pressure and simulate a proper wipe. Rotating spinning pads on premium flagships (Roborock Saros 10R, Dreame L20, Ecovacs X2) genuinely lift stuck-on residue and are the only pad system that comes close to a manual mop.
If you have hardwood or tile as your primary flooring, spinning-pad mopping is a category-defining upgrade.

Final verdict
For most large homes, the Roborock Saros 10R is the pick — fast mapping, reliable recharge-and-resume, and a dock that handles weeks of debris. If battery life is the primary constraint, the Dreame L40 Ultra Gen 2 edges ahead.
