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 Robot Vacuum X20+ Roomba Plus 575 Combo
Home size
Under 1,500 sqft Good120-minute runtime covers single-floor apartments; multi-floor execution requires two sessions. GoodCompact 11.93 x 3.29 x 11.73 in chassis and LiDAR mapping comfortably cover a smaller single-level home in one scheduled run.
1,500 – 3,000they differ GoodCovers typical two-floor homes in one session with 20-30 minutes reserve. Multi-room scheduling supported. DependsiRobot has not published runtime or recharge-and-resume specs for this SKU; mid-size single-level coverage is not independently confirmed.
Over 3,000 Depends120-minute runtime may require two sessions on 3,000+ sqft layouts. Capable but dock placement becomes critical for mid-run returns. DependsNo documented runtime or multi-session resume exists for this SKU; large single-level coverage above 3,000 sqft is unconfirmed.
Primary floors
Hard floors GoodMop function optimized for sealed hard floors. LiDAR performs reliably on wood, tile, and laminate. Good25,000 Pa suction and LiDAR-mapped navigation are well suited to consistent hard-floor debris pickup and coverage.
Low / medium pile GoodSuction and mop-lift both adequate for low-pile carpet. Manufacturer specs document effective fiber engagement. Good25,000 Pa suction handles standard low-pile carpet pickup, and mop pads auto-lift about 10mm on carpet detection.
High pile / shagthey differ PoorSuction drops significantly on high-pile and shag carpet. Owner reports document 2x+ pass requirement for visible cleanliness. Depends25,000 Pa is iRobot's compact-tier suction, below its higher-suction combos; thick high-pile pickup is not independently documented.
Mopping needs
Vacuum only GoodStrong vacuum; the mop lifts or detaches when not needed. GoodStrong vacuum; the mop lifts or detaches when not needed.

You want to…
Empty bin myself GoodMonthly dock drain purging and filter cleaning required; mop pads every 4-6 months. Not fully hands-off despite auto-dock and auto-empty features. GoodAutoWash Dock automation is optional for hands-on owners; manual bin emptying and pad rinsing remain available if preferred.
Empty occasionally GoodScheduled maintenance aligns with mixed expectations. Weekly bin check and monthly drain cleaning fit typical semi-autonomous routines. GoodDock automation covers dustbin emptying and mop-pad wash and dry cycles; owners still handle periodic detergent and water refills.
Set-and-forget DependsDock automation reduces frequency but does not eliminate hands-on work. Monthly drain and quarterly mop-pad replacement contradict true hands-off operation. DependsiRobot documents months of hands-off maintenance, but the dock's water reservoir and detergent supply still need periodic manual refills.

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.
