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 iRobot Roomba Max 715 Ultenic MX50
Home size
Under 1,500 sqft GoodCapable but self-empty dock is overkill for compact homes; smaller J7 or budget model sufficient. Good180-minute runtime and a 200 m² rated area leave margin for a smaller home.
1,500 – 3,000 GoodFlagship positioning; covers 1500-3000 sqft in 1-2 scheduled runs with dock self-empty. GoodMuyComputer cleaned a three-bedroom home twice on one charge; Ultenic rates 200 m² per charge.
Over 3,000 Depends120-min runtime may require two passes on 3000+ sqft homes without breaks; schedule multiple runs. DependsUltenic rates about 200 m², roughly 2,150 sq ft, per charge; larger homes need a recharge mid-run.
Primary floors
Hard floors GoodSealed hard-floor performance strong; pre-filter and cliff sensors handle transitions well. GoodReviewers found daily cleaning on hard floors effective, with hot-water mop care in the dock.
Low / medium pile GoodHistorical j-series strength; 8500 Pa suction covers low-pile and standard carpet reliably. GoodCarpet detection boosts suction and lifts the mop 15 mm, which SmartWorld says protects low-pile rugs.
High pile / shagthey differ PoorOwner reports on iRobot models document suction loss and motor strain on shag and high-pile carpet. DependsThe mop lifts only 15 mm, and no reviewer tested deep or high-pile carpet.
Mopping needs
Vacuum only GoodVacuum-only robot — matches a vacuum-only need. GoodStrong vacuum; the mop lifts or detaches when not needed.
Light moppingthey differ PoorThis model has no mopping function. GoodActive mopping system covers routine floors easily.
Frequent moppingthey differ PoorNo mop at all; choose a vacuum-and-mop robot instead. GoodPressure or rotating mop with self-wash is built for frequent mopping.
Upkeep you accept
Regular upkeep GoodAbout 90 minutes of upkeep a month. GoodAbout 60 minutes of upkeep a month.
Some upkeepthey differ DependsAbout 90 minutes of upkeep a month, which is over an hour. GoodAbout 60 minutes of upkeep a month.
Minimal upkeepthey differ PoorAbout 90 minutes of upkeep a month, which is over an hour. DependsAbout 60 minutes of upkeep a month. Minimal is 30 or less.

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.
