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 Neato D8 Ultenic MX50
Home size
Under 1,500 sqft Good100-minute runtime covers compact homes in a single pass without recharging. Good180-minute runtime and a 200 m² rated area leave margin for a smaller home.
1,500 – 3,000 GoodLiDAR mapping handles mid-size floor plans; runtime sufficient for most single-story layouts. GoodMuyComputer cleaned a three-bedroom home twice on one charge; Ultenic rates 200 m² per charge.
Over 3,000 DependsRuntime caps at 100 minutes; large open plans may require multiple sessions without resume-from-dock support verified on all firmware. DependsUltenic rates about 200 m², roughly 2,150 sq ft, per charge; larger homes need a recharge mid-run.
Primary floors
Hard floors GoodD-shape chassis and spiral brush perform well on hard surfaces; edge reach is a documented strength. GoodReviewers found daily cleaning on hard floors effective, with hot-water mop care in the dock.
Low / medium pile GoodSpiral combo brush handles low-pile carpet reliably per owner reports from 2021 to 2022. GoodCarpet detection boosts suction and lifts the mop 15 mm, which SmartWorld says protects low-pile rugs.
High pile / shag DependsOwner reports describe reduced agitation and occasional navigation hesitation on dense 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.

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.
