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 BISSELL FlexClean Fur… Roomba Plus 515 Combo
Home size
Under 1,500 sqft Good180-minute runtime comfortably covers this footprint in one run, per the manufacturer's stated battery life. GoodA 295-minute, 2,000 sq ft rating per charge covers a home this size in one run.
1,500 – 3,000they differ DependsAn independent review found no dedicated camera-based obstacle avoidance, so clearing cords first matters more as area grows. GoodiRobot rates a charge at 2,000 sq ft, covering most homes in this range in one run.
Over 3,000 DependsNo published coverage-per-charge figure exists for homes this large; the 180-minute runtime's recharge-and-resume behavior is undocumented. DependsRated 2,000 sq ft per charge, and recharge-and-resume behavior is not documented for this model.
Primary floors
Hard floors GoodThe mop pad lowers automatically on hard floors and dispenses BISSELL's proprietary cleaning solution while cleaning. GoodSpinning DualClean pads at 180 RPM with SmartScrub target dried spills on sealed hard floors.
Low / medium pile GoodThe mop pad automatically raises when it detects carpet, and the NeverTangle brush roll targets hair wrap. GoodCarpet detection lifts the pads 10 mm before crossing rugs, per iRobot.
High pile / shag DependsNo independent test of high-pile suction performance was found; only automatic carpet-detection pad lift is documented. DependsA 10 mm pad lift may not clear dense pile, and no independent carpet test exists for this model.
Mopping needs
Vacuum only GoodVacuums first; the mop pad is optional. GoodStrong vacuum; the mop lifts or detaches when not needed.
Light mopping GoodFlat mop pad handles light, routine wiping of hard floors. GoodActive mopping system covers routine floors easily.
Frequent moppingthey differ DependsA dragged pad freshens floors but lacks the pressure or scrubbing for heavy, frequent mopping. GoodPressure or rotating mop with self-wash is built for frequent mopping.
You want to…
Empty bin myself GoodThe bagless HEPA base still self-empties, but you'll refill cleaning solution and rinse the mop pad by hand. GoodHands-on upkeep is light; the dock handles debris, water and pad washing.
Empty occasionally GoodThe bagless HEPA base holds debris up to 8 weeks, matching an occasional-emptying preference well. GoodOwner tasks come down to brush checks, adding solution and a tank service every few months.
Set-and-forgetthey differ DependsNo dedicated camera-based obstacle avoidance means floors need pre-clearing each run, working against a true set-and-forget routine. GoodiRobot rates the dock for up to three months without emptying bins or handling water.

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.
