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.
| Condition | Shark ION Robot 750 |
|---|---|
| Home size | |
| Under 1,500 sqft | Good110-minute runtime covers apartments and small homes under 1,500 sqft in one pass. |
| 1,500 – 3,000 | DependsCoverage is 1,500-2,000 sqft per session; larger homes within this range require dock returns. |
| Over 3,000 | PoorCannot cover sprawling homes in a single session; multiple restarts reduce convenience. |
| Primary floors | |
| Hard floors | GoodLIDAR navigation and 1,500 Pa suction perform reliably on hard floors without obstacles. |
| Low / medium pile | GoodOwner reports confirm acceptable cleaning on low-pile carpet; moderate suction suitable. |
| High pile / shag | DependsSuction drops noticeably on shag and high-pile; owner reports document reduced deep-pile cleaning. |
| Mopping needs | |
| Vacuum only | GoodVacuum-only robot — matches a vacuum-only need. |
| Light mopping | PoorThis model has no mopping function. |
| Frequent mopping | PoorNo mop at all; choose a vacuum-and-mop robot instead. |
| You want to… | |
| Empty bin myself | GoodWeekly brush checks and monthly LIDAR lens wipes are straightforward; routine care is minimal. |
| Empty occasionally | GoodDust bin empties every 2-3 sessions; annual brush replacement costs under $50. |
| Set-and-forget | DependsNo self-emptying dock; manual bin emptying is required. Consider upgrading if hands-off operation is priority. |
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.
What the score is built from.
Nine inputs across three pillars, each weighted as shown and each scored so more is better. A robot can lead on one and trail on another, which is the point of showing them apart.

How far apart is a long way?
A number only means something next to the spread it sits in. Each track is the real range across every classified robot in the class, with the median marked.
These robots share no measured specification with enough published figures to plot. That is a gap in the record, not a finding about the robots.
What the numbers leave out.
Written on each record, and the only thing here every robot on the site carries.
The trade-off
What each design gives up to be good at what it is good at.
Shark ION Robot 750
App scheduling and voice control arrived early for the price tier, but navigation is sensor-reactive, so coverage is approximate and cleaning order is not controllable.
Who each one is wrong for
Stated by the record itself. A robot being wrong for a household is a fact about fit, not a fault.
Shark ION Robot 750
- Homes needing room-targeted or zoned cleaning
- With no mapping, the 750 cannot clean specific rooms or honor virtual zones; physical BotBoundary strips are the only containment tool.
- Users wanting multi-floor persistence without manual intervention
- The 750 stores no map on any floor, so there is nothing to save, switch or resume. Each run is an independent random pass over whatever the robot reaches.
- Owners prioritizing hands-off maintenance
- No self-emptying dock; manual bin emptying required every 2-3 sessions in typical homes.
- Homes with thick or high-pile carpet and heavy pet shedding
- Shark publishes no suction rating for the ION 750, so there is no manufacturer figure to compare it against other machines on. Owner reports document clumping on deep carpet with pet hair.
- Owners wanting the latest firmware support
- Shark has moved focus to newer ION models; older firmware updates are infrequent.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Shark ION Robot 750
- Weekly: Empty dust bin; check primary brush for hair tangles.
- Monthly: Wipe sensor windows with a soft cloth; clean wheel undercarriage.
- Every 3-6 months: Inspect charging dock contacts and clean with dry cloth.
- Annually: Replace primary brush (~$30); replace secondary side brush (~$15).
- As needed: Reposition BotBoundary strips when the furniture layout changes; there is no map to update.
How much each of these is standing on.
Classifications rest on different depths of evidence. A pre-release assessment and a verified one are not the same kind of claim.

Evidence status counts the sources behind a classification, not their kind. A high count can be maker documentation and price coverage, so read it as how much was reviewed rather than as independent testing. How we weigh evidence.
