All robot pool cleaners. 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 | Polaris 9450 Sport | Hayward TigerShark QC |
|---|---|---|
| Pool type | ||
| In-ground | GoodDesigned specifically for in-ground pools; 4WD and wall-climbing brush are optimized for this geometry. | GoodStandard in-ground operation; random pathing works well in pools under 15k gallons with consistent pump schedules. |
| Above-groundthey differ | PoorManufacturer specifies in-ground pools only; drive configuration is not compatible with above-ground pool walls. | GoodSuction cleaners pair directly with above-ground pump filtration; no separate equipment required. |
| Mixed setupthey differ | DependsCapable only on the in-ground pool in the setup; does not cover any above-ground pool sharing the installation. | GoodWorks with either pool type, provided pool size stays under 15k gallons and floor is stable. |
| Pool size | ||
| Small (< 400 sqft) | GoodCovers pools well under 50 feet; 90-minute cycle completes full coverage with capacity to spare. | GoodRandom pathing naturally recycles the floor; small pools see consistent weekly coverage with light debris loads. |
| Medium (400 – 800)they differ | GoodSystematic gyroscopic navigation handles mid-size in-ground pools up to 50 feet within a single 90-minute cycle. | DependsPool size around 12k–15k gallons benefits from 8+ hour daily pump schedules; shorter cycles risk coverage gaps. |
| Large (> 800) | Poor60-foot swivel cable limits pool length coverage to 50 feet; pools exceeding that require a longer-cable model. | PoorPools over 15k–20k gallons show unvisited dead zones; random pathing cannot ensure complete coverage. |
| Debris load | ||
| Fine (sand / silt)they differ | GoodVortex Vacuum Technology draws fine sediment and particles into the 5L canister effectively. | Poor100-micron mesh basket clogs rapidly with fine silt or algae; fine debris forces daily basket empties instead of weekly. |
| Leaves / large debristhey differ | GoodExtra-large 5L canister handles leaf debris without mid-cycle full-canister pauses in most moderate-debris pools. | DependsModerate leaf load manageable with weekly emptying; heavy seasonal leaf fall requires two to three empties per week. |
| Algae / heavy foulingthey differ | GoodSolid-blade scrubbing brush scrubs floor, wall, and waterline surfaces where algae accumulates. | PoorActive algae blooms clog the fine-mesh basket within hours; unsuitable for pools experiencing algal blooms without chemical treatment. |
| Coverage you want | ||
| Floor only | GoodSystematic floor coverage is the baseline function; gyroscopic navigation reduces missed strips. | GoodPurpose-built for floor cleaning with fine-mesh debris capture; operates unattended on level floors. |
| Floor + wallsthey differ | Good4WD enables wall climbing; manufacturer specs include wall coverage as a documented capability. | DependsFloor cleaning is effective; walls and steps require separate manual tools or a dedicated wall-climbing cleaner. |
| Floor + walls + waterlinethey differ | GoodSolid-blade scrubbing brush reaches the tile line and waterline surface; owner reports describe effective waterline scrubbing. | PoorNo built-in capacity for wall or waterline cleaning; random pathing keeps the cleaner on the pool floor. |
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.

Not compared, because fewer than two of these robots carry a published figure: Runtime, Charge time, Noise.
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.
Polaris 9450 Sport
The 7-day timer is the only scheduling interface: no remote start, no app override, no on-demand cycle without a manual power reset.
Systematic gyroscopic navigation covers the pool methodically, but the 60-foot cable imposes a hard 50-foot pool-length limit; larger pools require a longer-cable model.
Hayward TigerShark QC
You get full-basin cleaning with no programming overhead, but every session starts and ends by hand: the unit is carried to the water, started, lifted out, and the cartridge rinsed.
Two fixed cycles and nothing between them: four hours for a full clean, or 90 minutes on Quick Clean. No scheduling, no pause and no app, so the choice is made at the deck each time.
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.
Polaris 9450 Sport
- Above-ground pool owners
- Manufacturer specifies in-ground pools only. Drive track configuration and cable management are designed for in-ground shapes. Above-ground pool walls and entry points are not supported by the drive system.
- Pools longer than 50 feet
- The 60-foot swivel cable constrains operational radius. Pools exceeding 50 feet in length may not receive full systematic coverage in a single 90-minute cycle, leaving uncleaned zones.
- Owners requiring remote or on-demand spot cleaning
- The 9450 has no handheld remote and no app trigger. Cleaning runs only per the 7-day timer or a manual power cycle. The step-up 9550 Sport adds a handheld remote for on-demand control.
- Owners wanting Wi-Fi scheduling or app-based monitoring
- No iAquaLink, no Wi-Fi module, no companion app of any kind. The programmable timer is the sole scheduling method. A networked pool-cleaner alternative is required if app connectivity is a priority.
- Pools without a 120V GFCI outlet near the pool edge
- The control unit requires a 120V GFCI outlet. Pools without this outlet require electrical work before installation. Cordless robotic pool cleaners are the alternative for sites without accessible GFCI power.
Hayward TigerShark QC
- Above-ground pools
- Hayward sells and rates the TigerShark QC for in-ground pools only, and the model name carries Inground at every retailer. Above-ground use is outside what the machine is sold for.
- Pools with persistent fine algae or silt loads
- The cartridge loads quickly with fine debris under heavy conditions, so rinsing moves from after each run to during it. Algae blooms and clay-heavy surroundings keep the owner in the loop.
- In-ground pools larger than 20 x 40 ft
- Hayward's rated coverage is 20 x 40 ft. Larger basins are outside the rating; that is a size limit rather than a coverage-pattern problem.
- Owners wanting scheduled or remote-controlled operation
- The QC runs the cycle you start, then stops. No scheduling, pause, resume or app control; manual placement and start are required each session.
- Pools without a GFCI-protected outlet within reach of the 55 ft cord
- The transformer runs from a grounded, ground-fault-protected receptacle and the cord is 55 ft. Closing a gap with an extension lead is not an acceptable option on a pool cleaner; an outlet in reach has to be installed by an electrician.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Polaris 9450 Sport
- After every use: Remove unit via Easy Lift System, rinse 5L top-load canister under garden hose, reinsert canister before storage.
- After every use: Lay cable out flat or coil loosely to prevent set-in tangles before next cycle.
- Monthly: Inspect drive tracks for debris embedding or visible wear; rinse track channels clean.
- Every 3-6 months: Inspect swivel cable along full 60-foot length for kinks, cracks, or connector wear.
- Every 3-6 months: Inspect scrubbing brush for wear and replace if waterline scrubbing effectiveness has declined.
- Seasonally: Drain and dry unit before off-season storage; do not store with water in the internal chambers.
- As needed: Reprogram the 7-day timer after power outages or daylight-saving-time changes.
Hayward TigerShark QC
- After each run: Unplug the transformer, lift the unit out, open it and rinse the reusable cartridge with a garden hose.
- Monthly: Check the brushes and drive tracks for wear and clear hair or fiber from the rollers.
- Every 3-6 months: Inspect the full length of the 55 ft cord for nicks and cracked insulation, and the transformer connector for corrosion. A damaged cord takes the machine out of service.
- Annually: Before storage, rinse the unit and the cartridge, let both dry fully, and keep the machine and the transformer indoors over winter.
- As needed: Replace the cartridge if the media tears or stops seating; replace brushes when they no longer make contact with the surface.
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.
