Short answer
Choose the Aiper Scuba S1 if you want cordless deployment, waterline cleaning and a lighter robot for a standard residential in-ground pool. Choose the Dolphin Nautilus CC Plus Wi-Fi if you clean frequently, prefer not to manage a lithium-ion battery, and value a mature Canadian replacement-parts catalogue.
For most buyers comparing these two exact models, the 2026 Scuba S1 is the easier seasonal appliance — but only after confirming that the Amazon.ca listing contains the current hardware revision and that the seller qualifies for Aiper's Canadian warranty.
Canadian pool owners comparing the Aiper Scuba S1 and the Dolphin Nautilus CC Plus Wi-Fi are really comparing two different ownership philosophies, not just two robots. The Scuba S1 is cordless: charge it on land, drop it in, and pull it out when the cycle ends. The Nautilus CC Plus is corded: it plugs into a deck-side power supply and can run cycle after cycle without ever stopping to recharge. Neither approach is objectively better; the right pick depends on how often you clean, how much you mind lifting a heavier robot, and whether you would rather manage a battery or a floating cable.
How we researched: This is a specifications- and ownership-based comparison, not a claim that we personally tested both robots side by side in the same pool. We reviewed current Aiper Canada and Maytronics Canada product pages, warranty and authorized-seller policies, official parts listings, model-year documentation and current Amazon.ca listings. Manufacturer figures are useful for compatibility checks, but they are not guarantees for every pool.
Specifications can also change by production batch and model year. The Scuba S1 in particular has gone through multiple hardware revisions since 2024, and Dolphin pool-length claims vary across current Canadian pages and retail listings. Confirm the exact model and revision before ordering.

The Two Contenders
Aiper Scuba S1 — Best for Most Buyers
The Scuba S1 wins the day-to-day convenience comparison. Charge it on land, select a mode, place it in the pool, and remove it after the cycle. There is no long cable drifting behind the robot, no power-supply position to plan and no swivel to inspect.
Coverage and runtime: Current Aiper specifications cover up to 1,600 square feet or 50 feet in length, with floor, wall and waterline operation. The 2026 revision is rated for up to 180 minutes in a normal cleaning cycle, while the current Amazon.ca listing advertises up to 240–270 minutes in its lower-duty Eco maintenance pattern.
Weight: Aiper specifications list 5.8 kilograms for the Scuba S1, versus 9.45 kilograms for the Nautilus CC Plus — a meaningful difference when lifting a wet robot from below the waterline.
What to know before buying: Scuba S1 has a battery that will age, a three-to-four-hour charging interval, and hardware differences across its 2024, 2025 and 2026 revisions. Its app cannot maintain normal Wi-Fi communication underwater. Confirm exactly which revision and filter configuration a seller is shipping before ordering.
Bottom line: The easier seasonal appliance for a standard residential pool, provided you verify the revision and authorized seller. Check price on Amazon.ca
Dolphin Nautilus CC Plus Wi-Fi — Best for Frequent, Long-Term Cleaning
The Nautilus CC Plus trades convenience at the pool edge for predictability over many cleaning cycles. Its power supply stays on the deck and feeds the robot through an anti-tangle swivel cable, so there is no internal cleaning battery to recharge before the next run.
App and scheduling: The MyDolphin Plus connection is handled through the powered deck-side system, so remote starts and weekly scheduling are more practical than an app that loses Wi-Fi once its cordless counterpart submerges.
Parts and ownership: Maytronics Canada's current catalogue is the strongest reason to consider Dolphin. Compatible filters, brush assemblies, tracks, power supplies and a universal caddy are identifiable by part number. That does not guarantee a cheap repair, but it is a better ownership signal than a product whose sealed power system may depend primarily on whole-unit warranty service.
What to know before buying: The trade-offs are the floating cable, greater lifting weight, no waterline scrubbing, and a current Canadian product page listing only a one-year warranty. Confirm the exact product number for pool length and whether a caddy is included in your bundle.
Bottom line: The more conservative long-term choice for pools that need repeated or back-to-back cycles. Check price on Amazon.ca
The Seven Differences That Matter
1. Cordless convenience versus unlimited repeat cycles
The Scuba S1's biggest benefit is visible before it starts cleaning: there is no cable in the water. That makes setup simpler around irregular decks, furniture and pool covers, eliminates one source of tangling, and avoids a floating cord crossing the swimming area during the cycle. A retrieval hook is included.
The battery does change the routine: charge for roughly three to four hours, select the cleaning mode while the robot is out of the water, place it in the pool, retrieve and drain it after the cycle, rinse the basket, and let the charging area dry before recharging for the next session.
The Nautilus CC Plus uses a power supply and swivel cable instead. Once it is safely connected, it can run a two-hour default cycle without battery-range anxiety and can begin another cycle without a multi-hour charging pause. Corded does not mean “leave it forever” — owners still need to follow the manual, clean the filter, inspect the cable and remove or store the robot as required, and never swim while either cleaner is operating.
Choose Aiper when: one scheduled cycle normally handles the pool and cable-free use will make you deploy the robot more often. Choose Dolphin when: storms, trees or a busy pool create enough debris to require repeated or frequent cycles.
2. Scuba S1 cleans the waterline; Nautilus CC Plus does not
Maytronics Canada's specification table lists the Nautilus CC Plus for floor and wall coverage only, and explicitly states Waterline Scrubbing: No. That distinction is easy to miss because a wall-climbing robot may reach the top of the wall — reaching the boundary does not necessarily mean travelling laterally and scrubbing the waterline as a dedicated cleaning zone.
Aiper positions the current Scuba S1 for four-zone coverage: floor, walls, waterline and compatible shallow areas, using caterpillar-style treads, one active PVC roller and WavePath 2.0 patterns. Waterline coverage can reduce manual brushing where sunscreen, body oils and airborne residue collect, but it does not eliminate hand cleaning entirely — the robot may not reach behind ladders or fittings, tile scale and hardened mineral deposits still need appropriate treatment, unusual transitions can interrupt traction, and a stated waterline mode does not guarantee complete coverage in every pool shape.
If a visible waterline ring is one of your main frustrations, the Scuba S1 is the clear winner between these two.
3. Scuba S1 is lighter to lift
Aiper's published Scuba S1 specifications list a robot weight of 5.8 kilograms. Maytronics Canada lists the Nautilus CC Plus at 9.45 kilograms — a 3.65-kilogram dry-weight difference that is substantial when the cleaner must be lifted from below the waterline. Both robots retain some water briefly during retrieval, so allow them to drain at the wall before completing the lift.
The weight advantage matters most for owners with shoulder, hand or back limitations, pools where the robot is removed after every cycle, storage that is not immediately beside the pool, and anyone carrying the unit downstairs for winter storage. Never lift either robot by its floating power cable, charging port or delicate components — follow the supplied retrieval method and use the handle once the unit is within reach.
4. The filtration numbers require context
The Scuba S1's current product page lists a 3.5-litre debris basket, a 180-micron fine filter and 3-micron MicroMesh ultra-fine filtration. Its 2026 upgrade documentation describes the MicroMesh insert as optional, while the current Amazon.ca title advertises dual filtration — meaning the filter should be checked in the box contents, not inferred from the model name alone.
The Nautilus CC Plus uses a top-access ultra-fine system. Current Canadian Maytronics copy describes filtration down to 70 microns and lists compatible replacement panels and filter assemblies.
Three microns sounds automatically superior to 70 microns, but nominal mesh size is not a complete real-world filtration score. Results depend on whether the correct insert is actually installed, filter area and water bypass, how quickly the medium clogs, flow under load, debris type, cleaning duration and pool circulation, and whether particles are suspended or settled. The Scuba S1 has the finer nominal option for silt and very small particles; the Dolphin has the clearer Canadian replacement-filter path and a simpler specification history. For leaves and twigs, basket volume, inlet design and how often the filter is emptied may matter more than the smallest advertised micron number.
5. Their water-flow figures are close
Aiper publishes 4,200 gallons per hour, equivalent to approximately 15,900 litres per hour. Maytronics Canada publishes 17 cubic metres per hour, equivalent to 17,000 litres per hour. Those manufacturer figures are close enough that they should not decide the purchase on their own.
Water movement is only one part of debris removal. Brush contact, route coverage, inlet geometry, filter loading, wall traction and pool shape all affect the result, and cross-brand laboratory methods may also differ. Be wary of comparisons that declare a winner by converting a single flow or suction figure and ignoring the entire cleaning system.
6. Their apps do different jobs
The current Scuba S1 supports app-based mode selection, cleaning history and over-the-air updates. Aiper's own troubleshooting documentation says the robot disconnects from Wi-Fi when submerged, which is expected. In practice, the app is primarily a before-and-after interface: configure the robot near the network, choose the mode or periodic program, and review information when it reconnects.
The Nautilus CC Plus uses the MyDolphin Plus app with its powered system. Maytronics advertises remote starting, monitoring and weekly scheduling, and because the power supply remains above water and connected, the app is more useful during pool operation. Neither app gives perfect underwater remote driving — the Nautilus CC Plus specification table lists no handheld remote control, while the Scuba S1's ordinary Wi-Fi cannot function as a live underwater connection. Choose based on cleaning and ownership first; a pool robot app should not outweigh compatibility, retrieval, parts and warranty.
7. Aiper has the longer listed warranty; Dolphin has the stronger parts signal
Aiper Canada's policy lists 24 months for the Scuba S1, restricted to the country of receipt and purchases through official or authorized channels. Aiper identifies Amazon.ca as an authorized digital channel, but the individual marketplace seller still needs checking. Maytronics Canada's current Nautilus CC Plus product page lists one year. On warranty length alone, Aiper wins.
On visible Canadian parts, Dolphin wins. Maytronics lists model-compatible fine and ultra-fine filter components, brush assemblies, tracks and guide-wheel components, a replacement power supply, a universal caddy, and manuals, repair requests and dealer support. This creates an important split: Aiper offers longer protection during the first two seasons, subject to seller eligibility, while Dolphin offers a shorter listed product warranty but a stronger signal for ownership after warranty. Before buying, ask what happens if the Scuba S1's battery no longer holds adequate runtime after the warranty ends. For the Dolphin, price the cable or power supply rather than assuming every repair will be economical.
Which Robot Fits Your Canadian Pool?
A standard in-ground pool cleaned once or twice per week: Choose the Scuba S1. The cordless workflow is likely to create the greatest everyday benefit, current coverage and runtime claims are ample for many residential pools, and the lighter body is easier to remove after each cycle.
A pool under trees or after frequent storms: Choose the Nautilus CC Plus. Heavy leaves may require the filter to be emptied and another cycle started, and corded power makes back-to-back cleaning easier because there is no three-to-four-hour recharge between sessions. Neither cleaner skims floating leaves from the surface — a pool's built-in skimmer or a separate surface robot still has that job.
A pool with a persistent waterline ring: Choose the Scuba S1. It provides a dedicated waterline capability that the Nautilus CC Plus does not; hardened calcium and scale still require appropriate manual treatment.
A pool used almost every day: Lean toward the Nautilus CC Plus. Its weekly scheduling and no-charge design are better suited to repeated use, and the cable becomes the price of routine readiness. Remove the cleaner before people enter the water, and follow manufacturer instructions for storage and chemical-treatment periods.
A cottage or seasonal Canadian pool: The Scuba S1 is easier during the season; the Dolphin may be easier over many winters. The cordless Aiper is convenient to bring out for a quick cycle, but a lithium-ion battery needs correct off-season charging and temperature-controlled storage — leaving it depleted in a freezing shed can permanently reduce capacity or create a safety issue. The Dolphin has no cleaning battery to preserve, but its robot, cable and power supply still need clean, dry, protected indoor storage.
A long pool near the stated limit: Confirm the exact model before buying. Aiper lists the Scuba S1 for 50 feet / 15 metres. The main Maytronics Canada Nautilus CC Plus page lists 12 metres (roughly 39 feet), while other current Canadian Maytronics copy and Amazon.ca describe up to 50 feet. That discrepancy can reflect different product numbers, bundles or updated copy — ask the seller to confirm the manufacturer's maximum for the exact unit on your invoice.
Important note about the 2026 Scuba S1
The Scuba S1 is a model family, not one permanently fixed specification. Aiper's current upgrade guide describes three generations: the 2024 version has no Wi-Fi or app and a fixed two-hour cycle; the 2025 version adds app and Wi-Fi features with up to 150 minutes of runtime; and the 2026 version offers up to 180 minutes, OTA updates and 3-micron MicroMesh compatibility.
The current Amazon.ca ASIN referenced in this article advertises app support, OTA upgrades, dual filtration and extended Eco runtime, which points to the newer configuration. Nevertheless, marketplace inventory can mix batches, so before purchase: ask whether the listing is the 2026 hardware revision; confirm whether the 3-micron MicroMesh insert is included or sold separately; save the product-page screenshot and invoice; check the serial number and hardware information immediately after delivery; and return an older or mismatched unit within the retailer's window rather than accepting missing features.
This verification is particularly important when a discount seems dramatically better than all other Canadian sellers.
Winter Storage and Battery Ownership
Canadian winter changes this comparison more than a summer specification table suggests.
Aiper Scuba S1
- Remove it from the pool and rinse away pool chemicals.
- Let the robot and charging connection dry completely.
- Charge and store it according to the current manual.
- Keep it in a dry, temperature-controlled location.
- Do not charge a wet, damaged, swollen or frozen battery system.
- Use only the approved charger.
- Check the manual for the recommended maintenance-charge interval.
Dolphin Nautilus CC Plus
- Rinse and dry the robot, filter and cable.
- Coil the floating cable loosely without sharp bends.
- Store the power supply away from water and weather.
- Protect the robot, brushes and tracks from freezing and prolonged sun.
- A compatible caddy can reduce cable strain and simplify indoor storage.
The Dolphin avoids traction-battery degradation, but cables, seals, brushes and electronic components still age regardless of which robot you own.
Amazon.ca Buying Checklist
For either model:
- Confirm the exact product title and model number.
- Check the seller — not only the fulfilment company.
- Verify that the seller is authorized for Canadian manufacturer service.
- Confirm whether the item is new, renewed, open-box or imported.
- Read the written Canadian warranty before ordering.
- Save the invoice and listing screenshots.
- Verify included filters, charger or power supply, retrieval hook and manuals.
- Inspect the unit before putting it in chemically treated water.
- Do not rely on a temporary coupon when deciding which architecture suits your pool.
For the Scuba S1 specifically, confirm the model year and MicroMesh contents. For the Nautilus CC Plus, confirm the pool-length rating and whether a caddy or cover is included.
How We Chose These Comparisons
We evaluated these two robots based on manufacturer specification accuracy across current Aiper Canada and Maytronics Canada product pages, ownership factors like runtime, charging, cable management, weight and warranty, cleaning coverage claims placed in context rather than treated as decisive on their own, Canadian availability and support including warranty terms and parts catalogues, and model-year accuracy given that the Scuba S1 name spans multiple hardware revisions.
Frequently Asked Questions
Is the Aiper Scuba S1 better than the Dolphin Nautilus CC Plus?
The Scuba S1 is better for cordless convenience, waterline coverage, lower lifting weight and the longer listed Canadian warranty. The Nautilus CC Plus is better for repeated cycles, live deck-side app connectivity and long-term parts visibility. There is no universal winner; the right choice depends on how often you clean and which compromise you can tolerate.
Does the Nautilus CC Plus clean the waterline?
The current Maytronics Canada specification table says no. It cleans the pool floor and walls only. Buyers who need lateral waterline scrubbing should choose another Dolphin tier or the Scuba S1, after confirming compatibility with their pool.
How long does the Aiper Scuba S1 run?
The 2026 product specifications state up to 180 minutes for normal battery operation. Current Aiper and Amazon.ca marketing also describes as much as 240 to 270 minutes in an enhanced Eco maintenance pattern. Do not interpret the Eco figure as one continuous maximum-power floor-and-wall cycle.
Can the Aiper app control the Scuba S1 underwater?
Normal Wi-Fi disconnects after the robot submerges, according to Aiper's support information. The app is useful for pre-set modes, history and updates when connected, not continuous live underwater control.
Does the Dolphin Nautilus CC Plus need charging?
No. It runs from its deck-side power supply through a floating cable and can perform another cycle without any battery-charging downtime.
Which cleaner is easier to lift out of the pool?
The Scuba S1. Its published dry weight is 5.8 kilograms, compared with 9.45 kilograms for the Nautilus CC Plus. Let either robot drain at the wall before lifting it completely from the pool.
Which one filters finer debris?
The Scuba S1 offers a nominal 3-micron MicroMesh option alongside its 180-micron basket. The Nautilus CC Plus uses an ultra-fine system described at 70 microns in current Canadian copy. Confirm that the Aiper MicroMesh filter is included; nominal micron figures alone do not guarantee better real-pool filtration.
Which one has the better Canadian warranty?
Aiper Canada currently lists 24 months for the Scuba S1 purchased through an eligible channel. The current Maytronics Canada Nautilus CC Plus page lists one year. Confirm coverage for the exact seller and retain the invoice.
Can either robot replace normal pool filtration?
No. A robotic cleaner collects settled debris and scrubs compatible surfaces. It does not replace circulation, chemical balance, sanitization, skimming or the pool's primary filtration system.
Can I leave either robot in the pool all season?
Do not assume so. Follow the exact manual, remove the cleaner before swimming or chemical shock treatments, empty the filter and protect components from unnecessary chemical and weather exposure. Scheduling features do not make permanent immersion maintenance-free.
Bottom Line
Buy the Aiper Scuba S1 if the absence of a cable will make you use the cleaner more often and your pool benefits from waterline coverage. The 2026 version's 180-minute normal runtime, lighter body, fine-filtration option and two-year Canadian warranty create a strong package, provided you verify the revision and authorized seller.
Buy the Dolphin Nautilus CC Plus Wi-Fi if your priority is repeatable cleaning over several seasons. The cable is less elegant, but it eliminates charging downtime and connects the robot to a mature Maytronics parts ecosystem.
Our practical recommendation: for a typical residential pool, choose the Scuba S1. For frequent cleaning or heavy debris, choose the Nautilus CC Plus. For long-term repairability over cordless convenience, choose the Nautilus CC Plus. For waterline cleaning and easier lifting, choose the Scuba S1.
