Robotic pool cleaner battery life: what the runtime claims mean, by mode
Short answer: most box runtimes are best-case figures for a single mode. Across the 20 battery-powered cleaner records in our data, maker headline runtimes run from 90 to 300 minutes for floor or unstated modes [C]. Only 3 of the 20 have a runtime that a named independent reviewer says they timed or observed: about 120 minutes for the WYBOT C2 (Bob Vila), 100–185 minutes depending on mode for the WYBOT C2 Vision (eftm), and more than 210 minutes for the Beatbot AquaSense 2 (Freshly Charged, a lower bound). We don’t time robots ourselves. This page sets out what makers claim, labels the mode every time, and shows where reviewers’ numbers exist.
Key findings
- 3 of 20 battery-powered cleaner records have a runtime figure that a named independent reviewer says they timed or observed. Three more reviewer figures exist (Beatbot Sora 10, Aiper Scuba X1, Aiper Scuba V3), but each falls short of that test for a reason we explain below, so we show them and don’t count them.
- 9 of 20 attach a mode to the headline figure and 8 don’t. The Aiper Scuba S1’s page is one of the 8: it gives 150 minutes for Floor mode next to an unlabeled 180. The other 3 (Aiper Scuba S3, Dolphin Liberty line, Polaris Freedom Plus) have no runtime figure on a maker page we could read.
- One model has a timed figure for every mode. eftm reported the WYBOT C2 Vision at 175–185 minutes in Eco, in line with WYBOT’s 180-minute Eco claim, and at 100–170 minutes in the other seven modes.
- Beatbot is the only brand whose pages we opened that splits floor from walls and waterline (Sora 10: 300 vs 240 minutes [C]). None of the Aiper, WYBOT or Mammotion pages we opened gives a figure for walls and waterline.
The three models a named reviewer timed
Labels: [C] claimed by the maker · [M] timed or observed by a named third party · [R] retailer-listed or retailer-authored. “n/s” = mode not stated. Percentages are our calculation (reported ÷ claimed).
The three models a named reviewer timed: maker claim vs reviewer figure
| Model | Claim [C] | Measured [M] | By whom, date | What the comparison can and can’t say |
|---|---|---|---|---|
| WYBOT C2 | 180 min · Eco (floor-focused) | about 120 min · mode n/s | Bob Vila (Paul Rankin), May 6, 2026: battery life “came in right around the 2-hour mark during my testing” | 120 ÷ 180 = 67%. The reviewer doesn’t name the mode, so this isn’t an Eco-to-Eco comparison. |
| WYBOT C2 Vision | 180 min · Eco | Eco 175–185 · Floor 115–120 · Standard full pool 135 · Wall 125–140 · Waterline 125–170 · Wall then Floor 120–130 · Turbo 100–105 · Dirt-hunting 115 | eftm.com (Rob Rigby), Jan 27, 2026 | Two units, each run from 100% to the low-battery warning, in one pool. It’s the only per-mode set we found, and it’s for the C2 Vision, not the C2. |
| Beatbot AquaSense 2 | 240 min · floor; about 210 min · walls (Beatbot comparison page) | more than 3.5 h (over 210 min) with battery left · mode n/s | Freshly Charged, Feb 24, 2026 (author not named): “In our test, we got over 3.5 hours of runtime and still had juice left” | A lower bound, not a run to empty. The Pool Nerd (Aug 20, 2025) said it “barely got a full cleaning cycle” and gave no figure. |
WYBOT C2 Vision: eftm's timed runtime in every mode
Reviewer figures we show but don’t count
| Model | Claim [C] | Reviewer figure | Source, date | Why it doesn’t count as a measurement |
|---|---|---|---|---|
| Beatbot Sora 10 | 300 min · floor only; 240 min · floor + walls + waterline | Cleaning results held “even after nearly five hours of cleaning, including walls and the waterline” | PCWorld (Christopher Null), Jun 12, 2026 | PCWorld describes how long it cleaned. It doesn’t say that was one charge, and it doesn’t give a stop point. |
| Aiper Scuba X1 | 180 min · mode not stated | “can run for more than 2.5 hours at a time” (at least 150 min) | AOL (Camryn Rabideau), updated Aug 26, 2025 | It’s a lower bound, and the article doesn’t say the tester timed it. The same article lists “180 minutes” as the spec. |
| Aiper Scuba V3 | 180 min (3 h) · mode not stated (Aiper support page; the product page gives no runtime) | 140–150 min, floor + walls + waterline, timed to waterline parking | Digital Phablet, no publication date on the page | The page gives a timing method, but it carries no date, credits its photos to another publication and gives two different test lengths (two weeks and a month). We can’t confirm who ran the test. |
| Aiper Scuba S1 | 150 min Floor · 180 min spec table (mode n/s) · 270 min “Enhanced Eco” banner | about 150 min, Auto mode | Reviewed.com (Nick Woodard), Jun 18, 2024 | Reviewed.com let it run “for about 150 minutes, as the manual claims”, so that’s the maker’s figure, relayed. We show it as per the manual, as quoted by Reviewed.com [C]. |
| Aiper Scuba S1 | (as above) | battery “consistently ran out around the 40 to 45-minute mark” | Poolbots, Jun 17, 2026 | Retailer report [R]. Poolbots sells competing robots and gives no method, mode or pool. It also says Aiper advertises about 60 minutes, which isn’t what Aiper’s page says. |
A Gadgeteer figure for the AquaSense 2 Ultra (about 4.5 hours) appeared only in a search summary we didn’t open, so we don’t use it.
The full table: all 20 battery-powered cleaners
The last column is our calculation from maker claims, not a performance measurement. It divides the claimed floor or headline minutes by the maker’s claimed pool area in thousands of square feet, which shows how generous an area claim is next to the runtime claim. It says nothing about how well a robot cleans. We don’t calculate it when the area is retailer-listed, the maker’s runtime figures conflict, or the figure is surface-only.

Notes: charge times are maker claims unless marked. Most maker pages don’t publish battery capacity. Figures marked [R] or “unverified” come from retailer or search-result listings and are shown for reference only.
Corded reference. A corded robot has no battery, so there’s no runtime to compare. The Dolphin Nautilus CC Plus has a default 2-hour cycle on the Maytronics residential page, and another Maytronics listing says 3 hours [C]. US retail listings give a 60 ft cable [R]. Its maximum pool is 40 ft on one Maytronics page and “up to 50 ft” on another [C]. Cycle length is how long the programmed clean lasts, not a limit set by a battery.
Why box numbers mislead
Eco and floor-only modes
Many headline figures are for the gentlest mode. WYBOT’s C2 page gives one runtime, 180 minutes in Eco mode, which it describes as floor-focused, and none for any other mode [C]. Aiper’s Scuba S1 page describes Eco as 45-minute cycles every 48 hours [C]. PCWorld describes the same Eco pattern for the Beatbot Sora 10 (June 12, 2026) and the Aiper Scuba S1 Pro (July 1, 2024). When a figure doesn’t name its mode, we write “mode not stated” rather than guess.
Eco schedules and weekly timers cap the total
Two limits have nothing to do with battery capacity. First, a 45-minute Eco cycle every 48 hours works out to three or four cycles a week, or 135 to 180 minutes of cleaning (our calculation). Second, The Pool Nerd (March 12, 2026) read the WYBOT C2’s weekly floor timer in the app as totalling 180 minutes a week, split into 60-, 40- and 30-minute sessions. That was read from the app, not timed, and the article’s session numbers don’t agree with each other, so treat it as low confidence. WYBOT’s page says the app schedules up to four cleanings a week [C]. If you run the robot on a schedule rather than in one long run, the box runtime may never be the limit.
Conflicting figures on the same maker page
- Aiper Scuba S1: aiper.com’s own page shows 150 minutes in Floor mode, 180 minutes in the spec table and a 270-minute “Enhanced Eco” banner [C]. The page says its test data are theoretical. We show all three and don’t pick one.
- Aiper Scuba S3: Aiper’s page says only “extended runtime”. A comparison site lists 240 minutes and a European retailer lists 180 [R]. We don’t present either as a maker claim.
- Aiper Scuba SE: 90 minutes in the spec table and “a full 100 minutes” elsewhere on the same page [C].
- Mammotion Spino E1: 210 minutes on Mammotion’s US page [C]; a German retailer lists 240 [R].
- Beatbot Sora 10 charging: about 3.5 hours at 65 W on Beatbot’s page [C]; The Pool Nerd cites 4.5 hours from the manual, which we couldn’t view.
Walls and waterline cost runtime on some pages and not others
Beatbot’s own figures show the cost directly. The Sora 10 drops from 300 to 240 minutes when walls and waterline are included, a 60-minute (20%) drop [C]. The AquaSense 2 Ultra drops from 300 to 270 minutes, or 10% [C]. On the AquaSense 2, Beatbot’s comparison page gives about 3.5 hours for walls against 4 hours for floor [C]. The AquaSense X lists 300 minutes for both floor and walls plus waterline [C].
Beatbot's own figures: floor-only vs walls and waterline runtime
Reviewers’ numbers don’t follow one clean rule. The Pool Nerd called the WYBOT C2’s wall and waterline runs “noticeably shorter” but gave no minutes (March 12, 2026). In eftm’s set for the C2 Vision, Wall mode (125–140 minutes) and Waterline mode (125–170 minutes) ran longer than Floor mode (115–120 minutes). That’s one pool and two units, and the reviewer doesn’t explain it. Mode names don’t tell you which mode drains the battery fastest, so check the figure for the mode you’ll use.
Surface-skimming minutes are not cleaning minutes
Several headline numbers are surface-only: the Aiper Scuba V3 Ultra at 480 minutes, the Aiper Scuba X1 Pro Max at 600, the Beatbot AquaSense 2 Ultra and AquaSense X at 600, and the Beatbot Sora 70 at 420 [C]. These are minutes spent skimming the water surface. They don’t tell you how long the robot cleans the floor or walls, so we leave them out of the floor comparison and the last column of the table. Dedicated skimmers will get their own guide.
How we collect measurements
- Sources, in order: maker manuals and pages for claims. Named reviewers for measurements, with name, date and what they say they observed. Retailer content is labeled as retailer content and never counted as independent.
- What counts: a figure counts as a measurement only if the reviewer says they timed or observed it. A maker figure repeated by a reviewer, including a run “for as long as the manual claims”, stays a claim. We don’t use figures with no stated origin, and undated pages whose authorship we can’t confirm don’t count.
- What we leave out: expired-domain and parasite listicles, and brand blogs offered as proof that one robot beats another.
- Send us one: if you have a timed runtime with the mode, model, date and a way to check it, use the contact page. We’ll add it with attribution, or tell you why it doesn’t qualify.
- Updates: the date at the top shows when we last re-checked these figures. Changes are listed on the corrections page.
FAQ
How long do cordless robotic pool cleaners run? Leaving out surface-only figures, maker claims in our data run from 90 minutes (Aiper Scuba SE) to 300 minutes [C]. The 300-minute claims are floor-only for the Beatbot Sora 10, AquaSense 2 Ultra and AquaSense X and the Aiper Scuba X1 Pro Max, floor for the Sora 70, and mode not stated for the Sora 30. Three models have a figure a named reviewer timed: about 120 minutes (WYBOT C2, Bob Vila), 100–185 minutes by mode (WYBOT C2 Vision, eftm), and more than 210 minutes (Beatbot AquaSense 2, Freshly Charged, a lower bound).
Why does my robot run shorter than the box says? The data points to three reasons. The headline figure is often for Eco or floor-only mode. Wall and waterline modes cost runtime on some models. Eco cycles and weekly schedules split the total. The table gives the mode next to every claim where the maker states one.
Does wall and waterline cleaning drain the battery faster? On Beatbot’s published figures, yes for the Sora 10 (300 to 240 minutes, 20%) and the AquaSense 2 Ultra (300 to 270 minutes, 10%) [C]. Beatbot lists no drop for the AquaSense X. In eftm’s per-mode set for the WYBOT C2 Vision, Wall and Waterline ran longer than Floor.
How long does a pool robot take to charge? Maker-claimed charge times in our records run from about 3 hours (WYBOT C2, C2 Vision and C1; Aiper Scuba SE) to about 4.5 hours (Beatbot AquaSense 2 Ultra and AquaSense X) [C]. Many pages publish no charge time. Charge only as your manual describes, with the supplied charger.
Is a corded robot better for big pools? A corded robot runs a programmed cycle (2 hours by default on the Dolphin Nautilus CC Plus page [C]) and has no battery to run down. Its limit is cable length against pool length, listed as 40 or 50 ft on Maytronics pages. We don’t rank one type above the other here. A full cordless vs corded comparison is planned.
