Shark Detect Pro IW1511UK Review: Light and Clever, Tiny Bin
Shark’s sensor-led stick vacuum weighs 2.76 kg, turns its own suction up at dirt and skirting boards, and has fallen from a £349.99 launch price to £175. The catch everyone agrees on is a 0.4-litre bin — and the 60-minute run time on the box is an eco-mode figure, not what you get in the mode you will actually use.
Where the reviews line up
We drew on three sources: a home test of this exact UK model by Ideal Home, a measured test of the closely related US version by Vacuum Wars, and Argos customer ratings — 4.3/5 from 373 reviews when we checked on 11 October 2026. They agree on more than they disagree.
Three things come up everywhere. It is light and easy to steer: Ideal Home found it easy to push around, and Vacuum Wars called it one of the lightest cordless sticks it has tested. The sensors do something useful — suction rises on its own when the head meets dirt or a skirting board, and both testers rate the edge cleaning. And the brushroll copes with hair: Vacuum Wars found its anti-tangle combs worked nearly flawlessly.
Two caveats are just as consistent. The bin is small — 0.4 litres on Shark’s spec, and Ideal Home found it filled quickly on carpet. And run time depends on the mode. Shark’s “up to 60 minutes” is measured in eco mode with a non-motorised tool. TechRadar’s UK tester was down to one battery bar after about 20 minutes in Detect mode, and Vacuum Wars got just under 15 minutes on maximum power from the US version.
At £175 it is good value for a light, clever stick for a flat or a small house with mostly hard floors. If you have a lot of carpet, pets or stairs, the bin and the run time on boost will annoy you sooner than the price will.

Before the review: which Detect Pro?
Shark sells the Detect Pro as the vacuum on its own, IW1511UK, and in the past with an auto-empty base: IW3510UK (1.3-litre base) and IW3611UK/IW3611UKT (2-litre base). We have reviewed IW1511UK because it is the one Shark UK still lists and the one Argos has the most reviews for. When we checked, John Lewis showed the IW3611UKT as no longer available online. Argos has a listing whose search title says “Detect Pro Auto Empty 1.3L”, but the page itself is now headed “PowerDetect Pet Pro Auto Empty” — a different machine. Check the model number before you pay. In the US the same vacuum is sold as the IW1111, with a smaller battery claim.
Specification at a glance
| Spec | Figure | Confidence |
|---|---|---|
| Run time, eco | Up to 60 minutes | Shark’s claim, “tested in ECO mode, with non-motorised tool” |
| Run time, Detect mode | One battery bar left after about 20 minutes | TechRadar’s UK test; not a run-to-flat figure |
| Run time, maximum | Just under 15 minutes | Vacuum Wars, measured on the US version (Shark US claims 40 min on low) |
| Power modes | 3 | Euronics listing |
| Bin | 0.4 L (Shark) · 0.42 L (Euronics, Currys Business) | Two published figures; Vacuum Wars measured about 330 ml on the US version |
| Weight | 2.76 kg (Shark, Ideal Home) · 2.68 kg (TechRadar) | Sources differ; neither says what is included |
| Charge time | 4.5 hours | Currys Business listing; Euronics gives “4.5” with no unit |
| Battery | Removable 21.6 V lithium-ion, charges on or off the vacuum | Currys Business (voltage); Shark (removable). Capacity in Wh not published |
| Noise | 82 dB (Euronics listing) · 76 dB in use, 69 dB for the auto-empty base (TechRadar) | Two figures from two methods; neither is Shark’s own |
| Running cost | Under 3p a full charge; under £10 a year charged daily | Our sum at 26.32p/kWh, using a generous 100 Wh from the wall — see below |
| Dimensions | 70.8 × 26.4 × 35.3 cm (H × W × D) | Euronics listing; allow room for the wall clip and charger |
| In the box | Vacuum, 20 cm duster-crevice tool, charger, base clip, one battery | Shark |
| Auto-empty base | Not included with IW1511UK | Sold as IW3510UK / IW3611UK bundles; base was £399.99 with the vacuum at launch (Ideal Home) |
| Guarantee | 5 years when registered with Shark; batteries 2 years | Shark; Euronics words it as 1 year plus a 4-year warranty |
| Price | £175 at Argos (was £200) · £199 indicative at Euronics · RRP £349.99 | Checked 11 October 2026; RRP is the launch price quoted by Ideal Home and TechRadar |
What it costs to run (our sum). Shark does not publish the battery’s capacity in watt-hours, so we have used a deliberately high 100 Wh drawn from the wall per full charge, charger losses included. At the October 2026 Ofgem cap of 26.32p per kWh that is 2.6p a charge, or £9.61 a year if you ran it flat and recharged it every single day. The real figure will be lower. Electricity is not the running cost to worry about here; the battery is, and it carries only a two-year guarantee.
Ideal Home
Who they are: Molly Cleary is Kitchen Appliances Editor at Ideal Home, where she has worked since 2022 after editorial roles at Real Homes, Homes & Gardens and Livingetc; her profile describes four years of product testing and lists appliances and cookware as her specialism, so this is an experienced home tester rather than a lab.
This is a hands-on test at home rather than a measured one — there are no run-down times or dB readings — but it is the one source that used the exact IW1511UK sold here. The verdict is warm. Cleaning is described as great, especially on hard floors, and the tester was pleasantly surprised on carpet. She noticed the suction rising by itself on difficult patches, such as a rug under a sofa, and found edge cleaning better than on Shark’s Stratos, which she puts down to the shape of the floorhead.
The criticisms are the ones you will hear again. The bin is much smaller than the Stratos’s and fills quickly on carpet, though it is very easy to empty, and the floorhead can sometimes get stuck. On battery she says the charge “lasts for absolutely ages”, and lists a “true 60 minutes” among the pros. She does not say what mode that was in, so read it next to Shark’s own eco-mode footnote.

A structured test across twelve factors. Probably the US version (IW1111 family), which has the same floorhead and sensors but a different battery claim.

Who they are: Christopher White is CEO of Vacuum Wars, which his profile describes as a YouTube channel dedicated to vacuum reviews that has spent eight years building its own in-house database of vacuum test results; that makes it a specialist with measured numbers, though it tests US models and the profile does not say how long he has tested personally.
Vacuum Wars bought the US Detect Pro — the vacuum, one crevice tool and a storage clip — which is the same machine as IW1511UK apart from the battery claim: Shark US quotes 40 minutes on low against 60 minutes in eco here. Its most useful number is the one Shark does not print: just under 15 minutes on maximum power. It also measured the bin at about 330 ml, smaller than either UK figure.
The praise is specific. The QuadClean floorhead is responsive and well balanced, the anti-hair-tangle combs worked nearly flawlessly in its tests, and pairing a dust sensor with floor-type detection is something the reviewer says he had not seen before. Sealed HEPA filtration, LED rings that show how much dirt it is picking up, and edge sensors also get credit. Against that, raw power came out below average in several tests even though pickup held up, the top-mounted light did little to show debris, and the run time on max is below average. The verdict: very light and very good value, but not for everyone because of the battery and the bin.

Who they are: Argos’s star ratings are written by its own shoppers on its product pages; we could not read its review policy, so treat them as unverified customer experience and weigh the pattern across many reviews rather than individual comments.
373 reviews is the biggest pool of owner opinion we found on this model in the UK, and an average of 4.25 out of 5 is solid without being suspiciously perfect. The Argos page loads its review text in the browser, so we could read the score and the count but not the individual comments. We have not quoted any owner, and we would not lean on the score for anything more than “most buyers are happy”.
An older snapshot of the same listing on Latest Deals showed 4.4 from 124 reviews, so the score has come down slightly as the number of reviews has tripled. That is normal as a product moves past its early buyers. The £175 price has also turned up before. Latest Deals logged Argos at £175 against £349.99 earlier, and AO at £159 for paying members. So treat £175 as a normal sale price, not a one-off.

What holds up
- Light — 2.76 kg on Shark’s figure — and easy to steer, praised by both testers.
- Suction rises on its own at dirt and at skirting boards, so edges get cleaned better.
- Anti-hair-wrap brushroll that a specialist tester found worked almost flawlessly.
- Removable battery you can charge off the vacuum, from any socket.
- Five-year guarantee when registered.
- Often £175, half the £349.99 launch price.
What people complain about
- 0.4-litre bin that fills quickly on carpet.
- 60 minutes is an eco-mode figure; expect closer to 15 minutes on maximum.
- Few tools in the box: one duster-crevice tool, no motorised pet tool.
- The floorhead can get stuck, and debris can collect behind it (TechRadar).
- Battery guarantee is only two years.
- No auto-empty base in this version, and the bundles are harder to find.
If you are cross-shopping: our Shark Stratos IZ400UK review covers the older Shark with the bigger bin that Ideal Home compares it to. The Dyson V15 Detect is the sensor-led stick it is usually measured against, at a much higher price. For more run time, see the Bosch Unlimited 7 or the Gtech AirRam Platinum. If you have a lot of floor to cover and would rather not watch a battery gauge, a corded cylinder like the Henry HVR160 is still the cheap, simple answer.
Who it actually suits
Buy it if you live in a flat or a smallish house with mostly hard floors and a few rugs, you want something light enough to grab for a ten-minute tidy, and long hair wrapped round the brushroll has put you off other vacuums. At around £175 it is a lot of well-reviewed technology for the money.
Look elsewhere if you have wall-to-wall carpet, a moulting dog or several flights of stairs. There the small bin and the short run time on boost will have you emptying and recharging mid-clean. Spend more on a bigger-bin stick, or get a corded cylinder.
What we could not check
- The videos were confirmed by search listing, not by opening them. Each watch link and title appeared in two differently worded searches; YouTube itself cannot be fetched from here. Two of the three channels were not named in the listings, and all three probably show the US version.
- Run time in Detect and boost modes on the UK model. No source ran the IW1511UK flat in each mode. The 15-minute maximum figure is from the US version, and the 20-minute Detect figure is a battery-bar reading, not a run-down test.
- Battery capacity. Shark publishes 21.6 V but not watt-hours, so our running cost uses an assumed 100 Wh ceiling.
- Noise. The 82 dB comes from a retailer listing and the 76 dB from TechRadar’s own test; Shark publishes no figure and we cannot say how either was measured.
- Weight. Shark says 2.76 kg and TechRadar 2.68 kg; neither says whether the battery and tool are included.
- Argos review text and seller. The listing loads its reviews and its “sold by” line in the browser, so we could read the score and count but not the comments or who the seller is. Argos is now partly a marketplace.
- Stock. Shark UK still lists IW1511UK but its page did not show a price or stock status when we checked; Currys’ business site showed it out of stock and Euronics’ £199 is an indicative price before postcode.
- Shark’s own current price. The £349.99 RRP is the launch price quoted by Ideal Home and TechRadar; we could not read a current price on Shark’s page.
- Which?’s verdict. Which? has a Detect Pro test page, but its scores sit behind membership and we have not used them.
