Dyson vs Shark Cordless: Boxing Day 2026 Buying Guide

For mixed floors, compare the supplied floorheads first, then the tools, handling and full cost of each package. Match them to your floors and furniture before comparing prices.

This manufacturer-based research was checked on 3 October 2026. No matched cleaning test or Boxing Day 2026 price winner is established. Check exact bundles when browsing the wider Dyson and Shark ranges.

What the two packages include

Buying question	Dyson V15 Detect Absolute + Gold 394479-01	Shark Stratos IZ400UK, single battery
Floorheads supplied	Fluffy Optic for hard floors; Digital Motorbar for carpet and hard floors	DuoClean head with two brush rolls, for carpet and hard floors
Upholstery tools	Hair screw tool included	Crevice and multi-surface tools; motorised pet tool is an extra
Listed machine weight	3.1kg	4.1kg
Up-to-60-minute runtime	Eco mode on hard floor; varies with attachment, mode and surface	Eco mode using a non-motorised tool
Charging and batteries	About 4.5 hours; removable click-in battery	About 3.5 hours; one removable battery supplied

The runtime conditions differ, and the weights describe machines rather than handheld use.

If possible, try lifting, steering and emptying each vacuum before choosing one for stairs or frequent carrying.

Check the care instructions for your floors

Your flooring maker’s guidance still matters when a head is advertised for carpet or hard floors. The Dyson V15 manual warns that rotating brushes can affect some surfaces and pile. If fuzzing occurs, it advises using a non-motorised tool and consulting the flooring maker.

The Shark IZ400UK manual, supplied through its exact-model support page, advises trying a hidden area on delicate or wool carpets, particularly loop pile, and keeping the vacuum moving over the carpet while powered on. These instructions qualify the floorhead descriptions; neither machine has been tested here on your flooring.

Include parts and consumables in the decision

Replacement prices can make a difference after the initial purchase. On 3 October 2026, the parts catalogue for Dyson 394479-01 identified the battery and filter below. Shark’s battery listing explicitly names IZ400UK compatibility.

Exact replacement part	Observed price and published delivery calculation
Dyson battery 970938-01	£89.90, including advertised free delivery over £35
Dyson Gold filter 970013-03	£24.90 plus £3 delivery = £27.90 separately
Shark battery XBATR725SLEU	£80.99, including advertised free delivery over £30; charger excluded

These are dated calculations where the stated delivery service applies. Parts stock and a delivery quote for your address were not confirmed. Check compatibility again before ordering; similarly named V15 bundles can use different filters. No fixed annual battery or filter replacement schedule is assumed.

Shark’s manual permits vacuuming without the odour cartridge, but the odour dial must remain installed. Its six-month cartridge replacement recommendation concerns the odour function. Replacement cartridges are therefore an optional cost for that feature, rather than a condition of continued vacuum use.

Check cover and the complete seller offer

Dyson’s guarantee terms give two years for cordless vacuums, with exclusions including normal wear and misuse. Shark’s guarantee information lists five years for the machine with registration and two for the battery in the UK and Republic of Ireland. Its registration instructions give a 28-day window; direct purchases are registered automatically. Terms checked 3 October 2026.

Compare matching bundles at Currys, Amazon and the manufacturers. Record seller, condition, supplied tools, delivery and any additional retailer cover. Compare overlapping guarantee terms rather than adding their periods together. No simultaneously available pair of complete machine-price quotes was verified for this guide.

FAQ

Which model should I shortlist for carpet and hard floors?

Use the package table and your flooring maker’s care instructions to build a shortlist. Compare the tools and handling you need; this research does not establish a cleaning-performance winner.

Does “up to 60 minutes” mean an hour using the powered floorhead?

No. Compare the stated mode and attachments in the table with your intended use. A headline maximum cannot establish your cleaning time.

Should I wait for Boxing Day instead of buying on Black Friday?

Use your replacement deadline and a price you would accept for a suitable package. No like-for-like price history here establishes either event as cheaper for these models. Compare the actual offer with earlier observations and other sellers.

Will a Boxing Day order arrive the next day?

Check the dated estimate for your address, exact product and seller. A normal next-day service does not establish holiday delivery. No Boxing Day 2026 delivery commitment has been verified here.
