Dyson DC40 Upright Vacuum Review: Lightweight with Powerful Suction

Dyson is renowned for re-engineering the vacuum cleaner with high-tech innovations. The Dyson DC40 upright applies this advanced thinking into a lightweight, powerful cleaning machine.

In this Dyson DC40 review, we’ll examine its key features, cleaning performance, design, maintenance, and value for UK owners.

Strong Constant Suction

At the heart of the DC40 is Dyson’s patented Root Cyclone technology. Spinning air at high velocities inside the cyclones generates forces of up to 150,000g to remove dust while maintaining strong suction.

The DC40 produces 220 air watts of constant suction that thoroughly cleans deep into carpets. Owners praise how the DC40 eliminates embedded dirt that previous vacuums missed. Uninterrupted power ensures great cleaning across large homes.

Whole-Machine Filtration

In addition to strong suction, the DC40 filters dust and allergens using Dyson’s advanced whole-machine filtration system. This combines a washable pre-motor filter with a HEPA post-motor filter.

HEPA filtration captures particles as small as 0.3 microns, helping remove fine dust and allergens from the air you breathe. Keeping dust contained improves indoor air quality.

Lightweight Ball Design

Weighing just 6.9 kilograms, the DC40 is remarkably lightweight for an upright. Easy steering enabled by Dyson’s signature ball design allows effortlessly maneuvering around furniture and in small spaces.

The low center of gravity provided by the ball prevents tipping over. Combining nimble handling with full-size capacity makes cleaning straightforward.

Motorised Brush Head

The DC40 comes with Dyson’s potent Motorhead cleaner head featuring a motorised brush bar that efficiently deep cleans carpets. Nylon bristles scrub to remove ground-in dirt that accumulates over time.

This motorised system beats basic suction-only heads on carpets, especially for pet hair removal. The brush bar automatically shuts off when reclining for hard floors.

Hygienic Bin Emptying

The DC40’s 0.9 litre bin capacity allows cleaning large areas without frequent trips to the bin. The clear plastic construction lets you monitor debris buildup.

Pressing a button seals dust inside for hygienic disposal. Dyson’s bins don’t require replacement bags that obstruct suction as they fill.

Extensive Attachments

The DC40 comes with a combination tool, stair tool, and articulating hard floor tool for varied cleaning tasks. The carbon fiber extended reach wand provides a 10 metre cleaning radius.

Potential Drawbacks

The DC40 has a narrow cleaning path compared to larger Dyson uprights. As an early ball model, steering takes more effort than newer Dysons. Emptying the bin releases some dust around the base.

Where the DC40 Performs Best

The DC40 truly excels for homeowners wanting:

  • Constant powerful suction across carpets
  • Advanced whole-home filtration
  • Easy manoeuvring around furniture
  • Lightweight upright cleaning
  • Bagless debris disposal

Is the Dyson DC40 Worth the Cost?

With a £200-£300 price tag, the DC40 sits at the lower end of Dyson upright costs. But its cyclone suction power, filtration, lightweight ball design, and attachments create value beyond cheaper brands.

For strong upright cleaning performance without the high cost, the DC40 hits a sweet spot. Dyson power and innovation in an affordable package.

The Verdict

The Dyson DC40 provides outstanding dirt and allergen removal through its cyclone technology and advanced filtration. Combined with accessible steering and maintenance, the DC40 satisfies buyers wanting lasting deep cleaning without breaking the bank.
