Dyson is a British-Singaporean company which manufactures bagless vacuum cleaners (using cyclonic separation and brushless electric motors), heatless hand dryers, bladeless fans/heaters, and robotic vacuum cleaners.

Technology Dyson has developed various basic technologies for use in their products, including designing and manufacturing its own specialized motors.

Dyson Digital Motor The electric motor marketed as the Dyson Digital Motor (DDM) is a direct current motor, operating on the switched reluctance principle. These brushless motors rotate at up to 110,000 rpm. The motor used a two-pole brushless rotor with a digital controller. Dyson said its efficiency was 84%, which was less than the 96% efficiency that is achieved in some brushless designs. In order to deal with the high speed and centrifugal forces, the impeller is made of carbon fibre reinforced polymer; the shaft is steel.

The first mass-produced version was named "X020" and used in the Airblade hand dryer; the later DDM "V2" was used for Dyson handheld vacuum cleaners. Dyson has continued to develop its proprietary motor designs for various products, improving efficiency for increased battery life, and reducing acoustic noise, resulting in a "V8" version (for cordless vacuums) and a "V9" version (for a hair dryer), .

Root Cyclone technology The Dyson Root Cyclone technology is used in all Dyson vacuum cleaners from DC07 onward. The DC17, DC22, and DC23 use the improved "Root Cyclone & Core Separator", also called "Radix Cyclone", "Intermediary Cyclone", or "Level 3 Root Cyclone Technology".

Most of the current range use "2 Tier Radial cyclones", consisting of two cascaded levels of cyclonic separators to remove dirt and dust without requiring a bag or filter.

Vacuum cleaners

Model names Most versions are identified by a name such as "DC14". Later upright and cylinder cleaners have labels such as "Small Ball" or "Big Ball" which relate to the machine's form factor. Cordless vacuum cleaners are identified by names such as "V11" or "V7" which denote the version of the appliance (the higher the model number, the greater its specification). Older cordless models pre-dating the Dyson V6 have names in the "DC14" style.

Some have submodels identified by a suffix indicating specific facilities, implemented sometimes by additional tools supplied. Suffixes with the same meaning vary from model to model.

All Floors, Multi Floor, Wood+Wool: suitable for both hard surfaces and carpets. Allergy: suitable for filtering out microscopic allergens. Animal: designed to pick up animal hair better than a general-purpose model, and filter out fine particles. Many, but not all of these machines come with a mini turbine tool to help remove pet hair, human hair and cotton fibres from upholstery, cars, and confined areas. Motorhead: cylinder or handheld model with direct-drive motorised brush head. Full Gear: same features as "Animal", with more attachments. Absolute: has a full range of tools and is typically the top-of-the-line model.

Special Edition models Other suffixes may indicate exclusivity to certain stores, e.g. "Comet Exclusive" and "Overdrive" (Comet) or "Blitz it" (Currys).

Some are limited editions:

"Drawing" limited editions These machines feature a different range of tools to the usual "Multifloor" and "Animal" versions and also appear in different colours. The Drawing later became exclusive to the British John Lewis Department Stores.

"De Stijl" limited editions Some of the early Dyson models (DC01, DC02, DC04) were available in a "De Stijl" colour scheme of purple, red and yellow, in homage to the Dutch design movement of the same name.

"Dyson Antarctic Solo" limited editions In 1996, 100,000 recoloured DC01 and DC02 models were produced as part of a fund-raising effort for Ranulph Fiennes's solo expedition to the Antarctic. For these models, the yellow parts found on the mainstream models were replaced with light blue ones, and on the DC02 Antarctic Solo the body was also recoloured in white instead of silver.Dyson, J.

Current models

Upright Model nameLaunch yearDescriptionDC65/UP13/DC662014The DC65 (DC66 in Canada)—is an update of the DC41. The vacuum features an updated root cyclone and a redesigned brush roll with more power than the DC41 and a better edge cleaning system. Some variants (like the Animal model) include the Tangle-Free Turbine Tool. Dyson has undergone a name change to their models, and this appears to be the same base design as the new UP13 model marketed as the "Dyson Ball Allergy". Boxes now contain new product code areas (which may make comparisons slightly easier) in the form [Model Type: UP = upright (previously codes were all DC)] [# ex: 13,19,20,40] [AC = ?] [Marketing description. OR = Origin, ALE = Allergy, AN = Animal, MF2 = Multi-Floor 2, ] [BMR = ?, SSE = ?, IRSY = ?, IRSPU = ?] [Country Code: US]Small Ball (UP15)2015The Dyson Small Ball replaces the DC50 small upright in 2015, after the introduction of the EU 2014 directive on mains powered vacuum cleaners. It is very similar to the DC50, but with refinements to the motor performance, and also a change to the handle wand, which it became a metal wand as on the DC24 to address issues with excessive flexing of the all plastic handle on the DC50.Cinetic Big Ball (DC75/DC77/UP14)2015The DC75 (DC77/UP14 in North America) is Dyson's upright version of the Cinetic vacuum. Contains Cinetic technology with lifetime filters as well as Dyson's auto-adjusting motorized brushroll. The lifetime filters were guaranteed within the 5-year warranty period.Ball (DC41MK2/DC55)2017Updated / renamed version of the DC41MK2 and DC55. Also still known as the DC41 MK2 and also DC55 in certain retail outlets but simply as Dyson Ball from Dyson UKLight Ball (UP22)2017The Dyson Light Ball (UP22) is the replacement for the DC40 (ERP) upright, and is similar to the DC40 ERP in many respects except that it has a totally redesigned powerhead, incorporating a direct-drive, large-diameter brushroll with an internal "epicyclic" geared motor, similar to the DC50 and Small Ball. The powerhead has three levels of suction controlled by a slider switch which opens and closes various valves and gates on the powerhead. It is rated at 700 W and 80 dB, in compliance with the EU regulations 2017 for mains-powered vacuum cleaners. The Light Ball also has a longer reach cable than the DC40 and different tools with the "quick release" red button system.Ball 2 (UP24 in UK and UP20 in the US)2017Models designated "2" incorporate updates and improvements on the original model of their given locale. European models are compliant with the 2017 EU regulations for mains powered vacuum cleaners, and differ in design from non-EU models.

Canister Model nameLaunch yearDescriptionDC632014DC63 is a line of small canister vacuums developed for Asian markets. It uses a Dyson Digital Motor V4 and has 2 Tier Radial Root Cyclones. It is sold in Japan with handle remote operation, a motorized brush bar, and a 'fluffy' hard floor tool.Cinetic Big Ball (CY22)2015The Dyson Cinetic Big Ball canister vacuum features Dyson's new Cinetic technology with lifetime filters. The machine and filters are warrantied for 5 years of use.Big Ball (CY23)2015The Dyson Big Ball (CY23) is a standard cyclonic model with washable filters. Almost identical in appearance to the Dyson Cinetic Big Ball cylinder model.Cinetic Big Ball 22017Models designated "2" incorporate updates and improvements on the original model. European models are compliant with the 2017 EU regulations for mains powered vacuum cleaners and differ in design from non-EU models.Big Ball 22017Models designated "2" incorporate updates and improvements on the original model.
