Dyson is a British manufacturer specializing in vacuum cleaners, air purifiers, fans, and hand and hair dryers. They offer a broad selection of stick/handheld vacuums but have also developed canister vacuums as well as more conventional uprights. Regardless of design, they all feature the company's proprietary cyclone technology, which eliminates the need for a dirt bag.
The best Dyson vacuum with a cordless design that we've tested is the Dyson V11 Animal. This stick/handheld excels on bare floors as it can easily pick up pet hair as well as cereal and rice. Its performance on low and high-pile carpet is also very good overall. It has good maneuverability and you can even reconfigure it into a handheld if you need to clean inside your car. It also comes with a wide variety of tools and brushes such as a turbo brush and a soft-bristle brush for cleaning more delicate surfaces. It's easy to assemble and it has virtually no recurring costs as long you maintain it.
While it has a plasticky build quality that makes it feel a little fragile, this design helps keep it lightweight. It also charges pretty slowly and you could be waiting up to four hours to get a full charge. It lasts around eight minutes on its most powerful 'BOOST' setting, which may not be enough if you need to clean a big spill. Luckily, you can get over 70 minutes of continuous vacuuming time if you use its less powerful 'Eco' setting. That said, this cordless vacuum offers versatile performance and its lightweight design.
The Dyson Ball Animal 2 is the best Dyson vacuum for carpeted surfaces that we've tested. This corded upright delivers an outstanding cleaning performance on low and high-pile carpet, as it's capable of sucking up pet hair as well as small and large debris without issue. Its performance stays fairly consistent as its dirt compartment fills, while its self-adjusting head automatically lifts and lowers to suit shaggier or lower-lying carpets. Because of its corded design and bulky construction, it isn't quite as easy to carry around as other Dysons, but it does have a long power cord and a wide array of attachments to help you get to hard-to-reach areas. You can even detach the upright wand from the body, though the rest of the machine has to be positioned upright for it to work. Also, it has virtually no recurring costs, as long as its filters are well-maintained.
Unfortunately, its build quality is mediocre, with a mainly plastic construction that feels a little flimsy. It's a little hard to disassemble and put back together since it doesn't have easy-clip mechanisms, which allow parts to be quickly clicked into place. There's also an onboard storage rack, but it only has room for a couple of the included tools, which is somewhat disappointing. Still, if you're looking for something that can easily manage heavily-carpeted surfaces, this is a great choice.
The best Dyson vacuum for bare floors that we've tested is the Dyson Cyclone V10 Absolute. This stick/handheld is highly effective in sucking up everything from pet hair to small debris like baking soda, not to mention larger, denser objects like cereal and sand. It can be reconfigured into a handheld vacuum by simply removing its wand and comes with a good variety of specialized cleaning brushes and tools. Combined with its cordless, lightweight design, it's easy to reach small, out-of-the-way areas as well as shelves and furniture. Since it lacks a dirtbag and comes with a HEPA filter meant to last the lifetime of the machine, there are virtually no recurring costs to worry about.
Unfortunately, despite being fairly easy to take apart and reassemble, user maintenance is still somewhat difficult due to the large number of parts that need regular cleaning. Also, if you have a difficult mess to clean and need maximum suction power, the battery will drain very fast, as it can run out of charge in less than 10 minutes if used continuously on its 'BOOST' setting. That said, normal battery life is decent overall.
Dyson produces a decently large variety of vacuum cleaners that work quite well on different surfaces, though you should expect to pay a hefty premium for that performance and versatility. Most offerings in their lineup are fairly maneuverable, easy to carry around, and come with a wide variety of brushes, but build quality is usually quite plasticky, and user maintenance is a little on the finicky side. In comparison, most Shark vacuums feel slightly better-built but perform worse on carpeted surfaces. Dyson vacuums tend to be stronger and more consistent performers on all surface types than those from BISSELL.
Dyson specializes in producing vacuum cleaners, air purifiers, fans, and hand and hair dryers. They offer a broad selection of stick/handheld vacuums but have also developed canister vacuums and conventional uprights. They don't incur any recurring costs due to the implementation of Dyson's cyclonic technology across their lineup, which eliminates the need for a dirt bag while also filtering out allergens. As a general rule, Dyson vacuums are fairly lightweight, maneuverable, and versatile. That said, they also usually have a long list of parts to regularly clean, plasticky build quality, and, on cordless models, somewhat limited runtime on high-power modes.
