LED headlights help you see the dirt so you don't leave any behind.Stick vacuum cleaners are useful around the kitchen and other areas of the home when you have an annoying spill and don't want to get out the dust pan and brush. Easily hidden away in a cupboard, they take up less room than a full-sized vacuum cleaner - and most can be split into two devices, with a handheld vacuum being a part of the stick vacuum. You can also buy a handheld vacuum on its own, to keep for small spills, or for cleaning your car, handbag or even computer keyboards. Some people refer to these as 'dustbusters', after the brand name, although a number of companies make them.

When it comes to vacuum cleaners, power is no guarantee of performance for floor models - it's the overall design of the cleaner that makes the difference. (Stick vacs aren't expected to perform as well at cleaning carpet as a standard vacuum cleaner, at any rate.) But for handheld models (as for most cordless appliances), the more juice in the battery, the better the performance is likely to be.

Look for models that run for a useful length of time and don't take too long to charge. Some may need to charge overnight, or longer. Try out the vacuum in the shop to see if it's all these things; for stick models, check that it moves easily over both carpet and hard surfaces. This should be easy to remove and clean or replace. If you have asthma or allergies, consider a vacuum with a HEPA filter. The standard items to check for are a dusting brush and crevice tools. Other items might include squeegee tools, an extension tube or a pet hair brush. Tools are especially useful if built in or stored on the vac itself, rather than separately or on the charging cradle. These can be used as either a stick or a handheld vacuum. They usually have a trigger to release the handheld vacuum located on the torso of the stick. This allows you to lower the suction, which is handy when cleaning fabric items like curtains or upholstery. Nickel-metal hydride (NiMH) and lithium-ion (Li-ion) batteries are generally more environmentally friendly than nickel-cadmium (NiCd) and lead-acid batteries.

We've found that models with higher voltage batteries - 18V and up - tend to perform better. It's worth checking the warranty details for the battery. Some warranties only cover the battery for a few months, even if they cover the cleaner itself for a year or more. Batteries should last for a few years of typical use, but eventually they will lose their ability to hold a charge. Once that happens, unfortunately you'll likely find that replacing the battery is difficult and costly and it's usually cheaper to just buy another vacuum cleaner. So if the battery can be easily swapped out for a replacement, that's a definite plus. An On/Off switch is easier for continuous operation than a trigger that needs to be held down. This prevents dirt falling back out of the vacuum when you carry it with the nozzle facing downwards, such as when moving between cleaning tasks. A handy mounted base will help to keep the vac readily accessible and fully charged. Some models can suck up wet material or liquids.

However, they can usually only take a fairly small amount (about 150mL) and youshouldn'tfill the bin with liquid past the indicated maximum level. The bin and filter need to be cleaned and dried separately afterwards. This week, Slate is reviewing all the “smart” gizmos we can get our hands on. Read all the entries here. For a guy who has spent his whole career building vacuum cleaners, Nick Grey doesn’t hold a high opinion of most vacuum cleaners. “The first vacuum cleaner, they just made a wooden box, they stuck a motor at one end and a bag at the other, and then they had a tube,” he says. “And the industry has just done variants of that for a hundred years.” Ten years ago, Grey left his post as head of product development at an established British manufacturer to rethink the vacuum from the floor up. This year, his Worcestershire, U.K.–based company came out with a product that he believes represents a leap forward. It’s called the Gtech AirRam, and it’s as delightfully techie as it sounds.

Gtech began by jettisoning the most vexing component of your standard upright vacuum: the cord. Handheld dust-busters can get by with batteries, because they’re not very powerful. But full-size vacuums tend to need cords because it takes a lot of wattage to suck dirt through a brush, around a fan, and all the way up a tube into a dust bag. The AirRam dispenses with the tube and puts the dust compartment right in the head of the vacuum. Now the dirt only has to travel 1½ inches. The power comes from a lithium-ion battery, as in many other high-end consumer electronic gadgets—and electric cars, for that matter. Between its potent battery and relatively low energy demand, it can run for 40 minutes on a single charge, enough to clean a good-sized house. Other features are similarly well-conceived. The brush is more minimal than your typical vacuum brush, requiring less maintenance. The dust is compacted into tidy little blocks that are easy to remove. And the lack of a hose and bag make the handle surprisingly light and agile.

It twists and pivots with a wide range of motion, making it easy to slide under tables or into corners. The whole thing weighs just 7.7 pounds, making it a godsend for the older and frailer among us. A final, geeky flourish is a USB port and software that allow you to hook up the AirRam to your computer and analyze your battery life, energy savings, and even calculate how many calories you burned while vacuuming. Grey says he added that feature as something of a joke, but “people loved it,” so it stayed in the final product. As smart devices go, the AirRam’s analytics are on the gimmicky side. If intelligence is what you’re after, the Roomba is in a different class. But Grey insists the Roomba can’t match the AirRam’s cleaning power. To prove it, the company lent me an AirRam to try out on my home carpets and floors. When I first turned it on, the sound was a little disconcerting. It’s much thinner than the throaty whine of even my relatively lightweight Eureka upright vacuum.

I was actually worried something might be wrong with it. But sounds can be deceiving. The AirRam made light work of my off-white living-room rug, which usually requires multiple passes before it starts to resemble its original shade. It handled my other rugs and hardwood floors with equal aplomb. It worked so well, and was so easy to maneuver, that I began to look around for other surfaces to clean. My eyes alighted on the five-level, 48-inch cat tree in the corner of the room, which is so matted with cat hair that you’d have a hard time guessing that it was once pure white. I’d never think to attempt it with another upright vacuum, but the AirRam was light and maneuverable enough that, on a whim, I gave it a shot. Amazingly, it worked, taking about two years off the cat tree’s appearance. The cat trotted over to examine my handiwork, and I’m probably anthropomorphizing here, but he seemed duly impressed. I will not be purchasing a Gtech AirRam anytime soon, for one reason: It costs $299.
