Keep in mind that battery life can vary depending on the settings and attachments that you use, so it might not always be exactly what the manufacturers list. Of the vacuums we tested, the median runtime on low was 33 minutes and 15 seconds, while the median runtime on high was just 9 minutes and 43 seconds. (Generally, most models did not last as long as their advertised runtime.) Most cordless vacuums come with a variety of attachments—like crevice tools and dusting brushes—that make them even more versatile. During our testing, we frequently had to reach for crevice tools to get in the tight corners of staircases and between the cushions on upholstered furniture. You can also use these special attachments to clean curtains, vents, and more. Do not charge the battery or the appliance outside of the temperature range specified in the instructions. Charging with the wrong power adapter rating or at a temperature outside of the specified range may damage the battery and increase the risk of fire. To optimise the battery life: When not in use, keep the appliance at room temperature between 18°C (64°F) to 28°C (82°F). The ambient temperature range for operation and charging should be between 1 o•c (50°F) to 30°C(86°F) In my opinion, the Belife S11's performance speaks for itself. However, I also found the cleanup and maintenance outstanding. Cleanup
Many—but not all—of the vacuums on our list have high-efficiency particulate air (HEPA) filters, which trap small particles and allergens and prevent them from recirculating in the air. If you're in the market for a lightweight vacuum cleaner, then a cordless vacuum is the way to go. They're much more compact than traditional upright vacuums, so they're easier to maneuver—and you don't have to worry about finding an outlet before you start cleaning. DO NOT twist your wrist or raise your shoulder/arm excessively to vacuum at an awkward angle. This may cause injury to your muscles/ joints
Each mode offered outstanding results, regardless of the surface (I tried wood and tile, too). I was also pleasantly surprised at how quiet the vacuum sounded, regardless of which mode I tried. Even in hyper mode, the vacuum cleaned up more debris with less noise than my traditional vacuum. When shopping for cordless vacuums, one of the most important factors to consider is battery life. “For an apartment or a small house, you want to choose a vacuum with a battery life of at least 30 [minutes],” says Samson. “Some vacuums go up to over an hour in run time and these are great for larger homes, but for most of us, 30 minutes of run time should be plenty to clean the floors in our home.” We especially appreciate this vacuum’s strong suction power, which didn’t decrease throughout the testing period. It’s also pretty lightweight and easy to maneuver, according to our tester, who says it “was easy to push around and under the furniture.” It transitioned from hardwood to carpet easily, too.
And since hair is notoriously difficult to clean even with some of the top vacuums, we also sprinkled wig hair—including short strands to resemble pet hair and long strands to resemble human hair—on those same surfaces. For carpeted surfaces, we made sure to press down so that the hair became embedded in the carpet. Testers then evaluated how much hair each cordless vacuum could remove from the various surfaces in a minute. Once completed, they inspected the brushroll for tangled hair—and if there was, they removed the hair and took note of how easy it was to clear with their hands, scissors, or an included tool (if applicable). WARNING! DO NOT lean the vacuum against any surface (wall, edge of table, cabinet, etc) in upright position for support at any time in case it accidentally slips and falls, causing damage to the main body,. Use only genuine spare parts and accessories from. Using other types of batteries may explode, causing damage and injury to persons. This cordless vacuum also worked well on medium-pile carpets, although it was difficult to get into the crevices of stairs without an attachment. During testing, we found that it was a little awkward for this vacuum to transition between floor types (it seemed to stop suctioning for a second), and it didn’t perform quite as well on hardwood and grout. “It works slightly better on the carpet, because on the hard surface, it tends to push things around,” says our tester. This cordless vacuum’s head is slightly bulkier than some others we tested, which made it a little harder to clean in tight spaces without using the crevice tool. Still, it was pretty easy to use: “The vacuum maneuvers well around objects, making sharp corners,” our tester says. “However, it may miss smaller objects, like popcorn kernels, in the recessed spaces transitioning from one surface to another. The brush head is 2.5 [inches] high, so won't fit under anything more narrow than that, like furniture with short legs.”To find the best cordless vacuums, we regularly evaluate the latest models in our Lab. Our latest test spanned four days and involved testing 15 cordless vacuums—but we’ve evaluated dozens more over the past year using a similar rigorous testing process. If necessary, e.g. accidentally run through sugary liquid, wash the brush with running water . Remove the bearing cap before washing. DO NOT soak the fluffy brush. Technical Specifications TROUBLESHOOTING WARRANTY POLICY Documents / Resources Dyson claims this vacuum has a runtime of 20 minutes, which we found to be surprisingly accurate: In our tests, it ran for 21 minutes on low power (8.5 minutes on high) before the battery died.
For optimal performance, it is recommended to clear the dirt bin after every use. Always keep the filters clean Replace the pre-motor filter and HEPA filter yearly or whenever the air flow is weak even after proper cleaning and drying One unique feature of this vacuum is its customizable configuration. While many cordless vacuums can transform into a handheld model, this one takes it a step further by allowing you to choose where you want the base of the unit: either on top for better reach under low-lying furniture or at the bottom so the vacuum is less top-heavy. Just keep in mind that at 8 pounds, this Miele cordless vacuum is heavier than most of the other models on our list—but we still found it fairly lightweight. And while the advertised battery life for this vacuum is 60 minutes, our tests found that it only lasted 33 minutes on the lowest setting before running out of power. Please read this manual carefully before using this product. We hope you enjoy using this product as much as we enjoyed developing it and using it daily. Unfortunately, the battery doesn't last forever. It is rated to operate for just 50 minutes on a single charge, and my testing found that to be pretty accurate. Although this meant I couldn't get through all three stories of my townhouse at once, it was easy enough to recharge the battery and keep going. Cleanup and Maintenance Once the vacuums were fully charged, testers evaluated the runtime of each model by vacuuming a medium-pile rug on the lowest power setting until the battery died, recording the time with a stopwatch. We then swapped the dead battery with a fully charged spare battery and repeated this test using the highest power setting.
The biggest disadvantage of cordless vacuums is that they can only run for so long before they need to be charged. Of course, the battery life varies depending on the settings. Higher settings (like max modes) give you some "extra power for carpeting," according to Morse. But they'll drain the battery much faster than lower settings (which are sufficient on bare floors). Just take note that when you first make the switch to a cordless vacuum, you might notice a difference in performance. "A battery unit cannot give you the same amount of suction as an electric vacuum," says Morse. If you have a large home and like to clean it all at once, then we suggest choosing a cordless vacuum with a removable battery so that you can buy an extra, keep it charged, and swap it as needed. To change direction significantly (e.g. vacuum between chairs) move your legs and body to change direction so that your body is always perpendicular to the To find the best cordless vacuums, we thoroughly tested dozens of models in our Lab and evaluated them based on their effectiveness on multiple surface types, noise level, battery life, overall value, and more. We even put their maneuverability to the test by setting up a “living room” obstacle course, complete with furniture, rugs, and floor lamps. For expert tips on choosing a cordless vacuum, we spoke to Len Morse, president of Vacuum World; Jessica Samson, cleaning expert of The Maids; and Leanne Stapf, COO of The Cleaning Authority.
Stapf agrees that a vacuum’s compatibility with attachments is one of the most important things to consider. “Some accessories or attachments may [include] different types of brushes or suctions,” she says. “Some may even have a mop-like feature, which you can utilize on non-carpet flooring. These options can help clean different types of dirt and other waste, as well as help you clean hard-to-reach places throughout your house or apartment.” NOTE: If the vacuum is not going to be used for more than 2 months, fully charge before disconnecting the power adapter and store it in a cool and dry place. The manufacturer claims that this cordless vacuum has a battery life of up to 40 minutes, but since it automatically adjusts suction power based on the floor type and mess, we found that it lasted 31 minutes in our tests. The battery is removable, so people with large spaces to clean should consider purchasing an additional battery to keep on hand. To measure noise level, we used a decibel reader with the cordless vacuum on both high and low settings and noted their findings. We also weighed each vacuum with a luggage scale attached to the handle. (By far, the lightest cordless vacuum we recommend is the Eufy HomeVac H30 Infinity, which miraculously weighs less than two pounds.)The most important factors to look at when choosing a cordless vacuum are weight, battery life, disposal system, attachments, and whether the vacuum is best for pet hair or [specific] floor types,” says Samson. The battery capacity (vacuum run time) will reduce gradually over time. In the event the vacuum runs for less than 10 minutes every time it is fully charged, it is time to replace with a new replacement battery. If the vacuum or power adaptor is damaged, please return it to the authorized service center for service or replacement to avoid personal injury. During our tests, we did find that we frequently had to lift the vacuum and place it directly on the mess to prevent it from just pushing the debris around. Our tester also had to empty the dustbin several times during the testing process, and they found it quite difficult to do so. It’s also worth noting that hair got tangled in the brushroll quite easily, and since it’s not removable, you’d have to use your fingers or scissors to cut the hair out. For this reason, pet owners should probably look elsewhere.
