- Are Cordless Vacuums Worth Buying?
It's almost a given that vacuums offer better suction and clearing of dirt compared to sweeping the floor.
This is the biggest reason why today, with the speed of dust accumulating quite fast from external factors, a vacuum should be present at home. They are just great for clearing the likes of fine hair, sucking dirt from rugs, and is also a fast solution to cleaning the floor in general.
The next question you may be wondering is why a cordless vacuum and not a regular one.
One easy reason is that they are much easier to start up and clean with right away. Cordless vacuums today generally have a charging dock for storage after every use and do not tether you to a wall when in use. Moreover, they are obviously much lighter to handle (though several notable models can be heavy too after a while).
TLDR: For daily maintenance or light cleaning, they are very handy as you don't need to keep them tethered to a wall, allowing you to quickly clean up anywhere and anytime at home.
- How to Buy a Cordless Vacuum Cleaner?
So you're interested in getting a cordless vacuum cleaner. Congratulations! They're one of the best cleaning tools you can invest in today, especially with how busy life can be. Looking at which one to buy doesn't need to be a scary ordeal, especially when you pay attention to the key features that make up a good cordless vacuum cleaner.
Here are features that you should look at when buying a cordless vacuum cleaner.
Suction Pressure/Power (Performance):
Just like most items, performance is key to being happy with your purchase. For an indication of how powerful a vacuum is, look for this measurement - 'kPa'. It literally means ' thousand Pascal'.
Simply put, this means the amount (or how much) of negative pressure the vacuum can cause to take in dirt and such. For your reference, many vacuums have at least a suction power of 20kPa (20,000 Pa). The higher the number, the easier it is to pick up dirt and debris.
While kPa isn't the main aspect to look at, this unit is necessary if you want to clean up the likes of water and such, or heavier bigger items.
- The average vacuum suction power is 20kPa
- Means the strength of negative pressure (suction) of the vacuum
- Important for those who want to get a dry and wet vacuum
Cubic feet per meter (CFM) / Airflow:
"Measured in liters per second (l/s), cubic meters per minute (m3/min), or cubic feet per minute (ft3/m); airflow is the amount of air that flows through the vacuum at any given moment." - pickvacuumcleaner.com
Suction power isn't actually the most important aspect of how powerful a vacuum is, but how good its airflow is. The CFM unit measures how much air flows through the vacuum. It also indirectly determines the resistance to motor exhaustion (so you don't rely on raw power, but how efficient the vacuum is in cleaning up).
Say your vacuum is powerful enough to suck up liquid. But how it maintains the airflow to carry debris into the dirt storage is just as important too. You wouldn't want to risk a messy clean up now, would you? Having good airflow and suction pressure is equally important to have a vacuum that does well.
The main problem? It's almost impossible to get a vacuum that has both high suction pressure and great airflow coverage due to the fact that their way of operation cannot overtake one another (they are inversely proportional). So getting a balance of both is good enough.
- Greater/larger airflow means the higher the suction power/efficiency is
- 50 to 100 CFM is the average rating for most commercial vacuums
- Note that not all manufacturers will disclose the CFM rating
A good cordless vacuum cleaner should be able to work for at least 30- 40 minutes straight on low suction mode. As you've guessed, a high suction mode operating time will actually vary but are generally about only half of the duration (10 to 20 minutes) that you can get from low suction mode.
Some brands do offer an Eco Mode whereby depending on what you are sucking dirt out from, Eco Modes are often optimised to offer battery conservation while providing the correct amount of suction power needed. So if you can, look for a vacuum that has all 3.
We also need to add; in general, smaller vacuums correspond with shorter operation periods. But do take into consideration that the brand's technology also matters.
For example, Dyson is known for its Radial Root Cyclone™ Technology. This particular concept is capable of a powerful suction as well as acute filtration. It doesn't just clear the floor of dust properly but also ensure that none lingers in the air.
- Anything with above 40 - 50 minutes of operating time is preferable
- Look for one with multiple suction modes (Low, High and Medium/Eco Modes)
- Take into account that some brands have a special suction technology to reduce the amount of time needed to clean.
- Tips For Choosing a Cordless Vacuum Cleaner:
Now that you are clear on what to look at when buying a cordless vacuum cleaner, you'll want to list down your priorities in choosing the right vacuum for you. Here's how:
Battery life requirement
As mentioned before, smaller vacuums correspond with shorter operation periods. But depending on brands, some vacuums do operate fast because of the brand's proprietary suction technology.
Many people fail to realise that with the lack of built-in filters, dust particles may escape from the vacuum. If this happens, it’ll make no difference the whole room will be covered with microparticles again after cleaning. Thus, it's best to look for one that has a HEPA filter. It's especially helpful for those who suffer from bad allergies.
Weight and mobility
Cordless or stick vacuum cleaners are preferable as they are usually ergonomically designed, making it easy to reach tight spots around your house. Plus, you won’t need to worry about a cord tailing after you and tripping over it!
- Best Cordless Vacuum Brands in Malaysia
Cleaning is one of the most time-consuming activities at home, especially if you have a large house.
Thankfully, cleaning your house is now less exhausting and much faster with the advent of the vacuum cleaner, similar to how washing machines speed up the washing process. You enjoy the convenience of moving around comfortably as if you were using a broom without the inconvenience of stepping over wires.
Malaysia has some of the best cordless vacuums available for all to buy. There are several brands in the market that keep up the quality and life span of cordless vacuum cleaners. We’ve researched and found that the most popular brands for a cordless vacuum cleaner would be Dyson, Corvan and Tineco.
Dyson was the brand that created the world's first bagless vacuum cleaner after five years and 5127 prototypes. They are well-known for their technological innovation, which ranges from beauty products to household appliances.
Due to their innovations, Dyson machines quickly became popular and are currently available in 65 countries across the world, with over 1000 engineers working for them. Their most popular product lines include their hair care and vacuum cleaners equipment such as the Dyson Airwrap Styler and the V11 cordless vacuum cleaner.
Vast of their products and services have received positive reviews from customers. Their ratings have always been perfect, with never fewer than 5 stars in almost all of their product reviews. The majority of consumers have stated that they have had positive experiences with their vacuum cleaners.
Corvan was founded in Malaysia in 2014, with the goal of improving modern life by incorporating cutting-edge technology into daily household appliances such as robot vacuum cleaners, robotic mop, and more.
The primary component of their R&D is direct communication with and listening to their consumers in order to understand a user’s requirements and expectations. They feel that this continuous approach considerably aids in generating and delivering superior value for everyone through high-quality products.
Corvan is also lucky to have a global network of strong technology partners and suppliers to make this happen. The brand is now well-known for providing value to customers through high-quality goods and excellent after-sales service.
Not a stranger to the scene; Tineco is a premium brand in smart electrical appliances and a technological innovation firm focusing on intelligent technologies. They were notable for releasing the first smart vacuum cleaner on March 13, 2019, becoming the category's pioneer.
Tineco was founded in 1998 with the development of its first vacuum cleaner and has since gained hundreds of local and international patents as well as remarkable global sales.
The stance by the majority is that Tineco vacuum cleaners clean better and leave behind less mess than other vacuum cleaners. It also has a more advanced cleaning roller that can vacuum and mop at the same time while avoiding any strain with coarser dirt.
Tineco vacuums are ideal and preferred for everyday use/light mopping as well as cleaning up huge spills. If you're searching for a low-cost option that can handle both light vacuuming and mopping, consider the Tineco iFloor, which may be one of the finest for the money.
- Best Times to Buy a Cordless Vacuum Cleaner
One might not think much about a vacuum cleaner until it's time to replace it. Today's models are more effective, with genuinely impressive cleaning power. We propose that, as with other appliances and electric equipment, you do some research and shop at the right time to obtain the greatest value.
Aside from determining which sort of vacuum cleaner best meets your needs, conducting research on various models, and settling on a budget, you need also to know when to get one. When you buy can influence how much you pay and the choices available. So, when is the ideal time to purchase a vacuum cleaner?
The best time to purchase a cordless vacuum cleaner in Malaysia would undoubtedly be during monthly or festive season deals. Sales like “Chinese New Year, Hari Raya, Deepavali” are great times as the discounts and offers are insane. Some brands will also give limited edition gifts that tie with the festive season too.
Purchasing cordless vacuum cleaners just in time or before the festive season is the best thing to do since it helps keep your home clean over the holidays. Plus, brands also throw in additional gifts to offer you a “quick easy cleaning” experience.
Monthly & annual sales:
Aside from festive seasons, acquiring a cordless vacuum cleaner during sales like 11.11 or Black Friday as well as Lazada and Shopee's birthday sales is perfect. It is because the discounts are the greatest compared to other events and sale durations.
Watch out especially for 11.11 or just any Year-end sale, as many brands do clearance sales to make way for new models.
With Christmas sales happening too, the Year-end sales are one of the biggest shopping seasons in Malaysia, with many discounted coupons and promo codes released to be used on top of the already discounted prices.
- Cordless vs Corded Vacuum Cleaners
Dynamic components and a variety of equipment are included with corded vacuums, making cleaning a breeze. The effective components can reach all of the surface's corners.
There are many pros and cons to having either a cordless vacuum or a corded vacuum. The former is a rather new type of invention from the latter. What’s appealing about the cordless variant is that they just seem easy to access and use right away. Whereas, the corded variant is just useful for most houses and is much cheaper.
So, how do you choose between the two? Here, we help you break down both briefly.
Corded vacuum cleaners - Powerful, heavy-duty:
A corded vacuum cleaner comes to mind whenever you think about vacuum cleaners. They come with a plug-in connection and many attachments to aid in thorough cleaning. Therefore, you must plug it into a power source before using it. That is the primary reason behind the name.
As these machines are usually bigger, they allow for the inclusion of a stronger motor to help you do heavy-duty cleaning. And because they are also usually bigger, corded vacuums have a big dust collection area. As a result, you may use your cleaner for longer periods of time without having to dispose of the dust it collects.
Because of a bigger motor for bigger suction power, corded vacuums have to connect to your home's power supply. This also causes many to believe that conventional versions are the finest choice for carpeted flooring.
Although bulkier, corded vacuums have improved thanks to advancements in technology. Therefore, if with several locations to clean in a big area, a corded vacuum cleaner would be ideal since it can run for an extended period of time if the power source is dependable.
Cordless vacuum cleaners - Lightweight, ‘Clean everywhere’:
While suction power is typically more reliable on the corded variant via a wall power supply, cordless vacuums with lithium-powered batteries are just as reliable. In fact, suction power on cordless vacuums tends to be almost equal to corded variants than cordless vacuums with non-lithium batteries.
A cordless vacuum cleaner, as opposed to a corded vacuum cleaner, does not have a power connection cable. They equip a rechargeable battery that has to be charged every now and then. As the majority of the battery-type used are lithium, you'll have enough juice to last you for a couple of cleaning sessions. Disposable batteries, as opposed to permanent batteries, are simple to charge and replace.
Also, because it is readily moveable from one area to another, a cordless cleaner allows you to get into tight spots without being tethered to the wall. And because it is cordless, you have complete freedom of movement in cleaning angles. The lightweight design is ideal for cleaning around furniture and in tight places.
Obviously, the suction power of a cordless vacuum is generated by the battery. As a result, as a battery begins to drain and diminish, suction strength decreases. So for a seamless cleaning experience, constant charging is required.
Tip - To minimise the chances of forgetting to charge the vacuum, look for those with a charging station dock & a lithium battery for extended durability.
- How long should a good vacuum last?
The vacuum cleaner has been around for a few decades, and there are many reasons why it's still the best-selling house-cleaning device.
Notably, it makes the entire house cleaning process much more efficient. A clean house is always a desirable feat for homeowners in this fast-paced world, and vacuum cleaners are just the one tool that fits into this category well.
Unlike mopping, which requires more time and energy, all you have to do is walk over an area with a vacuum and it will suck up any dust or residue. Given that thought, those from more reputable vacuum brands may attain speeds of up to 25,000 spins per minute, so you should be able to clean your entire house in as little as an hour.
Average lifespan - 8 years:
Aside from the fact that it performs well, buying a high-quality model will provide you with years of heavy service due to the quality of mechanism accessories that are used.
Of course, this is dependent on the brand and the price that you pay, which leads us to the subject of how long vacuums last and if there is anything you can do to extend their lifespan.
There are several aspects that may be considered to maintain a good lifespan for your cordless vacuum cleaner to last longer. In general, cordless vacuum cleaners have an average lifespan of 8-10 years, however, this varies depending on the brand. Keeping your vacuum cleaner on a regular basis is a huge bonus for longer-lasting vacuums. In fact, there are cases where vacuums are kept beyond 10 years up to 20 years!
Therefore, do consider purchasing a vacuum cleaner from a niche brand like Dyson or Corvan as they are fully focused on the few product lines that they have. They are a terrific long-term investment that allows you to receive a flexible vacuum cleaner at a fair and reasonable price.
Also, bear in mind that appropriate vacuum cleaner maintenance is essential for prolonging the vacuum's lifespan and keeping the device functioning at its peak performance.
Tips for longer cordless vacuum life:
- Avoid filling the bag or bin to the brim, since this may cause the unit to clog.
- Keep in mind to clean or replace the filter anytime it becomes filthy.
- Clearing the motorized brush of matted hair, thread, and other fibres that can strain the motor every few weeks.
- Constantly checking the hose for clogs on a regular basis.
- What floor can a cordless vacuum clean?
The quick answer: A distinctive vacuum cleaner is recommended for different kinds of flooring. So choose a vacuum for the general “hardness” of your floor.
When purchasing a vacuum cleaner, keep these pointers in mind.
- If you have hard flooring in your home, such as hardwood, tiles, or laminate, a vacuum cleaner with many attachments is your best bet. A cordless vacuum cleaner is perfect to avoid damaging your floor as you can easily adjust the suction power.
- It’s different for carpets; you'll actually need something very strong for the carpet as the fibres are more persistent in trapping dust. Therefore, the vacuum’s motor must be capable of extracting dust and dirt from carpet fibres. If you don’t want to worry about damaging your floors, an upright cordless vacuum cleaner is a great choice.
- Prepping Your Vacuum for Cleaning
To avoid mishaps with your appliance, always remember to prepare your vacuum cleaner for use. The suction of your vacuum cleaner can be diminished by dirt and debris. Hence it is important to do routine maintenance on your vacuum cleaner after each use.
Before you start, at the very least, make sure the dirt bin is empty. Alternatively, if your vacuum cleaner utilises bags, ensure sure the bag is just half filled. Then check to see if the roller brush or beater bar spins freely. Remove any entangled string, hair, or other waste from the brush.
Also, remember to always use the attachments provided alongside your vacuum cleaner. Even the most powerful vacuum cleaner head will not be able to remove all of the debris from the area where the floor meets the walls. Not being careful with your cleaning will result in black margins on carpets or a gritty grey line if you have hard flooring.
Cleaning carpet floors:
To vacuum carpeted floors, make it a habit to use the roller brush, which removes fibres and allows the suction of the machine to remove impurities.
Keep in mind that deep-down dirt will not be cleaned if the brush head is set too high. When it is too low, it cannot spin properly and can meddle with the suction of the machine.
Cleaning hard floors:
For those with hard floors, you should use a machine with a felt or fabric roller or a flat floor head that does not have a rotating brush. These specialist hard floor vacuum attachments are more effective at collecting dust and tiny particles from hard surfaces. Unlike the carpet attachment, they will not harm the surface of your hard floor.
Doing quick cleans:
In terms of quickly cleaning floors, there's nothing wrong with rapidly vacuuming with a powerful motor. However, this type of rapid cleaning should not be done on a regular basis. Prepare your vacuum, clear furniture from the area you'll be vacuuming, and then take your time cleaning it well to remove filth and dust off your floors and out of your home.
- How To Clean A Vacuum Cleaner Properly?
It's interesting that your vacuum cleaner is typically the dirtiest appliance in your household. By the time you've finished cleaning, you might not be eager to provide your vacuum cleaner any love and care. But a clean, well-maintained vacuum cleaner will perform a better job of cleaning up dirt around your house and will last longer.
Read the directions for your specific model before performing any maintenance on your vacuum cleaner. These will teach you how to secure and change the filters, as well as which parts are safe to wash.
What is needed to clean cordless vacuum cleaners are generally found in your home.
- Dish Soap
- Microfiber Cloth
- Garbage bag
It is advisable to clean the blockages that are formed in the vacuum cleaner as the most common cause of a vacuum cleaner's loss of suction is clogs, which slows and overheats the unit. To avoid such issues, ensure that the dust canister is completely emptied after each use. Check the hose and machine entry for any dirt or dust that may cause a blockage in order to reduce or eliminate obstructions from the tubes.
Many vacuum cleaners have washable filters, making it simple to clean them without the help of a professional.
- To simply remove dust from the filters, remove and tap them against a hard surface. If you want to limit the spread of dust and pollutants into your house, perform this step outdoors.
- Using lukewarm water, wash the washable filter and allow it to dry for at least 24 hours. If the filters aren't washable, simply tap them against a hard surface to remove access dirt.
We’re sure that you’ve probably seen out-of-shape vacuum head brushes. As a result of frequent use, the vacuum cleaner brush may appear worn out. This is due to pushing the brush head against the floor constantly. Not only that but threads and hair from the floor may have constantly gotten stuck and trapped in the brush.
If that happens, don't pull the threads or hair. Instead, cut any threads or hair that may be clogging the brush. Avoid cutting the bristles at all costs.
In short; clean your vacuum cleaner on a regular basis and it will last longer. If you often use a vacuum cleaner, make sure to clean it every three months. Regular cleaning ensures that the vacuum cleaner eliminates impurities and dust efficiently while also reducing the amount of time you have to vacuum your home.
- Bag vs Bagless Vacuums
One of the most recent categories for vacuum cleaners is bag or bagless. Is a bagless model preferable to one that requires vacuum cleaner bags? It is entirely dependent on your family and its necessities.
Bagged Vacuum Cleaners:
In short, a bagged vacuum cleaner operates in the usual manner, with the changeable bag acting as a filter to capture dirt while enabling air to travel through the bag.
When the bags are full, they must be changed. Filters in bagless vacuum cleaners capture dirt and dust in a dirt cup or chamber, which may then be emptied.
So what happens when the bags get worn out? They require replacements once it becomes full. Replacing the bag isn't a big deal, and most vacuum cleaner bags aren't expensive. However, having to remember to check if the bag is full may be annoying.
Luckily, some bagged vacuums feature an indicator light that indicates when the bag needs to be replaced. Vacuum cleaner bags also means less interaction with the dust and particles contained within the bag. Just remove the old bag and discard it, voila!
Pros of a bagged vacuum:
- Bagged vacuum cleaners are less messy. There is no possibility for the dust to end up on the floor or in your face.
- It's preferable for allergy problems. Bags keep dust and allergens completely isolated from the person vacuuming. As a result, dust disposal is considerably less likely to trigger an allergic reaction.
- Fewer maintenance costs are required. Vacuum cleaner bags reduces a compressive load on your vacuum cleaner for a variety of reasons. As filters are incorporated into the bags themselves, they do not need to be cleaned. Also, the bags have ample storage than their bagless equivalents, so you don't have to discard dirt as frequently.
Cons of a bagged vacuum :
- Eco-unfriendly. While the majority of vacuum cleaner bags are composed of paper, they may also include other elements and hence are not 100% recyclable.
- Vacuum cleaner bags are rather expensive and must be replaced regularly, which can put a dent in your wallet.
Bagless Vacuum Cleaners:
There's very little chance of forgetting to empty the vacuum cleaner with a bagless vacuum cleaner since the dirt and debris in the cup can be seen clearly.
Many versions, however, include filters that still has to be brushed, rinsed and dried entirely, or totally changed. Depending on your vacuum cleaner, emptying the dirt cup might be an unpleasant operation.
Moreover, without a bag, dust may frequently swirl back out of the cup, and you may need to shake or scrape accumulated dirt from the container's bottom. However, if you vacuumed up anything you need to recover, it can be readily recovered from the dirt cup.
Pros of a bagless vacuum:
- Bagless vacuums are eco-friendly. They contain recyclable filters and, of course, no bags that end up in non-recyclable residual waste.
- These vacuums are known to be less costly in the long run as there’s no need to buy or spend on bags for your vacuum.
Cons of a bagless vacuum:
- They can be messy to clean as it requires you to get your hands dirty whilst cleaning the dirt cup.
- Bagless vacuums have cups that require washing and drying for maintenance compared to just throwing out a bag. Worse, you'll probably have to wipe out the cup more frequently than you would a bag.
- How To Optimize the Battery life on Cordless Vacuums
Where there is no local electrical supply, a cordless vacuum can be of great assistance in cleaning up spills or for just about anything. Utilizing the battery life of these cleaners is a real treat, but it is not as easy as it may appear to be.
- If your vacuum is powered by conventional batteries that are not rechargeable, the only justifiable approach to guarantee a longer lifespan is to ensure that you avoid vacuums going into the 'standby' feature. Switching the vacuum within on or off is good enough.
- For cordless vacuums with rechargeable batteries, they are designed in such a way that you need to have a place to store the battery charger somewhere. As such, a vacuum with a charging dock is convenient and ideal as it guarantees that the cells are always filled.
- Finally, keep your vacuums in a cool area to avoid power failure to the batteries.
Some rechargeable batteries, particularly high-demanding batteries, have a liquid core and must be completely depleted before being recharged. With irregular charging patterns, it can mess up your vacuum’s recall to allow the full charge (think: the bad charging habits for a smartphone).
Although they are no longer widely used, these batteries may tend to only recall and allow the amount of charge they previously had.
If you recharge such a battery after it has been only one-quarter discharged, you will discover that it will only accept one-quarter of the available charge in the future, even if it has been totally exhausted. So, for optimal charging, ensure that you read your vacuum’s manual to know the best way to charge it.
