Corded vs Cordless Vacuum Cleaners

Corded vs. cordless is often the big question when researching a new vacuum cleaner but for many homes one vacuum cleaner often isn’t enough. Quick clean-ups, deep cleans, and everything in between demand versatility, which is why there is often the requirement for a cordless and corded vacuum cleaner. Below, our Product Training Lead, Sophie Lane shares expert advice on what to consider when choosing a vacuum cleaner and the advantages of both types.

Buying Considerations When Choosing a Vacuum Cleaner

Suction Power
Suction power can vary significantly between models, but the maximum power typically found today is around 900W, due to EU regulations. A vacuum cleaner which offers adjustable suction power is a fantastic feature, as different surfaces require different levels of suction. For instance, delicate fabrics such as curtains and upholstery would benefit from a lower suction power to avoid damage.

Dust Capacity
The appropriate dust capacity for a vacuum cleaner depends on factors like lifestyle, location, and pets. If a household frequently engages in outdoor activities or someone has a job that brings in extra dust and debris, a larger dust capacity may be required. Pets, especially those with longer fur, also contribute to the amount of dust and debris in the home. Additionally, if living in a rural area, more dirt may come inside, making a larger dust capacity more beneficial.

Filtration – HEPA vs non-HEPA
Whether corded or cordless, filtration matters. Many Miele vacuums feature HEPA AirClean filters that capture 99.999% of fine dust and allergens – perfect for allergy sufferers. Some models also include Active AirClean filters with charcoal layers to neutralise pet odours.

Cord Length and Total Reach
The length of the cord and total reach (from plug to floorhead) is an important consideration, especially when there is a large area to clean. A longer reach means there’s no need to unplug and move the vacuum as often, which is particularly useful for larger spaces. The cord length is especially crucial if there’s not a nearby power outlet. Miele corded vacuum cleaners benefit from a large 12m operating radius, which enables effortless cleaning of large areas without interruption.

Battery Life and Runtime
When choosing a cordless vacuum, it’s important to consider how long it can run on a single charge – especially for larger homes. The Miele Duoflex HX1 offers up to 55 minutes of runtime, which is ideal for everyday cleaning tasks. For those who need extended cleaning time, the Miele Triflex HX2 Pro is a great option - it features a swappable battery system, allowing you to double your runtime with an additional battery pack for uninterrupted cleaning.

Advantages of a Corded Vacuum Cleaner

Unlimited Runtime
Corded vacuum cleaners offer continuous cleaning without the need for charging, making them ideal for larger homes or those with high cleaning demands. Unlike cordless models, which can experience a decline in battery capacity over time, requiring shorter cleaning durations and eventual battery replacement, corded designs don’t have this issue.

Dust Capacity
Corded vacuums typically have larger dust capacities, meaning they need to be emptied less frequently.

Durability
Corded vacuums like the Miele Guard M1 Cat & Dog are designed for long-term reliability and high-performance cleaning. With robust motors and generously sized dust bags, they’re ideal for deep cleaning sessions and larger homes where consistent suction and extended use are essential.

One of the key advantages of corded models is unlimited runtime - there’s no need to worry about battery life or charging interruptions. This makes them perfect for thorough cleans across multiple rooms or entire floors in one go. Combined with Miele’s self-sealing dust bags, which lock in dirt and allergens during disposal, the Guard M1 offers a hygienic and hassle-free cleaning experience. It’s a dependable choice for households that need powerful, uninterrupted cleaning with minimal maintenance.

Advantages of a Cordless Vacuum Cleaner

Storage and Charging
Cordless models often come with wall-mounted charging stations or compact docking solutions, making them easy to store and always ready to use. This is especially helpful in homes with limited storage space.

Cleaning Flexibility and Convenience
Cordless vacuums offer unmatched flexibility, especially for quick clean-ups or reaching tight spaces. They’re ideal for multi-level homes or for users who want lightweight, grab-and-go cleaning. Miele’s Duoflex HX1 is a great example - it’s compact, powerful, and converts easily into a handheld unit for stairs, upholstery, or car interiors.
