A cordless revolution

13 January 2025

Taking the time to carefully consider the technology included within vacuum cleaners can reap a number of benefits to operators – from increased on-site productivity and efficiency, through to reduced vacuum maintenance. Kevin Brannigan outlines some of the key features to look for when selecting your kit. 

BATTERY POWERED cordless vacuums are an ideal choice as there is no power lead restricting the users ability to work in any location. Operators do not need to worry about the location of power sources, the safe placement of cables around the work area, or the risk of associated trip hazards, making them ideal for working in restricted spaces, or for applications such as cleaning stairwells where cables can be a concern. In addition, cordless vacuums are often quieter making this technology ideal for working in occupied spaces, as well as helping to protect the user from the negative effects of prolonged or frequent exposure to noise. 

Due to advances in battery technology and innovative vacuum design from leading manufacturers, professionals can experience the high performance suction, reliability and power they would expect from corded machines, with these added benefits of increased flexibility and safety. Better still, today’s cordless models are powered using lithium-ion batteries that hold and store high levels of energy for long periods of time, enabling users to work without having to ‘down tools’ to frequently change, or recharge batteries.

When investing into a cordless vacuum, consider whether the battery charging process has been optimised. For instance, Makita has designed its batteries to communicate with theirintelligent chargers and this allows the charger to identify any issues with the battery such as over discharge or overheating. The charger will then work to rectify any issues (for example, by cooling the battery down before charging commences) to ensure no damage is caused to the battery – and make the charging process faster and more efficient. 

As a result of this process, Makita’s 18V LXT lithium-ion batteries can be charged in as little as 22minutes (for 3.0Ah batteries) up to 55minutes (for 6.0Ah batteries). In addition, a 2.5Ah XGT 40VMax battery will charge in just 28 minutes and a 4.0Ah battery in just 45 minutes.

Brushless motor design 

Another key feature that contractors should look for is the type of motor included within the vacuum cleaner. Although brushed motors are effective, the friction caused by the contact between the brushes and commutator within the motor can result in wear and tear – and the need to regularly replace the internal brushes. 

To avoid this, choose a vacuum that includes a brushless motor. Brushless motors work using an on-board electric circuit which sends electronic currents towards the stator coils. When the stator coils receive the electric currents, they are driven electromagnetically and the position of the north and south poles within the motor changes. This pulls or resists the rotor’s magnet and makes the rotor rotate continuously. 

The omission of brushes means that no friction is created, reducing wear and tear. No friction also means that no energy is lost through heat production, keeping the vacuum working for longer, requiring less maintenance and improving efficiency on-site as there are no concerns over the machine overheating. 

Ability to switch between applications

Selecting a solution that shares the same operating battery system with other cordless equipment means the same battery can be used to power different types of vacuum – enabling users to effortlessly switch between vacuums for different tasks when required. For example, Makita’s 18V LXT batteries can be used to power backpack cleaners, upright models, stick, tub and robot vacuums. The same battery can also be used across Makita’s broader product portfolio, including its outdoors and grounds maintenance solutions which encompasses blowers, power washers and sweepers, making a shared battery platformideal for those working with a wider remit.  

As an additional advantage, this approach allows new vacuums to be purchased more cost effectively as it allows contractors who already have the batteries to take advantage of ‘body-only’ options.

Increased capture rates

Consider the capacity volumes of the vacuum, as this will have an impact on the amount of time spent emptying the canister or dust bag, even for compact models. For example, Makita’s cyclone attachments, which are compatible with Makita’s cordless stick vacuum range, help to increase the longevity of the filter and motor, meaning operators don’t need to empty the cannister or dust bag as often, maximising productivity and the lifespan of the vacuum.
