Choose a Cordless Vacuum Cleaner Guide

The search for a new vacuum cleaner leads many to ask: is a cordless vacuum the right choice? The flexibility to manoeuvre through multiple rooms or over stairs without a cord is a clear advantage. However, the selection of models is vast, and the technical specifications can be overwhelming. This guide will help you understand the key features of a cordless vacuum cleaner and make an informed decision that suits your household—whether you're dealing with pet hair, allergies, or large spaces.

What to Look for When Buying a Cordless Vacuum Cleaner

To find the right device, it's helpful to understand a few core technical features. These three points are crucial for performance and user convenience.

1. Suction Power: Understanding kPa and Air Watts (AW)

The cleaning performance of a cordless vacuum is often specified in kilopascals (kPa) or Air Watts (AW).

• Kilopascals (kPa) measure the vacuum pressure generated by the motor. A higher kPa value indicates a stronger ability to pull dirt and dust from carpets and crevices.
• Air Watts (AW) is a more comprehensive unit of measurement that considers both airflow and vacuum pressure. It provides a more accurate indication of the actual cleaning efficiency at the nozzle.

For households with carpets or pets, a cordless vacuum with strong suction power (e.g., over 25 kPa or 150 AW) is recommended to reliably remove deep-seated dirt and hair.

2. Battery Life and Home Size

A crucial factor is a cordless vacuum's long battery life. Consider the size of the area you need to clean. For a flat up to 80 m?, a runtime of 40 minutes may be sufficient. For larger houses or for particularly thorough cleaning, models with 60 minutes or more of runtime are advantageous. Also, pay attention to the charging time and whether the battery is swappable, which can extend the device's lifespan.

3. Filter Technology and Accessories

For allergy sufferers or households with pets, a vacuum cleaner with a HEPA filter is a smart choice. HEPA (High-Efficiency Particulate Air) filters can capture the smallest particles like pollen, dust mite faeces, and fine dust from the exhaust air, contributing to cleaner indoor air.

Specialised accessories increase versatility. A motorised mini-brush is ideal for removing pet hair from upholstery, while a crevice tool makes cleaning corners and edges easier. A lightweight cordless vacuum is also easier to handle, especially when cleaning stairs or high places.

Frequently Asked Questions

How much suction power does a good cordless vacuum need?

For everyday cleaning of hard floors, values around 15-20 kPa or approx. 100 AW are often sufficient. For households with carpets, children, or pets, a higher power of over 25 kPa or 150 AW is recommended to effectively remove deep-seated dirt and hair.

Are cordless vacuums really suitable for pet hair?

Yes, many modern cordless vacuums are very well-suited for removing pet hair. Models with high suction power and special, motorised brush rolls with anti-tangle technology can reliably pick up hair from carpets and upholstery without it constantly getting caught in the brush.

What is the advantage of a HEPA filter in a vacuum cleaner?

A HEPA filter traps very small particles such as dust mites, pollen, mould spores, and pet dander that are not retained by conventional filters. This makes the air expelled from the vacuum cleaner cleaner. This can noticeably reduce symptoms for allergy and asthma sufferers and contributes to a healthier indoor environment.
