The market for cordless vacuum cleaners is extensive, and the technical specifications can seem overwhelming at first glance. A cordless vacuum cleaner offers flexibility and convenience, but its performance depends on clearly definable parameters. This guide focuses on the objective criteria relevant for making an informed purchasing decision: suction power, battery performance, filtration systems, and application-specific features.

Technical Selection Criteria for a Cordless Vacuum Cleaner

The performance of a battery-powered vacuum cleaner can be evaluated based on several technical metrics. These help you find a model that meets the specific needs of your household.

Suction Power (Motor Power and Pascal Ratings)

Cleaning performance is primarily determined by suction power. This is often specified in watts (W) for motor power and in Pascals (Pa) or kilopascals (kPa) for the negative pressure it generates.

• Motor Power (Watts): A brushless motor is often an indicator of higher efficiency and longevity. Power ratings of 400 W or more suggest strong suction power, suitable for carpets and picking up pet hair.
• Suction Pressure (Pascals): The Pascal rating describes the negative pressure the device can generate. Values from 20,000 Pa (20 kPa) are considered solid for hard floors. For households with carpets or pets, models with 30 kPa or more are a worthwhile option for removing deep-seated dirt.

Battery Runtime and Charging Concept

A long battery runtime is crucial for the uninterrupted cleaning of larger areas.

• Runtime: Manufacturer specifications usually refer to Eco mode. The realistic usage time in Standard or Turbo mode is often shorter. Runtimes of 50 to 70 minutes in Eco mode are a good benchmark for cleaning an entire house.
• Swappable Battery: Models with a removable battery offer the advantage of doubling the runtime with a second battery. The battery can also be charged separately.

Filtration Systems: HEPA and Cyclone Technology

An efficient filtration system is particularly important for allergy sufferers and households with pets.

• HEPA Filter: A "High-Efficiency Particulate Air" filter can, by standard, filter up to 99.97% of particles as small as 0.3 micrometres from the air. This includes pollen, fine dust, and dust mite droppings. Washable or replaceable HEPA filters contribute to better air hygiene.
• Cyclone Technology: Multi-cyclone systems use centrifugal forces to separate dust and dirt from the air before it reaches the main filter. This prevents the filter from clogging quickly and ensures more consistent suction power.

Weight, Handling, and Accessories

A lightweight and ergonomic stick vacuum makes it easier to clean stairs, ceilings, and hard-to-reach areas.

• Weight: A device weight of under 3.5 kg is considered easy to handle.
• Floorhead: A motorised brush roll with an anti-tangle feature is advantageous for picking up hair. LED lights on the nozzle make dust visible in dark corners.
• Accessories: Crevice tools, upholstery brushes, and flexible hoses significantly expand the device's range of applications.

Frequently Asked Questions (FAQ)

1. How many Pascals (Pa) should a good cordless vacuum have? For everyday cleaning of hard floors, values around 15,000 Pa (15 kPa) are often sufficient. For households with carpets, upholstered furniture, or pets, a suction power of at least 25,000 Pa (25 kPa) is recommended to effectively remove deep-seated dirt and hair. Models with over 30 kPa offer very high cleaning performance.

2. Are cordless vacuums suitable for pet hair? Yes, many modern cordless vacuums are very well-suited for pet hair. The key factors are high suction power (ideally over 25 kPa) and a motorised brush roll, preferably with anti-tangle technology that prevents long hair from wrapping around it. A good HEPA filtration system is also beneficial for filtering pet allergens from the air.

3. What is the advantage of a bagless vacuum cleaner? The main advantage of a bagless system is the lower running costs, as there is no need to purchase replacement dust bags. The dustbin can be easily emptied over a bin at the touch of a button. This is not only cost-effective but also more environmentally friendly. Furthermore, with many bagless models featuring cyclone technology, the suction power remains more consistent even as the bin fills up.
