Choosing a cordless vacuum is a significant decision, as it’s a device you’ll rely on for years. The right model can make cleaning a pleasure, while the wrong one can be a constant source of frustration. In this review, I tested 15 leading cordless vacuum cleaners from various manufacturers and price points, subjecting each to the same rigorous cleaning tests to determine which ones truly excel.
My testing involved weighing out spillages of flour, recycled wood cat litter pellets, and pet hair, then measuring how much each vacuum collected in a single push-forward and pull-backwards motion. I also tested battery life at full suction and in economy mode, and measured suction pressure using a gauge. The overall winner was the Shark PowerDetect Clean & Empty IP3251, while the Dyson V15 Detect Absolute took the top spot for deep cleaning.
Cordless vacuums offer unmatched convenience, with no cables to unwind or sockets to find. However, battery life can vary significantly, from over an hour on low settings to just minutes on full power. Most models should last long enough for an average-sized home, but larger spaces may require a mid-clean charge or an extra battery.
Suction power is important, but a well-designed floor head can help a less powerful vacuum outperform a more powerful rival. I measured suction in kilopascals (kPa); 25kPa or above is good, while below 10kPa may struggle with larger debris. Weight is also key, as you’ll be carrying the vacuum around the house. Models under 3kg are relatively light, but heavier units may offer more features or larger dust bins.
All vacuums tested are being returned to manufacturers or donated to the British Heart Foundation. For a full breakdown of the top performers and detailed test results, read on.
