While cordless vacuum cleaners may seem to be the most high-tech option, a new study by Which? has found that corded are still the most effective.
More than a third of the cordless models tested by the consumer magazine were found to be so bad they were ranked as "Don't Buys".
On average, the corded models clean better on all floor surfaces than cordless ones.
The magazine found that average dust pick up on carpet for corded is 70 per cent compared to just 41 per cent for cordless.
Cordless vacuums are also more likely to be expensive; the average cost of a Best Buy corded model is £240, compared to £300 for a Best Buy cordless. One of the Don't Buy cordless models cost more than £400.
The magazine has also found that the best corded models are more likely to last longer than other options.
Based on their customer survey, 93 per cent of vacuum cleaners from the most reliable corded vacuum brand were still working without problems after three years. This was only found at 85pc for the best cordless vacuum brand.
After seven years, 90per cent of models from the top corded brand were still fault-free.
Despite this, nearly half of Which? members surveyed in January 2019 said they were considering a cordless vacuum for the next time they buy one.
Harry Rose, Editor of Which? Magazine, said: “We’ve spent countless hours putting both corded and cordless vacuums through their paces, and our years of expert testing have shown that you may you may actually be better off with a corded model, despite what changing trends in the market might suggest.
“If you’re looking to buy a new vacuum, don’t assume that price is any indicator of quality, or that just because manufacturers are favouring cordless models means you should be too. Whether you’re looking for convenience, reliability or cost-effectiveness, our independent testing can help you find the model that’s right for you.”
