With its lightweight aluminium wand which attaches directly to the machine the Dyson Digital Slim converts from a handheld to a slim vacuum cleaner. It has anti-static carbon fibre brushes to improve fine dust pick-up from hard floors. Static on hard floors is generated when brush bars spin at high speed – fine dust becomes attracted to floors making it difficult to suck up. The Dyson Digital Slim’s brushes reduce the build up of static charges for improved fine dust pick up. The brush bar also has stiff nylon brushes to pick up ground-in dirt from carpets.
A key benefit is the product's digital motor. "Our digital motor is small, light and power efficient, with an impeller that spins at 104,000 rpm – more than three times faster than a traditional motor," says James Dyson. Dyson’s digital motors are the fastest, highest power density motors ever developed for domestic appliances. The Dyson digital motor is small, light and energy efficient and it is self-regulating to optimise efficiency. An internal microprocessor makes up to 3,300 adjustments each second to control its speed to monitor and self-adapt to vacuum airflow.
Other cordless vacuums can lose up to half their suction power in use; the Dyson Digital Slim runs for up to fifteen minutes of constant suction. It can be recharged in the docking station or remotely by removing the battery from the machine. Once the machine is fully charged it no longer draws electricity, helping achieve Energy Star Rating. Using only a 22.2V lithium-ion battery pack, the machine releases its charge evenly so there is no drop in performance. It takes just 3.5 hours to fully charge the machine, up to three times faster than other cordless vacuums. A full charge gives up to 15 minutes of power, depending on cleaning mode.
Dyson Digital Slim costs $499 and is available from leading electrical retailers.
