Shark BU3521EU Clean & Self-Empty 0.42L 21.6V Stick vacuum cleaner, Blue, White

The Shark BU3521EU is a 2-in-1 cordless vacuum that converts from a stick to a handheld configuration for different cleaning applications. It is powered by a 21.6V lithium-ion battery, which provides up to 40 minutes of runtime on a full charge. The main floor head is engineered to detect various floor types, automatically adjusting its performance for carpets and hard surfaces. In its handheld form, the vacuum addresses above-floor cleaning on furniture, stairs, and in vehicles. The complete unit has a total weight of 2.7 kg, designed for manageable handling.

This model is equipped with a self-emptying charging base that automatically evacuates the 0.42 L dustbin after each use, which reduces direct exposure to collected debris. The system uses a cyclonic dirt separation method and includes a HEPA-class filter designed to capture fine particles and allergens. For maintenance, the filter is washable. The vacuum is supplied with a set of attachments for specific tasks, including a crevice tool for narrow spaces, an upholstery nozzle, and a motorized brush for embedded dirt.
