One of the most notable features of the Shark BU3521UK is its cordless design, providing up to 40 minutes of uninterrupted cleaning time on a single charge. This eliminates the hassle of constantly plugging and unplugging as you move from room to room, giving you the freedom to clean large areas without any restrictions. With a 4.5-hour charge time, it’s ready to go whenever you need it.
The vacuum’s powerful suction, driven by 240w Hypervelocity Accelerated Suction Power, ensures deep cleaning across various surfaces. Whether you're dealing with carpets, hard floors, or upholstery, the Shark BU3521UK delivers consistent performance. The main head is equipped with the PowerFin Floor Nozzle, designed to tackle different floor types effectively. It also features dedicated settings for carpets and hard floors, ensuring optimal results no matter the surface.
Pet owners will appreciate the vacuum's specialised pet hair cleaning capabilities. The Anti Hair Wrap Technology prevents hair from tangling around the brush roll, making it easier to maintain and ensuring that the vacuum continues to perform at its best. Additionally, the Anti-Allergen Complete Seal captures dust and allergens, making it an ideal choice for households with allergy sufferers.
The vacuum’s bagless design and 0.7L bin capacity make it easy to empty, and with the Clean & Empty Auto-Empty System, it can hold up to 30 days of dirt and debris before needing to be emptied. This feature significantly reduces the frequency of maintenance, allowing you to focus more on cleaning and less on upkeep.
Weighing only 2.7 kg, the Shark BU3521UK is lightweight and easy to manoeuvre, making it suitable for cleaning both large spaces and tight corners. Its detachable base allows it to transform into a handheld vacuum, providing additional flexibility for cleaning stairs, upholstery, and even car interiors. This versatility is further enhanced by the included accessories, such as the crevice tool and upholstery brush, which help you tackle those hard-to-reach areas with ease.
The vacuum operates at a noise level of 84 dB, and while it’s not the quietest on the market, it does offer a Quiet Mode for more subdued operation when needed. The absence of an internet connection or smart features keeps it straightforward and user-friendly, focusing purely on delivering exceptional cleaning performance.
The Shark BU3521UK Clean & Empty Cordless Upright Vacuum Cleaner, with its powerful suction, versatility, and innovative features, is a reliable choice for anyone looking to keep their home spotless with minimal effort. Whether dealing with everyday dust and dirt, pet hair, or allergens, this vacuum is well-equipped to handle it all, making it a valuable addition to any household.
