Best Prices on Hepa Vacuum Cleaners
The Bosch Unlimited 9 represents advanced cordless cleaning technology with its revolutionary MicroClean sensor system. This intelligent vacuum detects microscopic particles invisible to the naked eye and captures over 99.9% of dust down to 0.3 microns.
The MicroClean Ring provides real-time feedback through colour changes - black indicates dirty surfaces, white shows active cleaning and blue confirms deep cleanliness. The TurboSpin motor operates at up to 70,000 rpm for exceptional suction power.
Key features include a dust compression slider that doubles capacity, reducing emptying frequency by 50%. The 3.0 Ah lithium-ion battery delivers up to 60 minutes runtime and works with over 100 Power For All Alliance tools.
The MicroClean sensor detects microscopic dirt particles that are invisible to the naked eye. It works in conjunction with the MicroClean Ring, which changes colour to indicate cleaning progress. The ring shows black when surfaces are dirty, white during active cleaning and blue when surfaces are deeply clean. This technology ensures you achieve a thorough clean beyond what traditional vacuums can detect.
The 3.0 Ah battery provides up to 60 minutes runtime in Eco mode, which is suitable for light cleaning tasks. In Auto mode, expect approximately 30-40 minutes depending on surface type and debris level. Turbo mode delivers maximum suction but reduces runtime to around 15-20 minutes. The battery charges fully in approximately 4 hours using the included quick charger.
The dust compression slider doubles the effective capacity of the 0.4-litre dust box by compacting collected debris. This reduces emptying frequency by up to 50% compared to traditional dust boxes. The system works by compressing dust and debris when you slide the mechanism, allowing you to collect more dirt before needing to empty the container. This makes cleaning large areas more efficient.
Yes, the vacuum excels at pet hair removal thanks to its RotationClean technology and powerful TurboSpin motor. The unique bristle design reduces hair tangling by 3x compared to conventional brushes. The MicroClean brush with LED lighting helps illuminate dark areas where pet hair often accumulates. The HEPA filtration system also captures pet dander and allergens effectively.
The vacuum performs excellently on hardwood floors, tiles, laminate and short-pile carpets. The MicroClean brush achieves over 99.9% dust pickup efficiency across these surfaces. However, some users report reduced effectiveness on thick, long-pile carpets where the brush may stall. The vacuum includes multiple attachments for furniture, crevices and delicate surfaces to handle various cleaning tasks.
Yes, the 18V battery is part of the Power For All Alliance system, making it compatible with over 100 Bosch tools and 10+ other brand tools. This includes garden tools, power tools and other household appliances. The battery features protection against overheating, overcharging, self-discharge and memory effects, ensuring long-term reliability across all compatible devices.
The HEPA filter features RotationClean technology for easy maintenance. Simply rotate the filter mechanism to knock dust particles loose - this should be done regularly to maintain optimal suction. Occasionally, you may need to use compressed air to blow through the filter for deeper cleaning. The filter is designed to capture over 99.99% of particles and allergens whilst maintaining airflow efficiency.
The vacuum includes a MicroClean brush with LED lighting, soft furniture brush, short crevice nozzle, long flexible crevice nozzle, 3.0 Ah battery, quick charger and docking station. All attachments connect securely to the main unit with a tight-fitting mechanism. The foot-operated nozzle release allows easy switching between attachments. The docking station provides convenient storage and charging in one unit.
