Sensor Bagless Technology

Sensor-controlled performance monitoring system, this unique technology not only ensures an outstanding level of cleaning performance it also keeps maintenance to a minimum. No follow-up costs as the washable high-tech filter materials last as long as the appliance and there is no need to buy replacement dust bags.

Easy Clean

The dust container can be removed in just one movement at the touch of a button and is so easy to clean as it does not have any corners in which dirt can accumulate.

Sensor Control

A sensor continuously monitors the cleaning performance of the vacuum cleaner. The appliance always vacuums at the optimum performance level and as a result, reduces the amount of cleaning to a minimum.

Quattro Power System

The QuattroPower System is Bosch’s high-performance technology for outstanding cleaning results with low energy consumption. This highly efficient system is based on the unique combination of the HiSpin Motor, high-performance nozzle, optimized air seals and efficient dust separation system.

Class C Performance Hardfloor

The hard floor cleaning performance class measures the dust pick-up on hard flooring. The higher the performance class, the more thorough the cleaning results on flooring with crevices and gaps, such as tiles and floorboards.

Performance Control

Optimum cleaning performance for all floors. Thanks to the electronic performance control, it can be easily adjusted using the rotary control.

Air Seal

A densely constructed air seal reduces any potential loss of airflow. This is key for maintaining strong suction power to ensure all dust and dirt is removed.

Dust Separation System

The efficient dust separator system prevents any decline in performance and minimises the maintenance typically required for bagless vacuum cleaners. Ensuring the vacuum provides a reliable lifetime performance.

High-Performance Nozzle

A new generation of high-performance floor tools for Bosch vacuum cleaners ensure high dust pick-up on carpet and hard flooring. Ensuring perfect results everytime.

Bosch Cylinder Vacuum Cleaner | BGS4312GB is rated 3.5 out of 5 by 2.
Rated 5 out of 5 by from Best vacuum cleaner I've ever owned Although it's been 5years since i bought mine. It has served me really well. Bearing in mind i have severe dust allergies and use it everyday. This has worked well for me in that sense especially. Cleaning is simple and easy. Suction is really powerful for a small compact size and when on min it is very quiet. i have had over 7 different hoovers in the last 10 years including a dyson.and this has last me the longest. It's a shame that i can't seem to find anymore being sold in the UK! Thank you Bosch for making such amazing products but please make more of these and sell in the UK!

Rated 2 out of 5 by from Not efficient Pro: Verry silent. Easy to clean Con: Verry bulky. Verry poor suction. A vacuum main characteristic is its capacity to clean, thus suction. The rest are nice to have.
