The suction engineering of this unit relies on a 23.3 W motor optimized for high-velocity airflow rather than raw torque. Generating 3000 Pa of static pressure, the motor-to-airway ratio is calibrated to maintain consistent lift across its 1 L bagless chamber. While this pressure level is lower than heavy-duty corded extractors, it is specifically tuned for surface-level debris like fine road dust and hair on hard flooring. The trade-off results in lower thermal output, allowing the motor to operate efficiently throughout long cleaning sessions without significant suction drop-off as the battery depletes.
The filtration architecture employs a 1-stage HEPA system that targets particulate matter down to 0.3 microns. By using a washable pleated media, the design addresses the high-dust environment typical of Indian urban areas, where fine silt can quickly clog non-HEPA filters. The mechanical seal around the filter housing ensures that captured dander and allergens remain trapped, preventing exhaust bypass. For the user, this means that mattress hygiene and pet hair removal do not result in dust being recirculated into the room air, making it suitable for households with respiratory sensitivities.
The battery system uses a high-capacity cell configuration to achieve a 180-minute runtime, a rarity in the cordless segment. It utilizes a Constant Current-Constant Voltage (CC-CV) charging protocol via a 6-hour cycle to maximize the lifecycle of the lithium-ion pack. Given the 23.3 W draw of the motor, the discharge rate is relatively shallow, which prevents excessive heat buildup within the handle assembly. This engineering choice prioritizes endurance for full-home coverage over high-burst power, making it a practical choice for 2BHK and 3BHK apartments where cleaning time is a priority.
For wet and dry operations, the unit incorporates a dedicated baffle design within the 1 L container to separate liquid intake from the motor housing. The 2-in-1 tank allows for simultaneous management of dry debris and light liquid spills on mosaic or vitrified tiles. To prevent mold growth or motor damage, the internal moisture sensors trigger a shutdown if the liquid level exceeds the safe threshold. Users must maintain the reusable mop and side brushes post-wet-use to ensure the mechanical components remain free from calcification, especially in regions with hard water supplies.
The blower function utilizes a secondary exhaust port redirected through a narrow nozzle to increase air exit velocity. Technically, this transforms the vacuum from a negative-pressure extractor into a positive-pressure air mover. This mechanism is particularly effective for cleaning WFH keyboards and AC vents where physical brush contact is difficult. By reversing the airflow path, the blower can clear dust from cooling fans and intricate electronics that would otherwise require compressed air cans, adding a layer of mechanical versatility that extends beyond standard floor cleaning.
The chassis is constructed from high-impact ABS plastic, bringing the total weight to 3 kg. This weight is distributed with a low center of gravity to reduce wrist strain during extended floor use. The ergonomic handle includes a trigger lock to prevent finger fatigue during the 180-minute operation window. The parking position and compact profile allow the unit to be stored easily in utility balconies or small closets. Ultimately, the engineering of the GB Classic C1 prioritizes sustained usability and multi-surface adaptability for the unique challenges of the Indian domestic environment.
