Battery-power vacuum cleaner VCS 7-28 Infinity Signature Line

The VCS 7-28 Infinity Signature Line cordless vacuum cleaner with patented Smart Power technology: adjusts the power output to suit the floor type, level of dirt and filter condition, ensuring consistent suction power.

Only selected top-of-the-range models bear the signature of the company’s founder, Alfred Kärcher. The VCS 7-28 Infinity Signature Line vacuum cleaner offers automated cleaning: In Smart Mode, the patented Smart Power technology continuously analyses the floor surface, the amount of dirt and the condition of the filter, and adjusts the motor rating, roller and airflow in real time. This ensures that the suction power remains consistently high – without any loss of performance⁶⁾. On carpeted floors, the system automatically increases the roller speed for a more thorough clean. The patented floor nozzle picks up dirt whilst moving forwards and backwards, achieving up to 100 % dust pick-up²⁾. The 125° wide-angle LED light illuminates the area in front of the nozzle, whilst the anti-hair technology minimises hair tangles on the roller³⁾. The multi-stage HEPA filter system filters out 99.9 %⁴⁾ of the particles from the exhaust air. Contactless fine filter cleaning enables rapid cleaning without direct contact with dirt. The device can be operated according to your needs with three suction modes and a run time of up to 70 minutes¹⁾.

Features and benefits

Automatic floor type detection with Carpet Turbo 

The right power for every floor: In Smart Mode, the system automatically detects the floor surface and adjusts the cleaning performance accordingly.Powerful Carpet Turbo: On carpets, the vacuum cleaner automatically switches to up to 3,400 rpm⁸⁾ to dislodge dirt deep within the fibres.Easy to use: The automatic adjustment ensures thorough results, without the need for any manual switching.

Dirt detection and power adjustment

More power for heavy soiling: When the level of soiling is high, the power output in Smart Mode is automatically increased within 100 ms⁹⁾.Demand-based control: The power is automatically adjusted to the amount of dirt. This helps to conserve battery run time during normal use.Adjusted cleaning time: The sensor’s precise response to the amount of dirt ensures rapid and needs-based cleaning.

Smart filter monitoring for consistent suction power

No loss of suction power⁶⁾: The system monitors the filter condition and, in Smart Mode, automatically adjusts the power output to ensure a consistently high vacuum.Timely filter-full alert: The automatic notification when the filter is full prevents unnecessary increases in power consumption in Smart Mode and helps conserve battery life.Reliable suction power: The filter indicator prevents a drop in performance even in the other modes, ensuring thorough cleaning results.

Patented forward-reverse floor nozzle

100 % dust pick-up on hard floors²⁾: The special nozzle design ensures that dirt is picked up both when moving forwards and backwards.

Time-saving dirt pick-up: Cleaning in both directions significantly reduces the amount of work required.

High manoeuvrability: The nozzle’s design allows for flexible manoeuvring around furniture and corners.

Flexible articulated tube and 125° wide-angle floor light

Long reach: The flexible articulated tube makes it easy to clean under low furniture – without having to bend down at all.

Improved visibility: The 125° wide-angle floor light makes fine particles clearly visible, even in dark areas and under furniture.

Easy to use: The combination of high flexibility and illumination helps to ensure thorough dirt removal.

Anti-Hair technology

99 % fewer hair tangles³⁾: The floor nozzle noticeably minimises the amount of hair that gets tangled around the roller brush whilst vacuuming.

Less cleaning required: As hardly any hair gets tangled around the roller, the brush needs to be cleared of clumps of hair by hand less often.

HEPA filtration & device maintenance

99.9 % pure exhaust air⁴⁾: The HEPA exhaust air filter traps even the smallest particles and is suitable for people with allergies. It is not necessary to replace the filter.

Quick hygiene checks on the go: The fine filter is cleaned contactlessly using a lever in just a few simple steps, without you coming into contact with any dirt

Thorough cleaning: The dust container can be completely removed for cleaning, and the metal coarse filter can be washed. Access to the suction channel inside the housing clears blockages immediately.

Ease of use & digital displays

Status check: The LCD display shows the remaining operating time. The LED panel displays the mode and power level.

37 languages to choose from: The menu can be set to your preferred language for ease of use.

Run time & modes: run time of up to 70 minutes¹⁾ in Eco!mode. There are four modes available for different cleaning tasks.

Accessories & freestanding charging station

Drill-free storage: The freestanding station requires no drilling into walls and charges both the device and an optional second battery.

Versatile accessory kit: includes a mini turbo brush, crevice nozzle and soft dusting brush for targeted cleaning of various surfaces.

Specialised brush for upholstery and pet hair: The mini turbo brush removes dirt and pet hair from mattresses and upholstery.

Signature Line quality & equipment

Premium promise: Alfred Kärcher’s signature marks the top model in the range, which includes an extended warranty and app support.

High flexibility: An easily replaceable battery ensures uninterrupted work.

Reduced operating noise: The integrated noise reduction system limits the sound power level to 77 dB(A)⁵⁾ whilst vacuuming.

¹⁾ Run time applies to operation at the lowest power setting in ECO!mode without the electric floor nozzle. The actual run time varies depending on the suction level selected and the degree of soiling. Based on internal tests in accordance with IEC 62885-4, Clause 5.1.
²⁾ Dust intake on hard floors with a crevice attachment, measured in accordance with standard EN IEC 62885-4:2020/A1:2023. Based on internal tests.
³⁾ Measured using an in-house test procedure for hair pick-up, using 30 cm long strands of hair (0.5 % residual entanglement in the test setup). Based on internal tests.
⁴⁾ Filtration of fine particles (size ≥ 0.3 µm) measured in accordance with standard IEC 62885-2:2021/-4:2020, Clause 5.13. Based on internal tests.
⁵⁾ Sound power level measured in accordance with standard EN 60704-2-1. Based on internal tests.
⁶⁾ Measurement based on IEC 62885-2:2026, carried out in Smart mode using a floor nozzle with a dust intake capacity of up to 150 g (DMT-8 dust). Based on internal tests.
⁸⁾ Maximum speed achieved with the roller brush in Smart mode on carpet. Based on internal tests.
⁹⁾ Measurement of the response time of the sensor system for power adjustment in Smart mode. Based on internal tests.
