Kärcher BVL 3/1 Bp Cordless Backpack Vacuum Cleaner

The Kärcher BVL 3/1 Bp is an ultra-lightweight cordless backpack vacuum cleaner designed for professional cleaning in tight, awkward and hard-to-reach areas.

Powered by Kärcher’s 36V battery platform, it gives operators the freedom to clean without trailing power cables while keeping the machine comfortably positioned on the back. With a 3-litre container and a carrying weight of just 4.5kg, the BVL 3/1 Bp is particularly well suited to stairways, confined areas and spot-cleaning tasks where conventional floor vacuums may be less practical.

Ultra-Lightweight Backpack Design

The BVL 3/1 Bp is manufactured using lightweight EPP expanded polypropylene, allowing Kärcher to create a robust professional vacuum with a very low overall carrying weight.

Kärcher states that the backpack unit has a carrying weight of just 4.5kg, helping reduce strain during longer cleaning periods and making the machine easy to transport between work areas.

The EPP construction is also designed to be particularly tough and hard-wearing despite its low weight.

36V Cordless Cleaning

The BVL 3/1 Bp operates on Kärcher’s 36V battery platform, allowing operators to work without relying on nearby electrical sockets.

This makes the machine particularly useful for stairs, corridors, confined areas and environments where cables could restrict movement.

The removable battery can also be quickly transferred between compatible Kärcher 36V machines, helping improve flexibility across professional cleaning operations.

Ergonomic deuter® Carrying System

Kärcher equips the BVL 3/1 Bp with a deuter® carrying frame designed to remain comfortable during longer periods of use.

A control panel positioned directly on the waist strap gives the operator easy access to the machine’s main functions without needing to remove the backpack.

The suction hose can also be connected in different positions to accommodate both right-handed and left-handed users.

eco!efficiency Mode

Kärcher’s eco!efficiency mode reduces the machine’s energy consumption and operating noise while extending battery runtime.

With a compatible 5.0Ah battery, Kärcher lists a maximum runtime of up to 52 minutes in eco!efficiency mode and up to 31 minutes in Power mode.

When fitted with a 7.5Ah battery, maximum runtime increases to up to 73 minutes in eco!efficiency mode or 41 minutes in Power mode.

Strong Professional Performance

The BVL 3/1 Bp delivers an airflow of 35.4 l/s and a vacuum of 189 mbar / 18.9 kPa from its 350W motor.

This gives the machine the suction performance required for regular professional dry cleaning while retaining the mobility of a compact cordless backpack design.

Kärcher lists an approximate cleaning performance of 120 m² per charge with a 5.0Ah battery and around 130 m² with a 6.0Ah battery.

Brushless EC Motor

A brushless EC motor is used to provide high wear resistance and a long service life.

The reduced mechanical wear associated with the brushless design helps make the machine suitable for regular professional use, while also supporting longer working periods and improved productivity.

Compact 3-Litre Capacity

The BVL 3/1 Bp uses a compact 3-litre container, keeping the machine small and lightweight enough for backpack use.

It weighs 4.1kg without accessories and measures 220 x 317 x 450mm, making it easy to carry and manoeuvre in areas where space is limited.

Optional HEPA 14 Filtration

For applications requiring a higher standard of fine-particle filtration, a HEPA 14 filter is available as an optional accessory.

This gives users the flexibility to upgrade the filtration system where additional hygiene requirements need to be met.

Practical Accessories

The BVL 3/1 Bp is supplied with the essential tools required for professional dry cleaning.

Standard equipment includes a 1m suction hose with bend, antistatic bend with air-flow regulator, aluminium telescopic suction tube, switchable floor nozzle, crevice nozzle, fleece filter bag and motor protection filters.

Ideal For

The Kärcher BVL 3/1 Bp is particularly well suited to cleaning areas where mobility and compact dimensions are more important than large container capacity.

Typical applications include stair cleaning, spot cleaning, school maintenance work, trade environments and other situations where conventional floor-standing vacuum cleaners may be awkward to manoeuvre.

Its lightweight backpack design also makes it suitable for moving quickly between rooms, floors and confined spaces.

Why Choose the Kärcher BVL 3/1 Bp?

The Kärcher BVL 3/1 Bp combines 36V cordless operation, an ultra-light backpack design, strong professional suction performance and excellent operator mobility in a compact 3-litre machine.

Its lightweight EPP construction, ergonomic deuter® carrying system, brushless EC motor, eco!efficiency mode and waist-mounted controls make it a practical solution for professional users who regularly clean stairs, confined areas or locations where maximum freedom of movement is required.

An optional HEPA 14 filter also allows the filtration system to be upgraded for more hygiene-sensitive environments.

Please note: this particular 1.394-300.0 version is supplied without a battery or charger, which must be purchased separately.
