Gausium Scrubber 50 Pro vs Kärcher KIRA B 50: autonomous scrubber comparison
Spec-informed comparison of the Gausium Scrubber 50 Pro and Kärcher KIRA B 50 autonomous floor scrubbers for Australian retail, airports, and mid-sized commercial sites.
Kärcher's KIRA B 50 and Gausium's Scrubber 50 Pro are both mid-size autonomous floor scrubbers aimed at supermarkets, retail chains, and commercial hard-floor environments. This comparison focuses on the Scrubber 50 Pro (disc brush configuration) against the KIRA B 50 on published technical parameters. Gausium also offers Omnie for sites that need optional sweeping and dust-mopping on the same platform — Robotec supplies the full Gausium range in Australia under Purchase, Lease, and RaaS.
Gausium Scrubber 50 Pro
Mid-size dedicated autonomous floor scrubber (disc brush) with optional dust-mopping, spot cleaning, and 5-stage filtration. Distributed in Australia by Robotec.
Best for
- Hard-floor-dominant sites where scrub-dry is the primary daily task
- Narrower aisles — min passing width ~800 mm
- Operators who want closer wall-edge cleaning (squeegee 0–10 mm)
- Sites that benefit from spot cleaning and 5-stage water filtration
Watch-outs
- Disc brush version does not sweep — roller brush configuration adds sweeping
- Smaller clean/recovery tanks than KIRA B 50 (30 L / 24 L vs 55 L / 55 L)
Kärcher KIRA B 50
Kärcher autonomous floor scrubber with integrated sweeping, larger water tanks, and a heavier platform suited to open commercial hard floors.
Best for
- Operators already standardised on Kärcher equipment and dealer channels
- Sites that want scrubbing and sweeping in one KIRA platform
- Longer scrub runtime per charge (~3.5 h vs ~3 h on Scrubber 50 Pro disc)
- Larger water tank capacity (55 L clean / 55 L recovery)
Watch-outs
- Larger footprint — min passing width >1,000 mm
- Wall-edge distance typically >100 mm vs Scrubber 50 Pro squeegee at 0–10 mm
- No spot cleaning mode on published KIRA B 50 specifications

The verdict
Scrubber 50 Pro is a strong fit when aisle geometry is tighter, closer wall-edge scrubbing matters, or you want spot cleaning and 5-stage filtration on a lighter platform. KIRA B 50 is a strong fit when you need larger onboard water capacity, integrated sweeping in one unit, or you are extending an existing Kärcher fleet. For sites that also need dust-mopping or 3D LiDAR, Gausium Omnie is worth evaluating alongside Scrubber 50 Pro. Robotec can arrange a site-specific demo against any Kärcher autonomous model you are shortlisting.
