Key facts
- Product page (nilfisk.com Canada, product no. 56104508, fetched 2026-10-17): up to 6 h runtime and 55,000 sq ft per charge, 98-99.5% route coverage, third-party robotic-safety certification. The page shows no specification table. The 6 h figure is a maximum, so battery_hours is left empty.
- Provenance: the technical values below come from Nilfisk's Liberty SC50 fact sheet (form L1234A, 11/2019, US models 56104507 REV and 56104506 Disc), a PDF read on a dealer-hosted copy (https://www.rigolift.com/wp-content/uploads/2022/01/Liberty-SC50-fact-sheet.pdf, read 2026-10-17). It is not the cited nilfisk.com page, whose product number (56104508, 'X51D OBC PH') may be a newer or different configuration; the match is unconfirmed, so the specs are marked backfilled (no verification claim). Later hardware revisions may differ.
- Fact sheet values: 20 in (51 cm) scrub path, 15 gal (57 L) solution tank, 14 gal (53 L) recovery tank, 24 V, battery up to 255 Ah, IPX4, 63 dB(A) sound level, 76.7 cm squeegee, 135.5 x 76.1 x 144.1 cm (144.1 cm is height to the top of the antenna).
- Speeds: 1.055 m/s autonomous (3.8 km/h converted), 5.0 km/h manual forward. Gradeability: 2% (1.15 degrees) autonomous, 9% cleaning manual, 15% transport. Theoretical productivity 2,453 m2/h. Brush speed 157 rpm (disc) or 2250 rpm with 10-30 rpm macro orbits (REV).
- Fact-sheet gross weight is 484.4 kg (REV) / 479.5 kg (Disc) but includes a full solution tank, batteries and a 75 kg operator, so no net weight is recorded. Optional UVGI disinfection module, SmartFlow and EcoFlex are listed on the product page.
