LionsBot R12 Rex Scrub · specs, operator review and alternatives (2026)

The LionsBot R12 Rex Scrub is a large industrial autonomous floor scrubber for shopping centres, airports, warehouses and car parks. It scrubs an 810 mm path, carries 140 L of clean water and 140 L of recovery water, with high brush pressure (80 kg) and an observed productivity of 1,700 to 2,500 m²/h. It is deployed on reference sites (Gatwick Airport, Our Tampines Hub). Worth knowing: LionsBot publishes contradictory figures for its weight, to be clarified before any project on a raised floor. Price and availability on request.

Reading by environment

Floor area tier140 L tanks and observed productivity of up to 2,500 m²/h: large industrial and airport floors. The optional Refuel Station extends operating time.
Footprint / aislesA heavy (up to 690 kg) and wide (810 mm) machine: very large, open sites.
Floors and soilingHigh brush pressure (80 kg) on stubborn hard-floor soiling. No carpet. Large debris must be pre-swept.
Public / opening hours70 to 75 dBA depending on the source: better suited to hours without a dense public presence. Airport references (Gatwick) point to use in busy environments.
Floor / topography6° gradient in manual mode only: to be confirmed for autonomous mode.
Raised floors / mezzaninesPoint of caution: the weight ranges from 457 to 690 kg depending on the LionsBot source, a 233 kg gap that decides whether raised floors and mezzanines are eligible. It must be pinned down at quotation stage.

Floors and soiling

A large industrial scrubber for hard floors: adherent, stubborn soiling on concrete, epoxy and tiles, thanks to the high pressure (80 kg). No carpet. Bulky debris must be pre-swept. A deep-scrubbing machine for very large open floors.

What the manufacturer does not say

LionsBot contradicts itself on several figures. Weight (457 to 690 kg), runtime (5 to 8 h), noise level (70 to 75 dBA) and LiDAR range (200 to 240 m) differ between the product page, the brochure and the distributors. All of them should be checked in real conditions, the weight above all.

The weight gap is a genuine site issue. 233 kg between sources: on a raised floor or a mezzanine, this is the figure that decides feasibility. Secure it before any commitment.

Long charging and lead-acid battery. 8 to 10 h of charging: plan the schedule accordingly. Cost structure: machine + optional Refuel Station + consumables.

Purchase or full-service contract

On purchase (capex), the stated weight varies by 233 kg depending on the source (457 to 690 kg), a decisive gap on a mezzanine or raised floor that must be resolved before buying. Under a full-service contract (opex), the contractor takes on that site check and operational continuity. See the Pudu range and the on-site demonstration, or our robotic cleaning service.
