WISAG and LionsBot's R5: Facility Services Meets Robotics

What did WISAG and LionsBot announce?

On April 8, 2026, LionsBot International and WISAG Facility Service announced a collaboration on the R5, an autonomous floor scrubber developed with practitioner input from WISAG. The announcement came ahead of Interclean Amsterdam, which ran 14 to 17 April 2026.

The short answer: a German facility services firm helped shape how a robot performs in day-to-day commercial cleaning, while the robot maker stayed responsible for the machine. For US contractors, that split is the part worth studying.

Why did a service firm help shape the robot?

According to the PR Newswire release, WISAG shared operational insights and practitioner feedback on usability, reliability and readiness for commercial deployment. WISAG's Andreas Heinzel, managing director of its Commercial Cleaning unit, is quoted in the release.

Both companies frame the work around labour shortages and rising operational demands in cleaning. A cleaning contractor sees the robot at the hours when a battery runs low or a route jams, and that feedback reaches details a spec sheet never lists.

A third-party review from antonrobots says WISAG describes roughly two years of development and positions the R5 as an evolution of the R3 Pro. That timeline does not appear in the press release, so treat it as reported rather than confirmed.

What does the R5 do on a hard floor?

LionsBot's product page describes the R5 as an autonomous floor scrubber that can also run walk-behind. The vendor lists up to 5,000 m² per charge, a 520 mm cleaning path, a 360 degree turn-in-place, a maximum run time of 4 h 20 min and a charging time of 3 h 30 min.

The machine weighs 200 kg, with a 50 L solution tank and a 40 L recovery tank. Average sound is listed at 70 dB, and the filter is H13 HEPA. Navigation combines 3D LiDAR, depth and RGB cameras, 2D LiDARs, sonars and time-of-flight sensors.

The independent reviewer is direct about scope. The R5 is primarily a hard-floor scrubber, not a carpet vacuum or stair cleaner, and real output depends on route, foot traffic, obstacles and water servicing. At 200 kg, it also needs suitable floors, access, charging space and a recovery plan.

LionsBot's range also includes the R3 Scrub Pro, a compact scrubber for narrow aisles at 800 to 1,200 m² per hour, and the R3 Vac. A narrow-aisle building may fit the smaller unit better than the R5.

How many units does a daily area need?

The vendor's sizing rule is simple. Divide the daily area by 5,000 m², round up, and assume one charge cycle per robot per day. A 12,000 m² nightly zone works out to three units under that rule.

The vendor's illustrative figure is that at 5,000 m² an R5 gives back about three hours a day to the team. That is the vendor's own framing, not a measured result at your site.

The trial numbers are also vendor-reported. The antonrobots review describes an Excellerate trial with LionsBot that cleaned 24,000 m² in one month, reached 99.8% program completion and returned 51 hours to the team. A distributor's hospital report describes 1,196 m² in a single 1 h 12 min run, about 991 m² per hour with 99% coverage on one route. Treat these as the shape of a claim, then test them on your own floor.

How do the maker and the service firm split the work?

The useful lesson in this model is the division of labor. The robot maker supplies the machine, its navigation, its LionsOS cloud scheduling and monitoring, and its certifications. The R5 page lists ISO 9001, ISO 14001, ISO 45001, ISO 27001, SOC 2 and a GDPR compliance statement.

Deployment and upkeep sit with whoever knows the building. A service contractor should bring the following to the table before go-live.

• A floor map that marks carpet, thresholds, ramps and wet areas the robot must avoid
• A water servicing route, because a scrubber is only as productive as its refills and drains
• A charging location with clearance, power and a path that does not block exits
• A recovery plan for a unit that stalls, along with a named person who gets the call

What does this signal for US facility service contractors?

The WISAG fleet figures are the most striking claim, but they come from secondary reporting. The antonrobots review says WISAG planned in June 2026 to add 300 R5 units by year end, lifting its cleaning robot fleet above 500, with R5 units in use at about 150 customers. The press release does not confirm those counts, so cite them as reported.

For a US contractor, the signal is about sequence. Pilot one route, measure the hours returned, then grow the fleet. LionsBot's site says it has a dealer network across more than 40 countries, including the United States, for local sales, deployment and after-sales support. Ask who answers at 2 a.m. in your region.

Where does Service Robot Co. fit this model?

Service Robot Co. works from the other side of the same table. We are OEM-neutral, so we pick the right robot across manufacturers for each floor, then finance, deploy, integrate, train and service every unit through a nationwide US engineer network. One partner covers the whole lifecycle.

Customers lease robots from us on a 3-year lease with one fixed payment, quoted after a site assessment. That assessment is where the floor, water, charging and crew questions above get answered before anyone signs.
