Carpet, hard floor, and the dust in between.
The LionsBot R3 Vac is an autonomous commercial vacuum robot for offices, retail and narrow indoor spaces. It cleans carpet and hard floors, and at 61.7 dB it runs with people still on the floor.
The numbers
Built for the floors a big machine cannot reach.
Cleaning path
Widens to 550 mm with the side brush fitted, so it reaches the edges as well.
Machine weight
Light enough for upper floors and passenger lifts without special access.
Full recharge
From empty to a run of up to 3 hours.
The R3 Vac advantage
Small machine, full job.
Suction
Carpet and hard floor.
The R3 Vac lifts debris and fine dust from carpet as well as hard floors, and filters what it collects through a HEPA filter into a microfibre dust bag. That is work a floor scrubber cannot do at all, which is why it is at its best in carpeted offices. The robot takes the open carpet and the cleaning team keeps the detail work.
- HEPA filtrationFine dust is captured rather than moved around the room.
Footprint
Goes where the floor narrows.
At 521 by 482 mm and 655 mm tall, the R3 Vac works the narrow routes a full-size machine cannot enter: single-file corridors, the gaps between desks, and the aisles inside fixed seating. Its 25 m LiDAR still reads the whole room while it works one narrow part of it. Those are the routes a cleaner would otherwise cover by hand.
- 550 mm with the side brushThe side brush widens the 350 mm path without changing the machine's footprint.
Intelligence
Plans its own path.
AI SmartClean plans the route, adapts to whatever appears in front of it and recovers its own path without help. Zones are set with MagicTag™, so the team sets a zone by placing a tag on site, not by drawing a map.
- MagicTag™ zonesSet and changed on site, so there is no map to draw.
- 61.7 dB averageThe quietest machine in the range, so occupied floors stay usable.
See it run
The complete vacuum solution.
Two ways to run it
Autonomous, or hands on.
Set a zone and the R3 Vac cleans it on its own. When a spill or a corner wants a person, take the handle and vacuum it yourself, then hand the floor back with one tap on the screen. The same machine covers both, so nobody waits for the other.
Average practical efficiency when it runs on its own, on carpet and hard floors alike.
Maximum run time per charge, then an automatic return to the charging station and two hours to full.

Scale and profitability
The vacuum robot that scales your team.
Set the zones once with MagicTag™ and the R3 Vac does the repeated work. One person can look after several robots, so each shift covers more floor without hiring more people.
- 82 eight-hour shifts
- 2 R3 Vac units needed
- €14,586 at your rate
How this is calculated, including the 15% supervision assumption
Units needed is your daily area divided by the R3 Vac’s 1,400 m² coverage per charge, rounded up. That assumes one charge cycle per robot per day, which suits a single shift; a site that runs longer gets more than one cycle from each robot, so it needs fewer. Run hours use 800 m² per hour, the top of the R3 Vac’s published efficiency range of 500 to 800 m²/h. Taking the top of the range gives the smaller of the two possible figures, so the number above is the cautious one. The supervision share is reserved for emptying the 6 L dust bag, spot checks and watching the robot: the R3 Vac carries no water, so there is nothing to fill or drain. Only the hours left over count as freed up, spread across 52 weeks. Shifts are those hours divided by eight. The value is the same hours priced at the rate you entered, in the currency you chose, with no conversion applied. Actual results vary by facility complexity and labour market conditions.
LionsCloud
Every run, logged and accountable.
The R3 Vac reports to LionsCloud, LionsBot's fleet software. Schedules, coverage and completion are recorded automatically, so cleaning becomes a record you can hand to a client rather than a claim you have to make. The team can see which zones are done before the shift ends.
- Schedule zones once and let the fleet repeat them
- Automatic coverage logs for every completed run
- One view across every robot you run
Fleet management
Fleet management, zone by zone.
Three R3 Vacs, three zones, one shift. The cleaning team sees exactly what each robot covered before the shift ends, so nobody has to walk the floor to find out.

R3 Vac questions, answered.
What is the LionsBot R3 Vac?
The R3 Vac is an autonomous commercial vacuum robot built for offices, retail floors and indoor spaces with narrow pathways. It vacuums carpet and hard floors on a 350 mm path, which widens to 550 mm with the side brush fitted, and it runs its schedule without an operator on the handle.
How much floor can the R3 Vac clean in an hour?
The R3 Vac covers between 500 and 800 m² per hour, which is the average practical efficiency LionsBot publishes for it. On a single charge it covers up to 1,400 m², about 15,000 ft², and it runs for up to three hours before returning to charge, which takes two hours.
Is the R3 Vac quiet enough to run while people are working?
The R3 Vac averages 61.7 dB, which is quieter than a typical office conversation and the quietest machine in the LionsBot range. That is what makes it usable on occupied floors during the day rather than only after hours.
Does the R3 Vac work on carpet as well as hard floors?
Yes. The R3 Vac has the suction to lift debris and fine dust from both carpet and hard floors, and it filters what it picks up through a HEPA filter into a microfibre dust bag. That combination is why it suits carpeted offices, which a floor scrubber cannot clean at all.
How small a space can the R3 Vac get into?
The R3 Vac is 521 mm long, 482 mm wide and 655 mm tall, and weighs 53 kg. That footprint is what lets it work along narrow corridors, between desks and around fixed seating, where a full-size machine cannot go.
How much setup does the R3 Vac need?
Cleaning zones for the R3 Vac are set with MagicTag™, so a map and a cleaning path are created without writing anything or clicking through a plan. After that the robot follows its schedule, adapts to obstacles in front of it, recovers its route on its own, and returns to its charging station when the battery runs low.
How do I buy a LionsBot R3 Vac?
The R3 Vac is sold through LionsBot's certified dealer network rather than direct. Dealers in more than 40 countries handle sales, site survey, deployment and after-sales support. You can contact us and we can schedule a virtual call with you about the R3 Vac or match you with a local dealer.
