## L4 questions

How often can the L4 run?+

Up to 4.5 hours per charge. It recharges in 2.5 hours, so it can run more than once a day.

Does the L4 refill itself?+

Yes, with the CWS-01 workstation. It refills water and detergent, drains dirty water and recharges the L4.

Can I see the L4 before deciding?+

Yes. Book a demo and we will run it on your floor.

## Interested in the L4?

See it on your own floor, or ask the team for more detail.
