Floor Scrubber

Overview

The floor scrubber is a self-propelled walk-behind machine for cleaning large hard-floor areas in a single pass. It carries its own clean water and detergent, scrubs the floor with rotary brushes, and reclaims the dirty water through a trailing squeegee, leaving the surface nearly dry behind it. A deep-cycle battery pack powers the brushes, vacuum, pump, and traction drive so the machine runs untethered.

A welded steel frame carries every subsystem inside molded shrouds and a wrap-around bumper. The operator steers from a handle console while a central controller sequences the cleaning functions.

How it works

Clean water and detergent fill the Solution Tank. The Solution Delivery System meters this onto the floor through a pump, solenoid valve, and adjustable flow control, wetting the surface ahead of the brushes.

The Scrub Deck does the cleaning. Two rotary discs, each turned by its own DC motor through a reduction gearbox, scrub the wetted floor under adjustable down-pressure. A lift actuator raises the deck off the floor for transport and when reversing.

Behind the deck the Vacuum & Squeegee System recovers the water. A high-speed bypass vacuum motor pulls suction at the trailing squeegee, whose replaceable blades channel the dirty water into the pickup hose and up into the Recovery Tank. A float shutoff seals the vacuum inlet when that tank fills, protecting the motor.

The machine moves itself through the Traction Drive: a DC traction motor drives a wheel through a reduction transaxle, with swivel casters supporting the rear. Speed is set from the handle.

Energy comes from the Battery Pack, a deep-cycle lithium pack with a BMS, a 12 V accessory battery, and an onboard charger. The Control Board ties it together, switching the motors and pump through relays and MOSFETs from operator commands on the membrane panel.
