Clarke® CA60 Walk Behind Automatic Floor Scrubber Review

Choosing between several different walk-behind floor scrubbers can be challenging, especially when some of the machines offer many of the same features and benefits.

To help you narrow down your choices, we compared the best 4 walk-behind floor scrubbers of 2021 in a previous article. 

The Clarke® CA60 automatic floor scrubber made it on that list. It offers some key benefits that make it one of the most efficient scrubbers. 

What makes the Clarke® CA60 walk-behind floor scrubber one of the best autoscrubbers?

The Clarke® CA60 is extremely versatile. It can be purchased as either a disc or orbital scrubber, as traction or non-traction drive, and can be purchased in scrub head sizes ranging from 20 to 24 inches. 

CA60 20B rightDisc scrubbers utilize a round scrub disc and round floor pad or brush. They rotate the floor pad or brush in circles to clean the floor. 

Orbital scrub heads “orbit” or move in fast, tight vibrations to clean the floor. On this machine, the orbital scrub head is known as BOOST® technology.

When purchased with BOOST® technology, this machine is a cost-effective and environmentally-friendly auto scrubber because it reduces the amount of chemicals and water needed to clean. 

Pro Tip: When used with a surface preparation pad (SPP), this machine can take several coats of wax off the floor with just water in the tank.


In this article and video, we’ll provide a comprehensive review of some of the features and benefits that make the Clarke® CA60 auto scrubber one of the best walk behind automatic scrubbers of 2021.


The Clarke CA60®  is powered by two batteries which provide up to 3 hours of cleaning time.

Providing cord-free maneuverability, this walk-behind, battery powered scrubber allows you to reach beyond the length of a cord. 

When an operator has to move the cord from outlet to outlet, it reduces worker productivity. Corded floor scrubbers also require the operator to carefully maneuver around the cord, mindful not to run or trip over the cord. 

On-Board Battery Charger

CA60 battery charger-1Every Clarke® CA60 autoscrubber comes standard with an on-board battery charger. 

With an on-board charger, batteries can be charged at any 120V outlet to maximize run time and the overall life of your batteries. 

Pro Tip: When any autoscrubber is plugged into an on-board battery charger, it can not be operated.

With an on-board charger, custodial staff can avoid having to bring the machine to a specific charging area or station, boosting productivity. 

Pro Tip: You should always charge machine batteries to 100% before operating the machine. Do not “opportunity charge”, or charge the battery whenever you get the chance. Disconnecting and using the battery before it reaches a full charge will shorten the life of the battery, causing you to have to invest in new batteries more frequently.


Non-Traction Drive Or Traction Drive

The Clarke® CA60 can be purchased with non-traction or traction drive.

Non-traction drive is good for even, flat floor areas or for operators who like full control over the movement of the machine. Non-traction machines rely on the floor pad to help drive the machine. 

Traction drive is perfect for floors that have inclines or ramps. 

Traction drive has its own separate motor for driving the machine. The operator has a speed control which he/she can set a specific speed for the entire machine. 

The machine speed is set based on the surroundings. For example, if there are people in the area, they will need to operate the machine slower. A dial on the operator handle sets the cruising speed for safe and comfortable operation and control. 

Once the speed is set, the traction drive autoscrubber moves itself only requiring the operator to guide the machine on a cleaning path. It does not require the operator to push the floor scrubber along, helping reduce operator fatigue.

Traveling at a consistent speed also allows the scrubber to effectively clean the entire floor area at the same rate.

Traction drive is more expensive than a non-traction drive, but the increased productivity can off-set the initial costs. When your staff can perform cleaning procedures quicker and with less fatigue, they can complete additional cleaning tasks during a shift.

Ergonomic Machine Controls

CA60 24B control panelUsing large, comfortable palm activation paddles, the operator can easily control the machine. The operator does not have to control the machine using a handlebar, they simply place their hands on the paddle controls, pressing the buttons and guide the scrubber.

With palm activation, the operator will experience less fatigue and increased productivity.

Multiple Scrub Deck Sizes 

The CA60 can be purchased with either a 20-inch disc or BOOST® orbital deck, or with a 24-inch BOOST® orbital deck. 

The best deck size will depend on the size of your facility and the type of areas being cleaned. If you are looking to navigate into smaller areas, the smaller deck will be more productive than a larger deck. Having to maneuver a machine with a larger scrub deck in a small area or around furniture and fixtures can be more time consuming. 

Multiple Scrub Head Types 

This Clarke® CA60 automatic floor scrubber can be purchased with either a disc or orbital scrub head. 

Disc scrubbers utilize a round scrub deck and round floor pad or brush. They rotate the floor pad or brush at 150 rotations per minute.  

Orbital scrub heads “orbit” or move in fast, tight vibrations to clean the floor. They orbit at 2250 RPMs to clean the floor. Orbital scrubbing technology helps ensure uniform pad pressure in the front and back for even cleaning and reduced water and chemical consumption. 

BOOST® Technology 

This machine has the option to be purchased with BOOST®. As mentioned, BOOST® is orbital scrubbing technology. 

BOOST® technology applies up to 110 pounds of downward pressure for the most efficient one pass cleaning and the ability to remove floor finish with no chemicals.

Pro Tip: The BOOST® orbital machine can reduce water usage by up to 70% versus the conventional disc scrubber. 

Conventional Disc vs. Boost Technology

This orbital technology not only reduces water and chemical costs but maximizes worker productivity, lowering labor costs. 

BOOST® pads are rectangular in design. Rectangular pads extend reach along the walls and into corners. 

Vacuum Motor Protection 

For increased machine protection and maximum life expectancy, the Clarke CA60 is equipped with a floating ball to protect the vacuum motor from liquid and debris damage. 

On-Board Detergent Mixing System 

For facilities who do not have a chemical mixing system or would prefer to mix the chemicals in the machine, this scrubber can be equipped with an on-board detergent mixing system. 

On the control panel there is a dial which allows the operator to adjust the amount of detergent used during each procedure. 

Rubber Seal Around Tank 

CA60 recovery tankSealing the tank for maximum vacuum suction allowing this scrubber to fully remove liquid solution from the floor. Leaving the floor as clean and dry as possible is critical to occupant safety and floor appearance. 

The rubber seal snaps into place for easy removal for cleaning or replacement. 

Debris Capture 

This scrubber has a debris capture tray. The tray traps and collects large debris recovered by the squeegee to prevent frustrating clogged drain hoses. 

Simple Controls 

With a control panel mounted just below the handle, the operator can control all of the machine functions with the simple touch of a button. 

CA60 24B control panelAt their fingertips, they will have access to: 

  • Battery Indicator
  • Key Switch
  • Hour Meter
  • Water Flow Rate
  • Scrub Motor Power
  • Pad Release
  • Speed Control 
  • Vacuum 
  • Downward Pressure (BOOST® machines)

Pro Tip: With the CA60, the operator can push just one button to turn on the vacuum, the water, and the brush. On the BOOST® versions, the deck automatically lowers as well. 


Circuit Breaker

To protect the machine, there is a built-in circuit breaker. When too much power is being drawn, circuit breakers will trip to protect the motor and batteries.

Increased protection of the motor will help preserve the equipment and extend its useful life.

Rated as a top walk-behind scrubber of 2021, the Clarke® CA60 can be a productivity enhancing, time saving addition to your floor care program. 

Equipped with BOOST® technology, this machine is cost-effective and environmentally-friendly, reducing the amount of chemicals and water needed to clean.
