Frequently Asked Questions
How much additional weight can I put on the Stonechat?
The Stonechat is designed for additional weight so that you can complete your job in less time.
Simply add 40lb horseshoe weights (one at a time) and monitor the on-board amperage meter to ensure you are not overloading the circuits. As long as you are operating within the “safe” limits you can add more weight to the machine.
The Stonechat accommodates up to ten 40lb horseshoe weights for a maximum of 400 lbs (181 kg) of additional weight.
How close can the Stonechat get to the wall?
The Stonechat’s 18″ grinding path still allows the operator to grind or polish up to ½” from the wall.
How do I downsize the Stonechat?
Like all Centaur floor machines, the Stonechat has a removable SplashGuard.
When you remove the SplashGuard you can now attach a 13″ Magpie or pad holder and use the machine to get into those hard to reach areas that need a “smaller” grinding/polishing path.
How do I use the Stonechat for countertops?
If you already own a Stonechat, get the Stonechat-Mini Conversion Kit (product #2C01700) to convert your Stonechat to a countertop polisher and grinder.
The conversion kit includes the Short Handle assembly, a 50′ cable, a 13″ flex SplashGuard and a 13″ Magpie with 6 cub discs.

Leading Institutions That Select Centaur Floor Machines










Versatile and a Time Saver
“I’ve been using Centaur floor machines for 15 years with great success. Attachments like the water tank and the 40lb weight makes the machine’s versatility quite impressive. The baseboard attachment (Scrub Jay) is phenomenal. As you know wax and liquids get splashed on the baseboards throughout the year and it is very time consuming to remove them by hand, but with this attachment, all that is required is to apply baseboard cleaner and go.”
—Dustin Chang, FCH Maintenance
