Choosing between a 3 Gallon vs 9 Gallon floor scrubber depends on your facility size. Both the Yokoma and Moonchim models target commercial spaces. They share a commercial form factor and are built for hard surfaces. The main difference lies in tank capacity. The Yokoma offers a 3-gallon setup, while the Moonchim provides a 9-gallon system. This impacts how often you refill and empty the machine during large cleaning jobs.

Which one should you choose?
Choose Yokoma 16.3" Commercial Floor Scrubber if

- You are cleaning car interiors or smaller areas
- You prefer a more compact footprint
Choose Moonchim 9-Gallon Commercial Floor Scrubber if
- You clean large commercial floors like concrete or tile
- You want longer runtime without frequent refills
- You need a longer warranty for peace of mind
Verdict: The 3-gallon Yokoma suits smaller tasks or tighter spaces where weight matters. The 9-gallon Moonchim is better for large commercial floors that require longer runtime and larger capacity. Choose based on your square footage and surface type.
Tank Capacity and Cleaning Width
Tank Capacity
Tank capacity determines how long you can clean before refilling or emptying. The Yokoma model lists a 3 Gallon tank capacity in its attributes, though its features describe a dual tank system with 8.2 gallons of clean water and 6.1 gallons of dirty water. This discrepancy suggests the 3 Gallon figure may refer to a specific component or a smaller variant. The Moonchim model explicitly states a 9 Gallon tank capacity in both its title and attributes, with a 15.9-gallon solution tank mentioned in the title. If you need to cover large areas without frequent downtime, the Moonchim’s larger stated capacity offers a clear advantage for continuous operation.
Cleaning Width
Cleaning width affects how many passes you need to cover a floor. The Moonchim model provides a 21-inch cleaning width and a 32.6-inch suction width, allowing it to clean up to 32,000 square feet per hour. The Yokoma model features a 20-inch brush, which is slightly narrower. While both machines are commercial-grade, the Moonchim’s wider cleaning path means you will complete jobs faster in large spaces like warehouses or malls. The Yokoma’s 24.8-inch overall width is comparable, but the actual cleaning swath is smaller. For efficiency in wide-open areas, the wider coverage of the Moonchim is preferable.
Runtime
Runtime is critical for cordless operation in large facilities. The Moonchim model offers up to 5.5 hours of runtime on a single charge, which supports extended cleaning routes without interruption. The Yokoma model does not list a battery runtime in its provided data, so its operational duration remains unclear. If you are cleaning a large facility that requires several hours of continuous use, the Moonchim’s documented 5.5-hour runtime provides a significant practical advantage. You will know exactly how long the machine can work before needing to recharge, whereas the Yokoma’s capabilities in this area are not specified.
Weight and Maneuverability
Weight impacts how easily you can move and store the machine. The Yokoma model weighs 176 pounds, making it significantly lighter than the Moonchim model, which weighs 300 pounds. The lighter Yokoma may be easier to lift into storage or move around tight obstacles. The Moonchim’s heavier build, at 300 pounds, might offer more stability during heavy scrubbing but could be harder to maneuver in confined spaces. If you need to transport the machine frequently or store it in a small closet, the Yokoma’s lower weight is a practical benefit. For stability on large, flat floors, the Moonchim’s mass may be preferable.
Special Feature
Special features can simplify daily operation. The Yokoma model includes a lift handle that automatically lifts the rubber scraper off the ground when raised. This allows for easy entry into narrow spaces and protects the scraper during storage. The Moonchim model emphasizes easy operation with snap-on brushes and squeegees, requiring no tools. The Yokoma’s automatic scraper lift is a unique mechanical advantage for frequent transitions between cleaning and storage. The Moonchim’s tool-free assembly is convenient for setup. If you value automatic mechanical adjustments for the scraper, the Yokoma offers a distinct feature that streamlines the cleaning process.
Which Floor Scrubber Fits Your Needs
Small commercial spaces needing compact storage
The Yokoma model measures 24.8 inches wide and weighs 176 pounds, making it easier to maneuver in tighter areas. Its lift handle automatically raises the scraper for safe storage and entry into narrow spaces. This compact footprint suits venues with limited square footage where a larger machine would be cumbersome.
Large facilities requiring extended runtime
The Moonchim scrubber offers up to 5.5 hours of cordless runtime. This allows you to clean larger routes without dealing with cord drag or frequent downtime. The 500W brushless motor provides stable suction while operating below 55 dB. This quiet operation is ideal for busy commercial environments where noise matters.
Users prioritizing wide cleaning coverage
This model features a 21-inch cleaning width and a 32.6-inch suction width. It can clean up to 32,000 square feet per hour. The wider coverage means fewer passes are needed to clean large floors. This efficiency reduces labor time and makes it suitable for expansive commercial spaces like warehouses or large retail areas.
