3 vs 4 Gallon Scrubber Specs
Tank Capacity
The Yokoma model lists a 3-gallon tank capacity in its attributes, while the SUNMAX model is designated as a 4-gallon unit. The SUNMAX features a specific 3-gallon solution tank and a 4-gallon recovery tank. This configuration allows for a larger dirty water volume. The Yokoma data highlights an 8.2-gallon clean water tank and a 6.1-gallon dirty water tank in its features, despite the attribute label. You should check the specific tank requirements for your cleaning duration. The SUNMAX offers a dedicated larger recovery capacity in its primary spec sheet.
Cleaning Width
Cleaning width determines how much floor area you cover per pass. The SUNMAX machine has a 14-inch brush width and a 17.8-inch squeegee width. This compact size makes it easier to maneuver in smaller commercial spaces like offices or boutiques. The Yokoma model features a 16.3-inch brush width according to its title, with a 20-inch brush mentioned in features. A wider brush covers more ground quickly. If you need to clean large open areas efficiently, the wider Yokoma brush may reduce your total cleaning time.
Compatible Surface
Both machines are designed for hard floor surfaces in commercial environments. The SUNMAX is suitable for mirror tile, marble, epoxy, PVC, emery, terrazzo, and concrete floors. It also includes pads for buffing and polishing these surfaces. The Yokoma model lists car interiors as a compatible surface in its attributes, which is unusual for a floor scrubber. It is also intended for shopping malls, hotels, and factories. You should verify if the Yokoma’s car interior compatibility applies to its floor scrubbing function or if it is a data anomaly.
Special Feature
The SUNMAX includes a digital LCD display screen that shows machine working status and error codes. This feature helps with quick diagnosis and repair, minimizing downtime. It also comes with a 26.25-foot power cord for continuous operation. The Yokoma model features a lift handle with automatic scraper lift and soft silicone buffer wheels. These features protect the machine and walls during operation. The digital display on the SUNMAX provides more technical feedback for maintenance purposes.
Weight
Weight affects how easy the machine is to move and store. The SUNMAX weighs 116 pounds. The Yokoma model weighs 176 pounds. The lighter SUNMAX is easier to handle for daily maintenance tasks. The heavier Yokoma may offer more stability during aggressive scrubbing. You should consider the physical strength required to maneuver the machine. A lighter machine is generally easier to transport and store in tight spaces.
Which Floor Scrubber Fits Your Space
Small office or boutique owners
The SUNMAX model features a 14-inch cleaning width and compact dimensions of 27.6 inches by 18.2 inches. This narrow profile allows easy maneuvering in tight spaces like cafés or clinics. Its 4-gallon recovery tank handles daily maintenance without frequent emptying, while the corded power ensures uninterrupted operation during short cleaning sessions.
Large warehouse or factory operators
The Yokoma unit offers a 20-inch brush width and a 16.3-gallon total capacity with separate 8.2-gallon clean and 6.1-gallon dirty tanks. This large coverage reduces downtime on expansive concrete or epoxy floors. The commercial-grade design supports heavy-duty scrubbing and drying, making it ideal for factories or airports where speed and volume matter most.
Users needing floor polishing
The SUNMAX includes a red burnishing pad and holder alongside the standard disc brush. This versatility lets you switch from routine scrubbing to buffing and polishing mirror tile or marble surfaces. The included 17.8-inch squeegee and LCD display aid in maintaining a high-gloss finish, providing a complete care set for hard floor preservation.

Frequently asked questions
Which tank size is better for large commercial spaces?
A 4-gallon tank is generally better for larger areas. The SUNMAX model offers a 4-gallon capacity, which reduces the frequency of refilling and emptying. This is ideal for high-traffic zones where continuous operation is necessary without constant downtime for maintenance.
How does tank capacity affect cleaning time?
Larger tanks allow for longer cleaning sessions before you need to stop. The 4-gallon capacity in the SUNMAX unit supports extended use in medium-sized venues. In contrast, the 3-gallon tank in the Yokoma model may require more frequent pauses to manage solution levels.
Can I use a 3-gallon scrubber for small offices?
Yes, a 3-gallon scrubber works well for smaller spaces. The Yokoma unit is designed for commercial use and fits well in areas that do not require massive coverage. Its compact form factor allows for easier storage and handling in tighter office environments.
What is the difference between solution and recovery tanks?
Solution tanks hold clean cleaning fluid, while recovery tanks collect dirty water. The SUNMAX model separates these with a 3-gallon solution tank and a 4-gallon recovery tank. This split design helps manage fluid levels efficiently during the cleaning process for better results.
Is a wider cleaning width better for speed?
A wider cleaning width covers more floor area per pass. The SUNMAX model features a 14-inch cleaning width, which is suitable for tight commercial spaces. While the Yokoma model has a larger overall footprint, the specific cleaning width determines how quickly you cover the floor surface.
Do these machines work on all floor types?
These scrubbers are designed for hard, non-porous commercial floors. The SUNMAX model is explicitly noted for hard floors. The Yokoma model lists compatibility with car interiors, indicating versatility, but both are primarily intended for durable surfaces found in commercial settings rather than delicate carpets.
How much space do these machines need to operate?
You need enough room to maneuver the machine safely. The SUNMAX model measures 27.6 inches by 18.2 inches, making it compact for tight spaces. The Yokoma model is larger at 24.8 inches wide, requiring more open floor space for effective operation and turning.
