The short answer
The SUNMAX RT50 lists at $2,499, while a new Tennant T300 typically runs $9,200–$11,130 depending on configuration — a gap of roughly $6,700–$8,600. On core specs, the RT50 actually has a wider 22-inch cleaning path versus the T300’s 20-inch, and larger tanks (13.2/14.5 gal vs. 11/14 gal). The Tennant runs quieter (58–65 dBA vs. RT50’s 68 dBA) and has a more established dealer network for on-site service. For most warehouses and facilities comfortable handling routine maintenance in-house, the RT50 delivers comparable or better core specs at roughly a quarter of the price.

Where the Tennant genuinely has an edge
Noise: the T300 runs about 10 dBA quieter, which matters if you’re cleaning during occupied hours in a hospital, school, or retail space. For after-hours warehouse work, this is less of a factor.
Dealer network: Tennant has an extensive third-party dealer network built up over decades, which can mean faster on-site service in some regions. SUNMAX ships parts directly from its Whittier, CA warehouse with U.S.-based phone support instead of a local service rep.
Onboard features: Tennant’s optional LCD Pro-Panel with programmable zone settings for different floor types is a genuinely useful feature for facilities that regularly switch between floor types — though many operators set a single mode and rarely change it.
Where the RT50 is comparable or ahead
Cleaning width and tank capacity: the RT50’s 22-inch path and larger tanks mean fewer passes and fewer refill stops over a full shift compared to the T300.
Lithium availability: SUNMAX offers a factory lithium option (RT50+) with a roughly 3.5-hour charge time versus 8 hours for lead-acid. Tennant’s lithium option is typically an aftermarket upgrade at added cost.
Parts cost: SUNMAX uses standard, non-proprietary components; a replacement squeegee typically costs less than the equivalent Tennant part, which is priced through the dealer network. Over several years of ownership, parts costs add up.
Build: both machines use rotationally-molded polyethylene bodies and quick-change brush systems, with a 2-year warranty on the RT50.
When the Tennant makes sense despite the price
If your facility operates during business hours around the public — hospitals, schools, retail — the T300’s lower noise level may be worth the premium. If you already rely on Tennant’s dealer network for service across multiple locations and want to standardize equipment, that consistency has value the spec sheet doesn’t capture. And if your team wants the programmable zone-settings panel for frequently changing floor types, that’s a genuine Tennant advantage.
Frequently asked questions
Is the Tennant T300 really worth $7,000+ more than the SUNMAX RT50?
On core cleaning specs — path width, tank capacity, runtime — the RT50 is comparable or ahead. The premium mainly buys quieter operation, a broader dealer network, and brand-name service infrastructure. Whether that’s worth the price difference depends on your facility’s noise sensitivity and service needs.
How much quieter is the Tennant T300?
About 10 dBA quieter (58–65 dBA vs. the RT50’s 68 dBA). That difference is noticeable in occupied spaces but less relevant for after-hours cleaning.
Can I get lithium batteries on either machine?
Yes on both, but differently: SUNMAX offers lithium as a factory option (RT50+) at a modest price increase. Tennant’s lithium option is typically an aftermarket upgrade at a higher added cost.
Which machine has cheaper replacement parts?
SUNMAX uses more standard, non-proprietary components, which tends to keep parts costs lower. Tennant parts are dealer-priced and can run higher for equivalent components like squeegee assemblies.
What’s the warranty on each machine?
SUNMAX backs the RT50 with a 2-year warranty on non-wearable parts. Tennant warranty terms vary by dealer and configuration — confirm directly with your dealer.
The bottom line
On specs alone, the SUNMAX RT50 matches or beats the Tennant T300 in cleaning width and tank capacity at roughly a quarter of the price. The T300’s advantages — quieter operation and an established dealer network — are real, but narrow enough that most warehouses, schools, and commercial facilities comfortable with U.S.-based phone support over a local dealer rep will get better value from the factory-direct RT50.
