WHAT TO KNOW BEFORE ORDERING YOUR RT50D+
We want you to feel confident before you buy. Here are the key details about payment, shipping, delivery, warranty, parts, and support.
What payment methods do you accept?
We accept major online payment methods at checkout, including major credit cards, PayPal, Shop Pay, Apple Pay, Google Pay, Venmo, and Amazon Pay. Availability may vary depending on your device and checkout settings. Choose the option that works best for your business and confirm the order details before placing your RT50D+ order.
Is freight shipping included for the RT50D+?
Yes, the RT50D+ includes free freight shipping to the 48 contiguous states. Large floor scrubber machines usually ship by LTL freight, and delivery timing may vary by destination, inventory status, carrier pickup schedule, and local carrier availability. Please provide a valid street address and phone number at checkout so the freight carrier can coordinate delivery.
What type of delivery address do I need?
You need a valid street address where someone can receive and inspect a freight shipment during business hours. Freight delivery is standard curbside delivery, so the driver is not required to move the machine indoors. Before ordering, make sure your location can accept a commercial equipment freight delivery for a packaged machine weighing 364 lbs.
What should I check before signing for delivery?
Inspect the shipment before signing the delivery receipt. Check the pallet, carton, machine, and visible parts for damage or missing items, and note any issue on the delivery receipt before the driver leaves. If anything looks damaged, take photos and contact SUNMAX support within 24 hours with your order number so we can help with the freight claim process.
What if I am not sure the RT50D+ is the right floor scrubber for my facility?
Contact our team before ordering if you are not sure the RT50D+ is the right model. This commercial floor scrubber is built for hard floors, not carpet, and is best matched to facilities that need a 22-inch self-propelled floor scrubber with lithium battery power. Share your floor type, square footage, aisle space, cleaning schedule, and soil level so SUNMAX support can help confirm fit.
How does the RT50D+ warranty process work?
Eligible RT50D+ equipment is backed by SUNMAX warranty coverage for qualifying defects under normal use. Our U.S.-based support team can help diagnose the issue and coordinate the appropriate solution, which may include repair or replacement of qualifying non-wearable parts. Wear items, misuse, neglect, unauthorized modifications, improper maintenance, and damage outside normal use may not be covered.
Can I get replacement parts after purchase?
Yes, RT50 series replacement parts and accessories are available for ongoing maintenance. SUNMAX supports RT50 series parts categories such as batteries and chargers, controllers, hoses, motors, pads and brushes, squeegee parts, valves and filters, water tanks, and wheels. For the correct floor scrubber replacement parts, contact our team with your machine model, order number, and photos if needed.
What is your return policy for large equipment?
We offer a 30-day return window for eligible orders. Large commercial equipment returns must follow our return policy and may require prior authorization, proper packaging, inspection, freight coordination, and applicable return shipping or restocking fees. If you are unsure whether this is the right model, contact us before ordering so we can help confirm fit and reduce the chance of ordering the wrong machine.
