Testimonials
Let customers speak for us
from 192 reviewsWe received our Austrian crb and we're using since and it's a must have machine for every carpet cleaning business. Thanks for your fast shipment. You guys are awesome.
I got tired of underperforming machines marketed for residential use and purchased this unit because it was less than half the price of competitors with the same function/power. The unit arrived quickly and was easy to assemble. Day one I cleaned a wool lounge chair, mattress and two sofas and all came out looking good as new.
We've used this product for years when we started our services for VLM Carpet care. It's the best out there and the price is awesome with this company. Note, it does not ship from their office in Battle Creek. It ships from the manufacturer in South Carolina. No worries though, shipping was still lightning fast.
Awesome product! Thx for the Multi-Sprayer.
This is an amazing product! I had a ton of church pews to clean. This tool made it a snap!
Ps. I continue to love this product!
They were very prompt in responding to messages and getting shipping quotes (located outside of contiguous USA) Very good customer service. Highly Recommend.
Great service and on time deliveries
Highly recommend
I am a profesionnal carpet cleaner in Quebec Canada for many years.
I am very happy about my purchase and the good ans fast service I receive. Thank you so much because i save about $ 450.00 from the retail price in Canada. Will check to buy another one before spring.
I left a message requesting help with selecting CRB parts, and to verify repair methods. I was immediately contacted by a knowledgeable person who answered every question and totally made me feel like I mattered as a customer. I find that to be rare in recent years. Great service!
Great product to help work the Pre spray in for fantastic results.
I recieved my equipment in a timely matter. There was even a guy that reached out to me to make sure everything was going well withy order. I appreciate the great customer service
Great transaction. Great communication. I will do business with ya again when i get an OO this year.
Thanks
This machine is what every carpet cleaner should have in their toolbox. This is the best investment I have ever made, and I highly recommend it to fellow Carpet Cleaners.
I used this for the first time in a cottage bedroom, due to logistics and customer wanting immediate access to the room post clean. Vacuumed, pre sprayed and then scattered down the Dry Carpet Cleaning product. Thorough agitation using my CRB, followed by a clear up of the rest of my equipment back into the van, while the product worked its magic. Renovator trays on and collected up the dry compound, followed by a final vacuum and pile brush. Customer was delighted with the results "it looks like new". Happy customer, happy cleaner!
I absolutely love the machine. It's a huge step up from my sebo. But above all of that, the service I received from smart cleaning was world class and they went above and beyond to help me. Thanks guys!
