Founder Ryan Knoll told the Phoenix Business Brief that his Phoenix company adds a Zoom interview, a background check, a trial clean at his home and a 'grandma test' before cleaners reach clients.

Finding house cleaners good enough to send into clients' homes means screening about 300 applicants for every hire, Ryan Knoll, founder of the Phoenix cleaning company Tidy Casa, said on the Phoenix Business Brief podcast.
"We'll put out a job ad, we'll have about 300 people apply before we hire one," Knoll told host Bryan Hyde. Tidy Casa looks for attention to detail, customer service and punctuality, he said. "And man, they're unicorns."
The bar is high because the work is personal. "It's a very intimate service," Knoll said. "It's not like anything else because even if you're in a home hanging drywall, you're kind of— you're in and out, you're working in that one area."
Applicants who clear the online application get a Zoom interview focused on character, then a background check, he said. The final step is one he said many cleaning companies skip. "I actually have them clean my house. And that's probably the most important piece that I think a lot of cleaning companies miss," Knoll said. Only about "1% of people" make it that far, he said.
The standard comes from customers. Knoll said Tidy Casa asked every customer what would make it the best cleaning company, and the answers became its core values: "to be on time, to be thorough, and to be honest."
Complaints are rare and small, he said. "If we do 1,000 cleanings, we'll have, you know, 10 of them will, will say, ah, you missed a spot," Knoll said, usually something like a smudge on a microwave.
Weeding out weak hires took systems, he said. Cleaners who show up late are easy to spot, but "the okay-ish people who are kind of okay at cleaning were really, really hard to realize and recognize that they weren't doing a good job," Knoll said. Tidy Casa now tracks arrival times and customer satisfaction.
His final check is simple. "The ultimate test is the grandma test. Would I send this person to clean my grandma's house? If I wouldn't, they gotta go," Knoll said.
Keeping good cleaners matters because repeat clients drive the business. Tidy Casa backs its work with a "200% happiness guarantee," according to its website, and serves the Phoenix and Tucson areas.
