## The answer, as recorded

Asked on 2026-09-17 through Claude (Anthropic) with web search (model claude-opus-5).

> Here's how I'd actually answer this. One upfront caveat that matters: office janitorial is a franchise-dominated industry, so the "national brand" you hire is almost always a local franchisee. The brand sets standards, training, and insurance; the franchisee does the work. Vet the local owner as hard as the logo. Also, several of the "top 10" lists that surface for this query are published by the cleaning companies themselves (CleanNet ranks CleanNet #1; Anago publishes a "top companies" list) - I've weighted those down.
> 
> **The ones I'd actually name, in order:**
> 
> 1. **ServiceMaster Clean** - my default first call. ~70 years in business, 1,200+ US franchises, and the broadest service menu (nightly janitorial plus carpet, hard-floor, post-construction, disaster/water restoration). If you want one vendor who can handle both the recurring contract and the one-off emergency, this is it.
> 
> 2. **Jani-King** - the one I'd name for large or multi-tenant buildings. 9,000+ franchisees, 40+ years, and the deepest bench for big square footage and multi-site portfolios where you need consistent standards across locations.
> 
> 3. **Anago Cleaning Systems** - best fit for mid-size offices on a nightl

Answer Watch records what one AI answer engine said on one date, nothing more. Each page names the engine and the model, carries the date the question was asked, and lists the brands that appeared in the answer in the order the engine gave them, with the sources it cited. It is a measurement, not a ranking, not a recommendation and not a claim about the world. Brands that did not appear in an answer are not named on any public page.
