## The answer, as recorded

Asked on 2026-09-23 through Claude (Anthropic) with web search (model claude-opus-5).

> ## First, the thing that actually determines your outcome
> 
> Office janitorial is not a product you buy - it's a local crew you rent. Every "best commercial cleaning companies of 2026" list you'll find is either SEO content or published by one of the companies ranking itself #1 (CleanNet USA's list, for example, puts CleanNet USA at the top). The national brands below are almost all **franchise networks**: you sign with the brand, but a local franchisee does the work, and quality varies enormously between franchisees in the same metro. Pick the operator, not the logo.
> 
> That said, here's who I'd actually call, in order:
> 
> **1. ABM Industries** - The one non-franchise on this list. Publicly traded, directly employs its cleaners, and bundles janitorial with engineering, parking, and energy services. If you have multiple sites, a real facilities budget, or need one vendor accountable across a portfolio, start here. Direct employment means you're not gambling on a franchisee's hiring.
> 
> **2. SBM Management / Harvard Maintenance (regional enterprise players)** - Same model as ABM, directly employed labor, usually more attentive at the mid-market size where ABM treats you as a small account.

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.
