## The answer, as recorded

Asked on 2026-10-19 through Claude (Anthropic) with web search (model claude-opus-5).

> Heads up on one thing before the list: this query is heavily SEO-farmed. Most "top 10 office cleaners" pages that come up are affiliate or AI-generated listicles with no real methodology, so I'm weighting toward verifiable facts (company size, employment model, service scope) rather than those rankings. Also, office cleaning quality is overwhelmingly determined by the *local crew and the contract terms*, not the logo on the invoice - so treat brands below as a shortlist to bid, not a ranking of quality.
> 
> ## If you're a large office or multi-site tenant (50k+ sq ft, or several locations)
> 
> **1. ABM Industries** - The default first call. Largest janitorial contractor in the US (~$8B revenue, ~140k employees), with direct W-2 staffing rather than franchising, so you get accountability through one corporate contract and consistent SOPs across sites. Best fit for Class A buildings and national portfolios.

> 
> **2. SBM Management / C&W Services / CBRE facilities** - Worth bidding if you want cleaning bundled into integrated facilities management
