Commercial Cleaning Services: AI Visibility Market Discovery Index

Benchmark Summary

Jan-Pro leads the Commercial Cleaning Services benchmark in October 2026 with valid recommendation coverage of 55.8%, ahead of Stratus Building Solutions at 33.8%, a gap of 22.0 points. The largest coverage increase from the July 2026 baseline came from City Wide Facility Solutions, which rose to 15.8% in October 2026 from 4.6% in July 2026. The largest coverage decline came from Vanguard Cleaning Systems, which fell to 13.5% in October 2026 from 24.1% in July 2026.

October 2026 was a month of mixed movement. Most brands that posted significant changes relative to September 2026 moved upward, while the cumulative series from July 2026 shows several brands still below their baseline levels. ABM Industries, Anago Cleaning Systems, and ServiceMaster Clean each rose beyond normal month-to-month variation from September 2026, while Jan-Pro and Stratus Building Solutions also posted significant prior-month gains. City Wide Facility Solutions maintained its multi-month rise, classified as a significant riser with gains in each of the three months since July 2026.

The benchmark began with 800 prompt-surface observations in each month and produced 355 qualified observations after qualification.

Research Scope and Qualification

The public benchmark is narrower than the raw collection universe by design.

Brand-level percentages use the qualified observations as the public denominator, not the raw collection. See the AI Visibility Market Discovery Methodology.

Recommendation Placement Snapshot

Questions This Section Answers

• How do top-three and rank-one rates differ among Jan-Pro, Stratus Building Solutions, and Jani-King?
• What does a high top-three rate without a matching rank-one rate indicate?

Coverage alone does not show how prominently a brand is recommended. Among the leading brands, placement patterns differ.

Close coverage levels can still hide different first-position rates. Jan-Pro's 48.7% top-three rate in October 2026 sits alongside a 29.9% rank-one rate, while Jani-King's 25.1% top-three rate sits alongside a 7.6% rank-one rate.

Buyer-Intent Distribution

Questions This Section Answers

• Which buyer-intent classes do qualified observations currently cover?
• Why do Pricing & Value and Multi-Brand Comparison show zero qualified observations?

All qualified observations in October 2026 fell into the Brand Recommendation class, which represents direct requests for provider suggestions.

The current public series measures Brand Recommendation discovery and does not yet contain qualified observations in the Pricing & Value or Multi-Brand Comparison classes.

Evidence and Source Layer

The benchmark is built from prompt-level observations that retain the query, AI/search surface, answer, brand outcome, recommendation placement, sentiment, and where exposed, citations or attributable evidence sources. Source presence is evidence about the information environment. It is not automatically proof that the source caused the recommendation.

Scope Boundaries

This public benchmark does not measure market share, attributable sales, every possible AI response, organic-search ranking, social mention volume, private or sponsored channels, or causality from a metric movement alone.
