## Verdict

Overpriced with minimal gains over the Combo 10 Max.

## For

- All-in-one design
- Highly visible on long-standing brand recognition
- Still surfaced by PCMag among its tested picks

## Against

- High price
- Marginal performance improvement
- Self-emptying dock often jams
- Brush roll fails after 12 months
- Sparse firmware updates

## Flagged as one to avoid

This product entered 4 of 7 runs as one buyers cross-shop but should not buy, rather than as a pick. It is published here rather than dropped.

## What this tier means

- F: Avoid. The evidence points you elsewhere.

## How to read this

- Each category is researched in four independent runs, one per lens (expert consensus, value, reliability, community pulse). Every run ranks a board of candidates that deliberately includes products buyers cross-shop but should avoid. Placements score on a ranked ladder (LP), and tiers are derived from LP, so no tier is ever assigned by hand.
- LP is this product's points on its own category ladder. It is comparable within a category and not across categories.
- Link status reports what our pre-publication link check found when it fetched the cited URL. It says nothing about the quality of the review.
- A citation with no usable link is listed rather than dropped, and is excluded from the counted total above.
