Shark 1171FK870 ION Robot side brushes, 4-pack compatibility

Identifiers to match

Manufacturer SKU: 1171FK870. No separate verified barcode is recorded. Match the exact robot code and printed part identifier; shape or color alone is not evidence.

How this part page is researched

Each model above has its own verdict, note, region scope and manufacturer URL. A Fits label means the manufacturer lists the relationship; it does not claim a VacPartFit physical test. Unknown is never converted into a compatibility recommendation.

Ordering checklist

1. Copy the robot model from its nameplate or app.
2. Match SKU 1171FK870 on the manufacturer page.
3. Read exclusions for Combo, Plus, Max, Ultra and regional variants.
4. For batteries or electrical parts, follow the manufacturer safety instructions.

Physical checks for this side brush

The attachment point matters more than the number of arms. Check whether the brush uses a screw or a push-fit hub, the shape of its center and the manufacturer's part identifier. Three-arm and five-arm brushes can look interchangeable while belonging to different drive modules. Keep any module-version caveat on the official listing with the fit decision.

With the robot powered down, inspect the user-removable brush for wrapped hair, damaged arms and a cracked hub. Use the removal method in the model manual. A push-fit brush must seat normally; a screw-fit brush should not require a substituted screw or extra force. A brush that still stalls after cleaning needs further manufacturer diagnosis rather than repeated replacement purchases.

An aftermarket seller may describe a longer bristle or softer material as an upgrade. Those descriptions do not establish fit or measured cleaning performance. Compare the mounting method and complete model list with the source below. VacPartFit has not physically tested this brush, and a Fits label applies to the manufacturer-listed item rather than every lookalike sold online.

Dimensions and generation changes

Exact dimensions are not recorded in the evidence dataset. The schematic is not to scale; check the original listing or ask the manufacturer before buying on measurements.

Use the grouped model verdicts to see the recorded generation boundaries. A missing sibling model stays unverified. A kit component without its own published item number is identified by the official bundle contents, not a made-up SKU.

Questions before checkout

Is this a barcode lookup?

A manufacturer SKU and a retail GTIN are different identifiers. Only separately sourced barcodes are accepted; a number printed in an Amazon title is not a verified barcode record.

Who verified these relationships?

The source and relationship review dates are available in each linked model-and-part section. Editorial responsibility rests with Feroz Sheikh. The catalog does not claim hands-on tests unless a page separately documents one.
