Roomba Replacement Parts Diagram: Component Names and Locations

A Roomba replacement parts diagram labels components by their physical location on the robot, providing a reference to identify the part you need. This identification step is separate from confirming that a specific replacement part fits a particular model or series – diagrams identify, they do not confirm fit. Even with correct names and positions, verification against your unit's revision may still be needed.

Without a location-based view, naming ambiguity between assemblies and sub-parts can lead to ordering the wrong part. A parts diagram helps by showing where each component sits within the robot, reducing confusion and the risk of ordering an assembly when only a sub-part is needed — for example, the cleaning head module versus its internal brush assembly. Matching a label to a physical position, such as the right wheel module versus the left wheel module, can help limit mistakes that come from verbal descriptions alone.

This page organizes identification information by diagram format and component groups, rather than listing every model or product. The following sections explain how to use these component groups and diagram formats for identification.

What a Roomba parts diagram helps you identify and what it does not confirm

A Roomba parts diagram identifies the names, locations, and assembly of components visible in the robot’s layout, but it does not confirm compatibility across different models or revisions.

When locating a specific brush or filter, the diagram’s callouts and labels reduce ambiguity. For example, the dual multi-surface rubber brushes appear in the bottom view with a clear label confirming their shape and mounting location.

In contrast, the same brush may have a different revision for a later model, meaning the diagram alone cannot confirm fit. This EAV chain marks the boundary: a part → its visible cues and location → the diagram label → clear identification, versus a part → model or revision constraint → fit not confirmed. To verify whether a specific component works with your Roomba’s model and revision, additional cross-referencing is required, such as visiting the Roomba replacement parts hub.

• Identifies
  • Component names and reference callouts for each visible part.
  • Exact locations, such as the position of dual brushes under the robot or the filter inside the bin.
  • Assembly relationships, for instance how the brush module attaches to the base.
• Does not confirm
  • Fit across different Roomba model numbers or hardware revisions; compatibility depends on the specific chassis design.
  • Necessity of replacement; the diagram does not indicate wear, performance decline, or malfunction.

This chart shows what a Roomba parts diagram helps identify and what it does not confirm.

Common Roomba Diagram Formats: Top View, Underside View, and Exploded Views

The diagram format determines what you can identify fastest and most reliably on a Roomba. These three formats—top view, underside view, and exploded view—each serve a different purpose when reading a Roomba parts diagram.

A parts diagram format defines the viewing perspective and level of detail used to present components. The table organizes each format's highlights, best use for identifying, and a common misread to avoid.

The image shows top, underside, and exploded views so you can match the format to your goal.

Format	Highlights	Best for identifying	Common misread to avoid
Top view	Cover, bin, faceplate, sensors, handle, filter access	User-accessible components and access points	Front-rear orientation if markers are missing
Underside view	Cleaning head, drive wheels, caster wheel, sensors, battery compartment	Floor-contact parts and drive system	Sensor positions if callouts are not aligned with orientation
Exploded view	Callout lines, assembly boundaries, sub-part relationships	Internal part hierarchy and assembly order	Confusing layered parts when assembly boundaries are not highlighted

Common misreads to watch for:

• Wrong orientation: Rotating the diagram without checking orientation markers can flip left/right or front/back labels, leading to incorrect part identification.
• Confusing assemblies: Parts that appear similar but belong to different sub-assemblies may be swapped if assembly boundaries are not clear on the diagram.
• Skipping legend: Ignoring the callout legend often causes misidentification of fastener types, part numbers, or reference symbols.

Recognizing these risks helps clarify what each diagram format reveals about specific component groups.

Top-view labels for controls, cover parts, and dust bin access points

Top-view labels on the cover typically indicate the button/control cluster and the dust bin release point. You can identify each by its position on the outer cover without opening the robot.

Underside layout for cleaning head modules, wheels, and sensors

The underside view allows locating and distinguishing the cleaning head module, wheel modules, and sensor windows without dismantling the robot. The cleaning head module occupies the center area with a distinct housing outline extending laterally. The wheel modules sit on either side of the cleaning head, each enclosed in a separate housing with visible wheel cutouts. The cliff sensor windows appear along the front edge and near the wheel housings as small rectangular or circular openings. Zone scanning — front for sensors, center for the cleaning head, and rear for wheel modules — often helps match each component to its label.

Exploded views, part numbers, and how assemblies are broken into sub-parts

An exploded view separates an assembly into its components while preserving spatial arrangement.

These cues help interpret callout lines, quantity markers, and assembly boundaries.

• Callout lines connect a part number or label to its specific component, clarifying which identifier goes with which piece.
• Quantity markers (often a number in parentheses) indicate how many copies of a given part are used in the assembly. This can help avoid under‑ or over‑ordering when the same part appears in multiple locations.
• Assembly boundaries (brackets, dashed lines, or grouped layouts) show which parts belong to a sub‑assembly, making it easier to distinguish what ships together as a unit versus separately.

A typical risk: a callout line that points to an assembly rather than a sub‑part can misdirect your search, leading you to order a whole upper‑level unit instead of the individual component you need. Part numbers on such diagrams may vary by series or source, so verify the label against your unit’s specific configuration.

Roomba component groups to locate quickly in a parts identification chart

Grouping components by functional area helps you locate parts faster in an identification chart. The chart groups each zone by location and function. Start by searching for the relevant group rather than scanning all part names.

Each zone maps to typical locations and common label terms from identification charts.

Component group	Where it appears	Common label words
Airflow/bin	Under the dustbin cover or near the rear of the robot	bin, filter, vent
Cleaning head	Underneath the robot, between the wheels	cleaning head, brush module, extractor
Mobility	Left and right wheel modules, front caster	wheel module, caster, drive wheel
Power/charging	Bottom charging contacts, battery compartment	battery, charging contacts, connector
Sensors	Front bumper, bottom drop sensors, cliff sensors	sensor, bumper, infrared

Use location or function to start:

• Start by location – look at the area of the robot where the part appears (top, bottom, front).
• Start by function – identify what the part does (clean, move, power, sense).

A common problem is mixing identification groups with part-type understanding. While component groups help you locate parts quickly, understanding parts types and what each one does is a separate step that involves matching shape, size, and material.

Reducing synonym confusion – for example, recognizing that “bin” and “dustbin” refer to the same zone – keeps your search efficient.

Dust bin airflow parts: filter, filter frame, seals, and vents

The airflow-path parts most commonly labeled around the bin area are the filter, filter frame, seals, and vents. Common label variants include:

• Filter: positioned inside the bin; often labeled as “dust bin filter” or “bin filter.”
• Filter frame: holds the filter in place; may appear as “filter holder,” “frame,” or “air filter holding frame.”
• Seals: gaskets between the frame and bin; usually labeled “rubber seal,” “gasket,” or “seal.”
• Vents: openings that allow air to exit; usually labeled “air vent,” “exhaust vent,” or “vent.”

The slot shape and size of the filter frame help identify its correct label.

Cleaning head modules: rollers, brush module parts, side brush, and covers

Cleaning head module labels are often grouped as assembly labels or sub-part labels to reduce wrong searches.

Assembly labels such as 'Cleaning Head Module' or 'Head Module Assembly' refer to the complete unit that includes the roller/brush, side brush, and cover. Sub-part labels such as 'roller brush', 'side brush', or 'cover' name each piece separately. Minimum differentiators like cover outline, roller placement, and mounting point orientation make the contrast between a module name (complete assembly) and an individual piece name (single component) clear.

Mobility assemblies: left and right wheel modules, caster wheel, and traction parts

Mobility diagrams for scooters and power chairs often lead to mismatched parts when left/right orientation is ignored. The wheel module on each side may appear symmetrical but often differs in mounting tab position, connector alignment, or cable routing, so verify labeling on the original assembly. The caster wheel placement is specific: front casters typically swivel freely, rear drive wheels remain fixed, and their orientation on the diagram should match the physical unit. Traction tread patterns serve as a visual label cue to distinguish left from right when markings are faded or absent. Confirm left/right placement against the actual chassis before searching for a replacement module.

Power and charging parts: battery placement, contacts, and connector orientation

Power-related labels like '+' and '-' markings, along with visual checks of battery placement, charging contacts, and connector orientation, help confirm correct identification.

Verifying these attributes improves identification confidence without implying fit compatibility. A mismatch risk arises when a battery pack's connector attribute—such as pin layout or tab shape—does not match the expected orientation. Connector orientation and contact arrangement may differ by model, so verify each attribute before assuming a match.

Sensing and navigation labels: bumpers, cliff sensors, and related housings

Sensing labels are designations on the physical housings that contain sensors and related components such as bumpers and cliff sensors on a robotic vacuum.

These labels typically appear on the front edge near the bumper assembly and near the underside windows that house the cliff sensor units. A label near the underside window often marks the position of each cliff sensor, helping identify the correct sensor housing for replacement. The exact arrangement of these sensor housings and labels can vary by series, so confirming the label position and housing shape against the specific model is recommended.

Part naming and labeling conventions that repeat across Roomba series

Naming patterns for Roomba parts repeat across series, but the same label wording does not guarantee the same physical fit. Interpreting labels correctly—rather than assuming compatibility—is the goal when using a parts diagram.

A naming convention is the system used to identify a part by module, assembly, or sub-part label. Common synonym clusters and search phrases help locate the correct part in a diagram. These examples map term variants to specific meanings and what to verify:

• Filter module – usually the complete filter assembly including frame – check series compatibility by model number prefix.
• Brush assembly – commonly the full roller unit with end caps – verify clip shape and length against diagram.
• Side brush – typically a sub-part that attaches to the brush motor – confirm bristle count and mounting type.
• Sensor array – often a module that includes multiple sensors – examine connector pin count and housing shape.
• Dust bin – assembly that varies by capacity and latch design – match bin height and release mechanism.
• Charging contacts – sub-part on the robot or dock – check contact spacing and spring tension.
• Same name, different shape – 'brush assembly' on one series may differ in roller material and diameter from the same term on another series.
• Different name, same location – 'side brush' on one diagram may be called 'edge sweeper' on another, but both occupy the same mounting point.

Use the diagram context—not just the label—to choose the right part designation.

This chart shows how Roomba part naming conventions work, what to verify for common parts, and warnings about label discrepancies.

Matching the diagram to your Roomba model and revision before ordering parts

A parts diagram must match your Roomba model, series, and revision before ordering, because a diagram that appears correct for the model family may not match the internal layout or connector arrangement used in your unit. Matching the diagram to your Roomba model and revision prevents near-miss orders. The annotated example below shows where model identifiers and key shape/connector cues usually appear. Without verifying these details, ordering from a diagram alone introduces fit risk; verify before ordering.

Common ordering errors happen when a part's visual outline matches the wrong series or an older revision without the same interface. The following minimum verification checks prevent near-matches.

• Locate the model number and series identifier on the product label – prevents ordering parts designed for a different generation.
• Note the revision code, often printed near the label or on the PCB – prevents mismatches when the same model series uses updated connectors.
• Examine the connector shape and pin layout on the part you need – prevents ordering a cosmetic match that lacks the correct interface.
• Compare the physical outline and mounting points to the diagram – prevents ordering a part that does not seat correctly.
• Check for orientation cues such as left/right wheel markings – prevents installing a mirrored part that conflicts with the chassis.

For example, a filter or brush module that looks identical across two series may use a different latch shape or connector pitch. Revisions within the same model line can change these details without altering the outward appearance. This near-match scenario often results in wrong orders when only the general diagram is used. For a full fit verification covering all part types, confirm compatibility before ordering.

Using a diagram to identify the correct replacement part from location-first clues

Start by identifying the part's physical location and attachment cues on the diagram before trying to match its name. The location-first approach uses mounting points and neighboring parts to narrow the search. Don't guess the name first—let the diagram's layout guide you.

Location-first identification uses mounting points, adjacent components, and visible attachment patterns to find the diagram callout that points to your part.

Use these identification-only steps to match the part to the diagram using location-first clues:

1. Note the general area where the part sits—look for surrounding components that appear in the same diagram section.
2. Check the part's mounting points: how many holes, their spacing, and whether they align with the diagram's fastener callouts.
3. Identify any neighboring parts that connect directly—wires, hoses, or mechanical links—and find them on the diagram first.
4. Trace the callout line from the part to its label; verify the label matches the observed markings (partial model numbers, brand symbols, or ratings).
5. Compare the attachment pattern—flange shape, bolt orientation, or connector type—with what the diagram shows.
6. Confirm the candidate part name by cross-referencing the callout number with the diagram's legend or parts list.

For each candidate, verify the observed location, the attachment or neighbor cue, the diagram callout, and the label before confirming the part. Once the candidate part is identified, refer to the general replacement steps for execution.

This chart shows the three-stage process for identifying a replacement part by using location clues from a diagram before matching names.

Identify by mounting points, covers, and neighboring parts before searching names

Observe mounting points, then the cover, then adjacent parts to match the diagram label.

1. Locate all mounting points — screws, clips, or slots that attach the part to the main assembly. Compare their number and pattern with the diagram to narrow down the possibilities.
2. Examine the cover: is it a protective cover, a decorative trim, or a functional module? Covers usually have a smooth finish and clip-on attachment, while functional modules usually include connectors or moving parts. Match the cover type to the labels shown in the diagram.
3. Identify adjacent parts — what components are directly next to the part you are inspecting? For example, if the part sits between a wheel and a sensor, that positional relationship helps confirm its name. Compare the relative position to the diagram's layout.
4. Caution: do not confuse a decorative cover with a functional module. A decorative cover typically has no electrical connections or moving parts and attaches only with clips or light screws. If you are unsure, verify by checking for wiring or moving components before finalizing the label.

If any of these do not match, stop and re‑examine before proceeding.

Confirm left vs right orientation and assembly-level vs sub-part replacement

Wrong matches often occur when a left-side part is swapped for a right-side part, or when an assembly-level module is confused with a sub-part inside it. These checks confirm the side and granularity level in the diagram.

• Left/right orientation depends on the view angle: a part shown from the front may reverse left and right compared to a rear view.
• Look for ‘LH’ (left-hand) or ‘RH’ (right-hand) labels; if the callout is missing, trace the cable routing or mounting holes to infer the side.
• When the same part number appears for both sides, orientation may not matter, but confirm that the diagram does not show a mirrored bracket or asymmetrical clip.

• An assembly-level module (e.g., a wheel module) includes multiple sub-parts such as the motor, gearbox, and wheel itself — replacing the whole module is different from swapping a single sub-part.
• Sub-part callouts in an exploded view usually point to individual components; if the callout line touches the outer housing, it likely refers to the assembly rather than the internal piece.
• Granularity cues come from the part description: words like ‘assembly,’ ‘module,’ or ‘unit’ indicate a higher-level part, while ‘gear,’ ‘belt,’ or ‘sensor’ indicate a sub-part.

Confirm both the side and assembly level before searching.

Use shape and connector differences to avoid near-matches across series

Eliminate near-matches by comparing shape and connector differences rather than relying solely on name similarity. These interface attributes distinguish one component from another.

• Tabs: Misaligned tabs can prevent proper seating → likely loose or non-functional assembly.
• Screw positions: Different screw hole locations can indicate an incompatible variant → likely mounting failure.
• Keying: Connector keying should match to avoid incorrect insertion → potential damage.
• Outline: The overall outline and connector shape can reveal series-specific differences → likely wrong part selection.

If these cues differ, don't assume fit.

Where Diagram Labels and Part Numbers Usually Come From and How They Map to Listings

Diagram labels and part numbers on parts diagrams typically originate from official manuals, exploded-view illustrations, and vendor diagrams. They represent the manufacturer’s identification for each component at the assembly level. However, the specific numbering system often varies by source, so numbers may differ between a printed manual and a third-party supplier diagram.

In an exploded view, a callout pairs a label with a part number to show which component belongs to a specific assembly. The label is usually a descriptive name, like 'brush motor', while the part number is the unique identifier for that item within the product line. When reading these diagrams, note the part name, the assembly it belongs to, and any series cues that help narrow the search to a specific model generation.

When mapping diagram labels and part numbers to listings, a listing may use its own internal coding instead of the original part number. In such cases, convert a diagram callout into a targeted search phrase using this simple mapping rule:

• Callout shows 'Motor Assembly - Part #12345' → search as 'brush motor assembly series-500'
• Callout shows 'Filter Cover - Part #67890' → search as 'filter cover roomba series-800'
• Callout shows 'Wheel Module - Part #11111' → search as 'wheel module assembly series-600'
• Callout shows 'Side Brush - Part #22222' → search as 'side brush assembly series-700'

Keep in mind that an assembly number on the diagram does not always match the sub‑part number you need; verify each callout against the diagram context before finalizing your search phrase.

This chart explains the origin of diagram labels and part numbers, the mapping rule to convert callouts into search phrases, and the verification step to ensure correct part identification.

Common diagram interpretation mistakes that lead to wrong-part orders

Wrong-part orders often result from misreading a parts diagram or mismatching the model number rather than from a simple shopping error. A quick checklist of common interpretation mistakes can prevent repeat ordering errors by catching them before checkout. Most errors are preventable with these checks.

The checklist below lists common diagram-reading mistakes, what they lead to, and how to avoid them.

• Wrong view orientation – Looking at a diagram from the wrong angle can cause you to misread which side a part belongs to, often leading to ordering a part for the opposite side. Prevent by confirming the view direction (top, bottom, left, right) before referencing callouts.
• Assembly vs. sub-part confusion – Confusing an assembly-level callout with an individual sub-part can result in ordering a larger unit when only a small component is needed. Prevent by checking the part number hierarchy; sub-parts typically have a deeper numbering level.
• Left/right swap – Mirror-image parts are frequently swapped when the diagram does not clearly indicate orientation, causing the wrong side part to arrive. Prevent by verifying the left/right or driver/passenger designator against your unit.
• Revision mismatch – Using a diagram from an older revision can lead to ordering parts that no longer fit the current model. This risk increases when multiple model years share similar diagrams. Prevent by matching the diagram revision or model year to your specific unit.
• Name similarity trap – Parts with similar names but different functions can be mistaken when scanning a BOM or list, causing the wrong component to be sourced. Prevent by cross-referencing the part number and description with the visual callout on the diagram.

When the symptom, not the diagram, drives the replacement decision, refer to what to replace when cleaning performance drops. In cases where error codes help narrow which labeled parts matter, see error codes and likely parts to replace. When two cues conflict, re-verify the model or revision before ordering.

This chart shows the main categories of diagram reading mistakes and the key preventive actions to avoid wrong-part orders.
