The iRobot Roomba 105 Vac + AutoEmpty Dock and the Roomba Max 705 Vac + AutoEmpty Dock are both vacuum-only robots with self-emptying docks. Per verified manufacturer specs, they share the same published dock behavior (self-emptying up to 75 days, allergen bags trapping particles as small as 0.7 microns) and similar robot footprints; they differ in navigation hardware, obstacle avoidance, claimed suction, and weight. Neither manufacturer publishes battery runtime, noise level, or warranty terms for either model in our verified data.

Where the Roomba Max 705 Vac is stronger (per verified specs)

Higher relative suction claim: iRobot claims 180X more power-lifting suction versus its Roomba 600-series baseline, against 70X for the Roomba 105 Vac. Both figures are relative marketing claims without a published Pascal value, so treat them as positioning, not measured performance.
AI obstacle avoidance: the Max 705 adds PrecisionVision AI obstacle recognition on top of ClearView Pro LiDAR; the Roomba 105 Vac's published record lists ClearView LiDAR only.
Allergen-bag wording: both docks trap particles down to 0.7 microns; the Max 705 record specifies an enclosed bag.

Where the Roomba 105 Vac is stronger (per verified specs)

Lighter robot: 6.24 lb vs 7.5 lb published robot weight — about 1.26 lb less to carry between floors.
Same published dock capability: identical 75-day self-empty interval and 0.7-micron filtration claim at a lower listed position in iRobot's lineup.

Which should you pick?

Per published specs only: if your home has furniture legs, cables, or pet obstacles you want the robot to recognize and avoid, the Max 705's PrecisionVision AI is the documented difference worth paying for. If you want the same self-emptying dock behavior and filtration claim in a lighter, cheaper package and can pre-tidy rooms, the Roomba 105 Vac covers the same core job. We do not perform hands-on cleaning tests, so we do not declare an overall winner.

Specifications neither model publishes (in our verified data)

We could not verify from sufficiently reliable sources for either robot: battery runtime, noise level, dustbin capacity, and warranty terms. Both models' suction figures are relative claims against iRobot's own Roomba 600 series rather than absolute Pascal values. Prices change frequently and are shown only where a dated source exists on the product pages.

How to read this comparison

This page compares manufacturer-published specifications only. We do not perform hands-on cleaning tests, so we do not declare an overall winner. Where a specification matters to you — for example AI obstacle avoidance or a lighter robot — prefer the model whose published claims meet your requirement, and treat unmatched relative suction figures as marketing claims rather than measured performance.

Sources and verification

All specifications above come from manufacturer product pages and specification sheets captured during our research pipeline and stored with per-field provenance in our database. Claims for both products were last verified on 2026-08-18. Values marked "not published in our data" were not found in the manufacturer documentation we reviewed; they may exist elsewhere.
