Is this the right model for you?
Four exact-model points to review before opening the complete technical record.
Ideal for
Informational fit for mixed floors where automatic carpet detection and mop-pad lift are desired.
Why choose it
The AutoWash dock combines dust emptying, pad washing, drying, refreshing and dock self-cleaning.
Avoid it if this does not work for you
Measure practical clearance above the 106 mm robot height and reserve a stable hard-floor dock location.
Main limitation
The reviewed evidence does not establish a normalized threshold maximum or maximum area per floor.

What stands out
The useful differences
- The AutoWash dock combines dust emptying, pad washing, drying, refreshing and dock self-cleaning.
- Automatic carpet detection lifts the mop pads rather than forcing a vacuum-only route for every mixed-floor run.
- The exact Canadian black variant is G185020; the robot measures 357 × 351 × 106 mm and weighs 4.1 kg.
Decision checks
Before choosing this exact model
- Measure practical clearance above the 106 mm robot height and reserve a stable hard-floor dock location.
- The reviewed evidence does not establish a normalized threshold maximum or maximum area per floor.
- Confirm the exact G185020 package, seller and Canadian warranty before checkout.
Independent research record
Useful record with open questions
This assessment cross-checks the exact Canadian identity, official documentation, compatible parts and purchase constraints. A manufacturer claim, an independent measurement and an owner report are never presented as the same kind of evidence.
What is established
- 6 exact-model facts are published with their limits visible.
- 1 official source(s) can be opened from this record.
- An exact Canadian buying route is identified at Amazon.ca.
What remains uncertain
- RoboStead has not measured cleaning, navigation, noise, battery life or long-term reliability in its own laboratory.
- 6 purchase decision check(s) remain visible instead of being estimated.
- Repeated owner complaints are added only when the exact model and the pattern can be documented; isolated anecdotes are not converted into facts.
Ownership reality
- Weekly upkeep: Brush hair, sensors, mop pads and the dock tray determine how much work remains after automation.
- Recurring supplies: Check exact bags, filters, brushes, pads and detergent availability in Canada before comparing purchase prices.
- Long-term dependence: Battery access, dock pumps, app support and cloud-dependent features can matter more in year three than maximum suction on day one.
Outside evidence, clearly attributed
What external evidence adds to the official record
These observations come from the named publishers, not from a RoboStead hands-on test. We keep the useful result and its limitation together.
Vacuum Wars
Vacuum Wars measured above-average navigation and battery efficiency, and found that the LiDAR mapping, lifting mop pads and automated wash dock provide a coherent mixed-floor routine.
Its testing also produced very weak deep-carpet and pet-hair results, no meaningful small-object avoidance and an overly wet single mopping setting. Those limits matter more than the Roomba name.
Just a Dad Approved
This household review found the LiDAR map fast and accurate, the redesigned app easier to use and the vacuum-then-mop sequence sensible for hardwood maintenance.
The reviewer still judged the feature set modest for the price and reported that low objects can go undetected. Cables, toys and pet accidents should be removed before a scheduled run.
