Eufy RoboVac G40 Smart Cleaning Robot Vacuum

The Eufy RoboVac G40 (eufy model T2255) is what budget-conscious buyers get at the entry level of the smart robot vacuum market: scheduled cleaning, app control and gyroscope pathfinding, with no map and no mop. It sits 72.5 mm tall, which eufy rounds to 2.85 inches, low enough for most sofas and bed frames. eufy quotes 55 dB in Standard mode, and its own comparison sheet lists the full span as 52 to 67 dB. This page is a compendium of eufy's documentation and owner reviews rather than a hands-on test; the robot in this house is a different brand.

One thing to know before reading further: as of October 2026 the G40 has quietly left eufy's own stores. The product page on eufy.com now redirects to the current robot vacuum collection, the Amazon listing shows no featured offer and only renewed units, and the G40+ with self-empty station is marked unavailable. eufy hasn't published an end-of-life notice, and the support page and manuals are still online, so treat this as a discontinued-in-practice model you buy second-hand or from leftover retail stock.

The RoboVac G40 targets a specific buyer: someone who wants scheduled daily cleaning without the complexity or cost of LiDAR-mapped navigation. It fills that role reliably, pairing BoostIQ Technology with gyroscope path logic for structured cleaning passes rather than the chaotic bounce-and-redirect behavior of cheaper entry-level models.

The Specs

The G40 runs on a brushless motor paired with a three-stage cleaning system: dual side brushes gather debris toward the center, a combo roller brush lifts it from the surface, and suction draws it into a 420 ml dustbin (eufy's comparison sheet gives 420 ml for the G40 and G40+, against 250 ml on the G40 Hybrid, which gives up bin space for a water tank). The triple-layer filtration setup, pre-filter, primary filter, and foam screen, traps allergens and fine dust rather than recirculating them back into the room.

Navigation relies on gyroscope-assisted path logic, producing more orderly rows than random-bounce systems but without the room-mapping precision of laser (LiDAR) units. That distinction is worth sitting with, because it is the one that decides whether you will be happy: gyroscope navigation has no persistent map, so it cannot be told to clean the kitchen, and it cannot resume where it left off with any certainty. Connectivity uses 2.4GHz Wi-Fi only, 5GHz routers require a separate 2.4GHz band active during initial pairing. The unit carries CE, FCC, and RoHS certifications confirming compliance with safety and electromagnetic standards.

Suction Power and Floor Performance

Standard mode handles everyday hardwood and tile maintenance effectively. When the G40 transitions onto low-pile carpet, BoostIQ automatically ramps up suction on detecting carpet, which is the feature that makes a 2,500Pa machine usable on rugs at all. Pickup percentages for this class get quoted freely and are worth ignoring unless the test surface, debris type and pass count come with them; none of those numbers here come from a controlled run, so none are printed.

Pet hair is the G40's most noted strength in owner reviews, and it is the single theme that recurs most often across them. The same reviews are equally consistent about the cost: the combo roller brush picks hair up well, then long hair wraps around it and has to come off with the included cutting tool every few cycles. That is not a defect of this model, it is what a bristle-and-blade roller does, and anyone whose reason for buying is a long-haired pet should budget the maintenance minutes rather than be surprised by them. Emptying the dustbin every session matters more than the spec sheet suggests, since a full bin costs suction before it costs anything else. eufy rates runtime at 100 minutes; that is the vendor's figure and no measurement here contradicts or confirms it.

Filtration and Maintenance

The high-performance filtration arrangement addresses a common budget vacuum weakness: debris recirculation. The triple-layer setup captures fine particulates that single-filter models push back into the air. Wash the foam filter monthly under running water and allow it to dry completely before reinserting, a damp filter degrades suction efficiency and risks motor damage over time. Replace the filter every 6 months under normal use, or every 3 months in high-shedding pet households.

Side brushes need weekly inspection and replacement every 3-4 months as bristles flatten. The cleaning tool included in the box handles hair removal from the roller brush without needing separate tools.

App Control and Voice Integration

The EufyHome app connects over 2.4GHz Wi-Fi and provides remote scheduling, suction mode selection, and cleaning history. Setup completes in under 10 minutes for most users. Schedule daily sessions by time and day of week, receive push notifications when cleaning finishes, and check battery status remotely from anywhere with a data connection.

Voice commands work reliably through Amazon Alexa and Google Assistant using start, stop, and return-to-dock instructions. Linking through either platform's native skill takes under two minutes. The G40 does not support Apple HomeKit and has no Matter protocol compatibility in this generation. For households built around Alexa or Google routines, running the vacuum when you leave for work, for example, the integration performs consistently in daily use without dropouts or reconnection issues.

What the G40 Handles Best

• Hardwood, laminate, and tile floors with everyday household debris
• Area rugs and low-pile carpets with automatic BoostIQ suction boost at transitions
• Pet hair accumulation on hard surfaces between weekly manual vacuuming sessions
• Homes under 100 square meters where a single charge cycle covers the full floor area
• Daily scheduled maintenance preventing buildup rather than deep-cleaning sessions

Setting It Up

Unboxing to first cleaning run takes under 15 minutes. Place the charging base against a flat wall with 1.5 meters clear on each side and at least 2 meters of open space in front, the G40 approaches the dock at an angle and needs that clearance to return reliably. Press the side brushes onto the spindles until they click, insert the dustbin, then fully charge before the first run (approximately 5-6 hours from empty). Pair the unit through the EufyHome app in-app setup flow, which walks through 2.4GHz Wi-Fi connection in around 3 minutes.

There are no boundary strips in the box, and the G40 doesn't read them: eufy's comparison sheet lists strip support only for the G40 Hybrid, and the base model has neither physical strips nor app no-go zones. Pet bowls, fragile floor decor and charging cables need a closed door or a physical barrier instead.

What Is in the Box

• RoboVac G40 unit
• Charging base and power adapter
• Multi-purpose cleaning tool
• Two spare side brushes
• Extra filter
• User manual (the self-empty station is a separate purchase, or the G40+ bundle)

Our Take

The Eufy RoboVac G40 is a focused daily maintenance tool rather than a premium cleaning system. It handles scheduled floor care in homes under 100 square meters with minimal setup friction, no subscription fees, and quiet operation that works around a normal household routine. Gyroscope navigation means no room map is generated, and no-go zones cannot be drawn through an app, for those capabilities, Eufy's L60 series represents the next step up at a higher price. What the G40 does offer is consistent, quiet daily sweeping that runs when scheduled and docks when done, without requiring ongoing configuration or maintenance attention.

Renters in one-bedroom apartments, households wanting automated maintenance between weekly manual sessions, and first-time robot vacuum buyers seeking proven technology without a steep learning curve will find this model fits well. The 12-month warranty is standard for this price range. Eufy's firmware update cadence on the G40 is conservative, updates arrive infrequently and focus on stability rather than introducing new feature risk. Long-term owners consistently report reliable brush and filter durability across months of regular use under typical home conditions. With the model gone from eufy's store, the practical question is spares: the G40 dust container is already listed as sold out on Anker's German accessories shop, while filters, brushes and the 2,600 mAh battery pack are still sold as shared parts across the G series.
