Design and Dock Architecture
The eufy C28 relies on a raised LiDAR turret rather than optical sensors, eliminating privacy concerns while avoiding the optical disorientation that camera-based units suffer on deep black rugs or unlit corridors. Underneath, an 11.02-inch cleaning path accommodates the DuoSpiral main brush and a 28cm HydroJet roller mop. Rather than dragging a static damp cloth, this roller spins at 270 RPM against a fixed scraper bar, fed by 24 internal water ports to deposit dirty moisture directly into an onboard recovery tank. The accompanying multi-function station handles auto-emptying, wet roller washing, wastewater extraction, and 50°C heated air drying to mitigate mildew. The dock utilizes standard disposable 3-liter dust bags rated for up to 75 days of dry debris. This automated upkeep trades quiet passive charging for periodic compressor whine during purge cycles and introduces regular consumable replacement expenses for the proprietary collection bags.
Vacuuming and Mopping Performance
While marketing emphasizes the 15,000 Pa motor rating, vacuum efficacy on soft flooring is governed primarily by mechanical agitation. The DuoSpiral brush design separates strands mechanically, showing negligible wrap against hair lengths up to 30 cm across repeated testing cycles. Suction steps up automatically on carpets, but the primary strength lies in preventing fine dust and pet fur from spooling around bearing caps. Hard-surface cleaning shows clear advancement over conventional dual-spinning discs. The constant scraper extraction prevents muddy slurry from being redeposited across tile grout. On mixed transitions, the chassis elevates the wet roller by 10.8mm to protect low-pile textiles. However, this clearance remains inadequate for medium-pile wool or shaggy rugs, which will inevitably make contact with the moist roller mechanism unless explicit keep-out boundaries are designated within the mobile companion app.
Value and Operating Economics
Priced at $499.99, the C28 operates in a highly contested segment where all-in-one maintenance stations were previously uncommon. Aggregated feedback reflects broad stability, averaging 4.3 out of 5 across nearly 60,000 reviews. At this price point, integrating both active roller washing and heated drying offers measurable functional parity with units historically retailing several hundred dollars higher. Buyers must, however, factor in the recurring financial impact of consumables. The 3L station bags require periodic replacement, and high-frequency mopping requires regular replenishment of clean water reservoirs alongside periodic descaling. The internal washable filter reduces one recurring expense, and running sound levels remain modest at 54.89 dB during vacuuming sweeps. For homes comprising mostly sealed wood, tile, and tightly woven area rugs, the unit presents strong economic rationale against competing base models requiring manual pad rinsing.
Limitations and Better Alternatives
Prospective buyers managing thick carpeting or cluttered low-profile spaces should exercise caution. With an obstacle avoidance threshold limited to items 3x3x3cm or larger, small rogue phone cables, stray socks, and thin wire hangers can stall the brush mechanism, requiring floor clearance before launching schedules. Furthermore, the 10.8mm roller lift mechanism is insufficient for plush carpets, where water transfer will occur regardless of the lift actuation. Homes featuring predominantly thick pile flooring would be better served by a dedicated high-clearance vacuum without wet apparatus, bypassing the bulk and moisture risks entirely. Similarly, owners averse to ongoing consumable costs may prefer bagless base stations, as the C28 permanently relies on sealed 3L disposable liners for its vacuum transfer routine. Verify clearance beneath low-slung credenzas, as the LiDAR turret increases overall chassis height.
