So you're thinking about getting your first robot vacuum, and you've spotted two Eufy models that both look pretty great — but one costs noticeably less than the other. The question keeping you up at night: is the cheaper Eufy E25 truly 'good enough,' or will you regret not splurging for the Eufy C28 with its mopping feature? Let's settle this once and for all, because frankly, that's money in your pocket we're talking about.
The Eufy E25 is for anyone who wants a solid, no-fuss vacuum that focuses on one job done well — sucking up dirt. The Eufy C28 is for the person who dreams of a two-in-one machine that promises to handle both vacuuming and mopping, so you never have to think about your floors again.
In this post, we'll break down how these two robots actually perform in a real home, which one navigates your space smarter, how loud they get, and most importantly: whether that mopping feature is genuinely useful or just sounds good on paper.
Eufy is Anker's robot vacuum brand, known for making dependable, affordable options that don't require you to sell a kidney to afford. The E25 sits in the budget-friendly camp (think $200–$300 range), while the C28 bumps up the price considerably (closer to $500+) to add a mopping tank and combo functionality. Both use Eufy's solid navigation tech, but they're really aimed at different priorities.
Suction Power & Vacuum Performance
The E25 uses a 2000Pa motor (Pascal is the unit measuring suction strength — picture it as how hard the vacuum 'sucks' dirt up) that's totally adequate for hard floors and light carpet, especially if you don't have shedding pets. The C28 cranks up to 2500Pa, which feels like overkill for most homes, unless you've got multiple dogs; honestly, you'll barely notice the difference in real life, and your wallet will definitely notice the price bump.
Navigation & Mapping
Both robots use smart navigation to map your home, though the C28 has a slightly smarter system that builds more detailed maps. In practical terms, this means the C28 might plan a neater path across your living room, while the E25 takes a more 'wandering' approach — it still cleans your whole space, just not always in the tidiest order. If you've got a simple, open floor plan, you genuinely won't care; if your home is a maze of hallways and closed rooms, the C28 edges ahead.
Mopping: The Million-Dollar Question
Here's the honest truth: the C28's mopping feature is convenient, not magical. It can sweep away light dust and surface crumbs with a damp pad, and yes, it's nice to set it and forget it. But don't expect sparkling tile floors — it's more of a 'quick refresh' than a real mop. If you're someone who rarely mops anyway, or you have dark tile that shows every water streak, mopping might actually create extra work you don't want.
Noise Levels
The E25 runs at around 55 decibels (that's about as loud as a regular conversation), while the C28 sits around 60 decibels due to the extra motor for mopping. Neither will wake your sleeping toddler from across the house, but you'll definitely hear them doing their thing in the next room. The difference is small enough that noise alone shouldn't sway your decision.
App Control & Smart Features
Both robots connect to your phone via the Eufy app and let you schedule cleanings, set no-go zones (invisible boundaries that tell the robot 'don't go here'), and see where they've been. The apps are nearly identical and equally straightforward — no fancy AI features or weird complications. For a first-time vacuum buyer, both will feel like magic in your pocket.
Real-World Value & Total Cost
The E25 typically costs $200–$280, while the C28 runs $500–$600 depending on sales. That's a $250–$350 difference for a mopping feature you might use once a week, if that. Factor in replacement mop pads (which you'll buy every few months), and the C28 becomes the more expensive friend over time. Unless mopping is genuinely important to your life, the E25 is the smarter dollar move.
Durability & Support
Both come with Eufy's standard warranty and solid customer support. The E25 has fewer moving parts (no mopping motor), so there's marginally less that could break, but this difference is negligible. If something fails, Eufy will help you out; neither is known for reliability issues.
So, which one should you buy?
Here's the bottom line: the Eufy E25 is the robot vacuum that won't make you second-guess your purchase six months from now. It vacuums reliably, navigates your home intelligently, and costs about as much as a nice dinner for two. The C28 is a solid machine, but it's asking you to pay a significant premium for a mopping feature that — let's be real — you could handle with a $100 cordless mop on the weeks you actually feel like doing it. For someone picking their first robot vacuum, that extra cash is better spent on something else.
Trust your gut: if you're excited about the idea of mopping automation, go C28 and don't look back. But if you're honest with yourself that mopping isn't your life's passion, the E25 will make you feel like a smart shopper and keep your floors cleaner than they've been in years.
