If you’re torn between the MUPEAK Brushless Cordless Power Washer and the Beiguoo Cordless Pressure Washer, you’re looking at two very similar battery-powered machines. Both pack brushless motors and dual batteries, but they differ in max pressure—1500 PSI for the MUPEAK versus 1450 PSI for the Beiguoo—and in how they’re built.
I’ve dug through the specs and customer feedback for both to help you decide which one fits your cleaning routine. The real trade-off here is between MUPEAK’s longer hose and multi-nozzle flexibility versus Beiguoo’s perfect 5-star rating and slightly more compact design. Stick around because I’m going to break down exactly who should buy which.

Individual Product Breakdown
I spent time digging through the specs, customer reviews, and real-world usability for both of these cordless washers. Here’s my honest take on each one to help you decide which fits your cleaning needs.
MUPEAK Brushless Cordless Power Washer
1500 PSI | 21V 4.0Ah x2 | 200-inch hose | 6-in-1 nozzle
No products found.
The MUPEAK is the more versatile option here, delivering a solid 1500 PSI from its brushless motor that the brand claims runs 40% more efficiently than traditional copper-core motors. I really like the 200-inch hose—that’s a huge reach advantage over the Beiguoo, letting you clean a full car side without moving the unit. The 6-in-1 quick-swap nozzle with 0°, 15°, 25°, 40°, wide fan, and shower spray gives you serious flexibility for everything from rinsing plants to blasting driveway grime. That said, its 3.4-star rating from 27 buyers tells me there might be some consistency issues, so it’s a bit of a gamble for the higher pressure.
✅ Pros
- 1500 PSI max pressure—highest of the two
- 200-inch hose for extended reach without moving the unit
- 6-in-1 nozzle gives you 6 spray patterns from laser jet to shower
- Two 21V 4.0Ah batteries included for longer runtime
❌ Cons
- Lower 3.4-star customer rating raises reliability concerns
- Heavier and bulkier at 15″L x 10″W x 5″H
Beiguoo Cordless Pressure Washer 1450PSI
1450 PSI | 400W brushless motor | 2x4000mAh batteries | 8″L x 6″W x 10″H
- Brushless Pure Copper Motor
- Dual Batteries for Longer Working Time
- 2 Power Level
The Beiguoo is the safer bet if you care about buyer confidence—it’s got a perfect 5.0-star rating from 16 reviews, which is rare for a new cordless washer. Its 400W brushless pure copper motor pushes out 1450 PSI, just slightly below the MUPEAK, but the compact 8″L x 6″W x 10″H frame makes it much easier to stash in a trunk or carry around. I appreciate that it has adjustable speed and dual 4000mAh batteries for extended runtimes, though the shorter hose and lack of a multi-nozzle setup mean you’ll be repositioning more often. This one feels purpose-built for quick, reliable jobs where you don’t want to fuss with attachments.
✅ Pros
- Perfect 5.0-star rating from 16 verified buyers
- Compact 8″L x 6″W x 10″H footprint for easy storage
- 400W brushless pure copper motor is built to last
- Speed adjustable for different cleaning tasks
❌ Cons
- Slightly lower 1450 PSI max pressure vs MUPEAK’s 1500
- No multi-nozzle included—you’ll need separate attachments
Which One Should You Buy?
Honestly, both of these brushless cordless washers will get your car or patio clean, but they cater to slightly different buyers. Your choice really comes down to whether you value maximum reach and spray flexibility or a compact, proven-reliable workhorse.
MUPEAK Brushless Cordless Power Washer is right for you if…
- You need to clean large vehicles or fences without constantly moving the unit thanks to that 200-inch hose.
- You want maximum spray versatility with the 6-in-1 nozzle covering 0°, 15°, 25°, 40°, wide fan, and shower patterns.
- You’re tackling tougher grime and want the higher 1500 PSI rating to blast through stubborn dirt.
Beiguoo Cordless Pressure Washer is right for you if…
- You want peace of mind from a perfect 5.0-star rating across 16 verified purchases—rare for a new cordless washer.
- You need something compact at 8″L x 6″W x 10″H that fits easily in a trunk, RV, or garage shelf.
- You prefer a straightforward 400W brushless pure copper motor with adjustable speed for controlled cleaning.
❌ Who Should Skip All of These?
If you’re cleaning large driveways, siding, or commercial spaces on a regular basis, neither of these battery-powered units will cut it. A corded electric or gas pressure washer with significantly higher PSI and continuous water supply is what you really need for those heavy-duty jobs.
For the typical homeowner who wants a portable, cordless option for weekend car washes and patio touch-ups, I’d lean toward the Beiguoo for its flawless track record, but if you need the extra reach and nozzle options, the MUPEAK is worth the gamble.
Frequently Asked Questions
Which is better for brushless motor performance: MUPEAK or Beiguoo?
For pure motor performance, I’d give the edge to the Beiguoo because it uses a 400W brushless pure copper motor, which is a more specific spec than MUPEAK’s vague claim of being “40% more efficient than traditional copper-core motors.” That said, the MUPEAK delivers a higher 1500 PSI versus Beiguoo’s 1450 PSI, so it technically outputs more pressure. For real-world reliability and a proven motor, the Beiguoo’s perfect 5.0-star rating from 16 buyers gives me more confidence.
Is the MUPEAK worth the extra pressure over the Beiguoo?
That 50 PSI difference between 1500 and 1450 is honestly negligible in real-world cleaning—you won’t feel it on a car or patio. What you actually get with the MUPEAK that’s worth more is the 200-inch hose and the 6-in-1 nozzle with six spray patterns, which makes it far more versatile. If those features matter to you, the MUPEAK is worth it; if you just want a solid washer, the Beiguoo’s 1450 PSI will handle 95% of the same jobs.
Which cordless washer has better battery life?
The MUPEAK comes with two 21V 4.0Ah lithium batteries, while the Beiguoo includes two 4000mAh batteries. On paper, those are essentially the same capacity—4.0Ah is equal to 4000mAh—so runtime should be comparable. Both include two batteries, so you can swap one out while the other charges, which is the real win here. I’d expect around 15-20 minutes of continuous use per battery on standard mode for both, though the MUPEAK’s higher pressure mode will drain faster.
Is the Beiguoo’s 5-star rating more trustworthy than the MUPEAK’s 3.4 stars?
I’d say yes, but with a caveat. The Beiguoo has a perfect 5.0 from 16 reviews, while the MUPEAK sits at 3.4 from 27 reviews—that’s a meaningful gap in buyer satisfaction. The downside is that 16 reviews is a small sample size, and the Beiguoo is new on Amazon, so it hasn’t been stress-tested by hundreds of buyers yet. Still, I’d rather trust a perfect score from 16 people than a middling score from 27.
Which one is more portable for camping or travel?
The Beiguoo wins this one hands down. It measures just 8″L x 6″W x 10″H, which is a compact cube that slips easily into a trunk or RV storage bay. The MUPEAK is bulkier at 15″L x 10″W x 5″H, and while it comes with a carrying case, it takes up noticeably more space. If portability is your top priority, go with the Beiguoo.
Can both washers handle car washing without damaging paint?
Yes, both are safe for car washing as long as you use the right settings. The MUPEAK gives you 3 speed modes including a gentle mode for rinsing and a turbo mode for tough grime, plus a 40° nozzle and shower spray for safe washing. The Beiguoo has adjustable speed control, so you can dial it down for paint-safe cleaning. Just avoid using the 0° laser jet on either washer for car paint—that’s for concrete and tough stains.
My Final Verdict
I’m giving the overall win to the Beiguoo Cordless Pressure Washer. Its perfect 5.0-star rating from 16 buyers, compact 8″L x 6″W x 10″H frame, and 400W brushless pure copper motor make it the smarter, safer choice for most people—even though the MUPEAK edges it out on paper with 1500 PSI and a 200-inch hose. The MUPEAK is the better pick if you need maximum reach and six spray patterns for varied cleaning tasks.
If you’re still on the fence, ask yourself this: do you want proven reliability in a tiny package, or do you need the extra versatility of a longer hose and multi-nozzle setup? For the vast majority of car, patio, and outdoor cleaning jobs, the Beiguoo’s 1450 PSI is more than enough—and that perfect rating gives me real confidence it won’t let you down.
Winner: Beiguoo Cordless Pressure Washer
- Brushless Pure Copper Motor
- Dual Batteries for Longer Working Time
- 2 Power Level
Perfect for anyone who wants a compact, reliable cordless washer with a flawless track record. The 400W brushless motor and 1450 PSI handle everyday cleaning with zero fuss.
