Scrubbing grout, tub corners, and sink rims by hand is tiring work, and it’s worse if your wrists, knees, or back complain. A cordless spin scrubber promises to do the scrubbing motion for you, so you only guide it.
Synoshi PRO is one of those scrubbers, sold online by a company called UAB Convenity. The offer page calls it “Transforming Cleaning into Pain-Free!” and says it can “Slash your cleaning time in half (and more!)” Spin scrubbers do take effort off your hands, but those are strong claims, so I checked what the base package includes, what it costs once you add the parts you’ll want, and how returns work.
For this Synoshi PRO review, I went through the offer page, its order, accessories, user guide and policy pages, the brand’s sales articles, Trustpilot, and BBB.
A cordless handheld spin scrubber with swap-in heads for grout, tubs, sinks and more. It saves wrist effort; budget for add-ons and read the return rules.
- Cordless with a 3-angle tilt head
- Up to 2 hours of battery, USB-C, per the brand
- Trustpilot 4.2 from 6,383 reviews
- 60-day returns, change of mind included
- Extension handle and many heads cost extra
- IPX5 doesn’t support the ‘submerged’ claim
- BBB shows an F for a Synoshi listing
- Return shipping is on you
Quick Verdict
Synoshi PRO makes sense if you want a light, cordless spin scrubber for bathrooms and kitchens and you’re fine buying the attachments you need separately. The brand lists IPX5 water resistance, a 3-angle tilt head, USB-C charging, and up to 2 hours of battery. Trustpilot is better than most I check, 4.2 from 6,383 reviews, but BBB shows an F for a Synoshi listing. The catches: the extension handle the FAQ pitches to seniors is a separate €24,95 add-on, and the original shipping isn’t refunded on a return.
What is Synoshi PRO?
Synoshi PRO is a cordless, handheld electric spin scrubber. A motor spins a brush head while you guide it over tile, grout, sinks, tubs, and other hard surfaces. The offer page lists a “Powerful High-Torque Motor,” a “Versatile 3-Angle Tilt,” and “Quick-Swap Heads.”
The brand’s FAQ says “The powerful motor provides 320RPM of scrubbing power” with “up to 2 hours of cleaning time.” It also says it comes “with specialized attachments designed for different surfaces,” though the page doesn’t say which are in the base package, and that “The adjustable speed settings give you complete control.”
The offer site’s About Us page lists the seller as “UAB Convenity,” with a Lithuanian VAT code. Orders, returns, and support go through that company.
What Comes in the Box
The offer page doesn’t list exact box contents for the base package, and that matters here. The accessories page sells many parts separately: an “Extension Handle,” a “Cone Brush Set,” a “Magic Eraser Bundle Set,” a “Round Brush Set,” a “Steel Brush Set,” a “Grout Cleaner Brush,” a “Precision Brush,” a “UV Light,” a “Soap Dispenser,” and a “Cleaning Solution.”
The main scrubber
The scrubber body has the motor, the battery, and a tilting neck. The brand’s photos show a round brush attached, and the charging cable is USB-C, per the offer page.
Brush heads
The user guide covers a round brush, a cone brush, a scouring pad, a Magic Eraser, and a steel brush. I couldn’t confirm which of these come with the base unit and which are add-ons, so check the order summary before paying.
Magic Eraser attachment
The user guide says the Magic Eraser “Works with water only” and is meant for scuff marks, crayon, and soap scum. It also warns, “Prolonged use may cause discoloration.” The accessories page sells it as a set for €14,95.
Charging cable
The offer page lists “USB-C Charging.” Trustpilot reviewer Richard Wells wrote in August 2026, “Needed better directions and I still don’t know how to charge it,” so keep the user guide handy.
Extension handle
This is the part I’d watch most. The FAQ says “The extended handle attachment allows cleaning without bending or stretching, making it perfect for seniors, people with arthritis, or anyone with mobility challenges.” But the accessories page sells the “Extension Handle” separately for €24,95. If that’s why you’re buying, add it to your budget.
Synoshi PRO Design Features
Here are the design points the brand lists, with a note where one needs care.
- 3-angle tilt: The brand says it helps you “clean under furniture, around fixtures, or reach high surfaces without awkward positioning.”
- Water resistance: The page says “IPX5 Waterproof Certified.” IPX5 is a splash and water-jet rating, not a rating for going under water, so I wouldn’t submerge it, even though the same line says it “will keep working after being submerged.”
- Motor: “320RPM,” per the FAQ, with “adjustable speed settings.”
- Battery: “Up To 2 Hours Of Battery,” with USB-C charging.
- Weight: The brand calls it a “Featherlight Design” but gives no weight.
- Heads: “Quick-Swap Heads,” with different brushes for different surfaces.
That’s a reasonable spec sheet for a handheld scrubber. The water rating wording is the one thing I’d read carefully.
Build Quality and Weight
The brand describes the build, but there’s no weight or material list, so this section sticks to what’s published and what buyers report.
Lightweight design
The offer page says “The ergonomic, lightweight construction prevents fatigue even during extended cleaning sessions.” No weight is listed, so I can’t compare it with rivals.
Grip
The brand calls the construction “ergonomic.” A handheld scrubber is usually easier on the wrists than hand scrubbing, since the motor does the back-and-forth.
Controls
The user guide describes an on/off button that cycles the speeds and a purple button that sets the angle. The FAQ mentions “adjustable speed settings,” and the guide gives a high or low speed for each brush.
Tilting neck
The “Secure Tilt Design” lets the head angle toward corners and floors. That’s useful for tubs and shower walls.
Durability reports
Trustpilot reviews are mixed on this. Two buyers reported the extension handle slipping off and the switch failing to turn off; their exact words are in the feedback section below.
What Owners Report Over Time
Trustpilot gives a useful long-term picture here, since Synoshi has thousands of reviews there.
Power and spin
The brand claims “320RPM.” Buyers disagree on whether that’s enough. A.d wrote in April 2026, “First, the motor power is extremely weak.” Many four- and five-star reviews praise the results, but I’d expect a light handheld unit to need several passes on heavy buildup.
Control on different surfaces
The user guide matters here. It says the round brush is for “Hard, flat surfaces only,” the cone brush for corners at “Low speed,” and the steel brush for “Metal, concrete, and tough outdoor materials only.” Its warnings keep coming back to one point: “Always test on a hidden area first if you’re unsure about the surface.”
Battery life and charging
Buyers who mention battery are mostly positive, saying a charge covers a couple of rooms; two of them are quoted in the feedback section below. The guide lists a full charge at 3.5 hours.
Magic Eraser over repeated use
The user guide says to “Replace when worn down.” Melamine sponges wear out, so plan on buying replacements if you use this one a lot.
Comfort during longer sessions
The brand pitches it to people with “Mobility issues,” “Arthritis,” and “Limited strength in arms, fingers and wrists.” A scrubber can take effort off your hands, but it isn’t a treatment for any condition. Bending to reach floors and tubs is still part of the job unless you buy the extension handle.
How it may change a cleaning routine
The brand claims “Save up to ¾ of every hour you’d spend cleaning.” It gives no study. I’d expect time savings on grout and tub corners, and less on general wiping.
How to Use Synoshi PRO, Step by Step
The user guide is clear and worth reading before the first clean. Here’s the routine it describes.
Step 1: Charge it fully
The guide says to “Open USB-C port cover and insert cable,” then “Charge until light turns from red to white (3.5 hours).” Close the port cover before you use it near water.
Step 2: Pick the right head
Use the round brush for flat tile and counters, the cone brush for corners and taps, the scouring pad for baked-on grease, and the steel brush outdoors only. The guide’s most repeated advice is to test a hidden spot first.
Step 3: Set the angle
To tilt the head, the guide says “Press and hold purple button,” then “Shift to 0°, 36° or 72° angle until you feel a click.” The guide doesn’t say which angle fits which job; I’d expect the 72° setting to suit floors and tub bottoms.
Step 4: Choose a speed
Pressing the power button cycles through the modes. The guide lists “High Speed: Blue light – for tough grime and stubborn dirt” and “Low Speed: White light – for gentle cleaning and longer battery life.” Press once more to turn it off. If it ever won’t switch off, as one Trustpilot reviewer reported, stop using it and contact support.
Step 5: Rinse and dry the heads
Most brushes can go in the dishwasher, separately from dishes, or be rinsed in warm water. The scouring pad is “Not dishwasher safe.” Let everything air dry so the bristles don’t stay damp.
Optional Add-Ons Worth Knowing About
Two add-ons on the accessories page change what the scrubber can do.
The Soap Dispenser “Applies soap or cleaning solution directly onto surfaces while you scrub.” The guide says to use “Dish soap, all-purpose cleaners, specialized cleaning solutions,” and to avoid “Thick pastes or gel-based cleaners,” which clog it.
The UV Light attachment “Reveals hidden dirt, stains, and organic materials that glow under 365nm UV light.” It doesn’t clean anything; it only shows you where to clean. The guide warns, “Never look directly into the UV light. Avoid direct contact with skin and eyes.” I’d keep it away from children.
Neither is essential. If you add anything, the extension handle saves the most bending.
Pros and Cons
The short version, from the brand’s pages and what buyers report:
Where Synoshi PRO Should Work Best
Based on the user guide and the brand’s own surface list, these are the jobs it’s built for.
- Tile and grout: the round brush for flat tile, the cone or grout brush for lines.
- Tubs and shower walls: the tilt neck helps reach curves.
- Sinks and taps: the cone brush for “around taps and drains,” per the guide.
- Pans, grills, and steel or enamel surfaces: the scouring pad for “baked-on food, grease buildup,” but not on glass or glass-ceramic cooktops.
- Outdoor grills and paving: the steel brush, outdoors only.
It’s less suited to delicate or high-gloss surfaces, where the guide warns against abrasive heads.
How Synoshi PRO Compares to Traditional Cleaning Tools
The offer page has its own comparison, which I’ve kept as the brand’s claims next to what’s realistic.
Comparison Chart
| Point | Synoshi PRO (brand claim) | Hand brushes and sponges |
| Effort | “Effortless cleaning” | Scrubbing by hand |
| Time | “Takes minutes” | Depends on the job |
| Tools needed | “1 tool,” though heads are swapped and some are sold separately | Several brushes and sponges |
| Chemicals | “Minimal chemicals needed” | Depends on the cleaner |
| Cost | Unit plus add-ons | A few dollars per brush |
| Power needed | Battery, USB-C charging | None |
Hand tools are cheap and never need charging. A spin scrubber mainly saves your wrists and arms on repetitive scrubbing.
The brand’s claim that it removes “invisible contaminants” or keeps a bathroom “Germ-Free” isn’t backed by any test I found. Scrubbing removes grime; disinfecting is a separate step with a disinfectant product used as its label directs.
The “1 tool” idea is also a stretch, since the accessories page sells ten separate add-ons. Still, for grout and tub corners, a spin head does the tiring part.
Is Synoshi PRO Good for Renters and Homeowners?
Move-out cleaning as a renter
Grout lines, tub edges, and stove tops are the spots that show at a move-out inspection. A scrubber with a cone brush makes those easier to reach. It won’t fix stains set into old grout, though.
Protecting home surfaces
Homeowners should follow the user guide’s surface limits. The steel brush is for “Metal, concrete, and tough outdoor materials only,” and the scouring pad should avoid “Glass, fine wood, or any delicate surfaces.” The wrong head on the wrong surface can scratch it.
Getting into corners
The brand’s main pitch is corners: “Synoshi was designed to get into these places.” The cone and precision brushes are the ones to use, and one of them may be an add-on.
Who Should Buy Synoshi PRO?
It suits people who clean bathrooms and kitchens often and want to spare their wrists and arms.
- People with tile and grout to keep up
- Anyone who finds hand scrubbing tiring, as long as they treat it as a tool, not a treatment
- Renters preparing for a move-out clean
- People who’ll also clean grills, pans, or outdoor items with the right head
Skip it if you mainly wipe counters, or if you need the extension handle and don’t want to pay extra for it.
Real User Feedback About Synoshi PRO
Every quote below is from Trustpilot, with the reviewer’s name and date.
Synoshi’s Trustpilot page, checked November 8, 2026, shows a TrustScore of 4.2 from 6,383 reviews: 49% five stars, 30% four stars, and 13% one star. The profile is claimed, and Trustpilot notes the company asks customers to review. BBB lists “Synoshi electric spin brush scrubber” in Cheektowaga, New York, with an F rating, not accredited. Its headquarters profile names a different company, so I’d read it carefully before ordering.
Two happy buyers, from Trustpilot:
Crystal Boyd wrote in November 2026, “the battery lasts long enough to get through both rooms.”
Mysia Haight wrote in July 2026, “The charge lasts a long time and changing the heads is a snap.”
And one with a suggestion:
Elinor Winterhalt wrote in August 2026, “Product improvement required to get the Synoshi extension handle to stay attached when the machine is in use.”
The complaints worth reading:
Joanna Morgan wrote in July 2026, “The Synoshi power scrubber will not turn off. Rather scary.” Theresa Perillo wrote in April 2026, “In approximately 6 weeks they billed my credit card for the second one.” That last one is a reason to check your order total and quantity before you pay.
Synoshi PRO Claims Vs What I Found
| Claim | What I found | Where I checked |
| “IPX5 Waterproof Certified” and “will keep working after being submerged” | IPX5 covers water jets, not submersion. I’d keep it out of standing water. | Offer page |
| “Keep Your Bathroom Germ-Free!” | No test shown. Scrubbing isn’t disinfecting. | Offer page |
| “Save up to ¾ of every hour you’d spend cleaning” | No study or method given. | Offer page |
| Extension handle “perfect for seniors” | Sold separately for €24,95 on the accessories page. | Offer FAQ, accessories page |
| “risk-free 60-day trial” | Returns need an RMA form and the original packaging, and “shipping costs are not refundable.” | Offer FAQ, return policy |
Pricing of Synoshi PRO
When I checked the order page on November 8, 2026, it showed euro prices, and its data says they were converted from US dollars. US prices and shipping may differ at checkout. The page listed a unit “price of € 71,99” before the discount.
- 1 unit: €35,95
- 2 units: €49,96
- 3 units: €69,96
- 4 units: €85,96, or €21,49 each
Standard shipping showed at €9,95. Add-ons are extra: the extension handle was €24,95, the cone brush set €19,99, and the Magic Eraser set €14,95.
So one scrubber with the handle and shipping comes to about €71 at those prices. Check the order summary, since an add-on or second unit changes the total quickly. I’d price a plain hand brush set too, just to know what the motor is costing you.
What to Check Before You Order
A short checklist, based on the pages above and the complaints buyers raise:
- Which brush heads are in the base package, and which are add-ons
- Whether you need the extension handle for floors and tubs
- The quantity and total on the order summary, since one buyer reports a second unit billed later
- The final currency and shipping charge at checkout
- That you’ll keep the box, since returns need the original packaging
None of these are deal-breakers, but each one affects your total or your return.
Where to Buy Synoshi PRO
My links go to the get-synoshi.com offer page. Its return policy says returns of items bought elsewhere follow “the seller’s policy,” so buying there keeps you on the 60-day terms below.
The return policy offers “a 60 day return policy,” including if “You have changed your mind and want to return a product.” But you must fill out a contact form, wait for an RMA form, and send it back with tracking. It says “Un-defective items must be returned in manufacturer’s condition, in original and undamaged packaging,” and “Please note that shipping costs are not refundable.” Keep the box. Buyers outside the US may also have local consumer rights on returns, so check those as well.
The shipping policy says orders are “typically processed within 1–2 business days.” Support phone numbers include a US line, +1 (218) 900-2005.
Frequently Asked Questions
These are the smaller questions I’d want answered, from what the brand publishes plus common sense.
Does Synoshi PRO Require Any Special Cleaning Products?
No. The brand says “Minimal chemicals needed,” and the Magic Eraser “Works with water only.” For heavy soap scum, your usual bathroom cleaner still helps; check that it’s safe for the surface.
Can Synoshi PRO Be Used on Vertical Surfaces Without Slipping?
Yes, on shower walls and tile. The tilt neck should help you keep the head flat against the wall. Use the speed the guide suggests for each brush.
Is Synoshi PRO Noisy During Operation?
The brand doesn’t give a noise level. Any motorized scrubber makes a motor hum, so I’d expect some noise.
How Much Pressure Do You Need to Apply While Cleaning?
Light pressure, guided by the brush. The user guide warns, “Don’t apply too much pressure on delicate surfaces.”
Can Multiple People Use the Same Synoshi PRO at Home?
Yes. I’d keep separate heads for toilets and kitchens, and rinse them after use; the guide says most brushes are “Dishwasher safe (wash separately from dishes).”
Is Synoshi PRO Waterproof?
The brand says “IPX5 Waterproof Certified.” That covers splashes and water jets. I wouldn’t drop it in a bucket.
Does the Extension Handle Come With It?
Not that I could confirm. The accessories page sells it separately for €24,95.
Final Verdict: Is Synoshi PRO Worth Buying?
Yes, if you want a light cordless scrubber for grout, tubs, and sinks, and you’ll budget for the heads and handle you need. I gave it 8.0 out of 10 overall for the design, the strong Trustpilot score, and a 60-day return window that includes change of mind. It isn’t higher because key add-ons cost extra, the water rating is oversold, BBB shows an F, and returns cost you shipping. If you order, check what’s in the package before you pay.
