We tested Roborock’s new wet-dry vac and others on clay, glaze spills, and kiln dust — practical tips for home and small commercial studios.

Hook: The studio mess that keeps you from making

Clay on the floor, glaze splatters on the table, and a fine film of kiln dust that settles on every surface — if you make ceramics at home or run a small studio, you already know the cleanup eats time, risks your health, and stresses your landlord. You need a tool that makes fast work of mixed messes: wet spills, sticky raw clay, and respirable dust. Enter the recent buzz: Roborock’s new wet-dry vacuum (the Roborock F25 Ultra) — a compact, consumer-priced contender that promises pro-level cleanup. We tested it and a few other wet-dry vacs in real studio conditions to see how they actually handle clay, glaze spills, and kiln room dust.

The short answer — why this matters now (2026 context)

In 2026, more people are turning spare rooms, garages, and rented units into ceramics studios. Hybrid work, the maker-economy boom, and lower-cost kilns make small-scale pottery businesses common. That surge has two consequences: studios need compact, effective cleaning solutions, and regulators and health experts are increasingly focused on silica hazard controls and proper disposal of glaze washwater. Consumer devices like the Roborock F25 Ultra arriving from mainstream brands can be a game-changer if they meet three practical criteria: wet pickup safety, fine-dust containment (HEPA-level), and durable clog-resistant construction.

What we tested — studio-focused methodology

We ran a series of practical, repeatable tests in two environments: a home-studio (rental garage converted into a hobby space, ~12x12 ft) and a small commercial studio (shared makerspace with multiple kilns). Test goals were practical, not lab-grade: would a compact wet-dry vac clean the mess without damaging the unit, leaving unsafe dust, or creating a disposal problem?

Test matrix

Raw clay cleanup — 1 kg of wedged stoneware clay spread across sealed plywood and sealed concrete floors, fresh and partially dried.
Glaze spill — 2 L of typical water-based glaze (stirred with manganese and cobalt oxides at studio-typical concentrations), partly absorbed into a canvas dropcloth and puddled on concrete.
Kiln dust — fine, dry dust collected from a kiln room sweep (simulating respirable silica-containing dust).
Repeated cycles — multiple wet-dry transitions to stress test sealing, float valves, and filter saturation.

Units compared

Roborock F25 Ultra — the recently launched wet-dry model discussed in late 2025 and on sale in early 2026.
Two established shop-capacity wet-dry vacs (compact 10–15 L models used by hobbyists and small shops).
A rental-grade shop vac (higher capacity, commercial motor) as a control.

Results — real-world takeaways

Raw clay: suction, clogging, and flooring

Sticky clay is one of the toughest messes for any vacuum. In our home-studio tests:

The Roborock F25 Ultra cleared fresh clay puddles and higher-moisture lumps effectively on concrete. Its compact hose and nozzle handled detail work near pottery wheels better than the bulky rental shop vac.
Partially dried clay (10–30 minutes) began to string and compress in narrow hose bends on all compact units. The rental-grade vac showed fewer clogs because of its higher airflow and straight-access hose, but it was noisy and heavy.
Best practice: scoop heavy, tacky clay with a wide dustpan or flat shovel first, then vacuum the residue. The Roborock was excellent as the second-step tool — fast, maneuverable, and gentler on plywood floors.

Glaze spills: containment, filtration, and disposal

Glaze wash water can contain heavy metals and suspended solids. How you suck it up matters for safety and legal disposal.

The Roborock successfully cleared small puddles and absorbed glaze slurry when used with a separate recovery tank and dedicated wet-nozzle accessory. It’s important: many consumer wet-dry vacs separate solids and liquids into the same chamber — that makes cleanup harder and increases contamination risk.
For large glaze spills, pre-containment (using rags, absorbent pads) before vacuuming reduced filter saturation. Across all units, once the filter began showing glaze residue, suction dropped quickly.
Disposal note for renters: glaze slurry and washout is often considered hazardous waste depending on used pigments/oxides. Don’t dump concentrated glaze water down shared drains without checking local regulations. Use containers to solidify and dispose through municipal hazardous waste or follow studio rules.

Kiln dust: filtration and respiratory safety

Fine kiln dust is the most critical health hazard. Respirable crystalline silica can lead to silicosis. The vacuum’s filtration quality matters more here than raw suction.

The Roborock F25 Ultra performed well on visible dust and prevented visible dust clouds during pickup when used with its high-efficiency filter option. For very fine kiln dust, only vacuums with HEPA-grade filtration (or industrial equivalents) stopped airborne re-entrainment.
Neither compact consumer vacuums nor some 'wet-dry' models are rated to capture crystalline silica unless specifically marketed with HEPA/ H13–H14 filters. If your unit lacks certified HEPA, perform dust removal with PPE (NIOSH-rated respirator) and a HEPA vacuum.
Studio protocol: use a HEPA-filtered vacuum for kiln room cleaning, maintain negative air if possible, and always wear respiratory protection when sweeping or emptying dust collectors.

Safety checklist — what every pottery maker must know

Whether you’re a renter or run a small studio, follow these non-negotiables:

Use HEPA — For kiln dust, use vacuums with certified HEPA or H13/H14 filters. This is critical for respirable silica control (recommended by health agencies through the 2020s).
Separate liquids and solids — Avoid vacuums that mix hazardous glaze washwater with dry dust. Choose units with separate tanks or use containment methods.
Check float valves and motor protection — When picking up liquids, ensure the vacuum’s float/shut-off system is reliable to prevent motor damage.
Follow disposal rules — Know your local hazardous waste rules for glaze and oxides. As a renter, ask your landlord and local municipality before disposing of concentrated glaze water.
Noise and power — Rental agreements often limit noise; compact wet-dry vacs like the Roborock are quieter but still check your lease.
Hose access and attachments — Narrow hoses clog more easily with clay. Choose a unit with wide-diameter hoses and a range of nozzles for wheels, benches, and gutters.

Maintenance routine — keep your vac studio-ready

Longevity is a key concern for artists who buy compact vacs rather than commercial gear. Here’s a practical maintenance schedule:

After every wet use: Empty recovery tank, rinse and air-dry. Remove and wash pre-filters to prevent mold.
Weekly: Inspect main filter for glaze residue; replace or deep-clean as recommended by the manufacturer. Clean the hose with a dilute vinegar rinse if you pick up clay regularly.
Monthly: Check seals and float valves. Lubricate moving parts per manual. Test suction and listen for motor strain.
Every 6–12 months: Replace filters that show wear (paper filters, foam filters, or HEPA). For units used on kiln dust daily, replace HEPA annually or per manufacturer guidance.

Why the Roborock F25 Ultra could be a game-changer for studios

The Roborock F25 Ultra arrives at a pivotal moment: consumer brands are bringing compact, app-connected cleaning appliances to makers’ budgets. From our testing and market observation in early 2026, here’s what makes the F25 Ultra notable for ceramics studios:

Compact maneuverability — In home studios where space is tight, a compact form factor helps clean around wheels, under shelves, and in corners without moving heavy equipment.
Wet-dry flexibility — The ability to handle small glaze spills and raw clay residue with a wet-mode recovery tank is crucial for breaks in workflow.
Smart features — Many 2025–2026 consumer devices include app controls and scheduled maintenance alerts. These features help studio managers track filter replacement and maintenance across multiple units.
Cost-to-performance — With promotional launches (early 2026 saw some discounts on launch), the Roborock can undercut older shop-vac models while offering comparable everyday functionality for hobbyists and small studios.

Caveat: while the Roborock performed admirably for general studio hygiene in our hands-on tests, it must be paired with certified HEPA or dedicated industrial vacuums for consistent kiln dust control and silica mitigation in commercial workflows.

Case study: A renter’s garage studio

Sarah, a ceramics hobbyist renting a garage studio in 2026, needed a quiet, compact solution that wouldn’t violate her lease. She used the Roborock F25 Ultra for daily quick-tidies and kept a HEPA-certified shop vac for monthly kiln-room cleaning. Results:

Daily cleanup time dropped from 25 minutes to 7 minutes — more time at the wheel.
She avoided noisy rental-grade vacs that her landlord complained about.
When a glaze jar tipped, pre-absorbent pads + Roborock pickup prevented a larger spill and avoided sending glaze into the drainage system.

Buyers’ decision guide — pick the right vac for your studio

Pick based on your most common messes. Use this quick guide:

Mainly kiln dust? Prioritize HEPA-certified or industrial vacs designed for silica containment.
Mainly clay and small spills? Compact wet-dry vacs like the Roborock F25 Ultra or similar models are fast, quiet, and space-efficient.
Large commercial shop? Invest in a rental-grade shop vac with straight-hose geometry, large capacity, and certified filters.
Renter concerns? Choose quieter, smaller units; check water disposal rules with your landlord and local authority.

Practical accessories and upgrades to consider

HEPA filter upgrade — If your model supports it, add a certified HEPA or H13 filter for kiln dust.
Wide-diameter hose — Reduces clay clogs.
Dedicated wet recovery container — Makes glaze disposal safer and easier.
Pre-filter bags — Reduce downstream filter contamination and simplify disposal.
Noise-dampening mats — Help meet rental noise limits while operating vacuums early or late.

Future trends (2026 and beyond) — what to expect

Several trends in 2026 are shaping studio maintenance equipment:

Consumer-grade wet-dry crossover — Brands like Roborock are blurring the line between household appliances and light commercial tools, making studio-capable vacs cheaper and more compact.
Smarter maintenance — App notifications for filter changes and self-cleaning cycles will reduce downtime and unexpected repairs.
Regulatory tightening — Increased scrutiny on silica exposures and hazardous-waste disposal could raise the baseline for what constitutes a safe studio vacuum.
Modular accessories — Expect more interchangeable tanks and certified HEPA modules compatible with compact units, giving makers flexibility without buying separate machines.

Final verdict and actionable buyer's checklist

The Roborock F25 Ultra shows real promise for home-based potters and small studios: it’s compact, capable, and designed for the kind of mixed messes ceramics makers face every day. However, it is not a blanket replacement for certified industrial HEPA vacuums in kiln rooms. Use the Roborock (or similar compact wet-dry vacs) for daily clay cleanup and small glaze spills, and keep a HEPA-rated unit for dust control and kiln-room maintenance.

Studio vacuum quick checklist

Use the compact wet-dry vac for fresh clay, table spills, and routine tidies.
Always scoop heavy clay before vacuuming to avoid hose clogs.
For kiln dust, buy or rent a HEPA-certified vacuum and wear a NIOSH-approved respirator during cleanup.
Contain and properly dispose of glaze washwater — don’t dump hazardous slurry down shared drains.
Follow a maintenance schedule: empty tanks, wash pre-filters, replace HEPA filters as recommended.

Actionable takeaway: For most home and small commercial studios in 2026, a two-tier strategy—compact wet-dry vacuum (everyday) + HEPA-certified vacuum (kiln dust)—balances performance, cost, and safety.
