What the Hoover CleanSlate Plus Portable Carpet & Upholstery Spot Cleaner is
The Hoover CleanSlate Plus Portable Carpet & Upholstery Spot Cleaner is a compact, carryable carpet cleaner meant for spot work. Think spilled coffee on the carpet, a dirty patch on the stairs, or a couch cushion that needs more than a quick vacuum.
Unlike an upright carpet cleaner that you push across an entire room, a portable spot cleaner is all about targeted cleaning. You bring the machine to the mess, spray cleaning solution through the tool, scrub with the tool head, then extract the dirty water back into a separate tank.
This model is a value option for smaller homes and frequent small cleanups. The big practical benefit is that it is easier to store and easier to carry than a full-size carpet cleaner, so you are more likely to use it right when a mess happens.
Why it stands out
The CleanSlate Plus makes sense for shoppers who want a portable cleaner that will not become a hassle project. Its size and carry-friendly design are the point. If you live in a place with stairs, limited storage, or you just do not want to haul a heavy upright out of a closet, that convenience is what you are paying for.
The included tools are also genuinely practical. You get a wide-path tool that is 7 inches across for covering more area, a tight-spot crevice tool for corners and edges (like around sewn-in couch cushions), and a hose rinse tool that helps flush the hose after cleaning. That rinse tool is a small detail that can make ownership easier because it helps you clear out leftover grime in the system before you put it away.
It also uses a dual-tank setup, which is what you want in a spot cleaner. Clean water stays separate from dirty recovery water, so you are not reapplying the same murky solution back onto the fabric as you keep working.
What it is like to own
Day to day, a portable spot cleaner lives or dies on whether it is easy to grab, fill, and put away. The CleanSlate Plus is built around that routine. It is designed to be easy to store and easy to carry, including up stairs, which is exactly where a lot of carpet messes happen.
The wide-path tool is the one you will likely reach for on stairs and larger spots. A 7-inch head can cover a stair tread quickly, and it is also useful when a “spot” turns into a bigger patch. Just keep expectations realistic: you can clean a living room with it, but it is going to take time because you are working in smaller sections.
Cleanup is where the hose rinse tool earns its spot. After you finish, being able to flush the hose helps you avoid leaving residue sitting in the line. That can matter for smell and general grossness the next time you pull the machine out.
What to know before you buy
This is a spot cleaner, not a full-size carpet cleaner. The wide-path tool helps, but you are still cleaning with a handheld tool and a relatively narrow path. If your main goal is washing wall-to-wall carpet across multiple rooms, you will be happier with an upright carpet cleaner designed for that job.
Also keep “pet stain removal” expectations grounded. A portable cleaner can help with surface messes, but urine odor can soak into padding or even the subfloor. In those cases, you might need deeper remediation beyond what any surface extractor can do.
Finally, be careful with heated-cleaning claims in this category. Many machines are really designed around using warm tap water or maintaining warmth, not heating cold water like a kettle. The CleanSlate Plus is best thought of as a practical extractor for quick cleanups, not a magic reset button for every stain.
The specs that matter
You carry it to the mess and clean in small sections. It is ideal for spills, stairs, and upholstery, but slower for whole rooms.
Keeping clean and dirty water separate helps you avoid reapplying dirty solution as you keep cleaning.
A wider head covers stairs and larger spots faster than a tiny brush tool, even though it is still not an upright-sized cleaning path.
The wide tool speeds up coverage, the crevice tool gets into edges and seams, and the hose rinse tool helps you flush the system before storage.
More capacity can mean fewer refill trips in the middle of a job, which matters when you are cleaning multiple stair treads or several upholstery spots.
A lighter machine is easier to carry one-handed, especially up stairs. It also makes it more likely you will actually pull it out for quick messes.
Who this product fits
You live in a walk-up apartment and need something you will actually use
The Hoover CleanSlate Plus is built for grab-and-go spot cleaning. Its carry-friendly design and compact storage make it realistic to keep on hand and bring upstairs when a spill happens.
Your stairs get dirty faster than the rest of your place
The 7-inch wide-path tool is sized in a way that makes stair treads less annoying. You can cover more area per pass than you would with a tiny handheld brush head.
You want to clean couch cushions and tight seams
The tight-spot crevice tool is meant for edges and corners, like around cushions and seams where crumbs and grime collect. It is a better match for upholstery detail work than a wider head.
You hate storing a dirty machine
The hose rinse tool helps you flush the hose after cleaning, which can make the whole ownership experience cleaner and less smelly between uses.
What else to compare
If you like the idea of a portable spot cleaner but want a different emphasis, these are the closest alternatives to consider.
Hoover CleanSlate Plus Portable Carpet & Upholstery Spot Cleaner FAQ
Is the Hoover CleanSlate Plus good for whole-room carpet cleaning?
It can handle larger areas in a pinch, especially with the 7-inch wide-path tool, but it is fundamentally a spot cleaner. For whole rooms, a full-size upright carpet cleaner is usually faster and less tedious.
Does the Hoover CleanSlate Plus work on upholstery?
Yes. It is designed for carpet and upholstery spot cleaning, and it includes a tight-spot tool that is useful for seams, edges, and tight areas on furniture.
How do you keep a portable carpet cleaner from smelling between uses?
The big habit is rinsing out what you can after cleaning and not storing it with dirty water sitting inside. This model includes a hose rinse tool, which is meant to help flush residue out of the hose before you put it away.
Will a spot cleaner remove pet urine smell completely?
Sometimes it helps, but not always. If urine has soaked into carpet padding or the subfloor, surface cleaning alone may not solve the odor, even if the visible stain improves.
What does “heated cleaning” usually mean for carpet cleaners?
In this category, it often means the machine is designed to work with warm tap water or maintain warmth, not heat cold water like a boiler. Results still depend a lot on technique, solution, and how many extraction passes you do.
Should you buy the Hoover CleanSlate Plus Portable Carpet & Upholstery Spot Cleaner?
Buy the Hoover CleanSlate Plus Portable Carpet & Upholstery Spot Cleaner if you want an affordable, portable way to handle the messes that actually happen in real life: spills on carpet, dirty stairs, and upholstery touch-ups. The appeal is not fancy features. It is that it is easy to carry, easy to store, and comes with tools that make it easier to clean both wide areas and tight corners.
Skip it if your main goal is deep-cleaning whole rooms on a regular schedule. A portable spot cleaner can do that job slowly, but it is not what it is built for. For most renters and small-space shoppers who just want a reliable cleanup machine they will use, the CleanSlate Plus is a sensible buy.
