Taking everything that was great about the original but adding a new spray wand for pet anti-odour formula, the VAX Platinum SmartWash Pet-Design is a great carpet and upholstery cleaner for pet owners. Its smart automatic dosing and powerful performance makes sure that this deals with any stain with ease.


  • Separate detergent tank
  • Powerful cleaning
  • Useful collection of handheld tools


  • Loud


  • UKRRP: £345.99

Key Features

  • Cleaner typeThis is an upright carpet cleaner with additional handheld tools for spot cleaning.
  • DetergentUses a separate detergent tank, mixing with fresh water automatically to get the best results with the least wastage.


The original VAX Platinum SmartWash is one of the best and most powerful carpet cleaners that I’ve reviewed.

The new VAX Platinum SmartWash Pet-Design builds on this with a removable sprayer handle, designed to target pet messes with pet stain and odour-remover. This makes it ideal for homes with (messy) pets, but those without may prefer the standard version, which cleans regular stains just as well.

Design and features

  • Keeps detergent separate
  • Auto-doses
  • Removable spray handle for dealing with pet stains

As with the standard version, the VAX Platinum SmartWash Pet-Design is a beast of a carpet cleaner. At 1070 x 325 x 480mm and weighing 8.95kg, it’s a very large carpet cleaner, designed for the biggest jobs.

This model has three tanks. There’s the 3.5-litre clean water tank, which is simply lifted from the front of the carpet cleaner and is filled with warm water.

Next, is the 1.9-litre dirty water tank, which sits at the bottom. This has a float inside it that shuts off when the tank is full. I found, as on the standard model, that when this tank is almost full, knocking the machine can cause the float to close. Turning the VAX Platinum SmartWash Pet-Design off and then back on tends to clear this.

Even so, the disparity between the top and bottom tanks meant that I had to empty the bottom tank roughly twice for each full clean water tank.

The final tank is for concentrated detergent. Vax provides two 250ml bottles of its Platinum Antibacterial Carpet Cleaning solution in the box. It works out cheapest to replace this in bulk, with a 4.5-litre bottle costing £44.99.

Keeping the detergent separate from the water is a really good idea. As the VAX Platinum SmartWash Pet-Design automatically mixes the detergent with water as you clean, this setup meant that I only ever used the exact right amount of cleaning solution.

Once a clean has been completed, any unused detergent should be decanted back into a bottle, and the tank cleaned out.

The main difference between this model and the standard edition is that here, the handle lifts out. This handle takes a smaller tank, designed to hold the Vax Pet Stain & Odour remover (250ml is provided in the box). Replacements cost £13 for one-litre.

This tool is designed to tackle pet stains directly, neutralising odours, rather than masking them. As well as making your house smell nicer, this kind of treatment can help stop pets from messing in the same area again.

It runs on two AAA batteries (provided). Shooting out a stream of liquid, this tool makes it easier to target a pet stain than when using a traditional spray bottle.

Using the VAX Platinum SmartWash Pet-Design is beautifully simple. Just turn it on and push it forwards and the front lights up, telling you that water and detergent are being dispensed onto the carpet; pull the cleaner back, and it goes into dry mode, sucking up water.

I really like an auto-dosing machine, as it takes the guesswork out of how long to leave a trigger depressed for. The only other carpet cleaner that I’ve seen with this kind of tech is the Tineco Carpet One Pro, which also has a sensor that shows how clean the floor is. The Carpet One Pro is a lot more expensive than the VAX Platinum SmartWash Pet-Design, though.

Once I’d finished cleaning, the VAX Platinum SmartWash Pet-Design has a Dry only mode, which uses suction to pull water out of carpets, so that they dry naturally faster.

I found it best to keep going while I could see moisture being sucked up through the clear floor head.

Inside the floor head are two floor brushes, which have an antimicrobial coating that prevents anything nasty from growing on them after cleaning. It’s the same tech as used on the Vax ONEPWR Blade 5 cordless vacuum cleaner.

For spot cleaning, either to tackle a tough stain or for the likes of a sofa, there’s a 2.5m hose with a selection of attachments: the manual 2-in-1 antimicrobial wash tool (with a brush and a rubber pet tool), and the SpinScrub, which rotates automatically, agitating dirt.

All of the hand tools use a manual sprayer, so a stain can be thoroughly covered by cleaning detergent.

At the end of cleaning, everything needs to be cleaned up. Vax makes this easy, as the two brushes can be removed from the front for rinsing, allowing the entire floor head to be wiped clean.

I did find that carpet fibres could get trapped in the clear cover’s water channel, but a hot tap was always enough to rinse everything through. The dirty water tank is easy to wash out, too.


  • Tackles tough stains easily
  • Handheld tools give flexibility
  • Brings out the best in carpets

As with the VAX Platinum SmartWash, the Pet-Design version cleans brilliantly and easily. Using it on an old rug, which had become quite grubby, I ended up with two tanks of dark black water and a clean-looking and smelling carpet at the end.

I tackled my usual stains with this carpet cleaner. First, I went with dried-on mud on a carpet. Here, the VAX Platinum SmartWash Pet-Design made short work of the mess, with just a couple of sweeps needed to remove the dirt from the carpet and leave it completely clean. It’s impressive how fast this carpet cleaner works on regular mess.

Next, I moved on to the dried-on ketchup stain. Here, teh VAX Platinum SmartWash Pet-Design needed a few sweeps to get the mess out. At this point, the stain was largely gone, and I could have finished cleaning this way.

However, as I had the hand tools available, I used them to tackle this stain, spraying it until well covered and then leaving the detergent for a minute to do its magic. Using the SpinScrub tool, the stain was quickly removed, returning my carpet to its original condition.

I used a moisture sensor after cleaning the carpet, and detected humidity at 28% initially, dropping to just 21% after 20-minutes. At this rate, the carpet would have been dry in around an hour after cleaning, but it was only just damp-to-the-touch after cleaning.

I found the cleaner quite loud at 86.3dB. This certainly isn’t the kind of device that I’d want to use every day.
