The Shark CarpetXpert EX151 pulls strong suction, particularly at the nozzle, and keeps maintenance simple with easy access to the brushroll and cleaning components. It does poorly on certain stains, peanut butter and tomato sauce among them. The small dirty water tank limits how much ground you cover, though the hose storage system and integrated spot cleaning tool give it more reach than competitors. Buyers who want a budget-friendly machine with good suction are the fit; anyone expecting heavy-duty stain removal is not.

Full review
Suction at the nozzle, not at the hose
Vacuum Wars measured unsealed suction at the nozzle as well above the category average, and that is the number the EX151's reputation rests on. Pushing the machine forward dispenses soap and water; pulling it back cuts the flow and maximises extraction, so the sequencing happens without the operator having to think about it. Sealed suction through the hose is the weaker half of the story, testing slightly below average, which matters if the plan is to do most of the work with attachments rather than the upright head. The 10-inch cleaning path is ordinary for the class, and the 25-foot cord reaches across a normal living room without an extension lead.
Peanut butter and tomato sauce defeat it
Stain performance is where the EX151 stops being impressive. Vacuum Wars rated it a below-average performer on tomato sauce, grape juice and especially peanut butter in the upright stain test, leaving darker residue than the category average after ten passes. Sugary, water-soluble messes go much faster, with ice cream and chocolate syrup clearing in fewer passes than average. The pattern is consistent enough to plan around: oily and sticky spills need pre-treatment or a different machine, and a household whose real problem is kitchen-adjacent rugs or pet accidents is buying the wrong cleaner. Suction and stain lifting are separate abilities, and this machine only has the first one.
A 28-ounce dirty tank caps every session
The dirty water tank holds 28 ounces, which is exceptionally small for an upright, and the clean tank is 0.6 gallons. Coverage works out to about 56 square feet per dirty tank, so a single medium bedroom usually means at least one trip to the sink partway through. Vacuum Wars flagged the same thing: frequent refills interrupt larger jobs, and the 5-foot hose is shorter than most, limiting reach on stairs and above-floor work. None of this changes how well the machine cleans the ground it does cover. It changes how long a whole-house session takes and how many times it stops.
Brushroll pops out without a screwdriver
Maintenance is genuinely easy, which is rarer in this category than it should be. A plastic cover over the brushroll pops open by hand and the brushroll lifts out without tools, so hair and fibre come off before they turn into a smell. The dirty water tank carries two filters rather than the usual one, catching more debris before it works its way further in. The hose stores on the body of the machine instead of in a box at the back of a cupboard, which is the difference between dealing with a spill immediately and leaving it. At 15.9 pounds the EX151 is light enough to carry upstairs one-handed.
Six months with the UK version
Hint of Helen lived with the UK-market version of this machine for six months and came away positive about the fundamentals: simple operation, carpets that smell clean afterwards, and a deep-clean mode that dispenses on the forward stroke and vacuums back on the pull. A separate dry-only mode runs suction without water to pull more moisture out at the end of a job. Three attachments ship in the box, a reversible bristle tool, an integrated crevice tool and a wide-path tool, and they handled sofas and headboards, though with noticeably more manual effort than the upright mode. Storage was easy enough that the machine stayed in regular use rather than getting shelved.
Strengths
- +Above average sealed suction at the hose and well above average unsealed suction at the nozzle
- +Brushroll is highly accessible and easily removable for cleaning
- +Hose stores on the carpet cleaner itself, which makes transitioning from upright cleaning to spot cleaning very easy
- +Cleaning and maintaining the cleaner head is very easy with accessible components
Watch-outs
- −Below average performer cleaning tomato sauce, grape juice, and especially peanut butter in upright stain test
- −Dirty water tank has exceptionally low capacity, which gives this cleaner a very small area of coverage before you need to empty this tank
How it compares
The Shark CarpetXpert EX151 offers better suction at the nozzle than the Bissell TurboClean Pet XL 3746 and has an integrated hose for easy spot cleaning, but it performs worse on tough stains like peanut butter compared to the Bissell Revolution HydroSteam 4120. It also has a smaller dirty water tank capacity than the Bissell Big Green Pet Pro 3288.
