Compare Shark CarpetXpert Upright Carpet, Area Rug & Upholstery Cleaner vs BISSELL Big Green Professional Carpet Cleaner

Innovation evidence centered on onboard hose convenience and pet-focused HairPro improvements over earlier models.

Innovation was a weak spot in one review, which said the machine’s only unusual trait was being larger and heavier than most competitors.

Tank feedback was mixed to negative: some reviewers found the smaller tank manageable, while others complained about frequent refills, low capacity, or added weight when full.

Water-tank performance was repeatedly praised for large capacity, removable/refill-friendly design, and long coverage between refills.

The lack of a built-in water heater was a drawback in one review, especially considering price.

The 7700 review described the heating element as useful for improving cleaning by raising hot tap-water temperature.

Durability confidence was limited by one reviewer’s concern that competing Bissell models might last longer.

Durability was a major strength in most reviews, especially rental-fleet build and tank-like construction, but one review cited leaking complaints.

Build quality evidence was split, with one reviewer praising a high-quality feel and another criticizing plastic-on-plastic construction.

Build quality was one of the clearest strengths, with reviewers citing rental-fleet toughness, long-lasting construction, and tank-like durability.

The liquid and solution system was divisive: several reviews praised the oxy or dual solution boost, while others found solution use high or saw little difference from Shark’s formula.

The liquid system stood out for efficient water use, removable/refillable tanks, visible solution status, and strong area coverage before refilling.

Hose length was mixed, with one reviewer impressed by it and another measuring it slightly shorter than average.

Hose length was praised by Vacuum Wars as Bissell’s longest hose, increasing reach for stairs, upholstery, and other above-floor tasks.

Weight feedback was mixed by model and context, with several reviewers finding it heavy or bulky but one noting it was lighter than larger competitors.

Weight was the clearest repeated drawback: reviewers consistently called the machine heavy, large, or difficult for stairs and some users.

Area rug handling was a major strength, with several reviewers reporting cleaner, fresher, or visibly improved rugs.

Area-rug handling was supported only by one 7700 review, which said best results seemed limited to small areas, bare floors, and area rugs.

Noise drew a clear complaint in one review, which found the Shark noticeably louder than a comparison vacuum.

Noise feedback was mixed: one technician found it very loud and advised earplugs for heavy use, while another owner considered it relatively quiet for its size.

Small-space suitability was mixed to weak: one reviewer liked the smaller footprint, while others warned it was bulky or clunky.

Small-space suitability was weak because reviewers emphasized the need for storage space and cautioned against the machine for users who struggle with its size and weight.

Heavy-duty suitability was mixed, with strong results on old grime and pet messes but weaker confidence for very caked-on stains or primary upright use.

Heavy-duty suitability was a standout theme: reviewers repeatedly framed the machine as a workhorse for large areas and deep cleaning.

Comparative performance was mixed: some reviews found it beat Bissell or HydroSteam models, while one lab-style review scored upright stain performance worse than average.

Comparative performance was strong, with reviewers saying it beat named rental-style competitors and lower-priced options for key cleaning tasks.

Storage was a repeated drawback, with reviewers calling the machine bulky and better suited to homes with more storage space.

Storage feedback was split: the fold-down handle helped storage, but the machine’s large body made it inconvenient for some users to store or use often.

Carpet hair pickup was mixed: the HairPro model handled ingrained dog hair well, while another reviewer saw clumps after skipping dry vacuuming.

One owner observed carpet pet-hair pickup during deep cleaning, tying hair removal to the brushroll and extraction performance.

Fresh spill and liquid pickup was generally strong, with praise for visible suction and fast removal, though one lab review found broader upright results uneven.

Fresh or wet stain pickup was praised in several tests, including fast grape-juice cleanup and strong wet-stain results.

Drying feedback was generally favorable but not unanimous, ranging from quick dry-to-touch results to average dryness in lab testing.

Drying performance was repeatedly praised, with reviewers saying it left carpets drier than competitors or helped carpets dry faster.

Tool transitions were generally praised, especially the quick hose access and simple attachment fit, though evidence is limited.

The hose/accessory changeover was described as clearly marked and simple, requiring only a quarter-turn connection process.

Overall opinion leaned strongly positive across most reviews, but one lab-style review was notably critical of upright carpet-cleaning performance.

Overall opinion was strongly positive across most reviews, with repeated best-in-class or highly recommended conclusions, plus one mixed consumer-review outlier.

Ease of use was one of the strongest themes, with reviewers repeatedly calling it easy, effective, agile, and intuitive.

Ease of use was strong where reviewers discussed push/pull cleaning, maneuverability, tank installation, and large-area coverage before refill stops.

The tool set was a major strength across reviews, with praise for the main brush, spot tools, pet tools, crevice access, and included accessories, aside from one mixed view of the StainStriker tool.

The included hose and tough stain/upholstery tools were usually viewed as useful, though one reviewer strongly disliked the included shampoo bottles.

Versatility was a strength, with reviewers praising use across rugs, carpets, upholstery, spot cleaning, and routine maintenance.

Versatility was praised for hose, attachments, above-floor uses, and multi-surface capability, though spot cleaning was only slightly above average in one test.

Most reviewers praised dried-on stain removal on wine, tea, mud, old upholstery stains, and pet messes, though test conditions varied.

Stain-removal performance was the strongest recurring theme, with reviewers praising dried-on, tough, vomit, tomato sauce, and other stain results.

Packaging feedback conflicted: one review praised eco-friendly packaging, while another noted substantial plastic waste.

Packaging received only light opinionated coverage, with one reviewer describing a colorful retail-style box full of advertising.

Warranty and support terms received a positive judgment in one review, which considered Shark’s shipping terms fair.

Warranty confidence and widely available parts supported reliability confidence in the reviews that discussed ownership support.

Maintenance was generally praised as easy, especially tanks, tools, brushroll access, and hair cage cleanup, though some reviews noted narrow grime areas or extra filter parts.

Maintenance was generally manageable, with easy tank and underbody cleanup, but brushroll removal requiring a screwdriver and interior wiping were drawbacks.

Floorhead design drew praise for working well and opening up for brushroll access and cleaning.

Floorhead feedback was mostly positive thanks to the large/aggressive brush and spring-loaded nozzle, but the 9-inch path was narrower than some competitors.

Emptying and mess control were praised repeatedly, especially the easy dirty-water tank, quick dumping, and separated hair cage.

The dirty-water tank earned strong marks in one test because it was easy to empty and clean through the large opening.

Reviewers consistently praised the machine’s suction and extraction power, although one lab-style review separated strong suction from weaker upright stain results.

Reviewers consistently praised suction at the floor head/nozzle, with repeated test evidence of class-leading extraction; the main caveat was weaker sealed suction at the hose in one test.

Upholstery and above-floor cleaning was mostly strong, with excellent spot-test performance and visible stain removal, though one reviewer found the StainStriker tool less powerful than the upright unit.

Above-floor and upholstery cleaning were considered useful and at least slightly above average, helped by the hose and tough stain/stair tool.

Value sentiment was mostly positive, especially at lower sale pricing, though premium pricing and model choice affected the conclusion.

Reviewers generally considered it worth the higher price because of performance, durability, and warranty support, while still repeatedly noting it is expensive.

Handling was generally positive despite size, with reviewers calling it maneuverable or vacuum-simple in use.

Handling feedback was mixed: one review called it easy to maneuver, while another said its heavy body was still felt during use.

Controls and interface were mixed: reviewers liked instructional stickers and automatic spray/extract behavior, but one found hose setup confusing.

Controls were viewed as simple and easy to operate, with one review noting the minimal on/off and trigger setup.

Pet-focused reviews were highly positive, citing pet mess pickup, odor control, hair handling, and suitability for homes with animals.

Pet-related cleanup evidence was strong, with one review highlighting urine-stain cleanup and another noting pickup of pet hair and stains from carpet.

One technician highlighted the spring-loaded/free-floating lower design as a rare design intended to accommodate higher-pile carpet.

Design impressions were mildly positive, with one reviewer describing the machine as fairly compact and sleek for a carpet cleaner.

Assembly and setup were widely praised as simple, quick, or straightforward, with only minor friction around hose installation.

High-pile or thicker-rug evidence was limited and negative, based on a cited customer complaint that it struggled on a thicker rug.

Hair and debris clog prevention was praised in HairPro reviews, with no-clog suction and no hair wrapping reported.

Cord length was positively reviewed in one source, where the extra-long cord made room navigation easier.

Cord management had limited positive evidence, with onboard storage keeping components together.

One review of the Big Green 7700 praised its filtration approach for containing dust and helping clean the air while cleaning floors.

Hair-removal channels were mixed: the hair cage was praised, but another reviewer struggled to remove clumps from a narrow cover.

Hair-wrap resistance was excellent in HairPro reviews, with reviewers reporting no hair caught and a self-cleaning brushroll preventing wrap.

Mopping or hard-floor washing support came from one 7700 review, which said the hard-floor tool did a good job on sealed surfaces.

Odor control evidence was positive, with reviewers noting fresh-smelling rugs and no lingering pet stains or odor.

Onboard storage was a standout convenience, with reviewers praising the hose, tools, and storage tray staying with the machine.

Ownership-cost evidence was negative because one reviewer expected the cleaning solution to run out quickly.

Self-cleaning evidence was mixed: the hose-cleaning function was praised, but another review said the machine could use a true self-clean function.

The hose and tough stain tool were repeatedly praised for making stair cleaning more practical.

Steam-cleaning feedback came from the 7700 review and was mixed: results ranged from adequate to very good, but slow operation was a caveat.

Streaking and residue feedback was mixed, with one reviewer seeing temporary streaks and another reporting remaining streaks in testing.

Attachment surface safety had limited but positive evidence from a reviewer who appreciated gentler silicone nubs on the handheld tool.

Wool compatibility was a clear limitation in one review, which said the cleaner was not suitable for wool carpets.
