Bissell Big Green vs Hoover PowerScrub Deluxe: Which One Should You Buy?

Bissell big green vs hoover powerscrub deluxe: side by side

20 October 2026

Tank and power, as stated

The Big Green states a 1.75-gallon tank capacity with large clean and dirty water tanks for fewer trips to the sink, and a 12-amp power rating. It states cleaning on the forward and backward pass, which its listing says reduces cleaning time and dries faster than competitive rental cleaners. The PowerScrub Deluxe states dual tank technology but no amp rating in the shown text; its spec table lists 3.8 liters while its bullets state no tank size. For big rooms on one fill, the stated 1.75 gallons is the concrete tank figure here.

Brushes and drying

The Big Green states rotating DirtLifter power brushes that remove deep-down dirt. The PowerScrub Deluxe states five counter-rotating SpinScrub brushes that attack stains from multiple angles, plus HeatForce technology for faster drying. Both sides state multi-brush deep cleaning; the stated HeatForce drying is the PowerScrub Deluxe’s distinguishing line.

Reach and attachments

The PowerScrub Deluxe states an 8 ft hose with specialized pet and upholstery attachments for stairs, furniture, car interiors and corners. The Big Green states a 9 in long-reach hose with a 6 in tough stain tool and includes the Bissell 2x Professional Deep Cleaning formula. For stairs and car interiors, the stated 8 ft hose is the reach story; for formula in the box, the Big Green states the full Bissell 2x formula while the PowerScrub Deluxe states only a sample.

Match the machine to your home

Start with where the dirt lives. The Big Green states a 1.75-gallon tank capacity with large clean and dirty water tanks, and its listing says that means fewer trips to the sink. It states cleaning on the forward and backward pass, which the listing says reduces cleaning time, plus a 12-amp power rating. If your job is whole rooms and open carpeted areas, the stated 1.75 gallons is the figure that decides how often you refill, and the Big Green is the only side of this pair that states its tank figure outright.

The PowerScrub Deluxe answers a different floor plan: stairs, upholstery, pet accidents and car interiors. Its listing states an 8 ft hose with an upholstery tool for furniture, a pet tool for stubborn messes, and a crevice tool for tight spaces. It states five counter-rotating SpinScrub brushes that attack stains from multiple angles and HeatForce technology for faster drying. Where the Big Green is the stated 42-pound capacity pick for big open rooms, the PowerScrub Deluxe states 18.5 pounds with the hose-and-attachment setup built for corners and stairs.

Pet owners get a concrete contrast. The PowerScrub Deluxe states the pet tool by name alongside five counter-rotating brushes and faster drying via HeatForce, which the listing frames as professional-level stain removal at home without the cost of hiring out. The Big Green answers with the stated 6 in tough stain tool, the 9 in long-reach hose, and rotating DirtLifter power brushes that its listing says remove deep-down dirt. Both sides state deep cleaning claims; the distinguishing line is reach and attachment variety on the PowerScrub Deluxe against stated tank capacity and amps on the Big Green.

Formula, tanks and running costs

The box contents differ in a way that affects your first cleaning day. The Big Green states the Bissell 2x Professional Deep Cleaning formula included, and its title states the BISSELL PRO MAX formula included. The PowerScrub Deluxe states a 6 oz. Clean Plus 2X Carpet and Upholstery Cleaner sample, and its listing directs you to pair the machine with Hoover carpet shampoo solution, naming the Pet formula for pet messes and the Everyday solutions for everyday stains. That is a sample versus a full formula product in the box.

Both machines separate clean from dirty water. The PowerScrub Deluxe states dual tank technology with separate clean and dirty water tanks, and Auto Mix creates the stated perfect ratio of water to cleaning solution for consistent results every time. The Big Green states large capacity clean and dirty water tanks and notes that the chemical is packed into the tank. On the stated figures, the Big Green arrives with formula for a full clean while the PowerScrub Deluxe starts on a sample, so factor the ongoing solution purchases into your total cost.

Size, weight, storage and warranty

Weight and footprint are stated plainly and they diverge. The Big Green states 42 pounds at 20.5 in D x 11 in W x 42.25 in H. The PowerScrub Deluxe states 18.5 pounds at 21.9 in D x 14.6 in W x 23 in H. If the machine has to go upstairs, into a car for a detail, or up and down stairs regularly, the stated 18.5 pounds against the stated 42 pounds is a real deciding line.

Storage is also stated. The PowerScrub Deluxe lists a Mesh Tool Storage Bag and a storage mat among its included components, and its item type name states it comes with a storage mat. The Big Green lists Deep Cleaner as its included component with the stain tool and hose. Neither listing states a certification, so both warranty fields read only the warranty text.

On coverage, the Big Green states a Limited 5 Years warranty and the PowerScrub Deluxe states a 2-Year Limited Warranty. A few figures stay unclear: the PowerScrub Deluxe bullets state no tank size, though its spec table lists a 3.8 liters capacity figure, and its listing states no amp rating. The Big Green states rotating DirtLifter power brushes with no brush count. Where a listing leaves a figure unclear, we say so rather than declaring a winner on that spec.

Choose the Big Green if
