Carpet Extractor vs Shop Vac: Which One Should You Buy?

Carpet extractor vs shop vac: side by side

Specifications are manufacturer rated, as published on each listing and collected 20 October 2026. “Not stated” means the listing does not give the figure.

The extractor side

The sandia Spotter 50-1000 is the spec pick: roto-molded polyethylene tanks at 3 gallons of solution and 3 gallons of recovery, a 55 PSI solution pump (100 PSI available), a 2-stage Ametek vacuum motor at 804 watts and 100 CFM, 76 inches of lift and 115 volt power. No warranty term is stated. The Bissell BigGreen BG10 is the commercial pick: a deep-cleaning 2-motor extractor with a flow indicator that monitors water and solution levels, a large-capacity clean water tank that removes for filling, edge-to-edge suction and two large tanks. No warranty term is stated.

The shop vac side

The STANLEY SL18115P is the capacity pick: 5 gallons, a 4 peak HP motor at 85 CFM, blower 3-in-1 functions, a rear blower port, a 10-foot cord with built-in wrap and swiveling casters. The accessories include a 1-1/4 inch by 5-foot hose, two extension wands, a crevice nozzle, a gulper nozzle, a floor brush, a foam filter, a cloth bag with clamp ring and a dust bag. A 1-year limited warranty is stated. The VEVOR is the power pick: 4 gallons, a 5.0 peak HP motor at 65 CFM, portable 3-in-1 wet/dry vacuum and blower with filter, hose and attachments. No warranty term is stated.

Example products

How we scored them

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

Washing vs vacuuming

The extractor side sprays and recovers: the sandia states a 55 PSI solution pump and a 76-inch lift recovery; the Bissell states a flow indicator and edge-to-edge suction. The shop vac side moves air and debris: the STANLEY states 85 CFM and the VEVOR states 65 CFM, both with blower functions. An extractor does not replace a shop vac for dry debris, and a shop vac does not wash carpet. The listings agree on the split.

Tanks and capacity

The extractors carry two tanks each: the sandia states 3-gallon solution and 3-gallon recovery; the Bissell states two large tanks with a removable clean-water tank. The shop vacs carry one: the STANLEY states 5 gallons and the VEVOR states 4 gallons. For whole-car interiors, the extractor’s separate solution and recovery tanks are the design answer; for garage cleanup, the shop vac’s single big tank is.

Airflow and lift

The sandia states 100 CFM with 76 inches of lift on a 2-stage Ametek motor. The STANLEY states 85 CFM on a 4 peak HP motor. The VEVOR states 65 CFM on a 5.0 peak HP motor. The Bissell states no CFM figure, only edge-to-edge suction. Peak HP and CFM do not move together here: compare the airflow figures, not the motor labels.

Warranty

The STANLEY states a 1-year limited warranty. The sandia, the Bissell and the VEVOR state no warranty term.

The pump question

Only the sandia states a solution pump: 55 PSI with 100 PSI available. The Bissell states no pump figure, only the flow indicator and edge-to-edge suction. The shop vacs state no pump at all, because they are not washers. If the job is pre-treating stains, the stated pump is the figure that matters; the sandia is the only listing here that names one.

Matching the machine to the job

Start from the surface. For carpeted car interiors and upholstery that need washing, the extractor side is the answer: the sandia states 3-gallon solution and 3-gallon recovery tanks with a 55 PSI solution pump, so it lays down and lifts out cleaning solution in one pass. The Bissell states two large tanks with a 3.5-gallon capacity and a removable clean-water tank for the same kind of work. For dry garage debris, sawdust and water pickup without washing, the shop vac side fits: the STANLEY states a 5-gallon tank and the VEVOR states a 4-gallon tank, both single-tank designs that hold more dry waste per emptying.

Then weigh airflow against noise. The sandia states 100 CFM with 76 inches of lift on a 2-stage Ametek motor, the STANLEY states 85 CFM on a 4 peak HP motor, and the VEVOR states 65 CFM on a 5.0 peak HP motor. The STANLEY states 80 dB and the VEVOR states 77 dB, while the extractors state no noise figure at all. If the machine will run in a shared garage or near the house, the stated decibels are the tiebreaker the spec sheets give you; if it runs in a detached shop, airflow and tank size matter more. Only the STANLEY states a warranty at 1 year limited, so factor that into a long-horizon buy.

What the listings leave out

The STANLEY states an 80 dB noise level and the VEVOR states 77 dB, while the VEVOR also claims quiet operation. The extractors state no noise figure. The Bissell states a 3.5-gallon capacity with two large tanks, but no CFM figure. The sandia states the most complete spec sheet here: tanks, pump, motor, CFM, lift and voltage. When a listing omits a figure, that is a reason to treat it as unclear, not as a win for the other side.

Frequently Asked Questions

Which side deep-cleans carpet?

The extractor side: the sandia sprays solution at 55 PSI and recovers it; the Bissell is a 2-motor deep-cleaning extractor.

Which side blows as well as vacuums?

The shop vac side: both the STANLEY and the VEVOR state 3-in-1 vacuum and blower functions.

Which has the most airflow?

The sandia at a stated 100 CFM, against 85 CFM on the STANLEY and 65 CFM on the VEVOR.

Which state a warranty?

The STANLEY: 1-year limited. The sandia, Bissell and VEVOR state none.

Can the extractor replace a shop vac?

No: it washes fabric and recovers solution, but it does not do dry debris and blower work like the shop vacs.
