Agitation and recovery do different jobs
A powerbroom or rotary brush agitates fibers and debris. Extraction equipment applies and recovers liquid. A vacuum collects suitable dry material. A process may need more than one tool, and a machine’s appearance does not establish cleaning depth. Ask what each step is intended to accomplish.
Compare systems in context
Truck-mounted systems can supply cleaning and recovery capacity through hoses; access, hose length, technician settings, and water management affect results. Portable systems can suit restricted access but differ widely in capacity. Pressure washing moves water and soil but does not itself provide vacuum recovery. Ask how displaced material and runoff are managed.
Protect the turf system
Brush stiffness, rotation, water pressure, nozzle distance, heat, and repeated passes can all matter. Ask how settings follow the turf manufacturer’s guidance and how the provider checks infill levels and seams before and after cleaning. A damaged base or drainage defect may require work beyond cleaning.
Start with the material that needs to leave the lawn
Loose leaves, embedded dirt, liquid contamination, and damaged infill are different problems. Ask what material the provider intends to remove, where it is located, and where it will go. A machine can move material without collecting it. A treatment can change odor without removing the underlying material. A complete explanation connects the problem, the action, the removal route, and the final check.
Equipment comparison at a glance
Use this table to understand roles rather than select a universal winner. Actual performance depends on the model, attachments, operating conditions, and the technician.
| Equipment | Primary role | Important limitation | Ask about |
|---|---|---|---|
| Powerbroom | Agitate and groom fibers; loosen debris | Does not automatically collect loosened material | Brush compatibility and debris removal |
| Rotary scrubber | Agitate with a rotating attachment | An unsuitable brush or setting can stress the system | Downforce, edges, seams, infill |
| Pressure washer | Apply directed water to dislodge soil | Does not inherently recover wastewater | Pressure, nozzle, distance, runoff |
| Truck-mounted extractor | Supply solution and vacuum recovery through hoses | Access, hose losses, setup and turf compatibility matter | At-tool recovery and complete process |
| Portable extractor | Bring solution and recovery equipment close to the job | Capacity and available electrical supply can constrain work | Vacuum configuration, tank cycles, circuits |
| Dry / wet recovery unit | Collect appropriate debris or liquid | May remove useful infill; capacity varies | Filtration, material separation, disposal |
Understand the numbers before comparing them
PSI describes pressure; it does not tell you vacuum recovery. Gallons per minute describes liquid flow, which also needs to be managed. CFM describes airflow, while water lift is a measure of suction pressure under a specified test condition. Peak brochure figures may use different test conditions and are not a measurement at your lawn. Ask what the system delivers through the actual hose and attachment arrangement.
- Compare the same units and stated test conditions.
- Ask whether a specification concerns a motor, a whole machine, or the working attachment.
- Separate solution delivery from vacuum recovery.
- Do not treat maximum pressure or temperature as a recommended turf setting.
Match the setup to the access
A large truck-mounted unit can remain at the vehicle while hoses reach the lawn, but parking, hose routes, lengths, and nearby doors matter. A portable can work closer to a restricted-access area, but it may need electrical circuits and repeated tank servicing. Ask the company to describe the actual route and staging location before assuming either system is workable.
Compare a complete method, not an equipment contest
Ask each provider to describe inspection, dry debris removal, agitation, treatment where appropriate, liquid application, recovery, grooming, infill checks, and aftercare. If a step is omitted, ask why. A company may reasonably choose a simpler method for a light maintenance job. For a recurring problem, the explanation should show how the chosen process addresses the source and what remains outside its reach.
Protect the investment during the clean
Identify loose seams, thin infill, sensitive edges, repairs, nearby plants, and drainage concerns before work starts. Ask how the operator chooses settings and checks results. Commercial strength is not permission to use the highest setting. A suitable small-area demonstration or inspection can help resolve compatibility questions, but it is not a substitute for manufacturer requirements or a complete written scope.
Your practical checklist
- Problem and removal route defined.
- Agitation and collection explained separately.
- Actual model and attachment identified.
- Access, power, water, and wastewater arrangements confirmed.
- Turf-compatible settings and infill checks included.

Common questions
Which machine cleans deepest?
There is no defensible universal answer without knowing the turf system, contamination, access, and method. Surface recovery does not prove that material below the backing has been removed. Ask which layers are addressed and how the provider verifies the result.
Is more suction always better?
Useful recovery matters, but the whole setup must suit the turf. Attachment design, airflow losses, infill handling, and technique affect the outcome. A high maximum rating alone does not describe the conditions at the surface.
Why do two companies propose different equipment?
They may be pricing different scopes, interpreting the concern differently, or working with different access and capacity. Have both explain the problem they are addressing and the limits of their method before comparing totals.
