| Portable Electric Drum Machine | 30–100 mm (1.2–4 in) | Indoor sinks, floor drains, kitchen lines, small branch drains and short residential blockages. | Ground-fault protection, emergency stop or foot switch, enclosed rotating drum, cable anti-whip control and insulated handles. | Clean and disinfect the cable after use; inspect for kinks, corrosion and broken wires; lubricate the cable and check belts or switches regularly. | Approximately US$2–6 per operating hour | Basic to intermediate | Medium | Limited reach and cleaning power; rotating cable can expose operators to entanglement and contaminated wastewater. |
| Portable Electric Sectional Machine | 50–150 mm (2–6 in) | Longer building laterals, commercial branch lines and recurring blockages requiring stronger cable torque. | Foot-pedal dead-man control, cable torque limiter, transport guards, insulated controls and a stable frame or guide tube. | Wash and inspect each section after use; check couplings, bearings, guide springs and electrical protection; replace worn cable sections promptly. | Approximately US$3–8 per operating hour | Intermediate | Medium | Heavier and more difficult to transport; incorrect coupling or excessive torque can cause cable separation or injury. |
| Gasoline-Powered Drum Machine | 75–150 mm (3–6 in) | Outdoor service work, municipal cleanouts and locations where electrical power is unavailable. | Engine exhaust management, fuel shutoff, belt and pulley guards, emergency stop control, secure drum cover and low-vibration handles. | Engine oil and air-filter service; fuel-system inspection; cable cleaning; belt, clutch, bearing and fastener checks. | Approximately US$5–12 per operating hour | Intermediate | Low | Produces exhaust and noise; must not be operated in enclosed or poorly ventilated spaces. |
| High-Pressure Water Jetter | 50–300 mm (2–12 in) | Grease, sludge, scale and silt removal in service laterals, commercial drains and municipal sewer lines. | Pressure relief valve, trigger-gun dead-man control, hose safety whip check, non-return valve, thermal relief valve and clearly rated hoses. | Flush and inspect hoses and nozzles; check pump oil, filters, fittings and unloader operation; winterize the pump in freezing conditions. | Approximately US$8–25 per operating hour | Intermediate to advanced | Medium | High-pressure water can penetrate skin and cause serious injury; requires exclusion zones, protective clothing and trained operation. |
| Trailer-Mounted Water Jetter | 100–600 mm (4–24 in) | Long sewer runs, larger commercial systems, municipal maintenance and heavy deposits. | Pressure relief and bypass controls, hose reel guard, emergency shutdown, secure chemical and fuel storage, trailer brakes and lighting. | Daily hose and nozzle inspection; pump oil and filter service; engine maintenance; tank cleaning; trailer tire, brake and coupling checks. | Approximately US$15–40 per operating hour | Advanced | Medium | Higher purchase, transport and maintenance costs; requires suitable access and secure parking. |
| Vacuum Excavation or Sewer Vacuum Unit | Access pits, manholes and pipelines up to approximately 900 mm (36 in) | Removing standing water, sludge, debris and excavation spoil around sewer access points. | Vacuum relief valve, tank pressure gauge, hose restraint, emergency shutdown, safe discharge controls and confined-space procedures. | Inspect vacuum hoses and seals; clean filters and tanks; service the blower or pump; inspect hydraulic systems, valves and chassis components. | Approximately US$25–70 per operating hour | Advanced | Medium | Large footprint and high operating cost; does not replace cutting or descaling equipment when deposits are firmly attached. |
| Sewer Camera Inspection System | 50–600 mm (2–24 in), depending on camera head and push-rod size | Locating blockages, identifying pipe defects, verifying cleaning results and reducing unnecessary excavation. | Water-resistant camera head, cable strain relief, electrical isolation, stable reel brake, locator warning and bright, glare-controlled monitor. | Clean and disinfect the camera and push rod; inspect the cable jacket; check sonde operation, reel bearings, connectors and battery condition. | Approximately US$1–5 per operating hour | Intermediate | High | Diagnoses problems but normally cannot remove heavy blockages by itself; camera heads may be damaged by sharp edges or excessive force. |
| Mechanical Root Cutter | 100–300 mm (4–12 in) | Removing tree-root intrusion from sewer lines when mechanical cutting is appropriate. | Torque-limiting clutch, guarded rotating shaft, dead-man control, secure cutter attachment, reverse function and operator protection from flying debris. | Inspect cutter blades, shaft, couplings and bearings; remove roots and debris; sharpen or replace cutters according to wear. | Approximately US$6–18 per operating hour | Advanced | Low | Can damage fragile, cracked or unlined pipes; requires confirmed pipe condition and careful control of cutting force. |
| Battery-Powered Compact Drain Cleaner | 30–100 mm (1.2–4 in) | Short indoor service calls, occupied buildings and locations where low noise and quick setup are priorities. | Battery thermal protection, electronic overload cutoff, guarded cable, emergency stop, low-voltage warning and secure battery locking. | Clean and disinfect the cable; inspect the charger, battery contacts and cable condition; store batteries within the recommended temperature range. | Approximately US$1–4 per operating hour | Basic to intermediate | High | Limited runtime, torque and reach compared with larger corded or engine-driven machines. |
