the best robot vacuum cleaner sale online

The advantage of a canister robot vacuum cleaner with a carpet nozzle is that the motor in the canister is stronger than the motor in an upright vacuum cleaner. The canister vacuum motor is a Flow-Through motor, meaning that the air travels in a straight line through the moror and then out the exhaust. Upright vacuum cleaners us a bypass motor. Meaning that the air must travel around the motor to exhaust out the back. This is less efficient than the canister motor. This is why canister vacuums have more suction. It should be noted that there are upright vacuums that actually use a canister style motor. The Riccar uprights almost exclusively use this type of motor also.

The canister vacuums also usually have a quieter motor, due to the sound insulation around the motor. The Riccar Pristine model has a very quiet motor, and can actually be adjusted to vary the suction power.

The robot cleaner itself is a sleek design allowing for ease of use around corners. The bumper is rubber and completely surrounds the vacuum. The bottom of the vacuum has four swivel castor wheels to allow complete maneuverability. The bottom is also polished to allow a smooth surface. With even the thickest shag carpet, the Pristine will roll easily across the carpet.

Where the Riccar Pristine shows real advantages is in the per nozzle, the part that has the revolving brush, and sweeps the carpet. The belt that drives the roller brush is cored with steel cables, much like radial tires. This makes the belt almost unbreakable.

The roller brush itself is stainless steel with sealed ball bearings on each end of the roller.
